The film cartridge gives you 36 exposures, so you can easily take a picture of 14 or more places, "zones", landscapes, etc.

I think it was here, and yes, it was such a flame war...

Zones = Check out the Ansel Adams Zone system. The "dedicated silvermax developer" probably is tailored to the emulsion in a way that it gives good shadow detail and it's also able to fully develop the darkest areas. This is my guess. Probably other developers can do the same, but maybe the...

These electronic shutters (the ones on the ETR and SQ series) are very simple to service due to having few mechanical parts. I had a 75/2.8 MC with firing problems (i.e. shutter opened but never closed). I opened up the lens, got into the shutter from the front, cleaned the switches and...

I can't imagine this assembly working without a spring. It needs friction (it requires some slip) thus, i guess, it MUST require a spring to work correctly. Latest models (i.e. 4AM) have a fixed spool so maybe the slip is provided in a different way.

I can vouch that the film spool advance spindle has a lot of tiny parts: lots of washers, spring, etc. And on a Contax and a Kiev 4A i disassembled, it was completely dirty, grungy, you name it. A full disassemble is important for getting smooth operation.

You mean, before electronic testers? There's a leica shutter speed tester. It's essentially a stroboscope. A light source is inside a slotted cylinder. The cylinder rotates to a constant speed thanks to a synchronous motor. You observe the slits through the camera shutter and interpret the...

Thanks for advancing film emulsions 100 years into the future, despite what the flat-earthers believe. TMax and all flat-aspect-ratio-grain B&W films are great!

Aha! This is also what I was thinking. The only folder I kept, after having many, was a 6x4.5 folder with a tessar-type lens. Also,it has true film rails. It did give very sharp results. So from my point of view this is due to a combination of (1) better aligned front standard, (2) flatter...

This is interesting. I guess one would have to evaluate RF base length and magnification. A 50/1.5 and even 50/1.1 can be critically focused with a rangefinder like a Contax or NIkon, where the base length is big. Those are lenses with small DOF.
