Hmm, no. I suppose it is debatable, but not really. No.

The rest of your comments, seem true enough.

You're comparing a 2006 lens design to one of the best lenses ever built from 2018.

Re: Canon EF 50mm f/1.2 L USM lens

This looks somewhat normal but also an extreme worst-case scenario test where the black/white edges are going to make it look really bad. The older EF 50mm 1.2 and 85mm 1.2 had a lot of CA. Most of Canon's newer glass is excellent. It's a bit unfair for the 50mm to compare it to the Canon 85mm 1.4.

Unlike the EF 50/1.2L, the 85mm f/1.2LII has no CA issues.

The 85/1.2LII does have some pronounced LoCA at large apertures (just as the 85/1.4L and 50/1.2L). The RF 85/1.2 has improved on that a lot, with the Blue Spectrum Refractive optics. It's in the 35/1.4L II as well and and it's brilliant.

So much wisdom. And what about the Canon FD 50mm 1.2L?

The excessive purple and green fringing is why I sold my 85mm f1.2 II.

Yes, I wrote that because there is a difference between CA (lateral) and LoCA (longitudinal) what is also called bokeh fringing

The EF 50L suffers from both Lateral Chromatic Aberrations and Longitudinal Chromatic Aberrations. The EF 85Ls suffer from only LoCAs.
The RF versions have the BR optics that correct the LoCA very effectively.

First, thanks for everyone's help!

Although I bought Sigma 50mm f/1.4, which is much sharper and has less chromatic aberration than the Canon 50mm f/1.2, I still missed the look and feel of Canon 50mm f/1.2. So, I decided to get a different copy of Canon 50mm f/1.2. The new Canon 50mm is much better than the previous one. However, I found it is hard to get the autofocus correctly. I took about 350 photos today and there are about 10-15% missed autofocus, especially at f/1.2-1.6. I used single-point autofocus on a 5D IV all the time through the viewfinder. I don't know if I need more practice or chose the wrong settings.

Do you look at the focus points the autofocus has chosen before you take the picture ?

If you don't look what it has chosen, and are merely unhappy with what was chosen, later, when you look at the images on your computer screen, that's different.

"especially at f/1.2-1.6" ... well that is no big surprise. You are not going to be seeing any problem with autofocus at f/8.

I composite the picture first then move the focus point to the face of the person.

Re: Canon EF 50mm f/1.2 L USM lens

I did micro-adjustments today. The camera was on a tripod. I tried both viewfinder autofocus and touch screen auto-focus. Both seem fine.

What bothers me is when I take the camera out during actual use. The autofocus seems not as reliable as I expected. I took about 100 photos yesterday and about 20 pictures were not useable. I am not sure if it is my skill or there is a problem with the 50mm f/1.2 autofocus.

You do realize how thin dof is at 1.2 right? The slightest of movement handheld will throw off critical focus. This lens is also not particularly sharp wide open either if you compare it to other more recent offerings... with that being said I am happy with the resolution of this lens.
I was in a similar position as you a couple years ago with this lens and determined that close focusing at wide apertures with this lens is not the ideal use case. This lens isn’t for everyone either. It gets its fair share of criticism here in the forums but, I am on the side of the fence that this lens is like a painters tool. If you’re looking for the best resolution, best AF accuracy, and best “iq” I’d look at other 50mm offerings. Just my humble opinion.

CA and bokeh fringing can often be seen in the photos of the 50L at large apertures,
but if it is an issue depends on the user. There are a lot of satisfied users of the 50L, so for them it's clearly a small or not an issue. They like the rendering. For me, CA is an issue. So I didn't buy the 50L and went with the 50Art that has almost no CA.

Some find the noticeable bokeh fringing of the 85L an issue. I find I can live with that as it's only longitudinal and not the more known lateral CA. Others can't. You couldn't, as you sold your 85L. Which is fine of course, you know best what you want.

By 2006 few if any new lenses from major manufacturers were being designed for film. BLOG INTERFOTO.EU may have what you want regarding the 50mm f/1.2.

It seems that dmartin92 was right, I thought Canon reused the older FD optical design, but despide using the same number of groups and elements, the lenses are slightly different:

I'm an early adopter to this lens and along with my 85/1.2LII are my favorite lenses for the 5DS.

Re: Canon EF 50mm f/1.2 L USM lens

Great images! I wish I could do that as well.

However, have you ever noticed that the lens has severe chromatic aberration under certain lighting conditions? Please see the attached image. Her face is pretty sharp. I pixelized her face for her privacy.

Yes I've seen it before but in extreme cases. I find that overall CA/purple fringing is pretty much in control with this lens. I can't wait for summer so I can use this lens again.

I have the first generation EF 85mm 1.2L which has some kind of dramatic way of rendering at 1.2. The background is like a painting and the subject sharp. It’s easily one my favourite lenses.

Would the EF 50mm 1.2L bring something extra compared to the Nikon 50mm 1.4G or the classic Planar 1.4/50 ZF.2?
