So I gave up on the 300mm some time back with my Phase system because it just couldn’t deliver a sharp image with the shutter bounce. The 240 is a beautiful lens, but too heavy and too expensive for the few times I actually shoot a telephoto. So I’m wondering if the 300 performs any better with the new back because of the electronic first curtain. I know if I use mirror lock up the XF is pretty quiet.
Anyone try it?
