Special thanks to Johan Grandin for providing this lens!
The Canon EF 50mm f/1.2 USM L is the brand new successor of the almost legendary EF 50mm f/1.0 USM L - the
fastest mass production SLR lens ever. Surprisingly Canon decided to step down a little
regarding the max. aperture but the good news about this is the substantially lower price tag
of around 1300 €/US$ so the lens is now within the financial reach of normal mortals.
On an APS-C DSLR the field-of-view resembles
a 80mm full-frame equivalent. Regarding the ultra-large aperture the lens typical
applications are portrait and available light photography but naturally the scope is not limited
The optical construction is made of 8 elements in 6 groups inc. one aspherical elements.
The lens features 8 circular-shaped aperture blades. The filter size is 72mm.
The minimum focus distance is 0.45m resulting in a max. object magnification of 1:6.7.
Regarding its ultra-large aperture it is naturally a very fat (86x66mm) and comparatively
heavy (590g) lens.
Typical for most L grade lenses the EF 50mm f/1.2 USM L has an exceptional build quality
with a dust and moisture proof outer shell and a very smooth focus ring.
The lens has a constant physical length but the inner lens tube moves a little during focus operations.
The ring-type USM drive is very fast. The AF accuracy is just Okayish on the EOS 350D but that´s
surely more a fault of the camera´s rather mediocre AF rather than the lens. According to
Johan (the owner) the lens is spot on when used on the EOS 5D. Full-time manual (FTM) override
in one-shot AF mode is naturally also available.
