Sigma 150-600 Sports

I got one not long after it came out and it takes great quality photos (for a zoom lens). Despite being water resistant, mine did eventually let water in, which wouldn't dry out and eventually mould set in. But, it served me well for a number of years. Build quality was good and it survived numerous bangs and drops (including a drop which totally smashed my Nikon D800!)

Excellent review Tord S Eriksson.

Hi Tord,
An excellent review!
This lens is so good but as you say heavy! To resolve the hand holding problem which I like to do from time to time, especially when capturing birds in flight I purchased the Contemporary Version too. I believe that this lens is every bit as good. Clean sharp images! I think its only pixel peepers that can tell any difference, if there is any!
