I’m about to take the plunge and get myself one of these. Having read that there are some examples that are, shall I say- not as good as others. Is it a case of getting these “not so good” lenses recalibrated or is it an inherent problem that is more difficult or impossible to fix?

I have one and it's sharp. Just make sure you hold your gear steady anyway. Love using it for sports. It is true, not as sharp as the 70-200 2.8 IS, or f4 that I have, but still, very nice. Skill is important, too.

Like anything that's manufactured en masse, there will be always some sample variations with performance, doesn't matter what the product is. That being said, I have yet to have any problems with any of my Canon lenses, including my 6-year old 100-400L. As someone has already mentioned, skill plays a large part. My advice is to read up on long lens technique and don't sweat it.

I have to agree with the opinions above, especially the importance of skill and experience. I've had my 100-400L for about 4 months now, and if you were to look at the progression of photos I've taken with the lens over that time, you might come to the conclusion that the lens has gotten significantly sharper over that time!

BINGO bw!
People come from 100mm territory into 400mm territory and wonder why their pics are soft at 1/250 sec. I always aim for 1/1000sec as well as IS on to ensure a sharp pic :D It takes time for most peoples pics to improve.....
If your birding, then close close close is the way to go, even with 400mm at your disposal. You can't take a pic from 100 feet away and expect magazine cover detail. Its a great lens !!

Hopefully you don't mind me hopping in on this stroller. I started an almost simliar thread a few days ago and am still on the fence. It does seem most that love the lens say it's mostly user error. It does make sense.

If by chance it does have to go back to canon for calibration, what is the app cost?

Thanks everyone for the comments and advice. Lens is on order and I'm eagerly awaiting delivery. I'll let you know how I get on with it.

I sent mine in for a checkup/adjust at one point and it was about $280 or so, IIRC. It's a fantastic lens, though, and mine gets used and abused pretty heavily; it's yet to fail me...any bad pics I get are due to me rather than the lens.

I have to agree with the above, if I miss a shot, it's usually my fault not the lens.
And as far as a learning curve, I found it very easy to adjust to.

It is a great lens, just watch your speed as wide open at 100mm is only 4.5. Have to raise ISO at dusk pretty quickly to keep shutter speed up.

Buy with confidence, it's a great lens.

If you buy new and send it for calibration within the first year it is free under the warranty.

I've got one that's 10 years old, and I'm thinking about dropping it off for an inspection/service just because it's 10 years old. It works fine, has no issues, and couldn't be identified as "vintage" just by looking. Sorta like a watch...every now and then, it deserves a good service...

It's a very sharp lens, very. There are tricks to using it.

First, don't use a filter, one more piece of glass to go through, esp at 400mm. And some say there are other hypertechnical reasons as well, ? filters don't work with stabilization.

Second, use a tripod, and if there's wind, a weight on the center column hook. Or at least a monopod.

Third, use as fast a shutter speed as possible.

Fourth, use your microadjustment to calibrate it to your camera body.

Fifth, keep the tension ring relatively tight, so that when it hangs down in your hand, the barrel doesn't extend on its own with gravity and whack the stop mechanism.

Last, I use TF Camera Repair in NJ rather than Canon for overhauls. They test to higher standards than does Canon.

But most of all, it helps if you've played the trombone in high school.

Wait huh? I use a filter on all my lenses including my 100-400L when I had it for years and never had issues...
