Laowa 15mm f/2 FE Zero-D Lens for Sony E Mount. Full frame lens, but can also fit APSC cameras.  

Excellent, barely used condition. Comes with lens hood and both end caps.  

 

This is a MANUAL FOCUS lens. Reason for selling--I have too many wide angle lenses, and use this one the least.  It is great for astrophotography, which is one of the main reasons I bought it.

Also great for wide angle close up (macro like) photography as it gets to 1:4 magnification ratio. Check out that great tulip shot I took--the lens makes nice sunstars as well. 

Some good reviews with excellent photos showing what it is capable of:
