Pixel size/focal length
Hi,
I'm reading up on imaging theory, and was wondering about the optimal relationship between pixel size and focal length. I've come across the "pixel size x 5 = target focal length" equation, and found a calculator that gives me some numbers.
As I ponder different options, reading too much and getting lost in detail, my goal has become to be able to image at the native f-15 of my 180Mak.
With this in mind, I've attached the calculations for two different sensors. Disregarding field size and considering only pixel-size-to-f-ratio, does one look markedly more suited than the other, or is it really just splitting hairs?
Cheers
Stephen
