Having read all the professional reviews on various photographic websites I decided to take the plunge and invest in, what most of them described as a superb all rounder lens and I am so glad I did.
From the moment you un-box the lens and attach it to your DSLR, you know that you have got a premium quality lens to work with, it has a very solid feel to it. The lockable lens hood is a great touch, especially for those who lose them regularly. The permanently attached tripod foot and lens collar that will fit into any arca swiss tripod head clamp is a very useful addition to this lens as it negates having to use a L-bracket to change your camera format from landscape to portrait.
Using the lens for the first time was an instant hit, the focusing is super fast and very accurate, even in low light situations, the lens optical stabilisation works perfectly and allows for hand-held shots at least 3-4 stops less than normal.
The images produced by using this outstanding lens are punchy with excellent contrast and captured superb fine detail, even more so if used with an high megapixel DLSR such as a Nikon D850.
Sharpness is brilliant throughout the whole image, from F2.8- F11 , the results will deliver first class pictures, obviously depending on subject matter and photographers requirements.
The lens can be fine tuned to the users taste, such as focus limiting to certain lengths, different optical stabilisation options dependant on use and the lens software can also be updated using a sigma lens dock.
The only very minor negative would be that it is an heavy lens, weighing just short of 4lbs, but that is to be expected of a lens that is packed with expensive top quality glass.
I would thoroughly recommend this lens to any serious photographer whatever genre they specialise in, it is a top allrounder
