This picture could've been done with the 50mm f1.4 aswell. But I drift your catch. Don't know why to spend a
grand more as told before, but well, a f1.2 pic ;)

Actually, that shot couldn't have been done with the 50mm f/1.4, because it was taken at f/1.2.  :)

I had the 50mm f/1.4 once long ago and it's a decent lens, but only decent.  The differences between the two (and other 50mm lenses) have been covered here and elsewhere 1000 times so I won't go any further.  I'll only say this:  A friend of mine once dropped his 50mm f/1.4 to the kitchen floor and it absolutely fell to pieces.  I've (embarrassingly enough) dropped my 50mm f/1.2 several times and it's still in one piece.

Yes, you could. Assuming the man is exaclty 3 meters away, just go 25 cm closer to him and crop the picture to
the same frame.  Voila, you got the same depth of field (0.25m). At the same time you could adjust the ISO to 1/3
of a stop brighter if you like the speed of shutter.

Sorry to disappoint you. Physic beats money ;) And the colors are not that well choicen...

Unless I had a bad copy, but my last 50 f1.4 couldn't be used at f1.4 to 1.6 - just soft. From f2 and down the f1.4 performs better. Contrast & color are not there.

My 50L is really sharp @ f1.4 to f1.6. Focus shift starts from f2 to f2.8 - shifts about 1.5" or so. Look forward to have this issue fixed in version II.

I can't chime in here because I don't go that wide.  Heck I was nervous with my 135L going to f/2.2 in basketball  ;D

Speaking about physics - if you get close, you cannot crop to the same frame. You can do that if you step back. In neither case you will take the same picture.

If you do crop, and the crop factor is about 1/3 stop indeed, you get f/1.6, not f/1.2, where f=57 or so.

Learned friends,
One week ago I bought the Canon 50 mm f/1.2 for my new 5D Mark III, specifically for the very shallow DOF at f/1.2.
I am however disappointed with the sharpness of the lens at f/1.2. At f/2.8 its excellent.
I enclose two 100 % crops showing some text at f/1.2 and at f/2.8. The two images were taken at an angle of about 30 degrees, thus making the test independent of AFMA settings - it is clear that there is a focus shift, but that is not what I am complaining about.
I trust that you will agree that the f/1.2 image is a lot fuzzier than the f/2.8 image. My question to you experts is whether such a difference in sharpness is to be expected or if I should return my glas? Your help is highly appreciated :)

Hello Birger.Niss

Took this shot of my daughter having her bath as an example of "Real World" results...(Canon 1Ds MK3, 50L @ f1.2 and 580EX II) Note the DoF is so bloody thin that even her nose and left eye are already OOF :P

All I've done to this picture was a bit of white balance correction and cropping to 100%

I don't think there is anything else that I could possibly ask this lens to do for me, You can count her eyelashes!!!... Everything else is just semantics and virtual blablabla

What truly amazes me about these threads/arguments is that people only post shots from one of the lenses.  "The 50 f/1.2L is better than the 50 f/1.4, see!"  And then we get a 50 f/1.2L shot and NO 50 f/1.4 shot.  Granted, in this particular case the shot was done at f/1.2, so obviously no other Canon 50mm lens could have taken the shot!  If you REALLY want to know if it's better though, wouldn't you need two shots, taken at the same aperture/settings?  The only comparisons I have seen are on Bryan Carnathan's site. 

However,

I don't think there is really any reason for 50 f/1.2L owners to defend and justify their purchase/ownership.  If it is working for you and you love it, do you really care what anybody else thinks?  I know I wouldn't.

Hey bdunbar79 how is it going ??

Yeah I agree with the comparing apples with apples :)

On this particular tread tho' the member asked specifically about the 1.2 and opinion from 1.2 owners to check if his copy was faulty or not. I can't say for other people, but I was just trying to help the original poster with his question.

If we go back and read the thread, it seams that owners of 1.4 lenses jumped on the wagon and tried to justify ( scientifically and otherwise ) why the 1.4 would do the same job for 1000 less or something like that...I think this time is the other way around you see  :o

Maybe I had a bad copy or I'm still upset and so my answers are coloured with my historical feelings. My pictures at @f1.2 weren't as sharp as yours, but the "problem" was more that the 50mm 1.4 outchallenged the 1.2 lense by far. Maybe there are some good ones out there, but I heard the same problem from other people.
 
From f2.5 on, the lense was a beast, and the colors and buildquality were outstanding... and if you need the red ring or simply the 1.2 you can't get any better from Canon at the moment. But the price and the open apertures weren't even at the niveau of thr 50mm 1.4. So it was sold. This is pixelpeeping. Of course it is, but for a $1500 lense against a $350 lense it's something which is appropriate, I think. Otherwise we all could use a 350D and a 50f1.8.

The 85mm 1.2 II was the opposite, it was a great update to the 85mm 1.8 in all ranges, except weight. The 85mm 1.2 has some other bad points (no weathersealing at any point), but that's ok for portraits in rooms.

I think everyone should use any lense he want's to, but there were people disappointed of the sharpness (topic) and I just gave my 50 cents because I had one. A red ring doesn't always justify anything. My old Zeiss f2 was sharper, and it was from 1958. At the moment I've no 50mm for the Canon anymmore, I sticked more to the fabulous 35mm range.

Here is a picture from the 85 1.2 with a part as crop. The Crop is from the jpg out of cam, no sharpening applied. This was handhold, I think there is more possible with mirrorlockup and tripod ;D

Sorry for maybe some harsh words, I love you all  ;)

I compared both a while back, and a zeiss 50 1.4. I think a few other people have too (just the canons). I stuck with my 50 1.4 mainly because I love the lens and could not see any reason to spend $1400-1600 on a minor upgrade at best. The copy I had also suffered major focus shift (was a CPS rental) to the point were f/1.2 was -2 AFMA and f/1.4 was -9. Until I got to about f/2.8 the focus shift was still very evident.

That's all I was saying too, and admitted it was just my opinion.  I don't think the 1.4 is better than the 1.2 by any means.  I do not, however, believe that the 1.2 is worth that much in price over the 1.4.  It does not take away from the quality of the 1.2, it's just to me, there isn't nearly enough extra quality to spend that much more money.  And yes, just my opinion.
