After driving myself nuts with reviews of all the big zooms, this was on sale for $800.00. Talk about bang for your buck.. Very, very sharp, I think at all focal lengths. Great VR, some vr jump after the shot, but ok... easy to hand hold with the tripod collar on & it makes a great carry handle...

I did quite a bit of research on this lens and competitors lenses in this price range, The Tamron 150-600 is very popular, and I can certainly see why. I consider myself to be an enthusiast level photographer.

This is a very good quality.lens., It is light weight for a 600mm telephoto, Auto focusing is fast, faster than I expected; This lens is very capable of producing sharp pictures; Great price for a lens with this kind of capability and quality.

This lens meets or exceeds my expectations; So I can't complain; No Cons!

I've only owned this lens for a week, but I've waited 7 months for it to ship after pre-ordering, so I thought I'd get some info out to you sooner rather then later. This lens pairs extremely well with my Nikon D7100 and is sharp to 500mm wide-open (well f/6 anyhow at 500mm).

Consistent Output; Durable; Easily Interchangeable; Fast / accurate auto-focus; Rugged; Strong Construction

Heavy

My first good impressions were its size and weight which are smaller than what I thought; it is good!! Put it on my Nikon D850 and took it out to a park; I like its sharpness and AF accuracy, again beyond my expectation. Only had it for two weeks and so far I am very impressed and happy.

great for nature photography.

Durable; Easily Interchangeable

I just got this lens and was messing about in the yard. I was probably 40 feet from this leaf, at full extension. I'm pleased with the image quality. It's a heavy beast, though! Camera used was a Nikon D7200, 1/1250 second at f/8, 1600 ISO.

I recently purchased this lens and used it almost exclusively during a stay of a week on an island photographing all manner of seabirds including the ubiquitous Puffin; for the price I paid the lens was outstanding producing sharp and detailed images sometimes at great range.

Durable; Great Features; Great Picture Quality; Simple Controls

I needed a telephoto lens for a pending holiday in the Highlands of Scotland, my camera is a Canon 7D. I had already bought a 2 times converter as I could not afford a dedicated Canon tele lens but wasn't satisfied with the quality or resolution.

Love it. Swapped for 100-400, which I loved, but added zoom makes this purchase a no brainer

Zoom range; Image quality; Value for money

Cannot think off any
