Hi Andre, This is a tough one, I don't think I would like to part with
either lens now. I have said previously that I bought the 28-135 as a
temporary measure when I switched to Canon and was waiting on delivery of my
L lenses, I liked it so much that I decided to keep it. I must add too that
I have not enlarged or compared similar images from both lens in an attempt
to compare sharpness. They are both capable of producing very sharp images
and I have submitted trannies from both lenses which have been successfully
published in glossy colour magazines (half page, full page, and double page
spreads). When I am on assignment shooting details shots and statics I
normally use the 28-70, probably because it is there and I *assume* that if
one is sharper it would be this lens. I also like it for occassional
portraits which I shoot at f2.8 for background effect. The other advantage
for me using this lens is when I can't get back far enough from the vehicles
that I am tracking/panning for action shots. I have been able to shoot with
the 28-70L on AF and it actually tracks fairly well for a short zoom -
definitely faster than the 28-135.
The main advantage with the 28-135 is the lighter weight and particularly,
focal length (although I agree that 24 -120 would be nice). It has great
optical qualities for a lens in this price range. There is no aspect of this
lens that I have found I dislike and I have taken some great pan shots of my
kids on their bmx bicycles etc, using AF.
There is no deciding which is the better lens, they are both great. You
decide which suits your application/budget best. If I gave up shooting
professionally I would most likely sell all but the 28-135IS and 20/2.8, and
buy a 100-400IS. Although I haven't used the 100-400 myself it would make a
superb all-purpose kit and all reports on this list seem favourable.
Yikes! what a long post - but you asked. I hope it helps.
Regards, Tim
