This new 50mm 1.2 is simply amazing! Considerable improvements compared to EF version: sharper, focuses faster and extremely accurately with the R camera body (basically, you can get f/1.2 shots all day long), and better control of fringing. This lens still has its own character; it has not gotten too "clinical" as newer lenses seem to be getting lately. A key ability of f/1.2 lenses are their ability to create separation of subject from background (or a 3-D effect), and this lens delivers here extremely well! Out-of-focus areas gently transition into dreamy blur and lift the subject off of background. Naturally, this lens takes in tons of light! With my RP body, I can seriously take shots in near total darkness! You can get very close to subjects, giving it pseudo-macro abilities with a good crop. Additionally, I like the focus limiter and control ring, which make for some very nice enhancements and additional controls. It is large, a tiny bit bigger than an 85 1.4, but feels nicely balanced.
This lens hasn't left my camera body since purchasing, and I imagine it won't for quite some time. I am very pleased with this amazing lens, and think it's worth every penny! All sample shots in this review shot a f/1.2.

Big, heavy, expensive, but that background blur makes it all worth it!

One of the original Canon RF lenses that still performs flawlessly. A favorite of my kit.

Let's just hit the salient point right off the bat, this lens is optically stunning. The rendering and bokeh are great, the sharpness even wide open is phenomenal. It's truly a wonderful lens.

It does have some issues with chromatic aberration wide open, and can suffer contract issues shooting wide open against bright light, but at 1.2 that shouldn't be surprising.

The detail you can get with this lens is amazing!

If you're looking for an amazing versatile lens, the RF 50mm 1.2 will be exactly what you're looking for. Whether you're looking to shoot videos or stills, this lens can get the job done. I have multiple RF lenses but you cannot beat the focal length of the 50. If you're on the fence, make the jump. This lens has basically replaced all other lenses in my bag. Great for portraits, product photography, & so much more. The autofocus is insanely quick, making it super easy to capture objects in motion. The build quality of this lens is impeccable, once you just hold it in your hands you'll have absolutely no buyers remorse. Feels like you're holding a precious gem.... But useful of course. Quite hesitating, this is the lens you need.

Fast delivery, high quality

What a great match with the EOS R, which I purchased just so I could start using this lens. AMAZING for dynamic portraits, great for kids.

I waited and waited for Canon to release an update to the ef 50mm 1.2L, which I saw as too soft wide open, and problematic with its focus shift issues. (I like getting in very close, right where focus-shift would be at its worst.) When Canon finally did come out with a 50mm dream lens, it was on the EOS R. I mulled things over for a year, then finally went for it. So happy I did. The IQ and bokeh are great, and the EOS R's Servo AF makes nailing focus easy, even at f/1.2. No hint of focus shift here at all in the ranges of f/1.8-2.8.

Just crazy about this lens!

I am a prime lens shooter, I almost never use zoom lenses. And the 50mm focal length happens to be my favorite. That being said, this lens is the best I have ever used. And I am a bit of a lens snob. I've used over 50 different lenses over the years, including Zeiss. This Canon lens is just the best.

excellent lens, greats
