Konica Minolta 20mm f/2.8 Maxxum Lens

This is a 'superwide' focal length, no real bowing or pincushion effect, the corner and center sharpness exceeding the film resolution or chip pixel count. For a 35mm still frame it is "superwide" but for the smaller digital chips it is a good wide angle, sharper than almost any of the short focal length zooms.

If you need it, you need it, if you're a casual snapper, it may be more lens than you need.
