I have been using the meter for quite a while, and comparisons with the readings are right on compared with my handheld CdS. And it is just so handy being on the camera. Unfortunately, I mainly do B&W, and use the zone system to expose for specific details and vary development times to compensate for contrast. In the little colour slides I do, the meter has been pretty good, taking into account that I might have to open up a stop or two to make sure that the highlights come out bright, if the scene is a little dull. I find that it is easier to do slides, because the film generally has more latitude and you can't monkey with development times. I don't process my own colour stuff. My latest foray has been into chromagenic B&W (C-41), where I also lose the ability to compensate development times to make up for highlights and contrast when I expose for specific detail. I hope the better grain possibilities make up for less control. My first rolls are almost exposed and ready for the big test.
