i'll be viewing a 2nd hand 7D soon and i would like to seek help on what are the things to check for a 2nd hand body?
Shutter count is no problem as the seller's got a Canon Service Report.
Exterior is fine as that can be easily noticed if there's wear and tear.
LCD mustn't be scratched. Checked.
All functions must be usable. Checked.
Flash must be working. Checked.
Battery must be working, removable. Checked.
I'm more worried about the internal. Things like dust and dirt inside the sensor. Any tips on how can i check on that?
Thanks a million people. (:
