Hey everyone,
After using the 1dxii for the last 5 years, I bought myself the 1dxiii last week.
Now, overall this camera is insane and I love it, but I found something that bothers me a bit.
Outdoors, during daylight, the autofocus is crazy fast. (I'm using the full af zone with initial servo af point) now, during night time or even during day time if I'm in a room that doesn't have direct sun light it feels like the autofocus is laggy, suddenly it's not that fast, and it feels even slower than the 1dxii, and I checked both cameras in the same scenarios, 1dxii autofocus speed is consistent on both cases and 1dxiii is not, feels like there's a half a second latency from the second I press the af button until it's actually starts working, and the af point movement becomes laggy.
I using all L prime lenses (checked them all)
Brand new 1dxiii - a week old, already shot one wedding with it.
Please help!
Solved! Go to Solution.

So I figured it out.. Since I never update my cameras firmware until I absolutely sure there's no new issues... When I got this camera, for some reason I decided to update it from 1.6.2 to 1.7.1 (the new update)... Big mistake, now I'm back to 1.6.2, and everything is fantastic. Thank you everyone for your time and effort

And compare that with your 1dxii... And tell me where it's more consistent.

I haven't noticed any AF lag issue with either my series II or III bodies. I just set up a 1DX II and a 1DX III body with full zone enabled and tried both servo and single shot using 24-70 and 70-200 f2.8 glass on both bodies which seems like a bit more critical test since focus won't be quite as fast as using my great white primes.
I focused on a close spot then focused on the target cat about 12 feet away in a room dark enough that the cameras chose ISO 102,400 for a standard exposure at 1/125, f2.8 which should be darker than any wedding you would shoot. Acquisition was quick and sure with both bodies but I think you need to actually compare your 1DX III to another 1DX III body because individual perceptions vary.
For sports, I generally have 24-70, 70-200, and 400 f2.8 Canon glass on three different bodies; I shoot in manual mode with auto ISO and with the lenses wide open and shutter speed @ 1/800 to 1/1000 ISO is generally in the 8,000 - 16,000 range and focus acquisition stability/speed is excellent and I don't notice any difference between the II and III. The II was noticeably better in lower light than the original 1DX but with AF performance for what I use (single point with expansion, always in servo mode) the performance of both the II and III are exceptional with not enough difference that I have ever noticed.
And Tabs is clearly enjoying the travel case for my Hensel flash beauty dish a little too much! 🙂 She is a ISO 102,400 photo from this test.
