As meantioned in the description Wonderful all round lens with excellent low light imaging.

Fits the bill as the perfect walk around lens for my 77D. Image quality is very good with nice color rendition and weighs half as much as the 24-105 f/4L. If you shoot both full frame and crop sensor I say get this lens for your crop sensor camera and leave your 24-105 f/4L on you full frame camera.

Hands down best lens for the money. While it's not Nikkor, it is also not over $1k. When my original lens broke after 4 years of abuse (I live in East Africa) I replaced it with a different Sigma. After not getting the same quality shots I bought this one again.

I bought it used at 211 pounds and for that price the lens is superb. The quality of the image is great and focus perfect & fast on my Nikon D7500. Much sharper than my old Nikon 16-85mm lens.

I've seen the review here which mentions Chromatic Aberration / Purple Fringing being not too well-controlled, but try as I might, I am unable to make this lens produce significant visible evidence of CA . I'm testing it on an EOS 80D, shooting RAW, Adobe Color Space.

Convenient focal-length range for a go-to carry-everywhere lens; Excellent sharpness throughout, Well-controlled CA, Silky feel to the zoom ring, No front-element rotation during A/F, Looks great, Light and compact, but not too light

No manual-focus over-ride; Focus ring rotates during A/F

I purchased this lens to replace my standard kit lens that was originally included when I purchased my camera. I can say that after testing the new lens that I am well impressed by the build quality and the resolution of the pictures that are sharp in colour and clarity.
