Just bought a 24-105mm L IS USM F/4 white box ... I was kind of surprised that the zoom feature had an articulating/moving front element .. Is that a particular version (date) of the lens or do they all have that feature? My other L lenses do not have that zoom 'part' ..

thanks in advance.

Are you saying if you put a polarizer on the view would change after zooming? I have that lens and the front element does not rotate. The lens physically moves outward, but the front doesn't rotate.

Or are you comparing it to the 70-200 which does not zoom outward?

Correct - like the 70-200 that does NOT zoom outward ... that was my point ... thanks for verifying !

Mine does extend also when it is zoomed.

All of the 24-105's extend when zooming and the 70-200's are internal zoom.

A majority of lenses do this when zoomed. Only a few like the 70-200's keep the same length. Also it's pretty sad you have that much money invested in camera equipment but you apparently don't even do enough research on a lens before you buy it to determine if the barrel extends while zooming.

I don't want to sound mean, but it is a little true.:rolleyes:

@Raylon - whatEver .. As it turns out, I *DID* have this lens a few months back - borrowed for a trip and loved the shots .. but brain cells being what they are for SOME people, I couldn't recall that the zoom element actually extended ... so I simply was asking the more friendlies here a simple question ... and WHERE in specs for a lens does it state the "zoom element articulates" or not? huh ?

The 24-105 is my default lens.
Doesn't really matter if it extends or not, you would have still bought it.
It's a good unit. Have fun.

I wasn't trying to sound mean, just pointing out an interesting little thing I noticed. A simple search on google yielded me multiple reviews from several sites that showed the lens zoomed at both extremes, showing the full length of the extension. Also Canon's site states that zooming makes the barrel extend 32.5mm.

OK, I was gonna poke some fun- decided not to. But I did get a laugh out of it. Actually, I can understand your concern, especially if you bought used, for instance. And it's not like Canon stamps "Mark I" on the first version or something similar.

Question to the OP: Why do you still have a DC ( Sigma equivalent to EF-S ) lens with only a full frame camera ?

I have a 10-20 DC Sigma that works fine starting at around 17mm. He has an 18-50 so it may work fine. IDK...

I don't use mine on my FF though. It works lovely on my 40D though. :)
