I'm looking for a 70-200 f2,8 (IS or not)

It's the 1st time I see a 70-200 f2,8 L IS without tripod colar on it and i noticed a lot of screws on it ! Is that normal ???

Is the without IS version the same ?

Those are the little bosses that engage the tripod collar. All lenses that use that collar have them.

That's perfectly normal.

The screws hold a small bushing which allows the lens to revolve in its tripod mount.

OK thanks, but this awful and doesn't look like a "pro" built quality IMO

Then keep the tripod ring attached and you will never see them

Really?

screws = manly
screws = tough
screws = rawr
screws = Frankenstein, who had a rather high build quality for its time

:D ?

Have you seen the new Pentax available with the all white body? There is also a limited time available Nikon D60 with gold accents. Both look totally bitchin'.:D

The only time I notice the studs on my 70-200 is when I am trying to line them up with the tripod collar to put it on the lens.

Why, they are not screws, they are bearings, And without them and a lens of this design, you would have to either fatten up the area by the lensmount, or live with the tripod ring almost falling off if you loosened it up too much if they weren't there :)
They also make the lens turn much smoother when loose and under weight

The old 80-200mm majic drain pipe does not have these screws.

So if you bang your pro lens on a table corner, and the zoom unit or IS unit gets broken... how the heck is Canon supposed to dismantle it in order to change parts if it weren't for those screws? :) I don't get it. By your definition, if it has screws it's not so pro? It's a big complex lens and apparently designers found that those on the mount weren't enough to hold everything.

No i just critisize appearing screws, not the one in white color IN the lens on the body lens. On others 70-200, there is not such screws, not on f4L already
