Yeah, the D50 from what I understand, is approximately equivalent to the Canon Rebel XS. When I bought my XS about a year and a half ago, it was Canon's cheapest interchangeable lens DSLR. Now, I don't even see it advertised anymore, although I think it's still available. I've been a pretty hard-core photographer for almost 30 years, but the XS was all I could afford at the time, and ironically, even though it's Canon's cheapest, that's the most money I've ever spent on a camera -- and I've probably owned over a hundred. Still, it's been a decent photographic tool, even if it's an entry level one, and does most everything I need. So I can't complain.
I'd really like to get a 5D II one day, but I have no idea where I'll come up with the cash for one (don't believe in credit cards). Heh. A 5D II costs more than I've ever spent on a motorcycle!
Which reminds me. Maybe a worthwhile thread to start besides "Show us your XS" will be one on outstanding motorcycle-related photography. Sadly, I would probably have few, if any, images to offer in that regard right now, but perhaps soon.
