I just got a 2nd hand 70-200 F4 IS and it is quite soft at 200mm until around f8. I owned a non IS version in the past it it was very sharp at f4- so I feel there is something absolutely wrong with it (no part is sharp so I know it's not a MA issue, I've tried both of my bodies with the same result, shot from a tripod during a sunny day is on and off, SS above 1/1000). So.... I'm curious what the options are, I've never had to send a lens off, what am I looking at as far as potential solutions as well as costs involved in sending it in? Any help would be great!

Sorry to hear that. :( I'd say there's something wrong with the lens. Below is a link to a photo I just posted from that lens, and it is fairly cropped. While you can see the EXIF data (f/5.6), this was hand-held on a hazy day from a few miles away. Although processed in Lightroom, I've done no additional sharpening. I've completely enjoyed my copy of the 70-200 f/4 IS, and have had no troubles with it.

Can you return it? If you can, I would recommend it.

For service, others will have to comment on that. My guess is there's a minimal fee. They'll evaluate it, give you an estimate, and you'll have to choose if it's worth repairing.

Good luck!

Yea, you can see the lenses I have. I would consider this lens sharp at f4. It does sharpen up at f5.6, but it is very decently sharp at f4. Should actually be a tad softer at f8 in the center than f5.6-f6.3, certainly not substantially sharper.

As far as sending it it, most likely it will cost the standard labor charge (I guess ~$200 or more). So returning it if possible would be better.

One caveat. This lens IS soft near minimum focus distance. So if you were doing your tests at close range (< 2m), then yes, it is normal, especially at 200mm.

My 70-200/4 IS is broken. It can't stop down smaller than f4. OK for real I wouldn't know if it was actually broken as its perfectly sharp at f4.

I would do some tests on a tripod with live view to just check its not a focus calibration issue, but sending it to Canon is probably going to be your route.

Indeed second hand, I have yet to every buy a lens brand new with the exception of a Tamron 28-75, and I have had probably 8 lenses since and this is the first problem I have encountered- yet I have saved probably a couple thousand on all of my lens purchases....


Thanks for solidifying that I'm haven't forgotten how sharp this bad boy should be. Into Canon it will go.

(Emphasis added in the quote.)

Actually I've bought two L lenses used. They were previously rentals, and I saved a bunch of money on them. While I'm not typically a fan of "used" anything, these have proved to be quite good.

I had this lens repaired by Canon. I dropped it, and the IS started acting up. I could get very sharp images with the IS off, but as soon as I tuned it on, the sharpness was unsatisfactory. It cost me $560 plus shipping both ways.

In that case, since it was a fall, the insurance covered the cost of the repair.

Can you return it? A broken zoom mechanism can be very expensive. I've encountered the same issues you've had, and I returned the lens/filed claim. On one of the lens, $600 repair bill, that's near the full cost of the lens! Canon refurb may have some of those lenses.

I just wanted thank everyone for their input, I sent it to canon for focus adjustments, and it came to a total of 190$ and got it back with the sharpness I knew it was! The seller even paid for half if the fix so yay!
