View Full Version : Low light, low distortion 4 MP camera?

08-20-2004, 04:16 PM
I'm looking for a digital camera to fulfill a specific laboratory need. We want to take images of a phosphur screen illuminated by an electron beam. We are currently using film and converting it into digital images.

The highest priorities are:

1) Manual shutter control (up to several seconds).

2) Low dark noise (probably some kind of dark current frame corrector).

3) Very low barrel or pin cushion distortion.

Features like zoom or a fancy adjustable display are not important. Manual focus would be nice. 2 MP will probably be fine, but 4 MP wouldn't hurt.

A friend has a Canon Powershot A60 that sort of works but has a lot of barrel distortion.

I have a Panasonic Lumix FZ-1 but it lacks the manual shutter speed we need. I'm considering an FZ-10 but they are pretty expensive and the 12x zoom is not needed.

I can probably do tests of barrel distortion at a CameraWorld, but I'd like to have an idea of what to test.

Any help is appreciated!
