Great Daily/Travel lens
The Tamron 28-200mm f/2.8-5.6 Di III RXD is a fantastic all-in-one zoom lens that has become a staple in my camera bag. Its versatility, image quality, and affordability make it a great choice for photographers of all levels.The 28-200mm focal length range covers a wide variety of shooting scenarios, from landscapes to portraits and wildlife. The f/2.8 maximum aperture at the wide end allows for beautiful bokeh and low-light shooting. Despite its impressive zoom range, the lens is surprisingly compact and lightweight, making it easy to carry around. The built-in image stabilization helps to reduce camera shake, especially at longer focal lengths.Compared to other lenses with similar focal lengths, the Tamron 28-200mm offers excellent value for money.The lens produces sharp, detailed images across the entire zoom range. The colors are vibrant, and the contrast is excellent. The autofocus is fast and accurate, even in low-light conditions. It’s great for capturing fast-moving subjects. The lens feels well-constructed and durable. It’s weather-sealed, making it suitable for outdoor shooting in various conditions.Overall, the Tamron 28-200mm f/2.8-5.6 Di III RXD is a highly recommended lens that offers exceptional value and versatility. It’s a great choice for anyone looking for a single lens that can handle a wide range of shooting scenarios.

Incredibly Versatile Travel Lens
This lens is incredibly versatile and exceedingly high quality for the price, and I fell in love with it after one rental.It’s perfect for travel, as you get a full 28-200mm range (and can easily crop in to 400mm equivalent on a high-resolution body (see my attached bird in bush picture). No more fumbling with lenses as your kids run ahead and your spouse taps their foot; you can cover pretty much everything with just a flick of your wrist. It even handles semi-macro well (see attached bee photo).Typically superzooms trade off sharpness and maximum aperture for their versatility, but this lens instead narrows its range by 4mm to maintain both a wider F2.8-F5.6 aperture and outstanding center sharpness. Be aware that this lens does not feature stabilization and is best used with a camera that has in-body image stabilization. That said, the brighter apertures of this lens allow you to compensate with faster shutter speeds as well.Overall I would strongly recommend this lens to anyone who is looking for a first or travel lens for an A7X body, as it is a jack-of-all-trades for a very reasonable price.

Versatile, but auto focus is disappointing
Overall, this is a fine all-around lens, especially if you’re traveling, a beginner and/or on a budget. With that said, the auto focus capabilities leave much to be desired.I’ve been using this Tamron lens on an a7iii for the past 15 months or so. It was a long overdue replacement to the kit lens and an old telephoto a-mount lens I was using. The 28-200mm focal range covers a large area and is very appealing. The lens is not overly heavy or large, making it great for traveling. For many photographers, this can be a decent all-around lens, limiting how many lenses you have to carry. It is an upgrade from the kit lens in most areas.I primarily shoot landscapes and storms. When I first used this lens, I thought I was doing something wrong. The auto focus was very slow, sometimes not able to focus at all. After several months of use and research, I’ve accepted that it’s just not very good with auto focus. I’ve tried every focusing mode imaginable and upgraded firmware. Maybe the a7iii body is part of the limitation, but I think it’s largely the lens itself.When I’m storm chasing, I need a quick and accurate focus, especially when there’s a tornado. These phenomena rarely last longer than a few minutes, so every second counts. It seems like auto focus with this lens is good with close or “obvious” subjects, but I cannot get it to consistently lock in on clouds and other distant objects, even when zoomed in and on a tripod.On the bright side, I was pleasantly surprised at how this lens performed for the April 2024 solar eclipse. With a filter, zoomed in to 200mm (NO teleconverter), manual focus and using the a7iii, I had low expectations. I was able to capture multiple solar prominences and had shots that I’m proud of, after some modest editing.I definitely have mixed feelings on this lens. It does outperform the kit lens with clarity. The extra reach is great, but the auto focus is no better than the kit lens. For the first few months of use, I forced myself to stick to this lens to get comfortable with it and the focusing still disappoints me.I later upgraded to the 16-35mm GMii lens and that lens is in a whole different league. For most landscapes and storm chasing, I need the wider angles anyway. The native 16-35mm rarely leaves my camera, outside of portrait shoots. I’m just disappointed that if there’s a tornado on the horizon, I can’t switch to the Tamron lens to zoom in with any confidence. I recently had another storm chase with a tornado last week and I needed the extra zoom. Auto focus wouldn’t work with this lens and I quickly snapped to manual focus, but due to time constraints, I was shooting handheld and didn’t get the best focus before the tornado dissipated.Honestly, prior to the eclipse, I was ready to give this lens away. I was surprised at how this lens handled that event, even at 200mm with a filter. That performance won me back, but then recent tornado events reminded me about how bad this lens can be with auto focus.I am planning on upgrading camera bodies in 2025, probably the a7Rv, so I am curious to see how this lens handles in that case. I’ll update this review once that happens and I’ve had some time to play with it.

A lente é boa, atendeu minhas expectativas. Uma lente com ótimo custo x benefício.

I like it so much! Ver useful an convenient for travel.
