Klaus Schroiff from Photozone (Click here) reviewed the new [shoplink 6821 ebay]Samyang 8mm f/3.5[/shoplink] fisheye for NEX, or better for the VG-10 (as this lens has been optimized for that camera). He tested the lens on the NEX-5. By the way he is an avid SonyAlhaRumors reader so feel free to make him the questions you need by commenting this post! In short: “The near-stereographic projection doesn’t look quite as extreme as in conventional fisheye lenses despite the similar field-of-view so its applications are in fact broader. It is also a pretty sharp lens if you stop down a little. Lateral CA can be a little high at times but this aberration is correctable during image post-processing.” He recommends that lens to all ultra-wide enthusiasts!
You can buy that lens on [shoplink 6821 ebay]eBay (Click here)[/shoplink]
