Circular fisheye on full frame. And I just bought the mark I of the 300mm 2,8L IS like a month ago...>.< But Im really interested in the Extenders. Well their always affordable. Since the 2.0x TC II focuses really slow when attached, I wonder how the mark III will perform in AF speed (not just Center AF point). Im also quite interested in that fisheye The new 300mm and 400mm gets a new feature for the front element; Anti-Smearing glass (Against water and oil).
