I’ve been using the D7000 for a few weeks now. I have been fairly pleased with it. Not sure about the conversion to 25p. I have mainly been shooting 1080p24 and converting to Apple Pro res and editing in FCP. I would think you could then go to 25p without any concerns, but I haven’t tried it.
I never trust the lcd anyway. I would love to have the historgram up in live view and hope they do a firmware update and give us that option. For now, I shoot manual and before going into live view I set the exposure looking thru the viewfinder. Once in live view unless the scene changers dramatically it does well. You can hit play after and see the histogram to confirm if your exposure is good. Not great, but it works.
Confirm the aperture limitation. I have manual lenses so it again doesn’t bother me. I’m even thinking of getting my lenses modified so there is no aperture “steps” between fstops.
My biggest problem has been with moire. All the dslr’s have it, some worse than others. Just have to work around it.
If you want to see some good videos shot with the D7000 go to the D7000 group on Vimeo. There are a couple that I have done as I’m learning the camera.
Let me know if you have any other questions.
