Buying a used Canon camera advice

[kalgra]

Another thing to consider is what lenses you currently own. If you currently have a rebel then most likely you are using mostly EFS lenses which will not work on any of Canons full frame cameras such as the 6D or any of the 5D cameras.

The 7D is an apsc camera so any EFS glass you currently own will work with the 7D.

CRAp! That I didn't know! Thank you!
Back to researching. I have canon EF 50mm 1.4 that i really like to use that was pretty pricey for me anyway that is like to keep.

That wont be a problem. EF lenses will work on either crop sensor or full frame. Its just the EFS lenses that wont work on full frame bodies. Sorry if that was confusing.
