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).

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

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

Pros:- reach light weight effective VC decent IQ price Cons:- Have to use f/8 to get decent sharpness at 600mm Not a replacement for 600mm f/4

I just made my first purchase from Ritz, a 150-600 Tamron Lens. It's a spectacular piece of equipment. It was competitively priced and was delivered in a matter of days. If you are thinking about making a purchase I say, "go ahead and do it."

Dollar for dollar this is a hard lens to beat. Good sharpness and contrast. One of the best lens purchases I've ever made. Really should be a lens any serious photographer should own, unless you can afford the big bucks on the Nikon or Canon glass. For the size of the lens its not too heavy.

Light weight for what it is; Fairly sharp; Good contrast; Zoom range

Can take multiple twists to reach focus when manually focusing
