Hey everyone,
I'm just trying to wrap my head around this. I recently picked up a reversal ring which I'll be using along with a nifty fifty and some extension tubes for macro purposes. I've been wondering, and I'm quite sure my intuitions are correct, but doesn't the aperture retain its same function when reversed?
As in if I do the DOF Preview trick to set my aperture (before reverse mounting the lens) to say f/8, would it not increase my DOF over its normal wide-open reversed setting (f/1.8)? I mean, the aperture is still limiting the light entering the sensor, so thats all that should matter in terms of DOF, but I just want to make sure.
Am I correct in my suspicions that regardless of the lens being reversed, if it looks and smells like an f/stop, it still acts like an f/stop?
Thanks
Toga
