Excellent product for my entry level experience with photography, will put it in good use pretty soon on my trip to NY.

This lens is a great addition to my bag. I take a lot of hockey pictures and this lens is fast enough to catch the action and the zoom cuts down on lens changes from wide to tele.

It's a good one! Mounted my new Sigma 244-105 f4 ART on my new Nikon D750 the day I received it and captured a few subset images and out again 1st thing the following morning for fall color at a near by lake lined on two sides with Cottonwood trees many of which were in full bloom. Post processing yielded some of the shots this year. I please with this lens, fast focus, great build quality, and most off all image quality. This lens is tack sharp.

I use this lens on a Sony A7RII and really like it. I’ve only had this for a short period, but it is as sharp as the Sony 24-105 f4 and cheaper. I’ve found I prefer the contrast and color of this lens more than my Sony lenses. Downside is that it’s a touch soft at f4 in the corners and focusing isn’t as fast as the Sony. But the sharpness in the middle and stopped down to 5.6 is great. I had the Sony 24-70 f4 and hated it. Borrowed a friends Sony 24-105 until I was able to test the sigma and am glad I got this.

Purchased this lens last year along with a Canon 6D Mark II. It has been my go-to lens for this last year providing some great shots. Highly recommend it as an option to more expensive options.

This is a fantastic Portrait and Landscape lens! A great walk around do anything lens! The clarity is wonderful from edge to edge!! Beats the heck out of the nIkon 24/120 and costs less too! You won't be disappointed!! Thanks B&H :)

I am just getting to know this lens, and I think for the kind of images I make this lens is perfect, not only for its range, but also for its ability to work the extremes and produce images that are great to work with in post production. I am excited about the journey in really getting to know this lens.

This is a really good lens for the price, considering that it takes super sharp pictures throughout the zoom range especially in the center-but if you want sharper corners wide open, I found turning lens aberration corrections OFF on the Canon version helped a lot. Autofocus is also thankfully accurate on my copy. The caveat? This lens is pretty heavy and dense compared to the Canon 24-105 L which I tried alongside the Sigma. If you can deal with the heft, this lens is truly great value for money.

I have had this lens since Jan. 2017. I use it with Sigma's MC-11 adapter on my Sony A7R2 and love it. It has seen thousands of shots in all conditions here and in Europe and has become my carry-around favorite. Sharp, fast focus and solidly built. Easily outperforms my similar Canon lens I had for my 5D before I switched to Sony. And it is $300 less expensive than the new Sony version. I am an award-winning photojournalist of 40 years and my gear must perform in all weather and hold up to my use. The Sigma Art series lenses I have, 20mm F1.4; 85mm F1.4, this 24-105 F4, and the Sigma Contemporary series 150-600 f5.6-6.3 are tough, sharp, fast focusing, low distortion and every bit as good for high-megapixel cameras as the best of Canon, Sony and Nikon. I do have some Sony G-master lenses too, but my Sigmas are easily their equal.

Love the range of this lens, and the sharpness is great.
