Hello all,

I'm about to go look at a 20D with 30,000 clicks on it. Possibly going to purchase it to fill the void that my T1i left after I sent her in for a check up.

What, if anything, should I be on the look out for? I will get the chance to test it out before I give it the yay or nay.

Thanks in advance for any advise.

Chris

-body wear and tear
-all the buttons
-Auto focus check for accuracy and speed
-hair line cracks/scratches on screen
-dead pixel check
-sharpness
-dust spots check (shoot the sky at a small aperture and OOF)
-onboard flash check
-burst mode check
-put it in sensor clean mode and look at the sensor

A few tests shots at a range of shutter speeds down the 1/8000s or whatever the fastest is (check the shutter isn't sticking).

The above is otherwise fairly thorough, although other than a real check check inside I wouldn't bother looking at the sensor if the photos seem fine. Also check there is no signs of impact or bending around the mount and that the contacts look fine.

Note that many seem to have trouble popping up the inboard flash and might need a little wiggle unless it gets used regularly (camera errors and needs to be turned off + back on). This seems very common with them.

The screen will seem tiny to you coming from a 500D, but the ergonomics in comparison are awesome.

The dust spot check and body wear and tear are a bit superfluous...


Unless you download the pictures into a computer and look at them on a large screen, you're not going to be able to tell if there's dust on the sensor. The screen on the 20D is just too small. Besides, dust can get back onto the sensor quickly, even if the camera has just been cleaned.

If the camera has been used at all, it's going to have some body wear. There's no way to avoid it. Mine has a bunch of wear on it around the back buttons, but functions like the day it came out of the box.

The important thing is to check all the functions of the camera in all modes and at all shutter speeds and apertures. Take one or two of your favorite lenses along and try them on the camera.

Thanks guys! The seller was quite pleasant to deal with. I got a steal of a deal, I think?
