For example, with 100 iso and a value of 15 EV the reading is right, if EV is 8 it overexposes 1,3 stops

In your opinion, when you see the camera open towards the end of the video, can you guess where to adjust the exposure meter?

Thanks everyone for your replies. I remembered having four 1.35V zinc-air hearing aid batteries. After the first reply, I connected them in series, obtaining a voltage of 5.4V like the 4 original Mallory PX 625 . Unfortunately, the light meter readings in low light are identical to those with 6V...

First of all, thank you for your reply and for the helpful comments you made. Along with the camera, I found two new 4LR44 batteries (6v) from the previous owner, and I thought they were fine. You're right; I see online that this camera used 4 PX 625 1.35V batteries, for a total of 5.4V. The...

I bought a 1991 Zenit Automat a month ago. It looked new and in excellent condition, but the light meter behaves strangely: when checking with an external light meter or in a bright environment, the aperture-shutter ratio is correct, but in low light it overexposes by a stop. Sure, I can use the...

Thank you very much. I've seen that non-Soviet adapter rings are dangerous for the camera and lenses, and you can't even find images of the Soviet ones. Soviet lenses with a K mount are very few, and almost only 50mm. Do you know which Western lenses with a Pentax mount (Pentax, Cosina, Tamron...

Thank you so much. I have many Soviet M42 lenses and I knew from reading the manual about the M42 to K-Pentax adapter ring, but I don't know where to find it and, I fear, the possibility of full aperture measurement would be lost.

For a few days now, as the happy owner of a 1990 Zenit Automat in excellent condition (well, its Helios is a patch of meadow mushrooms, but dismantling it and cleaning the lenses is done in a few minutes, while the exposure meter is being calibrated...), I have been asking myself, and I ask...

I'm buying some Astrum Photo 200 films in the 120 format. I've found several examples of Photo 100 film online (and they're very nice), but I haven't found anything for 200. Has anyone ever used it? Any advice?

Thank you for your link but I want repair the camera myself if possible. I love this camera very much. Even though it's heavy and bulky, the waist-level viewfinder is very bright and the lenses are excellent. A bit fragile, I learned to repair them myself. When the first one broke, I bought a...

Thanks for your quick and knowledgeable response. I'll try to study the drawings and text. I have the impression that lever 1 is not completing the loading cycle and is locking itself early.

Good morning. I have a strange (but important) problem with my Kiev 60: when I cock the shutter the lever does not move back and the mirror remains slightly raised from its correct position. If ( once the lens is removed) I push the mirror down with my finger it locks in its correct position...
