Let's us do just that.
So go return the 24-105mm. Where is your wide angle man!

Yes. USM gives you smoother, faster, more accurate focusing. It's also quieter. But the reason I love it is that it (almost always) means full-time manual focus (FTM); something I frequently use when composing certain types of shots as I can tweak the focus after auto focusing (don't even think of trying this with non-USM lenses!).Does it matter that is lacks USM?

I have two non-USM lenses that both fill a certain niche, but in general if I'm paying serious money for glass I want USM -- and FTM - in the bargain. YMMV.
Rereading the thread, I guess I must've missed where you actually addressed USM. Maybe it was in one of your snarky comments, making it easy to overlook?
To the second point that you brought up, whether it matters that the 18-135 IS lacks USM, my point was that it does to some of us.
Apparently, you think only your opinion matters? Or maybe you are having a bad day and are taking it out on the entire thread? Who knows?
You mean one of those comments that was mistaken to be a snarky comment perhaps? I'm also well aware USM it matters to some people, it matters to me, but I don't see you recognising that USM wasn't an issue for the person who started the thread, hence the reason why I suggested it in the first place. I don't care whether you need it or not, this isn't about you dude.
You clearly don't, you're second guessing at this point and you're not that perceptive.
There are some L lenses with USM that lack FTM, e. g. the 85 mm f/1.2.If I'm buying an L lens, I fully expect USM with full time manual focus. Some lens have USM, but don't give you full time manual focus.

To my knowledge they're based on an older design. Newer USM L lenses all have FTM.Why do you think that is OreoCookie? I didn't even realise.
I thought you were referring to non-L lenses in your post....I just said that.

Which is why I brought it up.If I'm buying an L lens, I fully expect USM with full time manual focus. Some lens have USM, but don't give you full time manual focus.
