Originally posted by kphillippo I'm currently trying to decide between the K-50 and the K-3, after doing research and finally narrowing down to these two. Part of me thinks the K-3 isn't necessary for the level of photography I'll be starting at. However, if spending the extra $600-ish is worth it, I would be willing to consider K-3. Another concern of mine is the lens; is the stock lens okay or should I consider buying the body and lens separately? From what I've read, I can always upgrade my lens down the road as my photo skills improve.
I recommend buying the best camera body you think is reasonably priced. While the K-3 will many features you don't yet understand, when you are ready to use them, they will be there. It is a camera you can grow into. It is not inherently harder to use than the K-50, just with more advanced stuff that you can ignore for a while. The K-50, however, is a camera that you can advance beyond if you really start getting into things. If your plan is to keep it in full auto mode forever, then you won't see a difference. But if you want to experiment with things like high ISO, difficult low-light shots, etc., then the K-3 will provide you with the equipment to do those things.
The key to selecting a camera is not the level of photography you are at. It is the level of photography you aspire to reach.
For starters, the kit lens will serve you well, but as you get better and figure out the limitations of the kit lens and what you want to accomplish, then purchasing new lenses will make sense. You can, of course, begin with better lenses, but unless you really know what you want to do from the beginning, it's unlikely you'll get the right one. Lenses have strong resale value so it's not like throwing money away when you do purchase the wrong lens, but the kit lens costs the least and functions satisfactorily. It will let you learn what lenses do well and poorly and teach you how to select your perfect lens.
