A new 15mm wide angle lens has come on the market. Available for full frame cameras from Nikon, Canon and Pentax.  I am wondering how it performs against the Samyang 14mm F2,8.  The sample images on the Irix website look promising.

The good thing: Irix offers 2 versions, 1 light weight and 1 heavy duty with weather sealing. Also you can use drop-in gel filters.

Here is their Youtube video.
