I recently bought a Nikon D5100 that I absolutely love. So far, so good! The only issue that I have, and it's a personal one, is that regardless of how focused a picture looks in the eye piece, they sometimes come out blurry. I wear glasses, and I'm positive that's where the issue is coming from. It's happening with either lens I'm using...the 18-55MM and the 55-200MM. I've read that there's an eyepiece attachment that magnifies only the center of the view finder...a DG-2. I'm curious if this would work for me? Is there something else I can do? If I use the live view, they're coming out just fine, because I can see the image larger and focus it better. Thanks in advance for ANY advice!
