Do you want video capabilities? Or only stills?
For $500, you aren't going to get too much functionality in terms of a dslr body.
I couldn't disagree more, respectfully of course... :mrgreen:
I'll be the nice guy and make you a list:
Being biased...but in the interest of full disclosure, I'm switching from Pentax to Nikon in the next few weeks.
The Pentax K-x, Body+18-55mm lens kit
Pentax Pentax K-x Digital SLR with 18-55mm Zoom Lens 16302 - B&H
Pentax K-x, Body+18-55mm + 55-300mm lens kit (Best value, the 55-300 is far better than the 50-200 lens, even by kit lens standards)
Pentax K-x Digital SLR with 18-55mm and 55-300mm Zoom 15802 -
Note the Pentax does come in different colors, Blue/White/Red/Black etc.
Nikon D3000 (About as "beginner" as it gets)
Nikon D3000 SLR Digital Camera with 18-55mm VR Lens 25462 - B&H
Nikon D5000
Nikon D5000 Digital SLR Camera Kit with 18-55mm VR Lens 25454 -
Canon T1i (aka 500D)
Canon EOS Rebel T1i (500D) Digital SLR Kit w/EF-S 3818B002 - B&H
Canon T2i (aka 550D)
Canon EOS Rebel T2i Digital SLR Kit w/ EF-S/18-55 IS 4462B003 -
Sony A500
Sony DSLR-A500 12.3 MP Digital SLR Camera With DSLRA500L - B&H
I don't know enough about Olympus to make a suggestion, but the above are all of the "entry level" DSLR's with interchangeable lenses.
Obviously you're going to have to do your own homework on which would better suit you, some have in-body Image Stabilization, some have IS in the lens, some have more megapixels, some have better hi-ISO performance (low light). It's up to you to decide what you want and go from there.
The only advice I'll give, is to realize that you're not just buying a "Camera"...you're buying INTO an entire system (lenses, flashes, etc.) and more often than not, the lenses are more important when choosing a brand than the camera body is. Choose wisely, because switching systems (as I'm in the process of doing) is quite expensive.
