Hello,

there are now Adapters for EF-lenses available with built-in aperture:

http://www.43rumors.com/new-canon-eos-to...e-control/



So, a question for the optics-specialists:

As I assume, the position of the aperture blades in the lens ist important for the IQ.

What do you think?

Is the IQ degraded if you close this aperture within the adapter?



Thanks

Lars

I wonder how long it will take before someone design a chip to translate NEW & M4/3 commands to Canon aperture commands
