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
Great value for the price
You really can't beat this lens for the price. It is a little slow, but in general works great, good range, good zoom, and picture clarity is top-notch.
Great photos! A little slow
Has a good f2.8 that gives me great light on 28mm on 200mm goes with f5.6 that is also good. Kind of slow on the autofocus but if your not in a hurry I think it covers my needs. When I say slow it's compared to my Sony 24-70mm Zeiss lens. All my tests are made with a Sony Alpha 7 IV
Great All-Around Lens
I wanted a lens for my Sony a7RIV for trips where weight is an issue. I am heading to Central America, and I don't want to take a lot of lenses and I really don't want to change lenses in this environment. The 28-200 meets my needs for trips like this and is quite sharp and lightweight.
So Versatile!
I do a lot of hiking and nature photography. Carrying multiple lenses can make my pack really heavy. This lens allows me to take moderate wide-angle shots but still be able to zoom into details. It is also a great lens for traveling. To capture wildlife I can use it in super-35 or clear-image-zoom mode to get the equivalent field of view of a 300 to 400mm lens. I use this lens most often with my a7c for a lightweight but powerful kit but I also use it frequently with my a7iv. It is so versatile that it is on my camera more often than any other lens. The 2.8 aperture at 28mm is a neat "trick" adding to the versatility in low-light situations. The image quality is not g-master quality but still excellent. I have noticed some color fringing but that is easily corrected in post. At this price point you simply can't go wrong with the Tamron 28-200.
Finally an All-In-One with good optics
This lens serves my purpose when I'm traveling and when I am just walking about not knowing what interesting subjects and scenes will be encountered. I had been carrying an a7Riv with the Tamron 2.8/70-180 in the belt pack of a Think Tank Rotation 22 plus a Fuji x100v on a neck strap. That is good, but this is 800g lighter while a larger focal length range. I'm sacrificing wider apertures which I rarely want in the field. For travel I will combine this with either my Sony 4/16-35 PZ G or my Loxia 21. I always want a hood, for both blocking of stray light and for front element protection. But I also want quick access to my CPL. Therefore I use collapsible rubber hoods and attach my CPL (and my NDs) to the hood's front threads. Below 35mm on this and on many zooms the deep frame of a collapsible hood will vignette. By stepping up to 77mm on this lens I can shoot at 28mm without vignetting, if I leave the hood collapsed, and the frame of the hood does function a bit to block stray light. For convenience I use only K&F magnetic filters and tethered pinch caps. I sold my heavier Sony 4/24-105, bought from B&H in 2018. I cannot think of any circumstance in which I'd choose the 24-105 over this lens, advantages of much longer reach, faster aperture in mid range, and 75g less to carry. Any time I want to go wider than 28 I also need wider than 24.
LOVE IT - my all around lens
Great lens for multiple uses and when you can only carry one. It's very responsive and I am very happy with Tamron. I just wish they made prime lenses with wide apertures.
Nice All in One Lens for Sony E-Mount
I researched the Tamron 28-200 and many reviews highly recommended it as the best All in One lens for the Sony Full Frame mirrorless system. Have not traveled with it yet but I did test it out and it works well.
Blurry, bad focus interaction with Sony bodies
I have now bought and returned two of these. Both had serious image sharpness issues. Both were unable to obtain a sharp image at any focal length, even when manually focused. The second was better, but still inadequate, especially at longer focal lengths. I considered attempting a third copy of the lens, but I give up, I will just buy the Sony lens.
