Hi All,

First post!

I recently got back into DSLR photography after a few years off. Just picked up a used (but pretty new, only 6 months old and 2500 clicks) 5D2 and the accompanying 24-105mm. Lens is a UZ06xx which if I'm right means it was manufactured in June 2011.

I took it out for a shoot and came home to some pretty disappointing results (everything was very very soft). After some research I found out it's a pretty common issue and to correct it with AF microadjust.

Long story short, a micro adjustment of +20 is giving me the best results, but that also leaves me wondering if it would be even better if the camera could adjust to more than +/- 20. Luckily I'm getting good results across the entire focal range with +20.

I currently live in Sydney Australia and there is a Canon service center in town. Should I take the lens in for service/calibration? If the adjustment needed was say +/- 10 I would be ok with it, but since I had to MA all the way to the end of the spectrum it makes me wonder. How much can I expect to pay for a calibration? Maybe I could even have it done free since it's so extreme?

I'll attach a 100% center crop of 0 and +20 MA. The focus point is on the "5". Shot at 70mm, 3.5m from the target. Tripod, remote release.

Also, is this the "fault" of the lens or can the camera have something to do with this as well?

Thanks!

Have you tried the lens of a focus target at various focal lengths? This seems a bit off.
I wonder why the original owner would sell after such a short time.

Yes I tried it at several focal lengths, all being really soft at 0.
Bought both cam and lens from same seller. He was a videographer with two 5D2's, so probably never used AF anyway. Was selling to fund a 70-200 L IS 2.8.

I think it would help to send both the camera and lens to canon to have them set them back to factory specs. +20 is pretty high, if it was +10 not so much even my 1d3 and 500mm back from canon I still have it set to +5 with the 1.4xTC on it and all three went to canon at the same time.

If possible, I would try to borrow another similar lens, or even a different one.
That way you kind of assess if you have a body or lens problem.
If the service center takes walk-ins, you might be able to consult with someone about your problem.

I would take the lens and body into Canon at Nth Ryde and have them check it out. But before you do so, check to see if it's under warranty. I was under the wrong impression that grey-import lenses were covered by an international warranty, but that situation changed late last year

Will try to take it to Canon tomorrow.

Anyone else had a similar issue with this lens?

I would definitely have it calibrated as it looks soft. My 24-105 is tack sharp, even at f/4 100%. The only issue with my lens is that it needs different micro-adjustments at different lenghts: -5 @ 24mm, 0 @75mm, +5 @ 105mm. Unfortunately I'm not able to make different micro-adjustments on the 5DII so I just leave it at zero and seems to do just fine.

The lens might be off (probably) but something might be wrong with the body too. I would take both in and let them check them together so you have the best chance of getting a positive result. If you have other lenses you will be using on this 5D I would take them in too. I had an issue with my 24-70 f2.8 and I sent my 7D + all my lenses in, everything came back sharp and clear. It was like every lens was made for that camera. I was very pleased with the results.

Took the camera and lens to Canon.

The tech checked out the camera and lens. Said +20 is still within acceptable range and the lens is fine, but would calibrate it for $93 AUD. Since I'm happy with the results at +20, I decided to keep my $93.

I did get the camera cleaned and sensor cleaned since there was some dust on the sensor which cost $68 AUD.

Thanks for the replies.

One easy test: Setup a tripod and stationary subject(s) in a such a way to reveal any focus shift. Take a picture with AF. Then manually adjust focus using live view and see if you get something more in focus at a different setting. If manual focus results in more accurate focus than AF and it points to a MAF setting greater than 20, you got a problem.

Also, you are calibrating a zoom lens. I wonder if the limitation +20 is fine at both ends of the zoom range.

What sort of MAF settings are you getting with the rest of your lens? Are you confident that your camera body is not at the extreme edge of the acceptable range?

Personally at +20, I'd see about calibrating lens and maybe body to get a value less than that.

Thanks, will try your suggestion.

I haven't done extensive testing so see if some lengths benefit from less than +20 , but +20 definitely clears things up throughout the range.

As the 24-105mm is my only lens at the moment, I won't be able to tell if the body is off. The tech didn't seem to think that was an issue, but maybe he was just being dismissive. Will have to wait until I get my hands on another lens, but for now I am content.
