Price and Availability Announced for Tamron's 28-75mm Sony E-Mount Zoom

Tamron's first full-frame E-mount starts shipping next month.

In February, Tamron announced the development of two lenses, a 70-210mm F/4 Di VC USD compact telephoto for APS-C sensors and the 28-75mm F/2.8 Di III RXD (Model A036). We now know the availability and price of the latter. It ships May 24th, 2018 for the cost of $799. 

The optical design features 15 elements in 12 groups including a XLD (eXtra Low Dispersion), LD (Low Dispersio), GM (Glass Molded Aspherical), and two hybrid aspherical lens elements. At 28mm, it touts a 7.5 inch minimum object distance and a total working distance of 2.24 inches. The MOD at 75mm is 15.3 inches. As one might expect, it also has a moisture resistant construction, flourine coating to wick away dirt and fingerprints, and Tamron's anti-reflection coating dubbed BBAR (Broad-Band Anti-Reflection). 

Tamron 28-75mm

Compatible with Sony E-mount full-frame mirrorless cameras, the nine-blade circular diaphragm features a fast F/2.8 aperture and a new AF driving system, the Rapid eXtra silent stepping drive (RXD for short). Tamron says the new AF system "strikes a balance between speed and silent operation, making it perfect for video and still image capture." Additionally, the company mentions it will match camera specific features, including in-camera lens correction and Sony's Fast Hybrid AF, Eye AF, and Direct Manual Focus (DMF) system. 

It's worth noting the amount of E-mount lenses being launched. Earlier this year, Sigma announced that its Art prime lenses will be available via E-mount ranging from 14-135mm, including a new 70mm Macro and 105mm F1.4. Sigma hasn't said it will be offering E-mount zoom lenses, but if the primes do well, we're sure zooms will be available.

At the moment, Sigma offers a 24-70mm F2.8 for $1,299 which you will need to add the MC-11 converter to make it E-mount compatible. It costs an additional $249. The Tamron 28-75mm zoom comes in at $799, or about $800 cheaper. The only question we have left is what type of quality is being sacrificed at that cost.

A bit of a useless focal range no?

The ubiquitous Canon 24-105 with a metabones gives me 18-80 f/2.8 on e-mount, so this Tamron is just kind of like a less useful version of that setup.

I hope they keep making e-mount lenses though, but perhaps a little more market research would benefit them. Lots of opportunity to capture FS7/FS5/A7 shooters attention!

It's basically a 24-70mm – the most common full-frame mid-range zoom lens across all brands. Sure, those 4mm on the wide end will be missed, but calling it a useless focal range is... a niche opinion.

Well that’s true, but I guess my point is why not just buy any of the 24-70 or 24-105 options already on the market?

There is a big difference between 24mm and 28mm, so announcing a lens with less features and less capability than what’s already on the market, for similar price points, doesn’t make much sense to me.

You may be missing the fact that the 28-75 is an FE lens.

From the article:
At the moment, Sigma offers a 24-70mm F2.8 for $1,299 which you will need to add the MC-11 converter to make it E-mount compatible. It costs an additional $249. The Tamron 28-75mm zoom comes in at $799, or about $800 cheaper.

If you need E mount for some reason, why not just buy the Sony 24-70 for $800 and call it a day?

Canon 24-105 with metabones speedbooater (18-80 f/2.8 equivalent) is ubiquitous for Sony cameras, so again I don’t see the point in releasing a lens with substantially less capability than what’s already on the market.

28 isn’t wide enough, 75 isn’t tight enough = DOA.
