Buying a new camera? Always check the sensor for faults!

[Paul Engen]

I've now bought two cameras from Canon (Powershot A95 and Eos 350D/XT). They bouth had faults on the sensors, and turns of course out as faults in the picture. When buying a new camera, you should all check the sensor for faults. It is easy:

Put the camera in manual mode and make a shot with the lens cap on (or in a completely dark room) on all ISO values. Then you will find the dead pixels looking at the picture at a 100 % magnification. (If you do it with your computer in a dark room it's easier to spot the faults.)

You should also do several shots of a evenly coloured surface (e.g. a white smooth paper) whith different exposure times giving you everything from clear white to dark grey. Then you will find the strange coloured spots (which I have found) and the darker rings which surrounds the dead pixels.

Turn the camera back if you find the fault! If this is too late, demand that the fault is fixed!

OK cool but do you have to tell us the same thing in three seperate threads?

If you define who "us" is, I will be glad to tell you why ;-)

Ok. My thought is that not all users of this forum reads all the sections. A person owning a compact camera might not read the Eos-section. That's simple logic. But why should we spend time writing about this? This is a discussion board for photographic themes, not a forum discussing how an average person search for information concerning him/her. That belongs in a discussion where the topic is cognitive psychology. Sorry about this, and I will keep silent when reading such posts in the future.
