We had signed up for the November 2020 Joshua Tree Half Marathon but the pandemic happened and the race was canceled. We decided to keep the Airbnb and escape any way. It’s in the middle of nowhere so except for buying take-out and booze we didn’t need to interact with anyone. A nice short trip to shake off the stuck-at-home blues. We wandered around Palm Springs in the rain, visited the Salton Sea, and did a fun hike in Joshua Tree National Park. We had to quarantine when we got back but it wasn’t much different from life before so it was definitely worth it.
Minolta SR mount is the same bayonet as MC & MD but with no meter coupling or smallest aperture lever.
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.
I realized that 13 weeks is 1/4 the way into the project! Time flies when you’re having fun.
Fujicolor 200 film. I used the ‘A’ setting for pretty much everything on the roll. I could have written down the aperture from the viewfinder and then the shutter speed from the ring on the lens as I went but I didn’t.
Something I didn’t mention in the introduction — the viewfinder does parallax compensation. Because the view isn’t through the taking lens like an SLR, close framing can be off because of the distance between the viewfinder and the lens. The frame lines in this camera move to correct for this. Pretty sophisticated for a camera originally released in 1972.
And an error in the intro — you don’t get metering without a battery but the camera will work. I mashed it up with the Canonet 28 (I still don’t have the meter working in that one) which is crippled to 1/30 sec. shutter only without a battery.
