Tamron SP 17mm f/3.5 is an ultra-wide angle, high speed lens with an almost non-existent lateral color.

Performance is slightly to moderately soft towards the corners wide open at F/3.5, improves at F/4, is very good by F/5.6, and is excellent between F/8 to F/16. It has a built-in filters for black and white photography. Distortion is effectively controlled (about 1%) except that the this distortion is non-linear and varies from a very slight pincushion to a very slight barrel from about 40% off-axis to about 70% off-axis. Yet distortion along all four edges of the film plane is almost non-existent.
