>Canon 20mm lens I've never owned the Sigma, so I can't speak to that. I do own the Canon 20mm and when I was making the decision between zoom and 20mm prime, I went with the prime and haven't regretted it since, even though I have strong preference for zooms.
>Secondly - IS. I've been a bit alarmed about people saying their 28-135 ?IS has been making 'funny' noises! Is it the general opinion that this >is due to a design flaw, poor assembly In my opinion, this issue gets magnified on the list. I bought a used 28-135 IS and have never had a problem. There are scratchy noises sometimes when the IS is engaged, there is zoom creep when the lens is pointed downward, and the viewfinder does jerk at times when panning. The IS is not nearly as silent as on the big glass 300,400 etc... but it is still IS and the lens is quite sharp enough for the kind of needs I have. I had a 28-70L but I sold that off because the trade-off in sharpness and f/2.8 wasn't enough for me to abandon my IS. Plus, for the price of the L zoom I could replace my IS zoom several times. >Next filters. I'm also going to be buying UV screw in filters for all >the lenses. However, for the 20mm would it be a good idea to shell out >the extra to get a multicoated filter (it's 82mm so that's �62 for a >Hoya SMC)? Or should I just be removing it to take pictures anyway? Yes and yes. I buy the most expensive multi-coated filters I can afford, with the intention of taking it off when I take the photo. However, real world shooting means that I only get the filter off about less than 1/3 the time. So despite all the arguments, I keep the filter on because I know how clumsy I am.
