20x zoom lens -- various topics

Ron German · July 10th, 2005, 07:55 AM

Thank you Jay and Ash
As I said, the camera`s owner was not familiar with it.
But Is there a need to do a back focus adjustment or hearing the click sound when fitting the zoom is enough?

On the auto lens there is no back-focus available to the user, it must be done at the factory. Have you tried it a couple times? I have noticed it happen on my XL1s from time to time but it always seems to correct itself with a re-mount.

No Ash
I had the camera on my hands for few minutes and when I found this big lens problem (after zooming in and out many times) I gave up testing the camera.

i noticed that i can gradually turn the ND filter so that i can get in between settings from no ND to N32. i did not, however shoot with these in-between settings because they might have had bad effects. Are there any bad effects? Image wise? would it damage the lens when kept in an in between position?

thanks

I tried it once and got some weird effects. I would not recommend it. Part of the image was blurry and part wasn't. Something just looked weird. I can't imagine it would hurt anything but it could ruin a shot since it is possible that part of the frame is covered by one ND filter and the other part covered by another. I doubt it is a subtle gradient transition between these 2 degrees.

i would suspect something like this. could you link to a vidcap? i'll try to do some testing if i can because if it works, then it's a great thing to use

Hi everyone,

Which of these cir-polarizing work better on the 20x

B+W or Hoya.

I need it for sunny days and shooting the clouds.

Thank you

Hi,

I started out looking at the Hoya but I found a used B+W so I bought it.
The lens guy that I purchased it from said that Hoya and B+W are on par with each other = excellent.

Either will work just fine...

Anyone know where I can purchase extra dust caps for the 20x lens and camera body when you take off the lens for transport?

I can't find this part anywhere. Can only find the 72mm cap that goes up front.

Thanks.

Greg Boston · October 25th, 2005, 06:04 PM

You may have to actually call Canon to get the parts. They have many parts available through phone sales that aren't listed online anywhere. Case in point, I just bought a replacement lens hood and zoom lever pin for the 16x manual lens.

I believe it's 1-800-OKCANON. Follow the wonderful menu trail from there. They are very helpful once you get to talk to someone.

I know it's probably too soon to tell, but would there be any advantage whatsoever to use the H1 HD lens on an XL2?

A. J. deLange · November 15th, 2005, 10:55 AM

Definitely yes because it has to be a better lens to support the higher resolution of the new chip set. What is not so definite is that it will be appreciably or even noticeably better.

Peter Sheppard · November 18th, 2005, 02:12 PM

Received my XL2 last week and same night went out to shoot traffic scenes for part of a TV spot. This was the first time I used the camera and the new Florite 20x Lens.(Ive used Xl1 and 1s for years.) I was surprised by the tiny floating lights when shooting into approaching cars. Every headlight it seems produced several "floters" that were very annoying, and distracting. I have not seen this before with the 16x lens on the XL1s....is this a new feature ??? I took off the tiffen UV filter, but it made no difference....any comments would be welcome.

Chris Hurd · November 18th, 2005, 02:50 PM

This artifact could be caused by image stabilisation. Turn OIS off and see if there's a difference.
