Big pixels or Little pixles?

[arash_hazeghi]

To be clear, the Moon as a test target is a very tough subject. There is color in the Moon, and there is a complete range of contrast, from very high (the craters on the terminator, to very low (sunlit areas away from the terminator). Note the subtle color variations in the basalt flows in the maria (the dark areas on the Moon). Note too, how those color differences are lost as ISO increases.




But this is no different than my test. Sensor size is irrelevant and the only/main factor changing here is pixel size (and the corresponding small variations in the different generations of the sensors). So for all practical purposes, the sensors could be exactly the same size here. That is why I only specified pixel size in the legends.

moon is a tough subject for sure and you have excelled in photographing it and getting to the bottom of what is best, it is just different compared to birds :)

I agree since your test was FL limited it doesn't matter how big or small the senor was, the same image was projected on all three sensors and it shows the effect of pixel size only.

My comment was more in terms "general" comparison between small and large sensors because one of the merits of the large sensor in non FL-limited situations is that you can get closer to your subject and get great IQ-your test is great for the subject and condition described.

I think the best is a large sensor with a pixel pitch that falls in the sweet spot of current generation technology ;)
