I'd also like to point out that the 24-70 f4 IS price tanked in very few years, this lens segment is well saturated. Canon would have to put out a very improved lens at a very affordable price to get people to upgrade from either the 24-105 or the 24-70 f4 IS. I don't see this type of lens being on any of Canon's short lists for 'refresh'. Maybe this will change if the 5DIV has a 30+mpix sensor and thus an IQ improvement will be in greater demand.ahsanford said:Antono Refa said:Canon has a long history of making kit lenses starting with 28mm and ending at 80, 90, 105, and 135mm.

I understand that, but Nikon's 24-120 shows exactly why you don't offer that lens at an L (or equivalent) level:
24mm: http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=733
120mm: http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=733&Camera=614&Sample=0&FLI=6&API=0&LensComp=0&CameraComp=0&SampleComp=0&FLIComp=0&APIComp=0
At 5x, the wheels tend to come off the bus optically. To my knowledge, only the 100-400 II does a good job of a large FL multiple. There are some fans of the 70-300L as well. But a 5x zoom lens for > $1,000 seems like money poorly spent unless you are comically strapped for space, are in a terrible environment to change out lenses (rain forest? desert?) or are principally shooting video.
This is why I agree with Canon on the 24-105 moving downmarket to non-L, STM, variable aperture territory.

Given a choice of either the 24-105mm f4L IS USM or the 24-70mm f4L IS USM I would take the 24-105. The 24-70mm f4L IS USM I have a. exhibits image shift b. Is soft from 45-65mm until you stop down to around f8. It does control CAs better but its no way good enough for the 5DS. By comparison my copy of the 24-105mm is no softer & has better reach (Ive tested both in controlled conditions using the CIPA resolution chart & an even field illumination sphere)jd7 said:Between the 24-70L IS and the 24-105L IS, the way I see it is:
Advantages of the 24-70L IS:
Better IQ - sharper across whole frame (I feel that is the case with my 24-70L IS v the 24-105Ls I have used, and it seems to be borne out by Lens Rentals resolution tests), less distortion (esp at wide angles), less CA, better flare resistance / contrast shooting into a light source
Faster T stop
Lighter
Smaller
Macro mode (albeit only really for casual macro use)
More modern IS system
Zoom lock (OK it's not very significant! I like it when hiking though.)
Advantages of the 24-105L IS:
It does 71-105
I can understand, though, why that single advantage of the 24-105L is enough reason for some to prefer that lens! (It has occurred to me I might be better of with the 24-105L, but I don't think I will go that way.)
I would be interested in a 24105L IS II though. While I actually do quite like the macro mode on the 24-70L IS, I would trade it and the size/weight difference for the extra reach if it otherwise had the advantages of the 24-70L listed above (if that's possible).

Rob Carter said:In the days of high usable ISO I would think a target to aim for will be a wider zoom range, lower weight and smaller aperture.
Smart phone cameras are a fixed focal length, no manual controls, jpg only, etc, hardly comparable with DSLR kits. If your main concern is weight rather than the countless advantages of good glass and DSLR then, by all means use your iPhone... There is little to no room to make a brick of glass any lighter.Rob Carter said:I cannot stress too strongly about weight reduction. With claims of DSLR quality from an Apple phones I can see why more and more people are not carrying a ‘brick’ around. For my leisure time I go walking, where at one time I would see a lot of DSLR cameras on the fells and peaks I no longer see them. Everybody uses their camera phone.
A situation that Canon must be well aware of but unable to effectively do anything about.
