How's this - it's a stack of 12 frames, 3 exposures at each of 4 focus points
Need to find some more interesting subject matter for this technique
Canon-convert, thanks for your reply. Are you using windows 7 or 8 or Mac? I'm using Windows XP which doesn't support LR4. I may just have to upgrade to at least windows 7 and then get LR4, too. $$
Mac
but that might not be the issue... wait for others to respond back before doing any upgrades

Hi canon_convert,
I'm not 100% sure on refurbs item. My guess is you should be fine since your lens is till under their warranty.
Just tell them what you just told me - "you bought this lens through their site and it seems to be soft on your 5D III"
In my case, I brought my 5D II + 24-105 down to service center in Irvine, CA. I told them the lens is soft and asked if they can help. They did calibrated the lens to match with my 5D II.
The lens did get little better after calibration, but no where near my current 5D III + 24-70 f2.8 II or 70-200 f2.8 IS II.
My 2cents: the 24-105L is not a sharp lens. I tried 2 copies, no luck.

If your lens or camera still under Canon 1yr warranty, then send both body and lens to Canon. Canon will do it for FREE. Canon will ask for the original sale receipt from authorized dealer - no exception. Without receipt, they will charge about $200 US for this service.
They calibrated my 5D II + 24-105 for FREE, since my 5D II was under warranty at that time.
If you can afford $1,600, I'd get a refurbished 70-200mm f/2.8L IS II USM. While it won't stop action as well as the 135mm f/2 lens except at 190-200mm, it's much more versatile and almost as sharp. Also consider the 100-400mm ($1,087) and the 300mm f/4L ($927) lenses, if reach and/or price is more important to you than aperture.
The next step up from these lenses is the 200mm f/2L lens ($6,000).

It's important to know that if your lens elements aren't tuned properly, no amount of in-camera micro-adjust will get you sharp images.
Have your lens serviced by Canon! You'll be tickled when you get your lens back and you realize that all of your stress is gone. Now you're the proud owner of a "Sharp Copy" and you don't have to be envious of others who were lucky and purchased a sharp lens out of the box.
Its not listed with Canon India yet. And YES if would be almost 1.5 times the cost here.
