You want wide? I'll give you wide...hehe...to my knowledge, the Voigtlander 12mm is the widest non fisheye rectilinear lens made for any 35mm camera. It's ridiculously wide. I love it! :D It's available in Leica 39mm screwmount or M mount. Comes with an accessory viewfinder that clips in the hotshoe.

We’re fizzing with excitement to introduce our latest Kickstarter project: the Lomo’Instant Square. We’re talking about the world’s first analogue camera to produce square-format Instax pictures. It features a 95mm glass lens for super sharp photos, an advanced automatic mode that takes care of exposure, all of Lomography’s signature creative features — and a compact, foldable design. The Lomo’Instant Square has launched on Kickstarter. Come join the fun and back us on Kickstarter now to save up to 35% on the planned retail price, and scoop all sorts of extra treats. Be sure to snatch up the deals before they run out. Be there and be square!
