I'll do another one from the same trip today, also at 1.4. MAN, this is a great lens at 1.4 (when it sticks)

WOW that is amazing! I can't wait to get my hands on one to test it out.
Life is like photography. We develop from the negatives.

did you check you measured your distances from the target to the mark on the top of the camera that marks the sensir plane like a O with a line through it and not the front of the lens?

FoCal tells me the distance, but also double checked with the distance scale on the lens.

Tried it more outside today, and it's the same story, I can shoot 30 shots, refocused in between, and it is VERY sharp and clearly spot on. Then turn around at another distance, go back to the first and it just won't lock no matter what I do. And it's not always about the distance, but some subjects I just won't focus on, and then it will. Impossible to get consistent hit or miss.

when you do your test shots maybe try NOT use focal
just set up on a tripod and measure with a tape measure from the target to the mark on the camera body for 0.4, 0.7 and 1.5m thats what I did then i took a bunch of shots to check.
removed the lens put into the dock tweeked calibration
put back took more shots etc.

I just wonder.....I do not own the Canon 50mm f/1.4 or Canon f/1.2......are they always spot on with the autofocus? I assume you have to AFMA with those as well. And they may differ in copies.


I am going to pickup my Sigma 50mm f/1.4 Art tomorrow. I am very curious about the quality of my copy. Anyhow I ordered the dock based on experiences here. I may go into Focal AFMA on Friday

the canon 50 f1.4 is very inaccurate

What I would really like to see is a string of photos comparing the Canon and Sigma 50 f/1.4's.  Anyone have access to both?

I decided to run mine through focal pro to see how my dock calibration was
it came back recomending a -1 (not much i'll leave it on and see how it goes

see the screen shots of the AFMA and consistancy check

also sharpest aperture is f4 with a rating of 1950!
but f1.4 to f10 are still 1800!

this was all shot tethered on a tripod
lit by an LED video light
focused via live view and tweeked on the eyeball of the dragon for peak focus
exposure was set to approximately +1 EV for all shots
Auto White balance

images are JPG straight from the camera
