I beg to differ. *You* can remain ignorant on the subject if you wish... DOF changes, but fstops/apertures are the same regardless of sensor size. It's simple physics — the amount of light passing through the lens.

Exactly physics, the 50mm F2.8 has a larger front element than the smaller 25mm F2.8 front element now are you going to try and convince me that the same amount of light will pass thru the smaller 25mm F2.8 as a 50mm F2.8. Has the 25mm F2.8 have some special power that allows it to suck more light thru its smaller opening.

It's been that way since 8x10 view cameras vs. 4x5 vs. 35mm... did anyone used to say, "yeah, but f5.6 is REALLY f8 if you move to medium format, dude..."

FF fanboys love to use this fstop equivalence BS. It probably takes away some of the sting of having spent $4,000 bucks on a lens.

The Camera is only a tool, photography is deciding how to use it.
The hardest part about capturing wildlife is not the photographing portion; it’s getting them to sign a model release
