Thanks for all the feedback. 

Yochanan-  I'm sure it's just the lens, as every other lens I've tested on the Mark III is superbly sharp.  My Sigma 70 2.8 macro is the sharpest lens I own (one of the sharpest lens anywhere) and it is incredible on the new camera, so I have no issues with the body.

 I think I have figured out that my 24-105 has a resolution characteristic very similar to the tests depicted on the SLR Gear website.  http://www.slrgear.com/reviews/showproduct.php/product/145/cat/11

If you look at their 3D blur plots, both on the crop sensor and the full frame sensor tests, it shows the lens to have it's worst performance at the 70 and 105 end, which is where I was comparing it with my 70-300L lens.  It looks much better at 24, 35 and 50 on those plots.   The edges at the higher focal lengths look pretty poor on their plots, but the centers are OK.  I think this is the only lens I've seen on their plots where the best image is  at f11 (on their 70mm test).  Usually the sharpest margins are at 5.6 or 8.

 I will do some more tests of the lens at the lower focal lengths on my T2i to compare it to my 15-85, but I suspect there won't be as much difference at the wide end as there is at the tele end.    I do at some point need to consider getting a prime or two at the wide end, but if the 24-105 is acceptable at those focal lengths, I guess there is no hurry.  May start with the cheapie 50 1.8 before I take the plunge into a 35L or a Zeiss.

I tend to shoot two types of things,  landscape/scenery, where I'd like better full frame sharpness than I'm seeing at the tele end,  and I also do a lot of flower photography, where the margins are usually not as important.  The first day or two I had the new camera, that is what I was shooting mostly around the house and was fairly pleased with the results for flowers, even at the tele end of the range.  It wasn't until I did the tests a few days later I realized the problems away from the center.   For the time being I've decided to live with the lens, and do some more tests next weekend before deciding if I want to send it to Canon for calibration.

My 5D III &  24-105 are currently with Canon Service Center, Irvine CA. I posted the softness issues last week - some peeps were making joke of the post >:(   

 "hey my 5D III doesn't make coffee" etc....

 Anyway, I should have the body & lens back soon - stay tune for update. I think you should give Canon another shot before return it.

Got 5D III & Lens back today...No issues with the body. According to Canon Tech, they calibrated the 24-105 lens. They showed me pictures before & after calibration, It's huge different.

I will take some shots after work, so far so good :)

Best of all, it was completely FREE. The front desk people VERY NICE and FRIENDLY

By calibrated they mean micro adjustment i suppose Dylan?

JR, Stay tune...I emailed Canon and requested for the repair info on my 5D III & 24-105 lens. I'll let you know the detail. Dylan

No, usually they adjust the autofocus circuitry on the lens.  I sent a fast prime that was blurry at f/4 and they adusted the lens and it was fine afterwards.  If you send the body, they'll check that the lens is "matched" to your body.

Wait too long and they will stick you with a refurb.

Not good when you pay for new.

I didn't buy the kit. I bought the 24-105 used 2years ago. It works fine with my 5d II & 60D, but not with 5D III - kinda soft. After Canon did an "electrical adjustment", pictures are must sharper now :)

I'm not sure all lens need to be calibrated. Instead of Micro Adjustment - Canon did "eletrical adjustment" on my 24-105...pictures are much sharper now. I will post some pics after work.

my 70-200 f2.8 II IS is sharp before and after 5d III visisted Canon Service Center  ;)

I never really like the 24-105, to much lens flare not super sharp. It's a good light walk around lens that cost to much

- the 24-104 is a low cost L lens
- looks pretty sharp to me
- the low weight makes it suitable for fast moving sports
- fast af makes Servo mode work well

Here is one from the weekend - on a low tech 1Ds3, should be better on the 5DIII, high speed panning with a heavy lens is VERY difficult



Camera Maker: Canon
Camera Model: Canon EOS-1Ds Mark III
Image Date: 2012-04-01 13:01:25 +0100
Focal Length: 45.0mm
Aperture: f/13.0
Exposure Time: 0.010 s (1/100)
ISO equiv: 100
Exposure Bias: +0.33 EV
I don't totally hate the lens, its no where near the image quality of the 24-70 but it's much lighter. My 24-70 can handle lens flare nicely that would make the same image from the 24-105 unusable. ESP at a reception using strobe lights

Thanks dylan.  This is very interesting since I personally never had to send a lens for calibration.  I may send use that service in the future then, seem to be working well!

I just upgraded from a 7D to the 5d3 so I am in the same situation as you. 

I am happy to report that the 24-105 seems just as sharp as my old workhorse the 17-55 f2.8.  Very sharp.  Better build quality.  Cool red ring!!!

I also have the excellent 70-300L and I would say it is even sharper on the 5d3.  I shot a picture of a car 100+ feet away across the street and you can zoom in on the camera's lcd to actually read the temperature rating of the tire (tiny black letters on a black tire)!!!!

Man, I love this camera!!
