I've been having focusing issues with this lens. I always use center point to focus and I double check the red dot is on my subject and still the lens focuses somewhere behind. I am talking about 30% focused and 70% OOF :( Usually happens on the wide end, performs much better on 70mm

Same as mine. I have the canon service center check my lens for soft focus issue. I can't wait to see the difference once it gets back.

Anyway, this is a sample photo from my lens. Is this acceptably sharp enough for this L lens?

EXIF:
Handheld; I've used Live view and 5x (or 10x I really can't remember) to focus on his eye.
Exposure 0.033 sec (1/30)
Aperture f/5.6
Focal Length 40 mm
ISO Speed 800

No PP made, no sharpening. I've chosen M (Medium Jpeg something like that hehe) for the image quality.

EXIF:
Handheld; Focus on the center letter "C"
Exposure 0.013 sec (1/80)
Aperture f/4.0
Focal Length 27 mm
ISO Speed 800

I had problems in both ends; 24mm back and 70mm front focusing. They fixed it in Canon service, no problems any more. I recommend sending it to service, especially if it's under warranty.

I've also noticed that modern LED lights makes AF's life difficult. My lens is always focusing back a bit indoors with LED lighting.

Well... I don't know if this lens has more problems than other lenses. For the lenses I have owned (4 different lenses + this one) all have visited Canon service for a good reason. Each had AF issues in the lens. Only 1 of them was bad even after second visit.. But that was the EF 50f/1.8, so just as much quality as that amount of money will get.. ;)

Just go for it. If you should face any problems (which you probably won't), just get it fixed! :)

Might as well send it in, I sent mine in and got it back very quickly, was suprised at how fast the turn around time was. They recalibrated and fixed any front focus or back focus problems, and I also had a little clicking noise when turning the zoom ring at the 35mm mark it would click, they said that was a mechanical part that had gotten loose so they fixed that as well.

I had the same issues you were having, now I'm getting soem of the sharpest photos I've ever taken that look even better then some of my primes.

Thanks all for the replies. Canon Mexico is super slow I have been waiting for two months for my 35L to be fixed, once I have it back I will send the 24-70 in, hope they fix it as it is very annoying to miss so many shots, some were important.

Here's one keeper

I had no problems with it on a 7D but have heard that it is a problem on the 5Dii in low light and using outer focus points. Then again what doesn't work for one may work for the other, use it and enjoy it cause when it does work it sings on the 5Dmkii.

Well, the 7d has a better AF anyway. :)
