The image you see above gives us a look at what Ben Affleck's Batman might look like in Zack Snyder's Batman Vs. Superman. There is no indication on if this is real or fan made, but either way it's a great look, and that's definitely Affleck's chin.
The image popped up on the Superhero Hype forum and there's no source on where it came from, but it looks like a photo of an image. I doubt this is actual production art, but there's always a slight chance that it could be. The look is pretty much what I'm expecting to see in the film though, and I'd be happy with the design. It looks very similar to comic artist Jim Lee's Batman design that you can see below.
