Should I keep my 35mm F2

This really isn't something that has caused me a problem on this lens. Yes it is louder than USM lenses, but "loud?" no. It is just a buzz which is very short in duration as the af is pretty quick.

It's a good lens, worth the money with very good IQ. Just not sure how much use it is going to get alongside the 17-55 f2.8.

I suppose another way of phrasing the same question is if you already had the 17-55 f2.8 would you then go and buy the 35 f2 as well.
