Canon 100-400 Fell Off In Quality After 2 Years

Hi,

I'm using the Canon EF100-400 lens for more than 2 years now and while I have been satisfied with almost all results for quite a long time, I recently found many pictures that do not really satisfy me anymore.
The overall quality of the pictures seems to be lower although I am sure that I did not change the camera settings or so. The colours look somehow flat and many pictures are not that crisp sharp they used to be. There are also many which are sharp on one side and become softer to the other side.
I tried to change the settings but I didn't notice any difference, so could it be that the lens just became old? I have used it quite often and beside the quality and sharpness issues there is also a problem with the arresting mechanism.

Has anybody else here similar problems?

Stefan

I had a 100-400 a few years back and seemed to be one of the unfortunate ones. I ended up disposing of it, although lately I miss it's alround capabilities.
I did experience softness on one side towards the last few months which was pretty much rectified after a very expensive autofocus motor replacement and recalibration. This softness was definately not present when the lens was new. I also suffered IS failure when it was 6 months old and it had to have a new IS mechanism. I eventually lost faith in the lens and it became unused when I purchased a 70-200.
As I say now, there are people that haven't had a problem and it's still a good lens.

Same problem: Its been 2+ years. Colors and contrast are a bit lower, but I think thats because of the lens coating.

I want to recalibrate the lens BADLY. Is it a good idea or should I leave in the orginial state? I heard a lot of positive feedback from US calibrations (Irvine and Jamesburg Canon), but dont know about europe.

I've used the 500 F/4L, 300 2.8L, 70-200 2.8L, but the 100-400L is just so useful which compensates it being less sharp than primes.

Sam,

Can anyone shed some light on the recalibration service? Is it actually the lens or the body, or both, that would need to be sent in? How much does it cost, how long does it take? Was there an improvement in your photos?

Interesting to hear that others here have similar problems. Too bad that the warranty period of my lens has just expired  banghead . But I think I will ask Canon if they can check it for free as a gesture of goodwill (don't think they will do so but it's worth a try).

I would like to know this also.

It should be just the lens, should it not? Since there is no guarantee that you will be using that lens with that body forever, Canon just calibrate it back to the 'standard' I would have thought.
