I've just developed my 2nd roll I've put through my new OM2n, and the negs are horribly thin, and I can't work out why.
First roll was tri-x, shot with a 50/1.8, developed in hc110 - came out perfect.
Second roll was Adox CHS 100 shot with a 35/2, developed in Rodinal, negs are very thin (and yes, I did remember to change the ISO setting).
I'm using sr44 batteries. I've checked the meter against another camera and a lightmeter, and the internal lightmeter seems ok.
I think the neg is under exposed rather than under developed - however I had just opened a new bottle of Rodinal, bought about 2 years ago. I did 10mins with 1+50, as per massive dev chart, as I always do.
It's the first time I've used the 35/2 - could that cause it? The aperture doesn't close when firing on f2, and a lot of the negs were shot at f2, so I don't think that is the problem.
I know, I need to do some test with different lenses, film and developers, but can anyone see anything obvious here as to why I'm getting this problem?
