I am surprised that everybody is mad about the DOF part, but nobody is
surprised by this nonsense:
"Here is a fun fact: the lens set to f/2 on every sensor will result in
the same shutter speed for the same exposure. This is because the sensors
have different signal multipliers, meaning that 100 ISO is not really 100
- it is actually multiplied, and you simply don't see that."
While all the equivalence discussion is such a mess (it can be confusing),
and this guys is totally confused, in this statemenet, he defies the laws
of optics, including the definition of aperture and it's relation to the
amount of light coming through the lens.
James: the simple response is: do not read what's written on
the public restroom's walls.

Edited quote:
A 50mm F2 lens on full frame is as expected a 50mm F2. On a 1.5 crop
sensor, it is a 75mm F3.
