The IS works wonderful and I am always told how clear my photos are by others.

Properly used, it offers perfectly clear and tack sharp photos at very high resolutions.

I take photos for our local museum and the lens works perfect.

It is HEAVY (about 2 lb), but I immediately noticed how sharp these photos were, compared to my EF 18-55mm lens that came with my Canon Rebel XTi

"All I want is good photos" lens.

With this L quality glass, I can crop the photo and usually find the photo still looks amazing.

the photos still came out blurry...and much profanity was uttered

I was amazed of how sharp the photos are zoomed in at the maximum in the Digital Photo Professional (DPP).This is my favorite lense for everyday walk-around use.

But never fear, the Eos 5D Mk II comes with Canon's Digital Photo Professional that corrects this problemo.

Overall this lens is fantastic: it is tough, very good photo quality and the focal length is good for many applications

This lens takes great quality photos and is my daytime/outdoor performer

I can get better photos from a high end point and shoot camera for 2/3 the price.

This lens is instead a close-focusing zoom that will let you take good photos of single flowers, but not get down inside to register tight images of pistils and stamens except with the largest blooms

Despite all the technical metrics, the real measure of a lens boils down to the subjective question: does it take good photos?

This lens is pretty awesome, the photos are super amazing for someone with zero photography skills

And yes, awesome photos in all light conditions

The photos are FANTASTIC, the noise is almost none-existing, unbelievable

This lens is perfect for someone who wants good quality photo and sharpness but not the difficulty in focusing

For the price and build quality, this thing is perfect!I mostly use this lens as a general purpose as is but when I'm indoors I always shoot with my 430EXII flash to keep that sharp crystal clear photo I love

The USM motor is really nice and quiet and the photos are great and clear

Despite all the technical metrics, the real measure of a lens boils down to the subjective question: does it take good photos?

Someone wrote that the photos are less sharp when shooting at f4.

I was shocked at just how lousy the photos looked

I feel like this lens gives the most versatility for someone who wants amazing photos and also wants to shoot occasional handheld videos.

I have had photos published in the LA Times, and other nationally distributed magazines, and that lens took photos worthy of publication

The constant aperture along with DSLR's improved ability with high ISO's allows many great photos in low-light that were previously impossible

The zooming is smooth and the photos are sharp

This lens has the optical quality of the shorter zooms and the range provides enough opportunities to capture many great photos.

This lens produces very sharp photos

It was a lens that took very good photos at times but it had some real limitations.

The image stabilizer performs well too, and I was able to get acceptably sharp photos at 24mm down to 1/5".

Every photo from every canon and sigma lens I've used looked like photos taken with a nice DSLR

The EF 24-105L not only takes good photos, it takes beautiful ones, notably nicer than several other well-regarded lenses in the same price range

Altough it is not a huge deal, 4.0 and 2.8 is pretty much different if you prefer indoor photo

It's a great size with very sharp photos!

While I've gotten some great photos out of the 24-105, I also have the 100mm f/2.8L macro (which I highly, highly recommend!), and the IQ of the macro lens is clearly superior with shots taken with the same settings (aperature, shutter, 100mm, etc.).

I realy like this glass, good photo quality

The image-stabilization really works and allows sharp photos of stationary or slow moving subjects to be taken in the same light as an f1.4 lens

The short: The 24-105 turned out warmer, more beautiful photos in both indoor and outdoor usage, capturing vibrant, accurate colors.

Great photos with my 7 D Mark II.I love

and the photos just looked like snapshots

So, I wondered how much better I could make my photos if I *did* know what I was doing

Better kit does produce better photos, even if you don't know what you're doing

It gives me excellent photo quality

I recently used it at a wedding anniversary and the couple loved their photos
