I am choosing a camera and lens.
I want to buy a Canon EOS 650D, as this camera seems to be a good point of entry into the world of SLR.
My question is in the following:
The EOS 650D has a cropped sensor, so as I understand if I use Canon 50mm f/1.8 lens, the behavior will be quite different on a smaller sensor in comparison to full-frame sensor.
What is the relation between cameras sensor size and lens focal length?
