One note about selenium light cells: they wear out with use and time. There are plenty of these cameras out there where the cell isn't as sensitive so it over-exposes everything, or sometimes the cell is completely dead and the camera won't let you take a picture. That said... I'm not entirely convinced this is so common as to be expected. You might have noticed there are... more than three of these cameras littered about. I have purchased several cameras listed as non-functioning or "for parts" or whatever and I personally have only encountered one which had a worn cell (it's actually the cell you see disembodied in this video). I suppose I could just be quite lucky, but one of those parts cameras was absolutely trashed - rusty, moldy, and seized up - but the needle was just as perky as the rest! Specifically with this design, if the aperture blades cannot open, the shutter interlock / red flag does not work. That makes a lot of people presume that the camera is dead. But! If the shutter still fires, you can usually test the meter's integrity by shining a bright light into the lens and listening for that faster shutter speed. If it's changing speeds on its own, the light cell and meter are working - but the stuck aperture mechanism might fool you into thinking it's not.

I managed a camera store for 16 years and we found that sometimes a dead or lazy selenium meter could be "shocked" back to life be exposing them to direct sunlight for a period of time. I have a few Gossen and Sekonik meters where this has worked. I also have a Petri 7S from the mid 60's that has a working around the lens that still has a working selenium meter, but I also have dead ones.

When I was 5 years old, my father got a state department job in Japan, so our young family packed up and moved there to live for several years. My folks has little expendable income, by my mother insisted on buying a new Japanese camera for herself to use for all the family & touristy things she envisioned. Being frugal, she wanted to conserve on film costs, and selected the Olympus Pen (this would have been around 1963) as it did the half frame exposure and also was simple and nearly foolproof to use, and reliable. Later, we moved to Europe and lived in three different places for many years, and she hauled the Pen camera all over, taking lots of photos. Recently, I spent a few months scanning all the old family slides, and found a few thousand of the half frame slides (my mother never seemed to have a problem with the photo labs being able to detect, appropriately process, and correctly frame the smaller slides). There was not even a single poor exposure in the lot, and they were all in focus. She still owns the camera, but has not used it in many decades.

@PT , I don't know. He never talked about it. I know he had a secondary duty to make certain announcements on the Armed Forces radio network (Pacific), but that was not his main reason for being there. He had previously had a couple of duties at Cape Canaveral related to the early Air Force missile program, so I thought he might have been given some related duty in the Pacific region.

@p be but cameras were limited by their design in the past. There's no reason every digital camera shouldn't let you take photos in any dimension in the most comfortable orientation. It might mean being forced to use a lower resolution, but why not let people have the choice? Nobody needs 32 MP really...

@the commenter Yes, totally agreed that would be good, BUT ONLY if the user can disable it. The user has the right to create the effect of a world cranking over clockwise, on an axis through the camera, by changing his camera's horizontal level in a counter-clockwise direction. I didn't move over all my software from an older computer, and now I have nothing that disregards EXIF. So I have no idea, until a few people who are still using software (old browsers and such) to view photos write back to me and TELL me "this photo is turned 90 degrees". Even the latest version of MS-Paint won't ignore EXIF. I DO have an OLD version of MS-Paint, and it DOES ignore EXIF. But the JPG file-format is lossy, so there is always going to be some degradation when I open a JPG in Old Paint, save as ".bmp" (which will lose the EXIF business), close it, open it again, turn it sideways, and save it as JPG so that no matter who is using what software to look at that image, it's not turned the wrong way. Another fun effect in a photo has been done retroactively with videos of rock-bands in the 1960s. The video is edited so that it looks as if the original cinematographer was either swaying or jumping in time with the music, or flicking the zoom knob in and out in time with the music, or both. A user should be able to impart a rhythmic effect like that at the time of filming, perhaps not up-and-down or in-and-out but swiveling. A sensor that preserves horizontal orientation would prevent a users' doing that.

For the background of the design choices for this camera, look up the designer: Yoshihisa Maitani. He was a passionate photographer and felt that the half frame format let him take twice as many pictures for the same cost. He also designed other influential Olympus cameras including the OM1 and the XA series.

Sort of tangential, but I've thought about the reason why the current era has returned to taking photos vertically on their phones (and has started taking vertical videos) is a matter of general ergonomics and the push for thinner devices with larger displays. So while nearly every smartphone prior to the iPhone 6 was a lot easier to hold one-handed, in either orientation, the iPhone 6 was the first phone to really be hazardous to hold in landscape orientation due to it coming in a fairly large size, having a rounded bezel, and being made of slippery, expensive materials that happen to take dropping kind of poorly.

While I love the OM series, the ingeniousness of the XA (such as their having to use a "reverse retrofocus" lens design to be able to fit it under the sliding cover, and the sheer audacity of implementing a rangefinder mechanism AND aperture control in a camera THAT small) along with its utterly unique look (with its iconic Big Red Button), make it one of my favourite examples of industrial design of all time.

Yes, Maitani was a passionate photographer, and that shows in many of his designs, and design choices. It is part of why even the 'point and shoot' PEN models have those excellent optics.

Half-frame 35mm is larger and better resolution than Kodak Disc, so I don't think its failure to catch on was a quality issue. And composing pictures in a vertical format doesn't seem to be an issue for most people (smartphones have shown that, for better or worse). So it's surprising that this was a niche format, you would think less fumbling with loading film would have been a big selling point.

In the 80s my mom had a modern version of a split-frame camera. It was extremely convenient for travelling and taking a lot of pictures (which was part of her job doing research). The limitation was developing - not every film place would do it, and sometimes they'd be done really badly (like just half-sized photos). Was always a bit hit and miss. And the quality wasn't great using 400 film (which was the most widely available). It just wasn't as forgiving as a more robust 35MM point and shoot.

@Dribbleondo Google's requirements for Android (or actually should I say, Google Mobile Services) licensing actually state that any cameras a smartphone has, MUST have the same orientation (i.e. portrait vs. landscape) as the screen, and therefore the phone's body. I guess they know what they're doing - this PEN doesn't follow this convention, which probably tipped people off. Come to think of it... Maybe this precise requirement is the reason for the awkward aspect ratios of Android foldables? I mean, if they opened from portrait into landscape, the cameras couldn't stay in the right orientation for both screens. So they make them so skinny so that they could stay in the same orientation when opened. Maybe.

In my decades as an Olympus tech, I worked on literally 1000's of these -- they were actually quite popular. All in all, a remarkably well presented program. One minor point -- what you call "feelers" are typically referred to as "step cams". And I could provide some tricks for setting focus.

@AplaTaSpaw if the film transport is stuck, and that isn't a simple case of it already having been wound and ready for the next shot... you need someone with good mechanical skills to look at the camera. Check Olympus for the service manual if you are that person yourself, it has the details you need for doing a repair. A common cause however is debris from light seals ending up in the mechanism. If that is what has happened to yours, it might still be fixable, but that often is a very involved repair, requiring complete dismanteling and rebuilding of the winding and shutter mechanism.

I had a photo business with a busy used-camera section. I had one of these myself, and they never stayed on the shelf for long. Often people would bring in Grandads 'old cameras'. Trips were popular and it was a treat to find a half-frame. ( And the odd Leica.. )
Bart Van Leeuwen
Bart Van Leeuwen 2 aylar önce
@Kaitlyn L There are 2 problems actually. - Getting the display/focus screen in focus (ideally with your eyes focusing for infinity). This is easier with an EVF, and much helped with a diopter adjustment. - Being able to see the entire frame. This can still be an issue with modern EVFs. The problem is this is always a compromise. Too long eye relief causes problems for people without glasses (eye strain, difficulty centering the frame, light leakage), too short means unusable with glasses. With many classic SLRs, you get a protective rubberized ring of sorts around the viewfinder (and its usable with just that), and have a variety of optional eye cups, the ones you typically want for use with glasses are both flatter (to get closer to the viewfinder), and wider, so to keep stray light out of your eye. I have a Hasselblad 500 around with a 45 degree angle finder... Of course Hasselblad doesn't care about how big things get, so they just solved this by providing very generous eye relief and a giant replacable eye cup, which is really adaptable to whatever needs you happen to have (including correction lenses and such)

*Good video and an excellent explanation.* Some cameras, such as the Konica EE-matic Deluxe (c. 1964) had an even more complicated mechanism, based on similar, trapped needle metering principles, that varied both the shutter speed and aperture simultaneously, according to a kind of mechanical 'program'. For the Konica, the shutter speed is displayed in the viewfinder. It also included rangefinder focusing. See also my reply on selenium cells to TC's pinned comment.

wow, this brings back memories. I remember my grandmother had one of these and she used to take her reels to a kodak booth that later closed down. And after awhile, the film became almost impossible to get developed correctly at walgreens. She also had this compact beige rectangle sort of camera that you'd push one end and the lense would pop up from the other. To this day I wish I knew what it was called / who made it. As a kid, I always thought it was a transformer as it had so many moving parts.

Your argument that, because half-frame stills are the same size as what gets projected for motion pictures the quality is similar - is flawed. Resolution isn't as critical for video as it is for still imagery. Consider that 4K video is less than 9 megapixels. Can you still get perfectly fine prints? Sure, just at smaller sizes. Less surface area = less resolving power.

Oh hey, I correctly guessed how all of the mechanism worked! I didn’t guess the _layout,_ but still. Quite pleased with that. Admittedly I already knew how those light-meters worked, and indeed they are the same as a thermocouple-based electronic thermometer, just with light instead of heat. So I had a head-start, and didn’t have to guess anything about the first half. Still, definitely pleased with guessing that they used the needle, and some mechanism to interrupt the aperture plates based on the needle’s position :)

Before getting offended and firing off vitriol at him maybe take stock of what you said when you said "context matters". people will take things literally. Though you are correct, taking the whole electronics did exist argument and tossing it out the window, the electronics needed to perform the function of deciding aperature size and shutter speed automatically in this form, they didn't exist, i mean transistors had just barely been created at the time and they werent cheap, nor efficient, if they had somehow succeeded this camera would have been almost twice the size and needed some real battery to be able to run, still would have been impressive, but this solving it mechanically thing is much more impressive.

@OvertravelX oh my yes, i got started with the mechanical setups of older elevators from schindler like the wheel the otis carrier train and selector tape, and caught some videos of older telephone switching mechanisms and its just flabbergasting, especially since at least with the elevator controllers they still tend to work, i know a lot have gone to scrap, but theres still some floating around... shame that ion todays world people think its just better to retro fit the systems with basic crappy logic, that doesnt make the elevator better or more efficient it just makes it slightly more reliable with no more 40 year old components and slightly easier to repair when all you have to do is watch a log and see why the elevator safety braked, much easier to just see a log that says door interlock trip, instead of having to go through all the relays, reset the entire controller and see if the fault can be replicated. still sad though, always fun watching the relays go click and clack as the elevator picked up calls.

@Marc Kyle Where? They don't exist where I live. Film will die out as fast as the vinyl. The only way I can do this is strictly through mail order or driving 60 miles to a camera store, if they offer the service. While station in the Philippines in the early 70s, we had a photo hobby shop where we could develop black and while, print black and white and develop color Ektachrome slides. That was fun and convenient. Now I do it all home with my computers and color printers. If I was a pro and did portrait photography I would get back my Mamiya RB67. Maybe even play with a 5x7 and 8x10 view cameras. But my game in the military was news style photography. Being overseas a number of times and in different states offered lots of opportunities for great photography, mostly for memories and people I met. Now I am into grandkids and family stuff. I would say the best time I had was doing news style photos. Nothing is ever the same, you meet new people all the time, and find yourself immersed in activities like young airmen working on fighter jets, etc. Might even find yourself at the DMZ between North and South Korea or tripping to Mt. Fuji. That was my life.

Would be nice if stores started carrying film and there were labs here and there to process the film. I enjoyed film cameras for many years, but now days, I am so used to digital cameras I find it hard to move back to film. Once I started using my Sony A7R3 in manual mode, I became content and comfortable with digital cameras. Plus I like the ability to do shoot in video mode with the same body.

Just take the plunge already, but don't spend too much on your 1st gear. That way you can always change your mind, and can say you had the experience. I've restarted analog photography last year with a 3 dollar Soviet Smena Symbol camera, and a 4 dollar Leningrad lightmeter (though I've also used a phone app). And it was producing decent enough pictures to keep me going, and also got me understanding the basics of exposure. Now I'm using a Nikon F55 that my grandpa gave me, and worth like 40 bucks, but a bit too automatized for me, I loved the full manual control of older cameras. Though this makes better images, and can be used in manual mode for fun.

zachary carlson

Its genius because the needle doesnt need any strength... the first lever holds it in place to stop it jiggling if the camera is being handheld, the second lever selects the appropriate position by just just touching it, i imagine the mechanism uses levers and springs to translate the larger amount of force needed to move the aperature blades to the ever so tiny amount of pressure needed for the selector to stop when it touches the needle ever so slightly, the fact this is 1960s tech, all mechanical and robust enough to be in a camera that will get held in a hand while moving, slung in a camera bag or around someones neck while at the beach or something is quite impressive, especially since outside of some gunk after 40 years and the off chance that the selenium cell may wear out and cause the mechanism to stop working. these cameras just, work. Quite impressive.

@Emily Adams I sometimes find it easier to get people to remember which way around the its/it's distinction goes by showing them that it fits in with a general pattern: Possessive adjectives don't have apostrophes: my, your, his/her/its, our, your, their. Nor do possessive pronouns: mine, yours, his/hers/its, ours, yours, theirs. But contractions of the verb 'to be' do have apostrophes, to indicate the missing letters: I'm, you're, he's/she's/it's, we're, you're, they're. So do contractions of 'to have': I've, you've, he's/she's/it's, we've, you've, they've. Once they've seen that, they're less likely to see the its/it's distinction as an arbitrary decision that someone has made and is trying to force them to follow. (It also brings in the distinction in spelling of their and they're, which for many people - though not me, as it happens - are homophones. And your and you're, for that matter.)

@Cameron Webster There used to be a usenet group for English Language nerds called alt.possessive.its.has.no.apostrophe. Since you aren't allowed to have apostrophes in usenet group names, that lets you work it out. If it were the other way around, they'd have had to call it alt.possessive.it's.has.an.apostrophe, which would be illegal!

@Cameron Webster Possessive = its = Belonging to something. Example: The car stopped cos its engine exploded. It's = contraction of "it is". Switching the two is like saying "The car stopped cos it is engine exploded." I don't even know what "Its an expensive repair" would mean, if read literally.

Your video took me back in time. I always liked, when I was young, taking apart devices to get an idea of how it worked. More than 25 years ago I disassembled a similar camera, I saw the needle system resembling a vu-meter, resistor and electric wires and I couldn't understand how there could be any electronics without battery. I had falsely imagined that it worked in conjunction with a flash that we put on the shoe above. Thank you for bringing me back so far in my memory.

It's hard to compare, both are complex in their own ways and just because image processing algorithms are 'just calculations' run on a processor doesn't mean they don't require knowledge and intelligence to design, let alone everything involved in designing and manufacturing the image sensor itself etc. We just kind of take a lot of electronics for granted nowadays without reflecting on the massive amount of engineering that goes into each and every one of them. Of course there's a lot of beauty and finesse in mechanical solutions of the past but it's kind of like how you can appreciate a Rube Goldberg machine even though you could solve something with less moving parts

@Ryan Boyer It takes a remarkable number of transistors to build those basic simple operations into a useful microprocessor. Take the 6502: 52 instructions; just _one_ general-purpose register and 2 index registers with slightly different functionality; and the stack pointer register is limited to just 8 bits, yet it took 3510 transistors to implement it and another 1018 transistors arranged as crude resistors. This was all in NMOS logic where some of the many logic gates can be reduced to a single transistor depending on where in the circuit they are. This is a similar complexity to an entire fighter jet, but it's one of the simplest practical general-purpose microprocessors ever made. Some PIC chips may be simpler, but I'm told they're not very nice to use.

Well, microprocessors are repetitive. They have a massive amount of functional elements, but they consist of the same thing repeated over and over. You could build a digital clock out of mechanical components, but it would be the size of a building and it couldn't run fast enough. It would be much more complicated than a mechanical clock, but looking at it wouldn't give you the same kind of satisfaction. You can look at a mechanical clock and understand completely, how it works. That's the thing. Same with cameras.

Thank you for another superb video. I hope you can do another on the Olympus XA, one of the great product designs of all time, done two decades later by the same designer, Yoshihisa Maitani. All that fiddly mechanical stuff for exposure was replaced by some very simple analog electronics that calculate exposure times into the tens of seconds at least. Needs two tiny batteries but they last forever, since film advance, film rewind and shutter are all still hand-powered.

Great video, I have the very first model of pen that I almost always carry on me, with my pen being full mechanical with no light meter I defiantly expected a difference between the later models, but I'm still surprised by how different they are, on my pen pretty much everything mechanical about it is located directly attached to the lens and it comes out as one puck that can be operated outside of the camera. With everything on the puck it also made for a difficult repair because I had to disassemble all the way to the blades themselves and remove them to clean. Interesting how limited the EES-2 is as a manual camera, previously I was planning on buying a newer pen at some point to get a built in light meter, but now I think I'll stick with my current pen so I'm not stuck with only two shutter speeds. Unless one of the pens after yours has better manual options, something I might research later.

Great video. I've got numerous devices employing the trusty old selenium cell meter and to be honest, I'd agree with your statement in regard to the frequency of failure/issues with them. I've had a few meters where the contacts on the actual cell itself had corroded, however once cleaned & re-soldered they usually (in my experience) spring back into life with fairly decent accuracy. Whilst I much prefer shooting 120 / medium format, the compact form-factor of these style cameras is quite convenient. I don't have a half-frame camera, however my personal favourite is the elegant little Rollei 35S. Similar light metering mechanism to the selenium cells, but with a much more reliable photosensor. I very much enjoy the deep dives into the film photography side of things - I first picked up a film camera over a year ago and have well and truly fallen down the rabbit hole. Your videos have been quite an inspiration to learning about the processes and the very extensive history around it. I started with a half-broken Zorki-4, and now I've got two cupboards full of cameras ranging from the compact Rollei 35S I have already mentioned, several Rollei-derived twin-lens reflexes and right up to the large format 4x5 technical camera and iconic Crown Graphic. I am in no way making images I'd consider groundbreaking, sharp or well composed by the standards of many other photographers but getting to use and enjoy these amazing mechanical marvels every day is an amazing thing. I look forward to the next video on the subject!

As much as I admire the electromechanical linkages of the past, I completely understand why everyone uses microcontrollers now. It's just so much easier to modify the design. A mechanical design can perform its function flawlessly for decades, but what happens when you realize you need it to do almost the same thing, but with one tiny difference? You often have to redesign it. Whereas with a microcontroller you just change a line of code. It's just way too convenient for sentimental concerns to matter

Half-frame camera's demise was simply because manufacturers (especially Olympus) managed to produce Full Frame cameras that were the same size or even smaller. The Trip 35 as you mentioned, is a slightly larger Full-Frame version of the EES-2 with the same exposure function. The later XA was even smaller then then all the Pen cameras and managed to be a rangefinder rather then a zone focus like the Trip 35 and EES-2. Film economy wasn't as big a thing back then as film wasn't as expensive so extra frames could be seen as more of a hassle as it would be even more vaction pictures dad would have to take before he could develop the film.
