On paper, Sigma's decision to release two 150-600mm zoom lenses at the same time is an odd one. Both cover a zoom range that appeals to wildlife and sports shooters, but when you use the Sigma 150-600mm F5-6.3 DG OS HSM Sports ($1,999) and the 150-600mm F5-6.3 DG OS HSM Contemporary , the...

Expensive; Very heavy; Relatively narrow aperture

Specification Over the past year or so, Sigma has been gradually updating their lens lineup to fit into one of three categories, Art, Contemporary and Sports. This super-telephoto zoom lens fits into Sigma's 'Sports' line-up of lenses that promise excellent optical quality, fast autofocus and a dust...

While the focal length range of this lens immediately raises the eyebrows of wildlife and sports photographers, this lens is not limited to those uses. While photographers pursuing other subjects may not immediately recognize the usefulness of a 150-600mm zoom lens, many will quickly realize the...

I use this lens on both Nikon D500 and D850 bodies. The lens has a great build and is weather proof (I've had the opportunity to test that). The autofocus on these cameras is great with this lens and I could ask no more of a lens in terms of sharpness and general acutance.

This is the lens I decided to purchase, after having tried Nikon's new 200-500. There is a lot to like, not least its fast focusing (which you can set to even faster if you need it, or slower, more precise if you want that instead.

Lovely sharpness; fast focusing; water-resistant

Weight; and the fact that the weigh moves forward as you zoom out

It's a BIG lens... not for the faint of heart. Takes great pictures. Not quite as good as a $10k lens from Canon, but not much off of it either. I highly recommend it.

So how do we call the thing ? Sigzilla is taken so Sigsaurus maybe ? Seriously, the Sigma 150-600mm f/5-6.3 DG OS | Sports is QUITE a lens so I'd like to start the verdict with a warning.

Excellent sharpness; Low CA; Well built; Fast focusing; Keenly priced; Dust and moisture resistant construction; Effective stabilisation; Focuses relatively close for a 600mm lens

Zoom creeps forward when pointed downwards (without lock engaged

Loving this lens so far. I have put up a full review with a bunch of sample images of Australian wildlife.. Enjoy :) http://www.davidromaphotography.com/blog/2014/12/sigma-150-600mm-f5-6-3-dg-os-hsm-sport---australian-hands-on-review-with-sample-shots

Excellent build quality, 600mm wide open is very sharp even handheld; stabilization is quite effective, I quite like the push pull

It is rather large and heavy; But that is to be expected at 600mm and I was able to hand hold it with no issues; The minimum focus distance leaves a bit to be desired when compared to the Canon 100-400mm

Ordered this at 11:00 Sunday and took delivery at 14:00 Monday, great service from WEX. Did an all day bird shoot on Tuesday, the lens performed very well. Liked the quality feel. Focused very quickly and accurately on my Canon 6D.

Durable; Quick Focus; Sharp Focus; Strong Construction
