Once in a while, I think to the webmaster that incidentally published a web pages of a product that has not yet been unveiled, officially I mean, by the manufacturer. Quite often, we know that these self-leaks are organized by the manufacturer itself. Canon, Nikon, Sony and Panasonic have already used that in the past while officially fighting hard against rumors and leaks making me sign constraining NDA contracts before they can even tell me the name of the product they are going to unveil.
Well, today, it looks like the mistake came from Sony Europe website webmaster that must have put a page online, accidentally. The interesting image is a new versatile lens, the 18-135mm f/3.5-5.6 SAM, that I would really love to see offered bundled with the new SLT-A57 DSLR announced last week. This lens gets an Alpha mount to be used with Sony Alpha and SLT HDSLRs offering a 27-202mm equivalent. The lens is not optically stabilized as the majority of Sony DSLR have CCD-shift image stabilization built-in. Its autoficus engine is not ultrasonic but SAM (Smooth Autofocus Motor) which still offers pretty fast and silent focusing to the SAM lenses. You will notice the lock button on the lens barrel.
The Japanese website digcame-info has spotted that image first.
