I got this lens some years after acquiring the EF version with the hope that I can use it without the fear of damaging the AF function and focusing system since it's focused by wire. If the lens stop working, I can't even use manual focus. On Canon DSLR, while the EF version can easily misses the focus point since it's very shallow and it can change during the shooting process, I need to do manual focus to ensure the critical sharpness and it's not that pleasure to do manual focus on the EF lens.
This FD lens is basically the same, with just a bit different in the outfit. It comes with a trunk and it even looks cooler than the one for the EF lens. I highly recommend using this FD lens on a mirrorless system, especially Sony A7. With some A7 camera, you can even autofocus the lens using Techart Pro adapter, as long as you have a tripod to support the lens from below.
The sharpness of this lens may be less than some high quality modern lenses but still exceed my need that a cropped photo is still enough for printing. I also didn't find any considerable trace of chromatic aberration even at f/1.8. However, this lens suffers from flare if a strong light gets into the lens view so it's recommend to use the hood in daylight shootings.
It's definitely the king of portrait!
