Its pretty good...The images that I took are sharp...this Lens is very wide. GOod for landscape as well as some daily portrait...
It's a great len with nice shots. However, a little bit heavy to carry with big size. Reasonable for its cost.
Great for cameras with built in focus motors
The product is great because it has a very wide aperture for a zoom lens, without breaking the budget! It's also a constant f/2.8, so you have great aperture even when fully zoomed in. However, unless you have a focus motor in your camera (the D3100, D5100 and their successors do not), you cannot use autofocus on the lens. It doesn't have an autofocus motor built in.
"This lens is F***ing amazing!"
My girlfriend purchased this for her Nikon D5200 camera. To quote her exact words: "This lens is F***ing amazing!". It has a slightly wider angle lens, so it is great at taking indoor and outdoor photos. It lets in a LOT of light, so it also great for low-light photos, including cloudy or overcast outdoor shots. We are very happy with this lens!
This is a great lens much cheaper and much lighter/smaller than the Nikon version. Pictures are very sharp especially stopped down a little but F2.8 is still very usable. A great replacement for Nikons 18-55 F5.6.
