This lens is AMAZING! It is as sharp as my FE 55mm 1.8 when compared both at 2.8 and that is no easy task as the 55mm is one of the sharpest lenses around.rnCA is superbly controlled as well. The quality is so insanely good that even when using it as a 840mm lens (1.4x-a + 2x-a) , CA is barely noticeable at all without any corrections and sharpness remains very usable! rnHere is an image at 600mm and one at 420mm to show you how sharp it is:rn600mmrnhttps://farm6.staticflickr.com/5644/20943449929_2b8b6e098d_o.jpgrnrn400mmrnhttps://farm6.staticflickr.com/5666/20916193770_5eae47848f_o.jpgrnrn
This is a phenomenally good lens! Arguably, it's the sharpest lens in the FD series. If "10" is as good as it gets, this lens deserves 11. It should be used on a tripod, though press photographers have pretty good luck with a monopod. Image quality is just sumptuous, even with 1.4x and 2x teleconverters (for 420mm f/4 and 600mm f/5.6 conversions). FD lenses are not easily adapted to EF series cameras, but it will work with the Canon EOS "M" mirrorless digital rig, which has an APS-C size 18 MP sensor. With the M body, you get a lens equivalent to 480mm f/2.8 and razor sharp images.
