I have a pilots watch that even has a slide rule built into the bezel. No batteries and no manual windup. It's such a complicated hefty thing to look at but I love it. I bought one for my brothers 50th birthday and one for myself too.
I had to laugh out loud when you started pulling out old vintage glass. Something more than ten-years ago I bought a Sony NEX-5 and the viewfinder. I learned about adapting vintage glass and now have a ton of it. I just looked and there are a couple of Industar and Helios pieces still on my shelves. I have a little Industar 50/3.5 that is a fascinating and tiny bit of glass. It's amazingly sharp. I also have a Schneider 50/2 (?) that fits a Retina. It has amazing bokeh. Now I might have to pick up a couple of Jupiter and Industar pieces. I'm a Fuji shooter, by the way. But I think a Hassleblad 500CM is somewhere in my future for shooting medium format film.
😀Wonderful, the Catalog's were really interesting. I managed to pick up MTO-500 and MTO-1000 mirror lenses over 10 years ago in M42 and at the other end a Zenitar 28mm fisheye lens in with PK mount.
Zeiss was splitted to GDR Carl Zeiss Jena and western Carl Zeiss (afaik Oberkohen). And Soviets were not only copying German optics, but built them before II WW by license eg. Leica camera was made there as FED. They copied eg. Contax, which was manufactured as Kiev (range finder camera).
I have Jupiter 8, 11, 12, Industar 22 and 61 and some more. I love them all very much. All Leica LTM mount and use them on a Minolta CLE. I also used them first on a digital Fuji EX-1. Now with film on the CLE.
Your toy box is very similar to mine. While I enjoy your technical content, your toys are way cool as well. Most engineers I know (self included) love complex toys i.e watches, cameras, telescopes, audio gear etc.
Thanks for an interesting video. I have a Leica camera and some lenses which I actively use and am very interested in older lens designs and the resulting character they give to a picture. Those catalogs are certainly of great value to explore these older lenses. I would like it if you do a few more of these videos.
I grab any old Zeiss optics I see for a decent price, even if I don't need them. I even have a bunch of laser-optics sitting here that I don't know what to do with.
Your channel just got better! As the Sr Product Engineer for LUMIX, I really enjoy seeing our customers using these vintage lens. I seem to recall you are using a GX8? Have you ever tried the MFT pin hole lenses?
As I recall, I had just invested heavily into my Canon SLR, lenses and color processing darkroom equipment just before film photography became obsolete and I switched to digital. Kind of disappointing because of all that nice equipment going to waste. But those were fun and fascinating times exposing and processing films, especially doing B&W as a kid.
I had a question, you seemed well versed in optics and electronics. I have been curious if there could be a way for software to compensate for out of focus screens. Like taking off my glasses to see blur like normal and then a TV screen set to my prescription in the distance that's clear. I'd imagine this is closer to science fiction than anything, but I was just thinking about it.
I have a Canon EOS Rebel XT DSLR camera from my parents, I use the lens it came with and it works pretty nice. I've thought about finding other lens to use. One day I might just do that.
I thought Compur just made shutters. Those DOF indicators are cool. I never got into the Russian stuff. I am a Minolta and (and now Sony) collector. I have about 10 SLRs and 30 lenses, also RFs and TLRs. If you want to look at Minolta lenses, there are lots of online resources. And Minolta lenses are dirt cheap now. BTW my actual everyday camera is a Lumix LX100 which has a M4/3 lens but not interchangeable.
Yes Barry you are right, Compur was the name of the central shutters from the Deckel company and at the time this lens is from they started to design central shutters to stay behind the lens for interchangeability of the lens. As you can imagine the central shutters has to open and shut very fast and therefore the size was restricted. So they ended up with a certain width of the last element and that defined the minimum apperture of the lens. To make it all work they developed the bajonett along with it as the shutter was more a part of the bajonett than the camerabody and the lenscase part of the whole design of shutter and bajonett. That opened up some options for automatic exposure as the apperture was driven from the cameraside (hense the adapter shown has an apperture control ring). On the other hand there were no telelenses with low apperture possible, the opening was to tiny. For some time these were anyway selling good on viewfinders and consumer slrs but the thurst for lowlight photography pushed the planeshutter ahead, working direct in front of the filmpane offering wider bajonetts (like minolta desgned). Nevertheless one other aspect should be mentioned that centralshutters are in sync with flashes at any speed while the planeshutters in the sixties usually ended up with 1/30 or 1/60 being in sync. So you can shoot with flash at higher speeds and reduce influence of natural light. But on the other hand powerfull electronic flashes were bulky and expensive. In the end the compur shutter behind the lens was an interesting development of the time and on the long run was one of the reasons why the german cameraindustry didn't catch up with the japanese. Nevertheless the lenses are nice, if you have a camera and film these are charming and I'm very much looking forward to use some in the next future.
@@alyro-ls1dv Thanks. I knew about leaf shutters vs FP ones. Incidentally, the Pentax 110 SLR has a combined shutter/diaphragm. Take your two first fingers on both hands nail-to-nail and slide them together. The aperture gets smaller as you slide your hand together, and the speed in which you slide is effectively the shutter speed. Quire clever, although of course complicated. But cheap to make. I have all the generations of Minolta DSLRs as the mirror technology evolved. First it moved like a film camera, then it did not as it was semi-silvered and sent some of the light to the viewfinder and most to the sensor, then all electronic with no mirror at all. Then Sony changed the lens mount from A, which was Minolta compatible to E which was new and reduced the focal plane to lens distance and allowed a smaller camera, and I think allowed other advantages. One is that it is easy to now adapt many other lenses, M39's, Canon, etc. But I must use an adapter for my 25 Minolta lenses. And there are four different adapters! Anything to make you spend more.
Hello, I m sorry if this is the wrong place to post this but in your video 1366 RF BRIDGE looking at the schematic you drew and the oem one how can this work the DUT and the REF are both grounded at the output and so is the input after the resisters. I have one of these and just can't get it to work what do you suppose is wrong with this, is the schematic right? I would appreciate for your help on this.
@@IMSAIGuy Yes I believe the schematic that you drew is correct. The schematic that is OEM has everything grounded can that work like that. And if it does can you explain how those grounds don't matter or do matter

Great piece on Russian lenses.

I've got the GX7. have not tried a pinhole on it but it has had a lot of very strange lenses attached.
@@IMSAIGuy I’ve worked with doctors who have used it with medical devices that go where the sun doesn’t shine!
I love my LX100. I have an LX5 as well. Everything else is Sony!

Kind of disappointing because of all that nice equipment going to waste. But those were fun and fascinating times exposing and processing films, especially doing B&W as a kid.
Film is NOT obsolete, in fact it is trendy. Kodak even restarted production of Ektachrome.

I don't think anyone mass-produced a digital back for any camera. 35mm anyway. They would all rather sell you a new camera, after all.
