While Sony has yet to announce the Xperia Z5 Compact, it looks like a promo shot has all but officially confirmed the existence of the handset.

A Dutch website, TechTastic, says it managed to get the promotional shot, which shows the back of the handset.

While it's difficult to verify the image, it does seem to point at a design that is in line with the Xperia Z-branded phones from Sony so far.

But bigger than the promo shot, the Dutch website has also seemingly gotten its hands on the Xperia Z5 Compact handset itself.

While it hasn't posted a photo of the handset, the site did include the leaked image from ViziLeaks that popped up about a month ago, saying the design of the Xperia Z5 Compact is in line with these images.

It adds that the buttons along the side of the phone is placed further down (which can be seen in the promo shot, too), with the rounded power button of previous Xperia Z handsets replaced by a fingerprint scanner.

Of course, none of this can be truly confirmed until Sony announces the Xperia Z5 Compact, which is expected to happen next month at IFA 2015, so until then, make sure to have a grain or two of salt.
