Thanks everyone for your help and advice. I do have more questions.
Which camera is easier to use if I plan to use autofocus 99% of the time. Right now, I have neither the time nor inclination to learn more. I keep reading about Nikon AF issues and am wondering if the other brands are easier, etc.?
Also, I have many lens questions. I'll get the dumb question out of the way first: Is there ever a time you would take pictures without a lens with a DSLR? Also, say I'm taking pictures at a birthday party indoors, what type of lens would I need. If anyone can provide me with a very basic lens lesson, it would be very helpful because I'm very confused right now. Lastly, say I wanted to capture my daughters playing soccer; lots of action, outdoors what type of lens would I want to use? Thanks to anyone who can help!! Julie
The only Nikons that have focus motor issues are the D40 and D40x.Basically, if the lens isn't equpiied w/ focus motor, then it won't AF on these cameras. They can still be used, but only in Manual focus.
I would get the Nikon D80 w/ 18-135 kit lens and 50mm1.8 prime lens. The 50mm 1.8 works great in low light and for action shots. You can use it for indoors and portraits, you just need to back up more than you would with a 30mm. Later, if you feel you need it, and really want it, you can get the 30mm 1.4 w/ HSM. That's what I would do.
FWIW, if you use a tripod in extremely low light conditions and want to take indoor family shots, the kit lens will work fine. It's just that most people don't want to lug around a tripod. You could bump up the ISO and use noise reduction software if the noise bothers you. I still don't know how to use the software and it doesn't really bother me as it's still not as noisy as a P&S. OR you could use the flash and it'll be fine. I bought the SB800 and rarely use it, but it has worked great for family portrait type photos....I found the on camera flash to be a lot better than the P&S on camera flashes, and have used them for some shots and they were okay.
I took almost all of my pictures on a recent DL trip using my 18-135 and 50mm handheld, and most all of the shots came out fine. (Exceptions were Fantasmic and Fireworks; I used a tripod for those.) I should have used a tripod in some low light, walking around the park, night shots, but was too lazy/ill to feel like lugging it around the park. I am very happy with my photos.
I recommend the D80 w/18-135 kit lens, and the 50mm prime, which will autofocus just fine on this camera. I just got the 85mm 1.8 for low light/action/portrait shots and I LOVE

IT! It autofocuses fine on the D80 and gives a little more reach than the 50mm, which is great for stage shows and sports.

Good luck!
