images and such will be here
I did cover the exposure sensor and not the flash sensor when I tested the flash. In the video I put my finger over the wrong one. The exposure sensor tells it whether to fire (and what f-stop/shutter combination to use) and the flash sensor tells it when to stop the flash if it fired.
Something I forgot in the video: The guide number (GN) of the flash isn’t given but the manual does give a range, 0.9-3m (~3-10 feet).
The light calculator: https://toolstud.io/photo/light.php
About Light Value (LV) vs. Exposure Value (EV): As I understand it (and I’m mostly self-taught so chime in on the YouTube comments if I’m way off), at ISO 100 LV and EV are the same. Light value is how much light is present in the scene. Exposure value is how much light you’re letting into the camera. At ISO 100, it doesn’t matter which you use because that’s how the units are set up. ISO 800 film is 3 stops (100 to 200 is 1, 200 to 400 is another 1, and 400 to 800 makes 3) faster than 100 so the EV is 3 stops lower than the LV – it takes 3 stops less light to give the same exposure to ISO 800 than it does for ISO 100.

Sometimes poking around on line I run into something that makes me chuckle or is just off and I grab it for later. Amazon makes me chuckle or is off often enough to get its own post.
Amazon is notorious for hounding people to buy more of things that are obviously one-off purchases – refrigerators, toilet seats, & the like. Their “AI” is as dumb as a box of rocks and not just for recommendations.
The video is about 2:40 long.
I got this message at http://cdegroot.com/photo/yashica/
I’d been to the site before but apparently it’s being worked on. I wanted to save the message in case it goes away. I grabbed part of the screen so the video is probably an odd size.
Good article: http://www.konicafiles.com/slr-bodies/-konica-fs-1-1979/
My description of the VF meter displays was as clear as mud.
Here’s a link to the manual: https://www.butkus.org/chinon/konica/konica_fs-1/konica_fs-1.htm
I paid too much for a Polaroid 80A kit because it had a “Polaroid Land Pictures” album with these shots in it. The 80A used Type 30 instant roll film and made images 2 1/8″ tall x 2 7/8″ wide (5.4 x 7.3 cm). Polaroid stopped making Type 30 film in ~ 1979. It might be a good candidate for conversion to 120 roll film. It’s not instant but it’s something.
Images scanned at 1200DPI on the Canon Canoscan 9000F and resized to 1024 wide for posting. I’m still tweaking the M42 bellows and I don’t have a good copy stand for prints any way.
The prints have serial numbers and frame numbers on the back so these are from 3 separate rolls.
I know I can buy a bellows, either an old M42 or a new really expensive Novoflex, but that’s no fun. Besides, this one was too beat up to use as-was, so it was either repair/modify it or recycle the aluminum and landfill the rest.
There wasn’t much room for captions in the video and they go by pretty fast so here are the 1st pass results for how much magnification I get with the 75mm enlarger lens:
Bellows retracted all the way: 0.66… (2/3).
Bellows fully extended: 1.92.
The test shots were done on a full-frame Sony A7. Full-frame is 24mm high X 36mm wide. I just tested vertically and took photos of a ruler and counted the visible millimeters. 24mm would be 1:1 (life size). It’s not terribly accurate since I had the camera & bellows angled on a tripod and hand held the ruler but close enough for a go-no go check.
I’ll add images and more rigorous test results or link to a new post if it gets too long.
The manual is still available from Canon.
