Introduction
Canon takes pride in offering the biggest variety of ultra-large aperture lenses in the
(DSLR-)industry starting at EF 24mm f/1.4 USM L all the way up to the EF 200mm f/2 USM L IS.
The EF 24mm f/1.4 USM L was probably the "worst" of these lenses and 13 years after its initial
release the update is finally here - the ... guess what ... Canon EF 24mm f/1.4 USM L II.
Typical for L (=professional) grade lenses the lens is beautifully crafted based on a weather-sealed
metal body. The very broad, rubberized focus ring has a smooth and slightly damped action.
The size of the lens remains constants regardless of the focus setting. A deep petal-type hood is
included.
Thanks to the usual ring-type USM drive the focusing speed is very fast and near silent.
Full-time manual focusing is, of course, possible in one-shot AF mode. The lens has a rear
focusing system so the front element does not rotate.
Here's a comparison between the old mk I and the reviewed mk II lens:
