Customer Ratings & Reviews

Purchased this lens to improve the quality of my photography and videos after researching and learning that this is one of the best lens in the industry. I got to say that this lens will do more for improving your quality than upgrading to a new camera body. You will be blown away by the sharpness and it will take your cameras photos from basic to professional quality instantly as long as you focus them right. The focus ring is very smooth, but Auto focus is a bit spotty in video sometimes still works well in single point modes though. The lens is huge and heavy though so make sure your using it on a body than can support it or get something to balance it if your using it on a smaller body camera. Overall very happy with this lens, it has a nice wide focal range from 18 to 35 on the wide end and it stays at a constant 1.8 to keep that crispy bokeh background blur. Know what your getting with this lens though, it will be great for portrait photos, objects where you want to blur the background, great for low light photography or video as well, and has a very short minimum focus distance meaning you can shoot extreme close ups of things. It will not be good for street photography as its too heavy, it wont zoom very far, and it wont be the best lens for personal travel. This is your professional workhorse lens, and it won't disappoint! Thanks Sigma for making my camera that much better! I use this on a Canon 80D and also on a Lumix G7 with an EF adapter. Good luck deciding if it is right for you I hope this helped you out!

Excellent video quality at f1.8 and up. Super smooth zoom ring and easy to manually focus. Potentially takes extremely sharp images, if the focus is correct, and that is a big if. Unfortunately this needs a lot of work with micro adjustments to properly auto focus. Which means you MUST buy the Sigma Dock to calibrate it, otherwise you will be lucky to get a sharp image using auto focus. At least for Canon apparently. I'm using then T7i, and out of the box this lens was horrible while using the auto focus. Luckily it was mostly fixable, now I get sharp images using the auto focus, however it still doesn't pick up obvious subjects in the frame sometimes vs a Canon lens does almost 99% of the time. So once you get past that and accept it, this lens is amazing! Great in low light, obviously with the f1.8, but an f1.8 at 18mm. Excellent for filming or photos indoors, razor sharp when the focus is hit, and worst case, use the manual focus. I tried the manual focus and found that it was not only really fun, but really easy. So I take one star away because of the focal issues, but every other way this lens is supurb.

I own the T7i and have only used Canon lenses up to this point. They've been fanstatic with auto focusing for video and photo, and this Sigma was way off out of the box. Way, way off. I had no chance for an in focus photo. Video was ok, the dual pixel worked ok, but not great. Against Canon lenses it was pretty bad, but usable. I had to purchase the Sigma usb dock, had no choice. Spent 8 hours over 2 days calibrating it. It definitely got much better, but still off a lot of times, but now its usable for photography, so I'm cautiously optimistic that I will be able to fix it completely and be able to take amazingly sharp photos. But by no means am I happy with the amount of time I had to put into fixing something that should be fixed before it's shipped out. My advice to Sigma would be to scrap this lens and rebuild it to work with the newer model cameras.
