I Purchased this recently, great service.

I purchased this telephoto lens, and tried it out ! it definitely handle the job for shooting wildlife and racing cars on the track ! If you don't concern about its weight, you should rock this lens ! Why strongely recommend this lens come on !

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.

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.

THIS IS BRILLIANT, I'M A SPORTS PHOTOGRAPHER OF 27 YEARS AND THIS LENS ON MY 5D MKIII IS AS GOOD AS MY COLLEAGUES 100-400 MK II AND 400MM,500MM AND 600MM I'M NOT KIDDING, IT'S REALLY QUICK,FOLLOW FOCUSES WITHOUT LOSING THE SUBJECT IT'S SO CLEAR AND CRISP,IT'S QUITE HEAVY, BUT I LIKE THAT EVEN ON ISO...

Durable; FAST AF,SUPER SHARP,GREAT COLOURS AND CLARITY; Great Features; Great Picture Quality; Simple Controls

NONE

A fine high value zoom lens. Stabilisation was a problem until I used the Sigma dock and put the OS into the Dynamic mode setting - magic, then it's as good as most Canons' IS. I would assess the Sigma 150-600 C OS benefit as 3.5 stops.

Still decently sharp at 600mm (F8-F11) Autofocus works well on 6D Excellently sharp between 150mm to 430mm Really gives the Canon 400mm F5.6 L a run for the money at 400mm

None at price point (A bit soft in the corners at 600mm FF; but hey its as good as the Canon EF 400mm F5.6 L which has no IS and about costs about the same and better the Tamron 150-600mm at 600mm

Rented for 4 days from Lensrental.com, $67.91, shot lots of hiking/wildlife/nature/zoo pix, almost all hand-held (on Canon 70D). I'm no bodybuilder but had no problem with weight - when walking the support came from my Kinesis (kgear.com) chest-worn holster, ideal for support and quick-draw action...

Quick focus; portability; sharpness; colors; stabilizer

Manual focus ring too stiff; stabilizer drifts off focus point

The Sigma 150-600mm f/5-6.3 DG OS HSM Contemporary ($1,089) is a big, heavy lens. But that's no surprise when you consider its maximum reach, full-frame sensor coverage, and sturdy build.

Excellent telephoto reach; Very sharp; Includes tripod collar and lens hood; Focuses quickly; Effective image stabilization system; Zoom locking mechanism; Affordable

Some chromatic aberration; Moderate pincushion distortion; Relatively narrow aperture; Heavy; Not fully dust- and splash-proof

Although Tamron pioneered the release of the first 150-600mm lens, Sigma followed suit by releasing two versions of lenses with exactly the same focal length and aperture ranges.

If you spend a lot of time photographing wildlife, sports, aircraft in flight (or even UFO's) I'm sure you've longed for a lens with extreme telephoto reach. Sigma now offers a tough, quality 150-600mm f/5-6.3 DG OS HSM Sports lens that can fulfill the wishes of many nature and action shooters.
