The lower edges are indeed terrible...but the image is also very soft throughout the frame, even at the centre. Was the camera hand-held or on a tripod?

This has been discussed extensively here. The 3x will not focus at the shortest focal length setting. You can verify this easily by zooming out to 10 mm, focusing on something and then resetting the zoom the the shortest F.L. The image will be out of focus. As you rotate the focus ring to bring it in it won't go quite far enough. Many people have reported this problem. I can't recall anyone having reported it fixed. If it is fixable I'd love to have it done.

MTF edge testing confirms that this lens is as sharp as the lens than Canon ships with the XL-H1 at its long setting but is appreciably blurrier at its shortest focal length which is, of course, the focal length we all bought the thing for.

thanks for your replies. if i remember correctly, i just couldn't get focus for this particular shot. maybe because this scene was artificially lit & my iris was wide open? it is on a tripod.

here is the reverse using the 20x lens:

another shot with the 3x that seems in focus but with the edge blurred specially the left side, fstop 1.8:

3x lens at least fstop 5.6. looks ok

matthew, it's a church in the province. i forget the name. it didn't look that good because they painted the walls green. the warm light offsets it

3X zoom failure

Dave
I had the same problem with my 3X zoom last year. See my thread that I posted. A PCB had expired, which was changed by one of their service centres here in the UK. I was surprised at how quickly the lens was turned round. I think they must have had a supply of these boards. I did expect to have to wait a few weeks. It could be a weak point. I also find it odd that you must power down the camera before a lens change. I can change lenses on my EOS1D digital SLR powered up so why can't I do the same on the XL2? I think the auto-focus could be better, mines goes out of focus as soon as you hit the zoom switch, then comes back in.

3x lens malfunction

hello,
just got back from a 3 week trip to nepal. all went fine and the camera (xl2) held up excellent, except the 3x lens...
the first 2 days in kathmandu all equipment worked fine. the third day in the morning i changed to the 3x lens (i used it the day before as well), it said "check lens" in the view finder. i did. and then it worked for a few minutes. after that it started having its own will! after 6-7 sec of turning on the camera, the lens either went out of focus, black or totally overexposed (bright as the sun). the zoom didn't work from either manual or camera controlled. about 25% of the times i turned it on it stayed good.
i'm kinda hoping that it could be something that i can fix myself but doubt that.
it's still under warranty (bougth at bh)
anyone have any ides? anyone had similiar probs with their 3x?
should i just send it back!?
all the equipment is transported very carefully in a semihard camera pack.
appreciate any help
thanks

Is it possible you took the lens off wihtout powering down? You can blow a fuse in the lens if you do this! check the lens on another body first. Maybe at the store.

This sounds like an intermittent contact either inside the lens or on the external contacts. Is the lens working better since you returned? These contact issues can somtimes be the result of the climate you are operating in.

sometimes the zoom work for about 3-4 sec. stops working and the screen goes out of focus. nothing works and then after tunring it off and then on again it sometimes work or it's still out of focus.

Hi Thomas,
I know exactly what you're talking about. The same thing happend to me. I have never changed lenses without powering down, even still... my 3x lens died on me at the beginning of a shoot. I don't know what I could have done to prevent it... so it scares me to think it could happen again at any time.

hi Webb,
what did you do? did you send it back? did the warranty cover it?
yeah, i know. its scary. first i was really worried that it was the camera, then i would have been screwed... everything else works fine on the camera.

I just got MY 3x lens back from Canon New Jersey for the T H I R D T I M E!!!!
Each time it stopped zooming and focusing. I've only had the thing for a little over a year. I'd call it the "L" word, but am scared to jinx it, and hope that this fix works.( last time it took a shite on me in the middle of a fashion shoot).
Canon...can you say "Deseign flaw"? How about "quality control"?

Hi Thomas,
The lens was only a few months old, so I sent it to Canon repair in CA. Turn-around was about a week. I dont' know if it helped, but i mentioned in my notes that I use this lens to make my living so a quick turnaround would be appreciated.

To add to the @#$%-factor of the whole situation, when I got the lens back the back-focus was out, so I couldn't get anything to focus. Well, another $25 in shipping charges and another week or so later, I finally had my lens back and (crosses fingers) have not had problems with it since.

Bruce - I totally agree, I think Canon either has a design flaw and/or a QC problem. It's one thing for the lens to be bad, but for the service department to fix one problem and create another was unacceptable. Oh well.

I don't like to throw stones at anyone, including Canon. I can say from previous threads on this forum only and not from personal experience that the New Jersey repair center seems to have a better track record on fixing it right the first time. Luckily, I haven't needed their services yet.

regards,
