Tamron 28-200 F/2.8-5.6 Di III - Review

As a devoted Sony mirrorless camera user, I have been eagerly awaiting a lens like the Tamron 28-200 F/2.8-5.6 Di III RXD. As soon as it was released, I knew I had to get my hands on it and test it out for myself. After several weeks of using it in various shooting situations, I am beyond impressed with its performance.

First and foremost, the Tamron 28-200 F/2.8-5.6 Di III RXD is incredibly lightweight and compact, making it the perfect travel companion. At just 20.3 oz. and 4.6" in size, it fits easily into my camera bag without taking up too much space or weighing me down.

But don't let its small size fool you - this lens truly packs a punch when it comes to its versatility and image quality. As the world's first F2.8 all-in-one zoom lens for full-frame mirrorless cameras, it offers a wide range of focal lengths without sacrificing image quality. Whether I'm shooting landscapes, portraits, or street photography, this lens always delivers sharp and detailed images.

What really sets the Tamron 28-200 F/2.8-5.6 Di III RXD apart is its superior close-up shooting performance. With a minimum focusing distance of 7.5" at the wide end and 31.5" at the telephoto end, I can get up close and personal with my subjects without having to switch to a dedicated macro lens. And with a maximum magnification ratio of 1:3.1 at the wide end and 1:3.8 at the telephoto end, I can capture incredible detail and texture in my close-up shots.

But what about the autofocus performance? As someone who primarily shoots with autofocus, I was pleased to discover that the Tamron 28-200 F/2.8-5.6 Di III RXD's RXD stepping motor unit is exceptionally quiet and quick to lock onto my subjects. I have used it in a variety of lighting conditions and have never had any trouble with focus accuracy or speed.

One thing to note is that this lens is designed specifically for Sony mirrorless full frame/APS-C E-mount cameras. While it works perfectly on my Sony Alpha A7III, it may not be compatible with other camera brands/models.

In terms of build quality, the Tamron 28-200 F/2.8-5.6 Di III RXD feels sturdy and well-constructed. It has a moisture-resistant construction, which has come in handy during a few rainy shoots. The zoom ring and focus ring both feel smooth and easy to control, and the lens mount feels secure when attached to my camera body.

Overall, I would highly recommend the Tamron 28-200 F/2.8-5.6 Di III RXD for anyone looking for a versatile all-in-one zoom lens for their Sony mirrorless camera. Its compact size, superior close-up shooting performance, and fast and accurate autofocus make it a must-have for travel and everyday shooting. I am extremely happy with my purchase and look forward to using it for many more shoots in the future.
