Some people say the zoom will creep out if you tilt it down, but I'm not having that issue so far, seems pretty stiff.

I even tried explaining that other people had this problem earlier in the year, but to no avail

As with most lenses, there are some reviews about it being soft or people having issues with it, but just with my initial tests outdoors and on kids, it produces some really sharp images, and I believe (haven't confirmed since I just purchased it), that the markiii has some built in compensation for it at the wide end

Some people overlook this lens for the fact that it is a "kit lens

Many people are undecided whether they should get a 24-105mm (around $700), or they should buy a 24-70mm a f/4($1500), or even f/2.8 ($2300)

If you want to buy canon lens, definitely go to L series lens which guarantee great image quality, especially this 24-105

(24-70L - look, I'm talking about taking the photo gear along with all that stuff small children need, or the mothers think they need ;) or were them not very versatile (the fifties) or the quality felt bellow the expectation (28-105 and the cheap kit lens).After shooting with this not so well regarded 24-105 L I must say it was exactly what I needed: delivers high IQ pictures with strong contrast and yes, it can blur the background enough for most cases - at least for portraits shot at 3 to 4 meters alway

I was pleased with this older lens and held off buying the more expensive 'L' cause I didn't think it could be that much of an improvement.

The 24-105 L IS seemed like a good replacement: it got good reviews, has more reach, AND it has IS

Almost bought the shorter, faster L series but glad I went with this one.

Why, I compared this to my only other Canon's Zoom lens --70-200mm F4 L, which is also the cheapest 'L' lens from Canon

L would be perfect for the 7D.

I looked for other options and this damn L lens just kept on popping in my mind

suite for everything, very sharp, very fast, great L series lenses. f4 at 105 looks stuning, the macro also is very decent.

Solid L Construction*

, 70-200 F4L IS + 1.4xII (all Canon)Apart from the Luxurious L mechanicals and feel, the IS and focus seems to be top notch

An awesome "L" series lens

the only down side of this lens is that i dont get to use any of my other fancy L lenses

I've seen many reviews heaping praise on the Canon 24-105 f/4 L, and I'll just add to it.

After I started using it I noticed a HUGE difference in the quality of photos after switching to this lense, and now I refuse to buy anything but these beautiful L series lenses

Outstanding L lens.

My EF-S 15-85mm lens delivers a similar FOV for APS-C, has better IQ, and it doesn't even carry the renowned "L" designation

This lens has been great and if you are in the market for a high quality lens in this Focal length, spend a little more and get the L series like this if you can

A compact L standard IS zoom that is an excellent walkabout lens

I am already eyeing 17-40 f/4 and even worse, 14mm L

The zoom range, from medium wide-angle to medium telephoto, certainly makes this one of Canon's most versatile "L" series lenses

I was a little bit surprised to find the first lens I really wanted to get back was not of the more expensive L lenses, but this one

It's one of the most versatile L lenses and is very useful for different situations

I go with fast non-L primes, 28F2.8, 50F1.4 and 85F1.8
