Philip, I'm interested to know how useable you found the Canon FD 300 L on your A7 - I currently use one on my OM-D, where the IBIS makes it useable down to quite slow shutter speeds. I am contemplating buying either an A7 or A7R, and would want to use it on that camera, but I've heard conflicting reports about shutter shock. However, these results look superb. Any advice would be useful.
Thanks, John
