I notice there are only a few owners of the Canon Mark III on this site but I just wondered what your opinions on the numerous internet threads and from Canon themselves stating problems and asking for recalls from affected camera's, notably the focus.
I have tested mine with numerous lenses, static and moving subjects in many different types of light. On it's maiden voyage I had it focusing at night at ISO 1250 on fast moving fire dancers using the 70-200mm F2.8 IS with 95% of them keepers.
Any users here had any focus issues and if so could you please elaborate on what they were so I can try and replicate to see if my Mark III body is also faulty ?
Thanks in advance. |

afaik, the conditions are 'hotter than average' temperatures, AI servo focus, in bright sunlight, shooting in burst mode.
I know a few people in Texas who've seen problems ;) |

I also think that you have to be using a 300mm f/2.8 or longer lens.
My longest is 100-400 but it's f/4.5-5.6L. My next is the 70-200 f/2.8L. I have not experienced the problem even in the summer heat.
So while Canon claims that "not all units affected", I would appear to have one that is not. (I say "appear" because, as I said, I haven't been shooting a 300mm f/2.8 lens, so I really don't know for sure).

From the official press release....
"Bodies with serial numbers 501001 through 546561 are said to be affected, and Canon are preparing to offer free repairs from late November."

I think all that does is establish a "limit". In other words, "definitely no cameras AFTER 546561", but not necessarily all cameras before. If it was ALL cameras, I would think they would have issued a recall.

Thanks for that.
I have no lenses beyond 200mm.
85mm F1.8
24-70mm F2.8
135mm F2 with 1.4x convertor
70-200mm F2.8 IS
And have shot in various temperatures, lights, fast and slow moving objects and am continuing to do so. My camera falls into that " batch " but have yet to replicate the problem.
Some of the photo's were not in focus but when you're shooting birds flying towards you I dont think there's a camera in the world that can nail every single one perfectly?

do you have to 'prove' the defect to have the repair done?
what's the worry if you know your SN# is inside the affected range?
they seem to know there 'might' be a problem...

Agreed.
Canon said they were going to announce a way to test if your model is defective, but no news ( as of yet anyway ! ). |
