EF 100-400mm Lens Soft Due To Age?

Wed Apr 22, 2009 11:55 am

Hey guys

I havent used my EF100-400mm lens for a while but today i decided to go and shoot some photos. However, i noticed that the lens is rather soft. Can this be due to the age of the lens? (got it 2004)

Is there a possibility to have it repaired/improved?

link to the test photo: 300mm and 400mm

AFAIK you can send your DSLR body and the lens to Canon to make them adjust the lens and body as good as they can.

At least in Germany that's possible and a commonly used service.

But normally it should not become softer over time.... strange thing...

I'd recommend getting it serviced as described above if you feel it is soft.

But from these photos - it looks more like motion blur in about a 45 degree angle.

You might need the sensor cleaned as well - pretty big dust spot is visible (even I can see it - with my hopeless eyes).

I agree, looks like you got some motion blur in those.

Plus, the 100-400 never was the sharpest lens at full zoom, but I don't think it could get worse over time.

Definitely looks like a motion blur...therefore the lens could be OK.

Try using a tripod and see if the shots improve (for comparative purposes).
I'd rather be flying.

I am sure that the optics itself don't degrade over age (unless you dropped your lens), but electronics (e.g. IS) could go bust after some time... As others have already said, the shots show a kind of motion blur (did you shoot it with IS on (mode1) or was IS off?). A defective IS can of course be repaired, but it is costly...

What a co-incidence!

Mine got soft over the years too, heading to the service center tomorrow.

Mines had a harsh life, so I guess some lens elements might of shifted ever so slightly. Mines been shaken throughout its life.

Though most of the time I blame myself for the bad results, even though i've had it since 05.

Hey,

These photos are taken with a simple UV filter with a tri-pod. ISO 100 and autofocus (oneshot mode) F8.0

What do you guys think?

Looks blurry, not soft.

Try shooting some tripod shots with some different settings in optimal conditions and see if they are still coming out blurry

Where were you focusing on the shots of the roof? Are you using all points so the camera selects or just one? The side of the house looks pretty sharp so I was wondering if the camera used that as the focal point and the tiles are slightly soft / out of focus because of the shallow depth of field at the longer length? Just a suggestion. I'm having similar problems to yourself on the Sigma 50-500 since I upgraded from the 350D to the 50D; everything is very soft. Are you using the same camera body as before? It seems newer generation highter resolution cameras are producing slightly softer shots than less dense sensor cameras and showing up every minor flaw in the lens. Sigma have suggested I send the lens and camera back to them so they can calibrate the lens for my camera. I don't fancy sending nearly £2,000 in the post though!

I use a 20D and have always done so..and yes im sure that i focused on the center part
of the photo  Smile..Im going to test the lens tomorrow at the airport and see what it gives. I have also sent a message to canon, see what they say i should do.

How much does it usually take to have them clean/ take a look at the lens?

I think the base rate in the US is around $130. Usually it ends up just a little higher than that if it just needs a adjustment and cleaning. Some might balk at the price but, after sending them my 24-70 it's a bargain. They really do a thorough job.

I'd definitely be testing without the filter. Its the only ay you will see what the lens is really producing. Any filter reduces quality..
Imagine at worst a focus calibration but id be testing it more thoroughly in a more controlled way(tripod etc) b4 i pack up a lens to send off.

You still haven't mentioned whether or not IS was turned on. Especially when using a tripod, ensure IS is off.

Yes, IS should be off when on tripod. That alone will mess up image.

I checked all that images and all looks blurry not soft. Anyway you can always set sharpening in camera settings to sharpen more images... I am using it at first step in case of...

I bought my 100-400 about 3 years ago and I also have the feeling that the pictures came out sharper and contrastier when it was newer. I have to admit that I haven't used the calibration service yet.

Talking about the 100-400, has anybody ever sent the 100-400 back to Canon service for problems with locking function? I can't lock it anymore which is a bit annoying. Does anybody know how much it costs to repair it (just a guess in the right direction)?
