Here's the deal: In my younger days I did a lot of 35mm photography, including my own developing, etc. But then I had children and my life became pretty busy and focused on other things. Kids are grown and have kids of their own now and I would like to take my photography a little more seriously once again. Several years ago I purchased a Nikon D70 and have really enjoyed it. To be honest, the main thing that I use it for is to photograph my students and use the photos and video I shoot to create DVDs for them. When I am using the camera for myself, I am usually taking wildlife, nature and grandchildren photos. So my problem is that I am pretty sure I want to get a newer Nikon. My husband has actually offered to buy me a new Nikon D700, but the price puts me off a little. I live in the mountains where we have elk, deer, etc. that often visit and I want to take really good photos, but I am afraid the D700 might be overkill. I love the idea of full frame, but something keeps nagging at me that I would probably be just as well off with a D300. I actually went as far to buy the D90, but returned it unopened. Is DX going to stay around for a long time or will everything eventually go FX? So many questions, plus the fact that I would simply feel guilty for letting him buy me such an expensive camera, especially if I never use it to full potential. I would greatly appreciate any advice, opinions, ideas that could help me make what has become a very difficult decision. Thanks in advance.
