I dont know if I mentioned it before: the camera's owners were helping during the tests in order to minimize possible errors.
As you may imagine this review/comparison has generated controversy upon spanish Nikon and Pentax users (Canon users didnt say a word as far as I know). Some guys on the Spanish Nikon Forum discredited the guys who made the tests and the whole thing became a mess.
The testers admitted that there was a problem ONLY on the ISO 100 test, and thats why they posted images from Nikon and Canon with different speed and aperture, even so they are not completely satisfied with the final test.
I know personally the spanish pentax forum moderator and there is no need to say that he is a wonderful guy, nice and kind and it was never his intention to make a biased test, he did it honestly and as good as he could, always with the help of Nikon and Canon users, as I said before.
So, in order to prove their honesty and objectivity, there is going to be a second test in a few days to come. They learned from the first test so some conditions/rules will be changed and some other will be the same. Here is the complete list:
- Exposition will be determined by a exposimeter (is this word correct in english?
) and it will be applied to all cameras.
- A much better tripod will be used.
- Shots will be done in RAW without noise reduction.
- The same software will be used on all the photos developing, same parameters, camera's users will be attending the review, jpeg output, max quality, sRGB.
- Same lens again for all cameras: Sigma 105 f2.8 Macro.
- Shots at ISO 100, 200, 400, 800, 1600, 3200 and 6400.
- Front/back focus tests will be done in advance.
I will keep you informed. Thanks,
Alex.
