Originally posted by Class A Not only are you comparing with different noise reduction applied (in-camera), you also show the K-3 image at higher magnification.
You appear to have cropped out the same sized pixel area for both cameras, which shows pixels at the same size, whereas the K-3 pixels should be smaller by a factor of 2/3 to provide a fair comparison.
There is no question that a smaller pixel (from the K-3) will look worse than a larger pixel (from the K-5) when both are shown at the same size. The question is whether the K-3's larger amount of pixels can compensate the higher per-pixel-noise, accordingly.
Yes, please turn of all in-camera noise reduction.
Please also leave the EXIF data intact. In one comparison you show two crops, one from the K-5 and one from the K-3, but there is no difference in magnification this time. How did you scale down the K-3 image? If you leave the EXIF data intact, we can make sure that no errors happen (things like that happen, as your first post demonstrates).
Making fair comparisons isn't as easy as it sounds. The results from Tjompen1968 look like what I'd expect and are in line with what DxOMark results.
Here's why I did things the way I did.
Essentially, I've decided the 16K images are more than enough for what I do. What I want is more magnification from the K-3 and more ability to crop, for BiFs and moving animals.
So essentially, most of the time I only want 16mb of my 24 mb k-3, image, so the test id designed is to find out what I need to know.
So this is the test to find out what I need to know. Now if you have different tests, that you need, for the stuff you do, I might be able to help you out I might not. But please don't expect me to spend hours of my time to do tests you've devised for someone else's needs.
If for your needs, you need a different things done a different way... hop to it.
I post my stuff, not because I'm out to do the tests everyone wants, I do the tests that test the things I want to know, and post results so that others with a similar mind set don't have to repeat my work.
Thanks for understanding.
If I ran every test I'd like to do the way I'd want to do them, I'd be here for years. I have to focus on what's important. This test was exactly what I wanted. IN terms of testing with NR off, if I'm a little unclear as to why turning NR off would make the noise better. I'm curious, but what I'm hoping for is that it doesn't make any difference. With the K-3, I shoot one card for jpeg and one card for RAW, so I'd like those NR settings on for the jpegs, and off for the raw. So that's why I'm going to test the whole NR thing. I'm still hoping NR doesn't affect RAW to any noticeable degree. The jpeg card goes to my iPad, for image review in the field., and will eventually be my flu card slot.
