First, I am a Canon guy. I own over 10k$ in Canon gear and I think I take good pictures.
I think this entitle me to say that a lot of the previous poster dont know much about what they are talking about. Sony Alpha bodies are getting very good reviews and have some incredible features, such as the in body IS or eye scan to start the camera - focus point.
Also, a lot of attention is on Nikon these days but Sony is the company that is moving forward the fastest these days. Because they are in a green field they can be very creative and that is what they are doing. If I was to start from scratch with 10k$, I would give a serious look at Sony.
Finaly, the look of their lenses is straight from the future! ;-)
I cant provide you with a straight answer because there are none. Both system are good, actually every camera manufacturer has great entry level bodies these days. You just have to pick the system that you like the most.
My only real suggestion is to get a 50mm1.8 lens. What ever the system you get, you will need one ;-)
So you own 10K in gear, shoot Canon, point out that you're an authoritative source on Canon and none of us know what we're talking about, only for your post to talk up Sony products?
Then in the end your advice is to suggest buying a prime lens, something which other people on this forum already suggest anyway and the only difference is we haven't spent 10K on gear and become arrogant in order to figure this out?
