Canon EF 24-70 F2.8 mk11 focusing issues

[Dash]

Hi, I covered a wedding yesterday. Used a 5Dmk111 and a Canon EF 24-70 F2.8 mk11. A lot of my shots were at 24-30mm @ f2.8 or f3.2 and a large proportion of these were out of focus. The chosen focus point was in centre but the focus in the shots was at extreme left or right! I used the same camera body with a 70-200 F2.8 L without trouble.

The 24-70 lens is only 10 months old.

Been shooting for the last 30 years, so can confidently say "human error" is unlikely.

Has anyone else had this problem?

It is the 24-70 2.8 MkII (I wish there was a IS version of the f2.8!:-) )

I see your point, but the Mk II is already big and heavy enough.

"I see your point, but the Mk II is already big and heavy enough."

Not wishing for it or opposed to it, but the other makers seem to be able to include image stabilization.  IMHO, image stabilization isn't a deal breaker or maker.  It is the best lens of its kind made. All comers, no question.

"...big and heavy enough."

How about price?  IS goes in, price goes up!

Yeah, that too. But I already have a 24-70 II, so I don't care what they do next.

Used the 24-70 (and occasionally the 70-200) in a volunteer photo shoot at our local library the other day. It went well enough that the client was pleased.  8^)

"It went well enough that the client was pleased."

And there lies the bottom line.  No spec, no review , no MTF chart, no nothing, matters as long as the client is "pleased".

Oh yes it’s USM not IS

Oh yes it’s USM not IS, what’s a different between IS and USM I didn’t notice this before

USM is the type of autofocus motor.

IS ("Image Stabilization") is a method of correcting for camera shake.

Wanting to drop two grand on a lens you may want to educate yourself better on what the lenses actually are and the nomenclature.

I am no expert in this arena, however, I do have the same lens and noticed a slight back focus with my 5Ds. After making a slight micro adjustment, the issue is resolved and I don't use any filter with it other than Lee's ND filters. That said, I don't do portrait or wedding, as said earlier, I am still learning how to take photos.

Cheers,
