p.1 #1 · p.1 #1 · Canon 50mm f/1.2L vs 50mm f/1.0L


Love the 50mm focal length but Canon's current 50mm f/1.2L is only good for f/1.2 to f/2.0, after that the 50mm f/1.4 is sharper.

I have been reading up on the reviews from William Castleman
http://www.wlcastleman.com/equip/reviews/50mm_1.2L/index.htm
http://www.wlcastleman.com/equip/reviews/50mm/index.htm

I have yet to find one that directly compares 50mm f/1.2L with a 50mm f/1.0L.
Fortunately I managed to get a hold of both.

I did a series of test with each 50mm from wide open to f/8.0 in 1/3 stops increments.
All shots were shot on a tripod delayed 2 seconds with minimum shutter speed of 1/100 and ISO 100. Flash is compulsory. Converted to JPEG quality 10, 100% crop with standard DPP settings.
Manual focus was done once only on each lens before shooting.
Taken with a 1D IV, 580ex II.

Here are the results.

Thanks!

The focus should be dead on for each lens, the numbers in the front may look sharper at smaller apertures since it's closer to the camera's sensor.

Good effort, thank you Sammy.

Listen, I'll give you $100 + shipping for the 50 f/1.0 box and the LH-D12 case.
You get to keep the lens.
How does that grab ya ?

Hey Petkal.... not looking to sell the box.
BTW, just to temp you.... this box is in as close to new as you can get with foam, LH-D12 case, original user manual and original lanyard.
It's in better shape than the one I sold to Gary (ghuff). Maybe you can check with him and see if he's looking to sell it. He's the only one I know who has the box.

Unfortunately, Gary isn't selling anything.......he has finally found his perfect 50 f/1.0.

Thanks for the test, but its really hard to discern much about either lens from the above pictures. The 50/1.2L seems to have slightly smoother bokeh - which is widely known - but optical quality is very difficult to judge.

Would you mind shooting some real world test targets? Something with a lot of detail.

This may give you a better idea.
It looks like the 50mm f/1.0L is slightly sharper.
As before, focused once for each lens before shooting.
Shot on a 5D II with 580ex II, 100% Crop, JPG quality 10, standard DPP settings, ISO100.

Interesting test.

At what distance was the USD 100 test done?

I'd really love to see a real world test match on FF

Yes and no.

You've answered my primary question, the distance of the 100 USD bill test.

The second part, real life testing on full frame it was not

Thanks for taking the time to test this this and sharing your results, but I'd still would love to see some RL results on FF

My 50mm f/1.2L is sold, will ship it out on Tuesday so I still have some time to test it.

All done on MF so focus shift is not an issue.
That's the reason I got the 50mm f/1.0L, 50mm f/1.2L AF is not consistent. Backfocuses a lot.

Uhh... focus shift most definitely *does* occur when manually focusing.

MF shouldn't affect the phenomenon. If focus shift exists, unchanged MF for a series of shots at different apertures (as you've done) is the only way of confirming it. The focus shift that people describe isn't an AF unreliability, it's an optical property of the lens -- the plane of focus is supposed to move as the lens is stopped down.

All lenses focuses wide open, only when the shutter is fully pressed, it stops down to the aperture you select and takes a shot.

Some non-parfocal zoom lenses shift focus as you zoom in or out but prime lens should not shift when stopped down.

Correct me if I am wrong.

Normally yes, but the well documented spherical aberration in the many superfast aperture lenses causes the focal plan to actually change when the lens is stopped down. Since focusing is done wide open, not stopped down, this can cause an issue.

The 50/1.0 L has a floating element which corrects for this, the 50/1.2L does not. Hence, it can suffer from minor focus shift under a very limited set of circumstances. Apparently it wasn't bad enough for you to notice it in your testing, yet many consider that "feature" to be a detriment to the lens.
