Canon lens question and thoughts on EOS 1000D?

Hey all,

was reading this review;

http://www.dpreview.com/lensreviews/canon_18-55_3p5-5p6_is_c16/



And was wondering if anyone here would be able to tell me what they mean when they say the following;

The filter thread is 58mm and rotates on focusing, which can be a pain for filter users.

Rotating front element a pain for filter users

On my current lens (Olympus) I always have a UV filter screwed on and 90% of the time use a lens hood aswell. How do they mean by the rotating element being a pain for filter users? Anyone any idea?



EDIT:

Also, I was wondering what peoples thoughts are on the Canon EOS 1000D?

Some filters such as a circular polariser consist of two sections the outer plane is rotated to achieve the required effect.

So the last thing you want is the outer element of the lens rotating when you have already rotated the filter to the desired angle.

I suppose a Canon 1000d , 500d are entry level

the 30, 40, 50d ones would be Semi Pro

and the 1d 5d ones would be considered pro.

Ah, you got in before the edit Mr. Glas.


I see the issue with the ciruclar polarising lens alright.. but would a UV be OK? I generally use a filter to just try to avoid the actual lens getting dirty/damaged...

It won't affect normal filters like a UV filter but if you use any graduated filters, polarizing filters or if you fit a filter holder like a Cokin, then it will be a major pain in the butt. As you focus the filter will turn as it's attached to the end of the lens (which turns while focusing). You don't want your filters turning askew after you've composed your shot.
