Having heard/read so much about the 400D subexposure problems, I decided to do a little test. Borrowed one from my friend(who was allways moaning about the constant subexposure) and did a shootout with my 20 & 30D´s.
The method followed was pretty simple: Shoot indoor, controlled lightning, shot a grey card with 3 lenses: Efs 17-85, Ef 80 1.8 and 70-200 F4 Is. Tripod mounted I first found the "correct exposure" with the 30D and then repeated the shot with the 20D and 400D with the same lens, dialing in the same aperture and speed than with the 30D.
In short, exposures for the 20 & 30D are identicall. The 400D consistently underexposed by 2/3 to 1 whole stop!! The lens with wich it underexposed the most was the 17-85 (nearly a full stop) judging the histograms.
I have been considering a 400D as a small "carry everywhere" body with a prime or two. I have read somewhere that the underexposure problem only afected some cameras. I would like to know other peoples findings and if this is an issue with the model or just SOME cameras.
Any input will be most appreciated.
Kind regards, Erik.
