B&H offered a single-shot promo code to people who had purchased an Adobe product from them in the past. I jumped at the chance and now have and received CS6 on Thursday. $400 savings are not to be sniffed at

Given the investment you're looking to put in to Zeiss glass you'd be well served to subscribe to DigiLloyd. He has extensive reviews of every lens you've discussed.
so are you saying that say you are shooting a concert in very low light with a 50 f1.4Not quite - but let's assume the f/1.4 lens collects light like a f/1.7 lens, then you would get the same effect using a f/1.7 lens and boosting the ISO by 1/3 EV. Of course, since a stopped down fast lens almost always outperforms a wide open slow one, you would probably sacrifice vignetting and perhaps image quality.
@ f1.4 3200 iso
you would be better off shooting at say f2.2 @iso 8000
or f2.8 @iso 12800
because from an iso noise POV this is what is happening anyway?
Many thanks - very useful info knowing that v fast lens buys shallow DOF and (perhaps) better bg blur and bokehActually no - the point is that light from the perifery of the lens does not make it to the active part of the sensor and so it cannot contribute to the image or shallow DoF. Mounted on a 5D2, a 50L can barely perform like a 50/1.6 (albeit a very good one.)
It depends on the camera. The 7D is worst but it affects all digital cameras (not just Canon.)
So this only applies to the very fast lens? Why doesn't the change in ISO register?
I wonder where this starts happening? f/2, f/4?
