Tamron 28-200mm F/2.8-5.6 Di III RXD Super Zoom Lens Review

The Tamron 28-200mm f2.8-5.6 Di III RXD is a superzoom lens that is compatible with mirrorless cameras that use the Sony E-mount. It has the potential to produce seriously high-end image quality and performance in all aspects, while still maintaining a tiny, lightweight, and travel-friendly construction.

However, such objectives are not simple to accomplish. It’s common knowledge that superzoom lenses may be both excellent and harmful. One of the advantages of using them is that they provide you with a strong zoom range that ranges from wide-angle coverage to powerful telephoto reach. As a result, you do not have to change the lens that is attached to your camera.

The negative aspect is that the overall image quality is usually reduced, particularly in terms of uneven barrel distortion at short zoom settings, which is difficult to fix, and poor sharpness at the long end of the zoom range.

On the other hand, Tamron is the kind of company that might make a respectable superzoom. The firm has a rich and famous history of making superzoom lenses, extending back to the period of 35mm film, and it has poured all of its skill into creating this 28-200mm. This lens has a focal range that extends from 28 to 200 millimeters.

Design & Handling

It’s great to have the rock-solid build quality, but it shouldn’t come at the sacrifice of increased weight, especially for a lens that’s supposed to be used for traveling. The Tamron achieves an excellent balance thanks to the combination of its high-quality metal mounting plate and durable plastic barrel construction. It has a sturdy and well-engineered feel about it, yet despite its light weight and manageability, it is still rather durable.

The structure incorporates weather seals, and the front element features a fluorine coating that not only makes it easy to wipe clean but also repels moisture and oil. Although the lens includes a zoom lock function to prevent the inner barrel from stretching while you are moving around, our test sample did not experience any zoom creep in any way.

The action of the zoom ring is silky smooth, and the electrically connected focus ring provides excellent precision. The handling is sophisticated. The host camera body is the only location from which aperture changes may be made.

Performance

Superzoom lenses, as we mentioned at the beginning of this discussion, often offer a great deal of versatility as a result of the wide range of focal lengths that they include, but at the expense of an overall reduction in picture quality. The sacrifice brought about by using this Tamron is kept to an absolute minimum by the lens. Impressive levels of sharpness may be seen across the entirety of the zoom range and throughout the entire image frame.

Also, distortions are handled considerably more effectively than they are in the majority of superzoom lenses. Indeed, the Canon RF 24-240mm is almost worthless if one does not rely on the adjustments that are made in-camera.

The Tamron lens performs considerably more admirably, exhibiting very little barrel distortion even at its less wide-angle minimum focal length of 28 millimeters, as well as pincushion that is mostly under control in the 50-200 millimeter region of the zoom range. There is the possibility of almost eliminating any appearance of distortion thanks to automatic adjustments that may be made in-camera.

Color fringing is almost nonexistent in the image’s middle region, and it is only discernible at the image’s extreme peripheries, particularly its corners and edges. To reiterate, though, automated in-camera fixes are possible to get rid of this issue.

Conclusion

This Tamron lens checks all the necessary boxes for a convenient superzoom to take on the road. It has a small footprint, is not overly heavy, and is resistant to adverse weather conditions. The lens has refined handling, a quick and precise autofocus mechanism, and an aperture rating that is quite fast, all of which contribute to the lens’s all-around flexibility.

The image quality is quite remarkable for a superzoom lens; this is helped by the rather moderate total zoom range, which doesn’t push the envelope at either end of the zoom spectrum. Although it does not have optical image stabilization, which might be a problem when using Sony mirrorless camera bodies that do not have IBIS (In Body Image Stabilization), this Tamron superzoom is, all things considered, a huge success.
