Re: Corner sharpness: Four Thirds vs 35mm (bandwidth warning)

Without tesing them at the same aperture setting the test is a
complete waste of time.

Couldn't disagree more. Testing them at the same f-stop would be a complete waste of time, since these are two completely different systems. DOF would be different, noise or shutter speed would be different.

I think Amin did a great job here. 2 stops smaller aperture for the FF system, 2 stops higher ISO for the FF system is the only way to compare equivalent setups.

Lens choice should perhaps have been different though. Tamron 28-75 2.8 would be my choice for the Canon system.
