Hard to tell for sure, but since the 18-135mm actually has the words "Nano USM" written on it, and these ones don't, I'm guessing they have the good ol' regular USM. Not that that's a bad thing, although I was really impressed with the focusing speed on that 18-135mm, and it would have made sense to find it at least on the new 24-105mm.

The UWA lenses do extend with zooming, they just do so with an inner barrel behind the filter thread (which is why those lenses require a front filter to complete the weather sealing). If you look at the zoom mechanism, they're actually most extended at the ends of the zoom, and most retracted in the middle (the lens has to get longer as it gets more retrofocal).
As to why the 24-xxx zooms can't zoom internally, the answer is that they could be made that way, but would you really want them to always be the extended length (or slightly longer)? Personally, I'm glad that Canon designs them with a shorter collapsed length. For example, compare the non-extending 70-200/4 IS with the extending 70-300L – the latter has a 50% longer FL, but is shorter when retracted. That is why the 70-300L is my preferred travel telezoom, it fits vertically in a camera bag slot, rather than needing to lay flat and take up two lens compartments.

Hey docsmith
What's your opinion on IS for shorter focal lengths? When does one want IS and when is it sufficient to work with a faster shutterspeed?
At least with my copy and level of caffeination, I have consistently good images @ 16 mm and 1/4" shutterspeeds, mixed results at 1/2" and occasionally a hand held shot up to 1". So it definitely works, but may be more of a 2-3 stop advantage.

I Eagerly await some reviews!

Ebrahim Saadawi said:I've been using the 24-105mm F/4 L IS as a video lens for ages and it's just a workhorse of a lens. This lens has been a de-facto standard for video shooters on the 5D series era and on the C100/C300 as an all rounder ''doc'' lens.
Mine lived on my 5DII and 60D (great range for both sensor sizes from wide to tele) and the lens alone carried my video production company, it's specifically ultimately exceptional in video Image Stabilisation unlike any other Canon lens, but sadly one time the tripod fell off and the hit was right to the extended lens barrel. It was stuck/fixed, seemed like something easy to fix, but I found out it was officially dead and repair exceeds the cost of a new one. So it lives now as room decoration.
Since I moved from Full Frame video and lost the 24-105mm. I found an alternative in the absolutely brilliant Canon 18-135mm IS. It's only APS-C (so only 60D, C100, C300, not 5D, which I sold and it got outdated in the video world).
And I found that little gem to be better in every single way including image quality except for build quality/feel and constant f/4 aperture.
But the 24-105mm wasn't ACTUALLY a constant aperture lens, it got darker whilst zooming during video, not much different from the variable 18-135mm oddly. So that was a strange downside with the lens, I thought I was the only one with a bad copy but it turns out this was documented and reported by all video shooters.
The 18-135mm has a larger range and wider for APS-C (which is the standard for video/cinema), less distortion at 24mm, similar/identical sharpness, same overall image, slightly better image stabilisation, silent AF and IS and Iris, and smaller/lighter weight and cost.
The 24-105mm has Full frame coverage shall you need it, constant f/4, and L series build quality, for a very low price point.
I'd ditch the 18-135mm and get this new lens if it has a few things. Most importantly, image quality. The 24-105mm and 18-135mm are great lenses and do very good 2mp 1080p video, but when you pop on a Canon 50mm f/1.8 and look at the image both set at f/4, it just hits you how much POP and cleaner colour and 3d dimension feel these primes have. This aesthetic is in the Canon 70-200mm f/2.8 II IS and 24-70mm F/2.8. One might think that at at 1080p HD the resolution increase in the lens wouldn't show up but it does, significantly.
So for me it needs to be:
1- Sharper. Higher resolution. Just get more of that POP it lacks compared to primes and other L glass.
2- Less Distortion at wide shots. It's hideous. In photography you can correct it but in video, not so much.
3- Doesn't ramp aperture/transmission while zooming from 24mm to 105mm like a normal constant should.
awinphoto said:Fair enough, however i've always found the extended barrel tends to be one of the weakest points on the lens, as a working professional photographer... i've had to send my lens in before because while walking from location to location at a shoot, the barrel self extended and then an unfortunate knock screwed up the zoom ring so it could not fully zoom in or out and had to be repaired. At the very least, i hope they put a zoom lock on this lens.

The leaked images seem to indicate it will have a zoom lock. The 70-300L has one, it's a bit annoying becuase the reverse-mounted hood blocks the zoom lock, but that won't be the case with the shallow hood for the 24-105L II.
