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

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

After reading and watching reviews, I decided to buy to replace an aging 70-300mm nikon lens as wanted the extra reach. There's a good array of feature considering it's in the entry category of lenses. 3 focus settings plus 3 Optical stabilising settings and the option for programming user settings.

Build quality is superb, and image quality is excellent. It is much sharper than the Tamron 150-600mm which I have subsequently sold, as the Sigma is clearly a better lens than the Tamron in every way, most importantly in outright image quality.

On opening the item i was suprised to find it comes with it's very own well padded carry case, Barrel lens hood and rubber cover to replace the tripod mount when removed, The lens is quite heavy so a tripod is a must for prolonged use.

This is a very popular lens for our bird photographers, although it is not for the faint hearted and you will need to consider a tripod/monopod.

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

The Sigma 150-600mm f/5-6.3 DG OS HSM Contemporary lens offers very similar image quality to the Sports version at a cheaper price, whilst being much lighter and therefore more suitable for hand-holding, although it doens't feature the same level of weather-proofing.
