The Tamron 2.8/28-75 Di III RXD is the first third party E-Mount autofocus zoom lens. I am excited about this lens because it defines a milestone for the E-Mount system: until now, we only had a choice between Sony’s budget line, Samyang and the other (super-)expensive Sony/Zeiss options. The three classic third party manufacturers (Sigma, Tamron, Tokina) have been very tentative in their commitment to the E-mount system, and this lens is the first one that really changes this situation. The specs of the lens look spectacular on the paper, so let’s find out about its performance in the field.
In this review I will check the performance of my own copy that I used for several months now.
With the Sony A6500, Sony has entered the terrain of semi-professional crop cameras. The camera is significantly higher priced than other Sony APS-C cameras, and is directly competing with other smaller format flagship cameras like Fuji X-T2, Nikon D500, Olympus OMD-EM1 Mk2 or the Canon Eos 7D Mk2.
Furthermore, the Sony A6500 is now similarly (or even higher) priced than the Sony A7II. This leaves open the question for many people as to whether they should really spend that much on an APS-C camera, or if they should get a full frame body instead. The comparison is obvious, and legitimate, because the cameras share a few key specifications – like sensor resolution, mount, and sensor stabilization. Let’s check what sets these cameras apart from each other.
Since the introduction of the Contax Distagon 2.8/21 in the early 1990’s, the 21mm lenses from Zeiss have a long and glorious history of being some of the best wide angle lenses in the world. While the Loxia 2.0/35 and the Loxia 2.0/50 are refined ZM-Designs, the Zeiss Loxia 2.8/21 is the first Loxia lens that features a new optical design. Lets have a look if the Loxia 2.8/21 can keep the heritage alive. 31/05/17 Update by Bastian: I have been using this lens regularly for a year now and Jannik asked me if there is anything I would like to contribute to his review, so I added a few notes and sample images.
