I just did a search to see what has bin posted on the lens and now that it has bin out for a bit and many of you own it is it worth owning? Do you use this focal length a lot? I find that on all the longer zooms I have had over the years most shoots are take at the long end of the tele lenses. Like my 100-300mm most shoots, 98% are at 200-300mm range almost never at the 100mm. I fear if I spent the money on the 35-100 it would only be used at 100mm and also I don't like the 75mm focal length so that lens is out. And with the 100-300mm I have a 100mm but not a fast 100mm.
