The batteries in the Seagull have died, and I can't find the same batteries locally. So now, I can't use the internal metering. It's no problem for long exposure night shots, but for day, that's another matter. Have you heard of using one camera to act as the meter for another? So, if I find that for my KM, 100iso, f2.8, 1/125 is fine, then I could set my Seagull to f2.8, 1/125 with 100iso film, and feel pretty confident that it should work out much of the time? If you haven't tried it, don't go out now, for my benefit, I'll probably give it a go myself later this month, anyway (depending on what other have to say, here).
