[QUOTE="WayneF, post: 329797, member: 12496"] Yes, that was my original response. f/8 is f/8, 1/100 second is 1/100 second, and ISO 100 is ISO 100. DX or FX sensor does not affect those parameters. The general answer might also include "nor camera shake on a tripod", but the DX image is in fact smaller, and has to be enlarged more, which would slightly magnify the blur, if any. Yes, because FX is a larger sensor, which if assuming similar megapixel counts, then generally implying more space for larger pixel buckets to collect photons, which is a higher signal to noise ratio, which is less noise. But it depends on how many actual pixels are present in the area of that sensor, and so what is the actual size of the pixels? You could make a DX sensor with fewer but larger pixels than FX. I doubt it is done that way in our cameras (in the same technology era), but large pixels are extremely important to telescope astronomers (for low noise). Generally they cool their CCD sensors in use, to reduce noise. [/QUOTE]
