I know you won't be having this for sport, but still 5.6 on the tele end is just too bad. Isn't F5.6 the lowest value where Canon can do the autofocus? So if it would be half F worse, this lens wouldn't be able to autofocus at 85mm. I know it's not important, it's just a visualization of how bad 5.6 is. I would really like to see some test photos at 5.6 @ 85mm anyway, because I think that they might not be the best. We all know that usually best photos are at apertures a couple of stops slower than fastest. F5.6 might be too limiting even for everyday use.
I am looking at this lens as an alternative, EF-S 17-85mm f/4-5.6 Image Stabilized USM.
