Offering the unique mixture of an all-in-one zoom range and a fast design, the 28-200mm f/2.8-5.6 Di III RXD from Tamron is a wide-to-super-tele zoom distinguished by its bright f/2.8 maximum aperture at the wide end of the zoom, along with its sleek and portable design. A series of specialized elements are used to maintain high sharpness and clarity throughout the zoom range. Benefitting the optical design is an RXD stepping motor, which enables quick, near-silent autofocus performance to suit stills and video, along with full-time manual focus override and a minimum focusing distance of 7.5". Suiting this lens's use in harsh climates, it also sports a moisture-resistant construction along with a fluorine-coated front element to protect against fingerprints and smudging.

Tamron 28-200mm f/2.8-5.6 Di III RXD Reviews
Best Single Telephoto For Sony Full-Frame
I recently bought a Sony A7Riv and thought the Sony 24-240 telephoto would work great with it. I already had the Sony lens and had been using it on a Sony A6000 for a few years. My photography is varied -- from skateboard videos to travel photography to nature stills. Using the 24-240 on a better camera revealed its shortcomings. I could not get a tack-sharp photo no matter what I tried. Tripod, remote, manual focus, setting adjustments and more -- nothing worked. There are higher quality Sony telephoto lenses but none that cover most of this range with a single lens. I don't mind carrying two lenses for travel, but it's a deal-breaker for video. After doing my research I decided to try the Tamron 28-200 and it's a very big improvement. I can obtain much better sharpness. Even videos look a bit crisper and can tolerate more cropping. Losing a bit of the wide end (from 24 to 28mm) has been a price worth paying. PROs (compared to Sony 24-240): significantly sharper; slightly lighter in weight; slightly less expensive; works almost seamlessly with the A7Riv. CONs: loss of the 24-28mm range; a tiny bit slower in focusing initially -- this hasn't been a problem for the type of photo/video I do, and continuous focus works well. I was going to sell the Sony 24-240 to B&H's used department, but it's value on the secondary market is low. I'm giving it to my son who has a Sony a6400.
Super versatile with great image quality
This lens should be everyone's must have. It is by far the most versatile sony E mount lens in the market. Only wishes are: 1. it would be better if it starts at 24 instead of 28 2. larger aperture (I may be too greedy)
Great lens for the price. Sharp throughout its zoom range.
A great value in a wide range zoom
While I have only had the lens for a few weeks, it hasn't been off the camera since I got it. Its range covers almost anything I'd do albeit not with same level of quality that my 20mm f1.8 and 85mm f1.8 G lenses perhaps but I'm hard pressed to see any real differences. While my others lenses would be used for specific occasions, this lens is the best travel option for the money. For that reason alone, I would recommend it to any one in the market for such a lens.
Perfect travel lens
I rented this lens and the Tamron 18-300 prior to purchasing this 28-200. This lens is fantastic! I wanted one lens for when I travel and this lens fits the bill. I thought the 18-300 would but it was a little too big and the images from 300mm were not sharp. The images from the 28-200 are sharp across all focal lengths. Check out some of my sample images. Zoom in on the lighthouse top and you will see the woman's should er tattoo. And then check out the details of the eyes on the girl with the hat.
A super value all in one lens for the Sony E Mount
This lens has an excellent focal length range with a wide f stop at the low end (28 mm) and more than adequate f stop at the high end (200 mm). My wife and I are using this lens on a Sony A7IV, Sony A7c and Sony A7RIVa and we find it to be an ideal carry around lens to which we default when we are not doing 'serious' or more focused photography (pun intended). It is light, relatively compact and well made with some weather resistance and takes a standard 67mm filter (which appears to be Tamron's standard for their Sony E Mount lenses). Auto focus is excellent and very responsive and matches most of their constant f/stop lenses for the Sony E Mount. Results are remarkable for a lens of this focal length range and cost. Slight softness at the edges is just noticeable at the long end of the range but this does not detract from the tac sharp focus image in the center throughout the focal length range. f/5.6 may seem a little dim at the long end of the range (200 mm) but I find myself using this even on lenses that claim f/2.8 just to get the depth of field, so in practice this reduction in light at the long end is not a problem. f/2.8 at the wide end is great as you are more likely to be inside a building trying to get a shot while close to the subject where the wide is most useful and the light level lower. The only criticism of this lens is that the wide end is limited to 28 mm and not the more usual 24 mm. However, the consequences of trying to achieve this would be a lens that was bulkier and more costly as you have more work to do to correct speherical aberration and pin cushion or barrel distortion at the wide end. Overall a superb addition to our lenses for the Sony camera and well worth the money. The slight trade off in image quality is more than compensated for by the fact that this is the lens you are more likely to have mounted and available for that shot which occurs at a time when you do not have time to swap out the lens for a higher quality but more restricted focal length range lens.
I love it
After research, it is exceptionally sharp and has a nice focal range.
