Even though a lot of people on youtube seem to think this lens is 'meh', there's a lot to like about this lens. The images I get from it are very sharp, the zoom range is very nice for super-35 format sensors, it features a constant aperature, and it feels like a great quality build. The feature I wasn't expecting is that the internal volume of this lens doesn't change when zooming or focusing. That's really important when you work in a cold environment and then bring the camera somewhere warm as it reduces the chances of condensation on the internal elements of the lens. I really wish more manufacturers provided that as a feature. Overall, a great lens. Now if I could just get it with an RF mount...

Bought this lens for a trip to shoot water falls in Michigan's Upper Peninsula. Amazing image quality and versatility. For the price, you're getting an extremely solid lens with beautiful quality, fast focusing, sharp and easy to read values. It's weight is much lighter than I was expecting; much lighter than my prime cinema lenses of similar size (which is good if you are already lugging a big camera around on hiking trails and climbing a million steps). Highly recommended. Sigma knows how to build a lens!

This is the best lense that i have ever buy. Tye photos are very sharp and clean and i like that the fish eye view on the photo is very minimum when you edit the photo. SO FAR THE BEST LENSE THAT I EVER BOUGHT. EVERY PHOTOGRAPHER DEFINITELY NEED THIS LENSE ON THEY BACKPACK. Thanks B&H for having Sigma products on they store.

I normally shoot wildlife with a 100-500mm but I needed a portrait lens for the r7 and have been wanting a wide angle lens as well. This checks both boxes and combined with the IBIS on the r7, Christmas portraits and my landscape photos are razor sharp! F1.8 also means great low light images and beautiful backgrounds. After seeing the image quality from this lens, I now have my eye on the Sigma 50-100 to fill in the focal gap. I haven’t tried video yet, but I hear it’s amazing as well. Excellent investment if you’re using aps-c for a fraction of the cost of a professional series prime. It’s like having a bag full of primes in just one lens!

This lens quality look extremely amazing, just want to know if I need an adapter when combining it with the Sony A6300

I bought this 4 years ago and I still use this Sigma the most often. Whenever I go on trips and can only manage to bring one lens with my BMPCC 4k or 6k, I always grab this one. Especially love this in tight spaces.

The image quality out of this lens is amazing, great focal range, great bokeh and a nice, constant wide aperture. This is a very good lens for covering events, protest, direct actions, etc.

It is bulky and heavy, but that's just a limitation of physics.

We are using this lens on a Black Magic Design Studio Cam (older model) with a metabones adaptor, and it works beautifully. The low light application is great.

This is one of the better entry lenses. Awesome price, great focal length for cropped sensors.
My major complaint is just that it isn't the sharpest lens, even when shooting at higher apertures. (4, 5.6, etc).
But it works really well for what it is, very worth the money.

An impressively sharp lens with accurate autofocus. I use this lens on a canon r7 with the canon ef to rf adapter, and the autofocus is quiet, accurate, and fast. Great results, and excellent bokeh/depth of field. A very reasonably priced lens with features and quality that rivals lenses many times the price. One of the best options for those looking for a high quality image and professional results, at an affordable price point. Minimal softness at the edges, especially when stopped to F 2.8 or F 4. As I had heard in many online reviews before my purchase, the advantages of stepping down the aperture past F 8 - F 11 or so are somewhat limited. This lens performs best between F 2.8 and 5.6 for most close to medium range shots. That being said, it still offers nice bokeh and good image quality at fully open aperture of the advertised F 1.8. I have heard criticism that it does not perhaps have quite as much of the “3D pop” of other lenses with similarly low aperture numbers, but I haven’t found myself wanting when shooting with this lens. If I want that kind of character, I tend towards my cinema and vintage lenses when that extreme depth of field is more central to the presentation. This isn’t to say that it doesn’t possess the ability to offer those characteristics, just that I find it’s hard to replicate the undeniable qualities of a vintage canon 50mm 1.8, or a similar (or much wider) focal length cinema lens. These lenses are sought after and are frequently used for good reason. This lens is great for both photography and video, and offers a great balance of features (such as autofocus) that many vintage and manual cinema lenses just can’t offer. This is a great focal length for portraiture, street photography, highly detailed close focus nature photography, and close to mid range video shooting. This easily performs as well as updated autofocus systems, even when using an adapter for use on newer camera bodies
