No pics to post just yet, been (A) busy, and (2) shooting film when I can. I've sure been enjoying the pics I see here though.
Not MFNG-related except that it pertains to older cameras from before the invention of AF glass. I've been running a Wein mrb625 battery in my Nikkormat. That's a non-mercury zinc-air replacement for the original 625. I had read that it works well as a replacement for the original 625 but would expire faster. Mine finally died today after about five months. I consider that quite good.
I replaced it with an alkaline version with the same form factor because I had some available. I had to tweak the ISO up by about 1 1/5 stops to make it match the meter of the Z5ii and my phone. That's about half of what I had to tweak the F Photomic, but then the F uses two in series, So I'm figuring the Nikkormat is good to go for a while. I'll have to monitor the alkaline battery as it ages though. We'll see how the rest of this film roll turns out.
