Customer Reviews

most used lens in my bag!
The lens can be found on my camera 80% of the time. As a wedding photographer the range is great for tight spaces where brides get ready and reception shots. The 2.8 aperture is great and where I keep it most of the time.

Why a 4 instead of 5? Does need to be serviced at least once a year to keep focusing sharp. Canon factory repair can service it no problem and then it focus' beautifully. Before I send it in I notice it back focusing.

Very nice images, but heavy
I picked up this lens along with a 40D for my wife. I did research for months and talked to every one I knew about what lens to buy. I finally settled on the 24-70 2.8L mainly because of the volumes glowing praise for the quality of images it would take.

the good:
The reviews are right, the pics are breath-taking. After just a few weeks of dinking around with the camera my wife is taking shots of our kids on par with what we get at the local semi-pro photographer studio. We also have some nice shots of bugs/flowers, this isnt a macro lens but it does a damn fine job at it if you ask me.
The long and short of it was I wanted 1 lens to use for pretty much all occasions and this delivered just that.

The Bad:
Its freaking huge! I was ready for heavy, and it is a little heavy, but the lens is so big my wife dosent like to take it with her. She complains it makes her stand out in a crowd. With the lens hood attached folks tend to stair making it hard to get candid shots. There is no-chance of blending into the background with this beast stuck to the front of your face.

The conclusion:
Was it worth the 1300 spent? Heavens YES! This is a fantastic chunk of glass. Ive had the chance to shoot some other glass in the last few weeks and I keep going back to it. The only reason for 4/5 stars is the size.

Awesome!!!
LOVE, LOVE this lens!!!!! It produces beautiful, SHARP images! It is a must have!!!
