I have a spare 14mm f2.8 Sigma-for-Nikon lens. I bought a spare for reason that the front element is very vulnerable to injury as it protrudes well outside of the lens body. However, I have thus far used the lens a lot less than I anticipated and have not damaged it so have not needed the spare.
It is a rectilinear lens which means that straight lines in the image remain straight, not curved in barrel distortion. Whilst barrel distortion is eliminated this characteristic introduces another artifact, that of diagonal stretching of the image into corners, most evident when the camera is moved.
If anyone is interested in this lens, let me know and I will list it on eBay.
