Reliable product for all occasions, quality on par.

I tried out three different lenses while I was in the shop. One of them had a front focus, and the other two ended up being really good overall. A very good lens for the price of 16,000, which is the price of the version without image stabilization. For 22022 rub. Since the absence of a stub is not at all important at focal lengths ranging from 17-50 millimeters, I do not believe that it is reasonable to purchase a version that includes an image stabilizer. It sounds more like a tactic that Tamron would use for marketing. You could purchase a Tokina AT-X 165 f/2.8 Pro DX for the same amount of money. It is optically no better than the Tamron SP AF 17-50mm f/2.8, and in certain places it is even less crisp when the aperture is wide open, but it has a pleasing "plastic" picture and a superb branded metal construction, which makes it liquid in the secondary market. Unlike Tamron, which, after a couple of years of operation, can only be sold for a penny when it's put up for sale. In a nutshell, it was not an honor for me to purchase this lens.

Pros

Above f/4, there is a crispness that is really nice. Included around the outside of the picture's frame as well. Even though it "cools" a little bit on D300s with automatic BB, the color rendition does not seem to be the source of any particular concerns. When viewed from broad angles, vignetting and distortion do not appear to be overly distracting (for a third-party product, of course). Unbelievably light and diminutive (making it suitable for young women who are on the thinner side). Since this was my first experience with the Tamron image stabilization system (VC), all I have to use as a benchmark is Nikon's (VR) technology. I did not notice a significant change, other from perhaps a slightly more "twitchy" performance from Tamron's stub. I did not notice any other changes.

Cons

Inadequate construction. The hood need to be handled with the care that one would a crystal vase. Chromatic aberrations that are particularly severe in the focal length range of 17 to 20. Does not like backlight (although, to be fair, it should be noted that all lenses in this price range do not like brightness, thus this statement is not unique to this lens). The price in 2022 was no longer appealing due to the fact that the lens now had a stub attached to it. Sometimes the autofocus will be blurry.
