Default Easy way to check 2 similar cameras please

I've got two Panasonic FX01's. OK it's a basic P & S, but not too bad
a one for the price I've paid.

Why 2 and why the question?

The screen on my first got broken. I bought a second off Ebay for an
acceptable price mainly because it was cheap, I'm familiar with the
camera and didn't particularly want to go through the 'analysing
what's best for me' process again. I also then went ahead and replaced
the screen on the first, partly to satisfy the challenge of being able
to do so. That was successful. So I've now got 2 identical working
cameras.

But there will be differences and before I pop of one of them back
onto Ebay, is it likely these differences will be detectable and how
easy to find ?

Thanks
Rob


First of all, the test conditions must be identical and reproducible.
I suggest using a tripod and using the time delay (10 seconds?) to trip
the shutter.
Set both cameras on Program AE, Same ISO, Fine Quality, etc.
Choose a camera-to-subject distance of about 15 feet.
As your subject, use a page from a quality magazine with several font
sizes of text and some color pictures.
Take several pictures with each camera at wide, normal and max tele
focal lengths.
When you display the images on your computer, you will find that your
eyes are exquisitely sensitive to the clarity of text.
If the text sizes are chosen correctly, you should BARELY be able to
read the words taken with the best camera. With the poorer camera, you
will be able to read much less of the text.
Compare the accuracy of the colors on both cameras vs your original
magazine page.
Bob Williams
P.S.
Make sure that the sky is clear so clouds will not drift over the sun
during the test process.

Many thanks Bob - that's the guidance I was looking for. It will be
interesting to see if there is much difference.

As for the rest of you (less Grimly C ) - I knew that this NG was
suffering badly from spammers, but I hadn't realised it was also been
taken over in parts by idiots.

Firstly I said that I'd been successful in replacing the screen, try
reading and understanding Ofnuts, and in terms of deceptive practice,
what is the difference between replacing a screen in a camera and some
broken part in a car you sell ?
Rob


The fact that the camera was repaired, and not even by a
professional, should not be concealed. It affects the value
of the camera, which is probably why you don't want it
known. As for a car, turning back the odometer when you are
selling a car is illegal in most states.

How was my response "idiotic?"
