One word: AMAZING considering the price and rendering performance. Caution: low light/underexposed focusing is not as good as on native Sony lenses.

(F2.8, 1/60, ISO 100, 64mm) For only $800, Tamron's 28-75mm f/2.8 Di III RXD is everything we could hope for in an E-mount lens that is within most hobbyists' budget. It takes incredible images, with the sharpness and color rendition that rivals its higher-end counterparts.

Don't underestimate the new Tamron 28-75mm F/2.8 E-Mount lens; It may come in a basic, unassuming package, so much so we thought we must have gotten a cheap third-party lens by mistake, but this is an incredible and versatile lens you'll start to appreciate as soon as you take your first photos with...

Unless you are pointing away from the sun or a strong light source, ghosting and flare are difficult to avoid with this glass, probably because it's using Tamron's older BBAR coating; These are easily reduced with a hood and filters, or removed in post, so we won't stress out about that...

Generally speaking, I'm not one to like zoom lenses; but when I considered what the Tamron 28-75mm f2.8 Di III RXD is then I didn't mind it all that much. The talk about autofocus issues are, in my opinion, highly over-exaggerated as I personally didn't see them with my unit.

Packing cutting-edge technology into a compact body, Tamron has created a high-speed zoom lens specifically designed for mirrorless cameras: the 28–75mm F/2.8 Di III RXD (Model A036).

As I write this review, the Tamron 28-75mm f/2.8 Di III RXD Lens is the #1 best-selling lens at B&H where, nearly a year after its announcement, it remains out of stock. Out of the many hundreds of lenses available, a Tamron lens compatible only with Sony alpha E-mount cameras is, at review time,...

The most affordable and sensible zoom currently available for E-mount. Hope to read a review here from LENSTIP soon. And: well done TAMRON.

Leightwight and small (compared to other Full-Frame f2,8 Zooms) Rather sharp in the center of images at open aperture Fast; precise and noiseless AF Available for a real good price

No Focus Switch available

While mirrorless systems have been around for quite some time, the uptake by the "big 3" third-party lens manufacturers was neither fast nor overly broad. Of course, in the end, it is a number game.

Take a step up the quality ladder from your A7-series kit zoom lens with the Tamron 28-75mm f/2.8 Di III RXD...

• Faster aperture than the Sony 28-70mm; • Constant aperture through the zoom range; • Great image quality and all-round performance

• No optical image stabilization; • Lacks the wider viewing angle of a 24-70mm zoom
