Hey folks, I created a free reach calculator, no strings attached:
https://jpolak.org/utilities/reach/calc.html
What it does is calculate an equivalent set of focal lengths on a pre-defined set of sensors, each of which gives you the same number of pixels on your target. It’s NOT a field of view calculator, but depends on pixel density.
It doesn’t validate for numerical inputs so make sure you just put valid numbers in it.
Just programmed it for fun. Any comments welcome.
