Special thanks to Rainer Temme for providing this lens!

Introduction

Released back in 2007 the Canon EF 50mm f/1.2 USM L is the successor of the legendary EF 50mm f/1.0 USM L - the fastest mass production SLR lens ever ... and one of the most expensive around. Surprisingly Canon decided to give up two thirds of an f-stop (f/1.0 - f/1.1 - f/1.2 - f/1.4 in case you wonder) but the good news about this is the substantially lower price tag of around 1400 €/US$ so the lens is now within the financial reach of normal mortals. Typical applications for this ultra-large aperture lens are portrait and available-light photography.

As to be expected from a Canon L grade lens the EF 50mm f/1.2 USM L has an exceptional build quality thanks to a tightly assembled combination of high quality plastics and metal parts. A sealing against dust and humidity as well as the the very smooth focus ring completes this positive impression. The lens has a constant physical length but the inner lens tube moves a little during focus operations. The front element does not rotate of course.

The ring-type USM AF drive is very fast and virtually silent. The AF accuracy was generally fine except for a hint of focus shift around f/2. Full-time manual (FTM) override in one-shot AF mode is naturally also available.
