I bought an old Praktica MTL-3 and I'm gonna see what's inside/how it works. It's a 40 years old 35mm film camera manufactured in Germany and it came with "Carl Zeiss Jena 50mm F2.8 Tessar" lens.

Concept of this video was inspired by channel JerryRigEverything, but instead of opening new phones I disassembled an old camera. Second person who motivated me to do this video, was also Lew Later from Unbox Therapy as his excitement for technology brings happiness to the world.

The camera is indeed a mechanical camera, the batterry is for the light meter. awesome video congrats!!!

Thank you for this! It's a really clear guide and super useful! I just got one of these and three lenses from a friend's dad. They're all a little grubby and have a little fungus but physically in great condition. I was able to open and clean the insides because of this video.

I already took apart dozens and dozens of cameras !!! (and at least one the this model). Special "spanner" tools mey be required to void damaging parts, and some screws are left threated, keep that in mind if the screw doesn't move.

Great and interesting Video ! I use several MTL and LTL Prakticas since long years. They are very reliable and sturdy cameras. The light meter on the Prakticas is very exact and reliable too. I can highly recommend these cameras ! For beginners with film shooting i recommend MTL3 or MTL 5 /MTL 5b/ MTL 50 cameras. The older LTL or LLC cameras are technically the same, but the viewfinder was a bit darker and a bit narrower.

Thanks for the video! It was very helpful as a reference for taking apart an LTL-3, which is almost identical. Unfortunately my camera has a lot of moisture damage, with different colors of rust everywhere! Mechanically it is sort of working, but it will need a lot of cleaning to be reliable. The hole under the shutter button is for a self-timer, which is present on the LTL-3 but apparently not the MTL-3.

I think MTL-3 had three different versions and some of them had it. (found some old magazinse photos) Good luck with the cleaning tho :) (and thx for the comment)

Thank you, I have a similar model and my problem was shutter that stuck when you chose a shutter speed lower than 1/8 second. I disassemble the camera and drip several micodrips of machine oil to this gear mechanism and now everything works well)

Thanks for the video, you helped me fix my MTL3! Mine had a stuck trigger that released part of the shutter mechanism every time you pulled the lever, putting it in a state where you can't pull the lever anymore and you can't take a picture. A drop of sewing machine oil fixed that for me

At around 9mins when you accidentally close the back door. Just to say if this ever happens to anyone, to use a paperclip like a hook to lift the mechanism for the door through the hole at the top. Just something i picked up years ago.

@andrewcomerford9411 6 ай бұрын

The MTL 3 is an all-manual SLR, but it has TTL metering. The heavy piece is the Pentaprism - solid glass - and the object next to it is the cell for the meter (actually a resistor, but that's another story). The hole in the front, below the shutter release, was for a self-timer.

my camera seems to be working fine, but it's just that piece of plastic or glass which has dirt in the viewfinder which is bothering me! Otherwise, I can still compose images just fine... Do you think it'd be worth the effort to clean it out?

@Gamenomaly 3 жыл бұрын

Speaking as a guy who doesn't know much about cameras and did this video just for the curiosity of it -> If it's just the glass of the view finder that is dirty I'd say it's doable. But if it's the whole glass triangle shaped block... I would prolly avoid it. (If you start taking it apart. I would highly recommend keeping track of all the pieces)

@andreasklindt7144 3 жыл бұрын

Replace the battery to a new one! When the battery is too low the lightmeter has not enough power to measure correctly. Quick, easy and cheap fix for that. ;) The type number of the battery should be printed on it, but in case you don't have the battery anymore: It's a LR44 that is also often used in all kinds of small electronics. You can find it on amazon or WalMart (I guess, I'm not from the US or Canada). But this battery should be easy to find.
