Originally posted by richard balonglong I agree with you, 24mp is 24mp, either APS-C or FF, they both have a 6000 x 4000 resolution. But a 24mp FF sensor (versus the 24mp APS-C) still has an overall advantages for the photographer when it comes to image quality and flexibility due to its larger pixel size.
IN good light and low ISO, I doubt that's true. APS-c definitely loses it's dynamic range faster as a rule, but at 100 ISO a K-5 has more dynamic range than any Canon, at least on paper. Although I have to admit, when you're looking at the numbers there are some pretty interesting anomalies.
So did you actually compare prints.. or do you have some examples? This is great stuff if you have examples. I (and many others) hate relying on other's judgement, in that we all have different values.
In my real world example if I was to provide one, my K-5 DA* 60-250 prints look practically identical to my buddy's Canon FF plus EF 200mm f/2.8L prints. I doubt you could tell the difference. This was on a day when there was great light, the subject wasn't moving and we were shooting at low ISO. I'n not going to say you can't come up with a situation where an 35mm sensor won't outperform an APS_c, it's has a number of advantages that have been endlessly discussed. However, that doesn't mean there aren't a lot of situations where the APS-c performs as well or better. The superiority of larger sensors for better images at high ISO is pretty much established. As is more magnification for APS-c at low ISO, enabling the use of shorter lighter lenses.
Just saying, if you select a specific situation, you can make any format look good. They all have their strong points.
But it's because you choose to make that format look good, not because you couldn't have made the other format look good by emphasizing it's strengths, should you have chosen to go that way.
