Quote: People tend to place too much significance on megapixels. The D700's larger pixel size allows it to have great dynamic range and signal to noise ratio
I'd love to see couple of sample images that would demonstrate that. The problem I have with this kind of info is, you can do the math, and theoretically you're right.. but without real world testing it's just a statement. A statement that assumes the same sensitivity to photons, if the smaller sensor actually has higher sensitivity to photons then it may in fact have less signal to noise ratio, if one is a backlit sensor, then it may have higher signal to noise ratio , filters can have an effect, the processing engines can have an effect, so ya, that's the theory. But do your science guys, without experimental evidence to back it up, no theory is worth a lot. The proof of a theory is it's supported experimentally. Until it's supported by empirical proof it's just a theory. There is just way to much stuff said on here that is theoretical. I can understand statements like the above based on the handling characteristics of the camera, how the camera feel in your hand,
I was thinking on my walk today... go down to Henry's when my tax return comes in, take some images, process them on my computer, do the pixel peeping and get it over with. It might cost me a couple days of my life but it would answer for me what the difference in IQ and let me do my own comparison. As much as everyone says you can't go by DxO ratings, they did have everyone of these cameras in their hands, and came up with a rating system that says something, even if we're not quite sure what it is it shows. If there are problems with going with DxO numbers, there is even more of a problem with going with anecdotal evidence including accommodating for differences in shooting style and subject.
To me, looking at comparative images is a first order comparison, DxO is second, anecdotal evidence is third. People say they like their D700's better than they like their K-5's, I haven't seen anyone post something different, and some who've had both say they get better images from the D700. Is that worth more or less than DxO's rating... I don't know. To me they are both evidence but not conclusive evidence, and it would take more time than I'm willing to take to explain why. jsherman post a 5 year old link testing 2 Canon products, one FF one APS-c suggesting that FF is better, marginally, very marginally. In fact from that test, my conclusion was FF was not worth the money. Other opinions may differ. Now we're talking a whole new generation of sensors and about to move to another. I just can't go with that 5 year old data, and apply it cross brand. I'm not sure how you apply a Canon FF and Canon APS-c to say a Nikon FF is better than a Pentax APS-c. To the analytical mind, that is simply not a supportable position.
