  Specs   Functioning    Compared   Recommendations

This Canon 50mm f/one.2L is the sharpest 50mm lens I’ve ever used at apertures faster than f/ane.4.

Just grab the ring at any time for instant manual focus override.

It’s merely almost the same equally its larger, older blood brother, the Canon EF 50mm f/1.0 L, with this f/ane.two lens having a niggling more than overall dissimilarity and sharper in the corners wide open.

If you need sharpness at broad apertures you tin can’t go with the smaller and much less expensive 50mm f/ane.four USM, this 50 one.ii delivers. Once you’re shooting at normal apertures like f/4, this one.2 lens is the same as the 50/1.8 II, either of which are a lilliputian bit sharper than the ane.4 USM.

Canon 50mm f/1.2

Note how the prism of the tiny XTi has been designed to adjust even these crazy professional lenses without obstruction.

Good News:

i.) Best super-speed 50mm lens I’ve ever used, with no veiling haze like conventional fast 50mm lenses wide open up.

2.) Smaller, less expensive and faster autofocus than the huge 50mm f/1.0 L and much faster autofocus than the 85mm f/i.2L Two.

3.) Great, modern ergonomics.

Bad News:

i.) Expensive.

2.) The $125 50/i.viii 2 is just every bit abrupt if you’re non shooting at large apertures.

Canon calls this the Canon Lens EF 50mm f/ane.2 L USM.

Electronic Focus. All modern Canon lenses focus with a motor in the lens.

Expensive equally L. No verbal technical meaning other than this existence Canon’due south lingo for lenses with extra immovability and weather sealing. L lenses work on all cameras including motion-picture show and total-frame digital. Canon puts a red band around the front end of Fifty lenses.

Ultra-Sonic Motor: The focus motor operates silently.

Focal Length


On an APS-C camera it gives an angle of view similar to what an 81mm lens would requite on a 35mm film camera. Run into also Crop Gene.

Used on a one.3x camera it gives an angle of view similar to what a 63mm lens would give on a 35mm movie camera.


8 elements, 6 groups, including one glass molded (GMo) aspherical element.

The lens has a floating blueprint with which the lens adjusts itself to optimize correction every bit it’s focused.

Canon 50mm f/1.2 MTF

Canon 50mm f/1.2 MTF.

Canon rates it as decent; but not every bit good as the insanely adept 85mm f/1.2L II. My tests confirm this; this 50mm gets softer in the corners wide open (total frame) and the 85mm f/i.2L Two doesn’t.

What Moves

The front and rear groups move within the barrel. The butt itself and filter threads don’t motion.

Focus Distance Scale



AF speed is fast. Information technology focuses as fast as my optics. This is much faster than the 85mm f/ane.2L Two. and faster than the 50mm f/1.0 L.

Audio and Noise

Transmission Focus:
Plastic on plastic.

Most the same.

Ease of Manual Focusing

Excellent: simply grab the ring at any time.

For best results, get a special focus screen optimized for fast lenses. You can’t see focus too with the standard focus screens, which are designed for f/2.8 and slower lenses.


utofocus Accuracy and Consistency

Sharp results at f/1.2 need perfect focus accuracy. Depth of field is so thin at f/one.2 that whatever subject, other than a flat exam chart, will more often than not exist out of focus.

If your camera has it, yous may need to adjust AF Fine Tuning for perfect results at f/1.ii.

If your photographic camera lacks AF Fine Tuning, it’s non likely that any given sample of lens volition give perfect results on your camera at f/1.ii. No worries, if shot with an older camera, acquire how or where to focus for perfect results with your lens.

My 5D Mark Three gives consistently cracking results at f/1.2.

On my original 5D in 2007, I got some frames that were way out of focus, even though the AF system assured me I was AOK. Picket for this if y’all’re shooting this on an older camera.

For perfect results every time at every aperture, focus with Live View, just you probably won’t need it.

Manual Focus

Manual focus is typical. It takes 130° to turn from infinity to i.5 feet/0.45 meters (the 50/1.0 L takes 280° to get to 2 feet/0.6 meters).

Focus Breathing

Breathing is a movie term which refers to what happens equally you pull (change) focus from near to far.

The image from the Canon 50mm f/1.2L gets bigger every bit focused closer.


back to Functioning or dorsum to Introduction.

Bokeh is off-white. Isolation is excellent at f/ane.2, but isolation is a different issue than bokeh.

Bokeh, the quality of defocused blur circles, is mediocre. The blurs circles get lighter along their circumferii at f/1.ii.

The bokeh of the 50mm f/ane.0 is actually very, very like.

The 85mm f/1.2L II is much smoother.

Canon 50mm f/1.2

Full image at f/1.ii and ten feet (3m), one.6x Catechism XTi.

Annotation how the blur circles await like trivial rolled condoms, not flat circles. Normal, neutral bokeh would yield ordinary circles, and the elusive perfect bokeh (I’ve never seen it) would return these circles as Gaussian distributions.

Lateral Color Fringes


back to Performance or back to Introduction.

There aren’t any lateral color fringes, and so long as y’all’re in perfect focus. If you’re not in perfect focus, spherochromatism will give other color fringes — just that’s a different aberration.

If you lot’re non in perfect focus, y’all’ll see some secondary axial chromatic aberration (magenta) if you’re focused in front of your subject. My autofocus arrangement focused a tiny bit besides close, and this is what I go using AF at f/1.2:

Canon 50mm f/1.2

Unsharpened crop from higher up at 100%, autofocus, my 5D.

Same affair at f/1.ii, except in proper focus.

To become this in focus I pointed my AF sensor at the bushes a few feet backside the gazebo. My 5D has a consistent focus kickoff, which is unlike from the shots where the AF organisation missed entirely.
