I finally did it. I bought a new camera body that will fit the lenses I have for my other camera. The Nikon D90 will suit me just fine, it has some new gadgets that the D80 doesn't have and I think I absolutely need - like a larger LCD viewing screen. I recently bought a Nikkor f/3.5 - 6.3, 18 - 200mm for a walkabout lens and I want an f/2.8- 300mm lens to take to Africa with me. The 300mm lens weighs 6.4 lbs. and I imagine I'm not going to like carrying that around, it's not a zoom lens but to take pictures of wildlife, it's essential.
TCU has adult education classes and I signed up today for their photography class that starts in May so that I can truly learn all the secrets that the D90 holds. Wish me luck.
Hope that soon I'll have fantastic photos to post.
