I have been reading and reading and reading on every site you could probably imagine before making a decision on what DSLR to purchase. I'm on a limited budget and planning to buy used, and while every site and every thread has lots of recommendations, I'm just feeling it's better to go ahead and ask for my specific situation and see what people think. I'm planning to go with Nikon because it's what I know and am used to - my ex has a D100 that I did all of my learning on up until this point. I no longer have access to this camera, so I'm looking to get my own. I've played with some Canons and just found them odd to work with, probably because I'm used to Nikon. My intention is to purchase a low-cost used camera, either as a body + a lower cost basic lens, or as a kit. I'd like to get something that I could "upgrade" in the future when I have more money and this first camera could become a reasonable backup camera. I am intending to get in to portrait photography - seniors, family, (eventually) wedding, etc. I want to spend some time learning on a less expensive camera, but I'd really like to be able to take it to the next step (aka bringing in income) on my first camera as well. What I've been looking at and my thoughts so far: Nikon D50 - inexpensive used, but lower resolution. Lots of compatible lenses because of internal focus motor. Nikon D40 - also inexpensive used and lower resolution. Seems to be about the same cost as D50, but less lens compatibility. Nikon D5100 - more expensive as it's a newer camera, but higher resolution and many neat features. Less lens compatibility, and not sure if the 'nifty' features are really necessary, such as live view LCD. Any thoughts to those cameras, or maybe other recommendations? My budget is $600 and under, obviously the less the better. $400 and under I could purchase now, $600 will require two more weeks and I've sort of got ants in my pants over this. Also, I feel I should point something out: This is the first board I've been comfortable posting on because the attitude here is very accepting, so I appreciate that. Many boards I've browsed seem very anti-newbie and just laugh at anyone who thinks they can start a photography business. I have been taking P&S photos for as long as I've owned a camera and have always been interested in learning everything I could soak up. I think I'm at the point in my life where it's time to take a step up and finally follow my dream.
