I just bought a Nikon D700 and when examining photos with a loupe at 100%, I noticed that the details were a bit soft. That brings me to the question, Can I get 20" x 30" prints at an ISO of 200? I use the following lenses with a tripod: 17-35 mmf2.8; 28-70 mm f2.8 and the 80-200 mmf2.8 lenses. Iwould appreciate any feed back. Thank you.
