I have a similar question. Some people argue that a UV can protect the lens and some others that putting anything in front of your lens knocks points off performance. I've read stories that people had focusing problems with certain UV filters. I recently got the Sigma 70-200 /2.8 HSM and thinking wether i should use a UV. At the moment i don't;but i'm using the hood that came with it for protection as well. But still i'm uncomfortable when handling with the thought that front element mayu be scratched or when i have to clean it to gewt the dust off i scratch it by cleaning it or something like that. Has anybody solid experience of a decent quality (Hoya,Sigma or BW) (multicoated?) filter causing any focusing problems or image quality degradation ? thanks, Konstantinos * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
