Have a Canon 5D classic with the filter replaced with a badder acf to give improved Ha sens. auto focus & WB work are un-affected by this mod. I am the 2nd owner but am unsure of the shutter count (i was told it was low when i purchased it) serial no. is from a later model. with battery/charger/discs/manual
Maybe it is, I've been looking at this as well, the lure of full-frame.
I believe (could be wrong of course) that Gerd now has the "XL" clip ins, so full frame. http://www.astronomik.com/en/clip-fi...ollformat.html
