As it has been mentioned in number of reviews all over internet the lens proves its abilities without iota of doubt. Here are my observations about the lens which has been used for 24 hours since purchase. 1. Silent focusing motor.

While it may not be obvious from the charts, the Sigma 150-600mm f/5-6.3 DG OS HSM Contemporary surprised us in a positive way - at least when taking its comparatively low price tag into account. Yhe lens is generally capable of delivering a good to very good quality in the image center.

It is a great lens I have used it for taking pictures for a ballet dance performance, the fast and quiet auto focus and the sharpness give me a great impression to looking for more sigma lens.

This lens from Sigma's Contemporary range is lighter and more compact than the Sports version, and is more affordable too. It's available for Nikon, Canon and Sigma bodies and works with both full-frame and APS-C DSLRs.

I haven't fully used it, yet. I did try to capture an eagle and got nothing but blur. Perhaps operator error. Still working out the kinks.

I am extremely happy with lens. I have taken practice shots and the photos are outstanding. I love it!

I can't begin to brag about enough about this lens. I bought the Canon EF version and use it with the Sigma MC-11 Adapter on my Sony A6300. Great AF and Stability Control performance.

Bought lens for canon 70d. The sigma lens was a great addition.

JUST GOT THE LENS...SET IT UP ON TRI-POD IN STUDIO..TEST SHOTS IN ALL MM RANGE..SHOOTING MANUAL .. NOT RAW FILES, BUT 24.MEG FINE...SO FAR SO GOOD..LENS LOOKS TO BE WELL MADE..FEELS GOOD IN HAND...i find it interesting the spec sheet says DO NOT USE VIB-REDUC IF MOUNTED ON TRI-POD..

This one I bought it from snap real after lot of research and comparing prices at various portals I am very satisfied with the product and fast delivery
