High Quality Repro

High Quality Repro
several dslr questions Q1) how large of a high quality image can i print w 12mp @ 100 iso and a fixed lens?

2) Can I use my sb 900 flash on a canon dslr, if i use it in auto mode and manually set the f-stop and and iso?

3) will a 35mm lens for a non full-framed dslr like a d90 or t2i be equivalent to a 50mm lens for a 35mm film camera, in terms of distortion? i know that there is a 1.5 or 1.6 ratio in regard to calculations how zoomed in your lens will be, based on the size of the sensor. However someone told me that even though a 35mm lens on a dslr is almost equivalent in zoom it will still cause distortion on the dslr. I also heard that this is untrue. I want zero distortion because I want to do accurate art reproduction photos.

4) I'm considering getting a t2i, 7d, or a850 for more resolution, in regard to the art repros. Any recommendations? I already have a d90, which i might use for the art repros, might sell it, or might hotrod it.

Your D90 can provide an image file that is 4,288 x 2,848 pixels that will provide the following:

14.293 by 9.493 inches at 300dpi
and
23.822 by 15.822 inches at 180dpi

If you stay at least at 180dpi then that is about your range, also shoot RAW files. The next big step if you are wanting more quality is to get a full frame (35mm film size) sensor camera or a medium format sensor camera (see first link below) like a Phase One camera, Hasselblad, or Mamiya. I would not leap to anymore DSLR cameras unless you are going to a bigger sensor.

If it is dedicated for Nikons then there will be limits but I really do not know since I am a rare flash user. Be certain of these sort of details so you know the full impact of switching brands.

Yes, a 35mm focal length lens on a Nikon DX DSLR (like your D90) is equal to a 52.5mm lens.

Go to a bigger sensor, your D90 is an excellent camera use it until you figure out what option. The D700 is great and there is rumor if it getting replaced with something better.

Hope this helps.
