Thanks!

I just bought Canon 10-22 and I am looking for the "all the time on the lens"

filter for it.

Hoya Pro1 filter has 3mm ring and front threads.

Can anybody tell me if there are any problems with putting standard Canon lens

cap on the front thread of the filter?

I doubt that photographing cities you can live with shallow depth of field that large apertures (like 1.4 for instance) will give you. That tells me that you will not avoid a tripod. Keep your lenses and buy a tripod - that would be my advice - sorry to disappoint.

I totally agree with Ken. You can get 20D with kit lens for almost the same price as 20D body. After using it for a month you will know what you need (wider? longer? faster? sharper?). If you decide that kit lens is not for you, you can always sell it on eBay.

Photozone site [http://www.photozone.de/8Reviews] is a good source of information about lens tests.

Kevin,

The aperture @ 18 mm does not matter. What does matter for autofocus is how bright the lens is at given focal length. If the lens at given focal length is not bright enough to autofocus it will not autofocus. The lens will not go back to 18 mm in order to autofocus @ 200 mm.

Be aware that with focal lengts where this lens is aboove 5.6 (therefore close to 200 mm) 350D or any other Canon DSLR will not autofocus. The lens must be at most 5.6 to allow camera to autofocus.

Funny thing is that one of the pictures on the first page of default view (currenlty #2) is Critique Only photo!

I had to answer the same question some time ago and I went for 17-40. It is a better lens optically then 17-85 no doubt about it. I don�t use it with monopod since I don�t even have any but I am sure that it will work great in that combination. Personally I don�t mind carrying tripod. It works pretty well handheld in some situations too. By the way - I don�t think you will be able to handhold 17-85 IS @ 1/4 - at best results will be inconsistent. I am saying that since I�ve tried it with my 28-135IS to handhold it @ 1/8 � 1/16 and only about 25% of the images taken at about 28 mm were keepers. So you will not probably get away with just the IS if 1/4 is the goal, and you will need some camera support anyway.
