Solid build quality

The lens is good overall, good focus speed and in low light conditions, good build quality

The quality of this lens is absolutely amazing

At f/1.4, it is of course extremely fast, lets a lot of light in for when I shoot past 7pm and the build quality of this is superb

Considering how sharp the 24-70GM is wide open, and how this needs to be stopped down to f/2 to get a prime quality sharp image, I see no need to add this to my gear bag

AF works, although not quite as fast as I would hope for
