(SR5) Tamron will soon announce a new zoom lens (SR3) Is it a 28-75mm f/2.8 FE?

The Tamron teaser image is creating quiet a buzz on the web. What I know for sure is that this is a zoom lens. But the really surprising thing is that this might (I repeat might) be the very first E-mount Full Frame zoom lens from a third-party maker! Tamron was also the first thrid party lens maker launching an 18-200mm APS-C E-mount zoom (here on Amazon US, Amazon DE).

What about the Tamron lens specs?
We have no reliable confirmation yet but there is a chance this is the new Tamron 28-75mm f/2.8 FE lens. It would be amazing if true!

I am not a big fan of the 28mm at the wide end. But this lens goal is to be small and light as you can see from the size comparison I made here:

Size comparison between the “rumored” new Tamron 28-75mm F/2.8 Di III RXD FE lens and the Sony 24-70mm f/2.8 GM. It looks like it’s about 2cm shorter and a lot thinner. A perfect light travel zoom lens. – #sonyimages #sonyalphasclub #sonyalpha #sonyphotography #sonyphotogallery #sonyalpharumors #sonyalphagear #SonyPhotoGallery #SonyAlphasClub #SonyMirrorles #sonyalphaphotos #tamron
