bobby, If I had not packed it away to ship, I would do a video and post it.
the focus inconsistency unfortunately happens on both bodies. Admittedly, I may be more anal than the average guy, and reading some of the amazon reviews with people complaining about focus issues, let me to do exhaustive testing, that I may not have done.
However, it definitely, without a doubt or question, is not as consistent focusing as my 35 1.4 or 85 1.2. and when it misses, it can miss by enough to render image out of focus even at f2 (look at my example on the first post). Most of my testing is on 5dII which is the body I will be using this lens on. It is also definitely slower focusing than my 35L, but that may be normal. if the focus is nailed, sharpness is very good.
I tried this on the MFA target test on screen, as well as a paper printed target test. I also used the lens, with the same results (at 1.4, I would say only 30% shots are spot on, 40 % or soft b/c slightly oof, and then about 30% are pretty soft. I kept on thinking maybe its subject movement, or light, or whatever...., thats why I did all the controlled testing.
Now, the lens is very well reviewed on b&h. so I would not get nervous if your copy was working fine. Honestly the lens also has about the same (maybe slightly worse) focus consistency than my sigma 50 1.4, but that is my most focus riddled lens, and I did not pay 1500 for and L lens, to get anything less than 90% reasonably accurate focus rate. ...Show more →
I have found a certain degree of focusing issues with ANY lens on my Canon bodies if it is f/2 or faster.
Although the Canon 50 1.4 is the one that really stands out in a bad way, more than the others.
That said, and it's hard to say for sure since exact nature of lighting, subject, distance can greatly alter results, but it seems like your 24 is likely having more focusing issues than mine, but again hard to say for sure. You say that even with the target that has worked out to be the single most favorable for it and that under the single most favorable lighting for it (not what you think would be most favorable since that can be deceptive, but what actually works out to be most favorable through testing) that it still only hits 50% in focus below f/2?
