To go with a proposed new 7D purchase, I am considering the lenses.
I figure that lenses are more enduring items than their hosts, the bodies. I may at some point upgrade to, or add, a full frame model.
There fore I am debating whether, despite there being more S series lenses, and some very enticing ones, I should begin accumulating a select two or three EF lenses.
But a question from a Canon digital slr newbie, do both series lenses work as well as each other with the 7D? If there are any differences, what are they please?
