Been spending a lot of time on here!
Just for funzies, I took a look at the FOV formula and noticed something odd, that it's non-linear. This contrasts with the user-friendly notion of "crop factor" that we're all familiar with. So, I plugged in the formula using APS-C and 35mm and compared it against the standard crop factor of 1.6.
There is some discrepency, but it mostly settles out around 50mm. However, for wide focal lengths, the discrepency is more significant, and the problem is even larger for 4/3 (upper plot):
While this doesn't matter much at longer focal lengths, it'd seem that there is a pretty large discrepency in very short focal lengths, and at under 15mm the difference is pretty significant.
Is this right?
