The legacy Sigma Mini-Wide II 28mm 1:2.8, acclaimed on PentaxForums with ratings for Sharpness (8.6), Aberrations (7.4), Bokeh (7.7), Handling (8.7), and Value (9.2), is a follow-up to the original version, the Sigma Mini Wide 28mm 1:2.8, which was first released in 1978. While the earlier iteration has a metal aperture ring and a square pattern on the focus grip, the Mini-Wide II, has a plastic aperture ring and a focus ring with a diagonal pattern.
There is also a caveat that earlier versions of the lens tend to be infected with haze or wet microdroplets, with the glass pitted and damaged irreparably. The Mini-Wide II is the most recommended.
A good copy of the lens (mine is), however, is still worth the keep. The retrofocus lens is light and compact, weighs in at around 210 grams, comes with a 6-blade diaphragm, an aperture range from f/2.8 to f/22 at half-click stops, and a close focusing distance (CFD) of 0.22 meters, and takes 52mm filters. The Mini-Wide II was released in 1985, a redesign with one less glass element, and remained in production until 1995.
On a 2x crop sensor mirrorless, the lens is equivalent to 56mm on a full frame. It is a bit longer than a 50mm 'standard normal,' but long enough, with its 0.22 meters minimum focusing distance and silky smooth long focus throw, to draw in close-ups to a pin-sharp focus.

Image renders are excellent, with strong colors and acceptable contrast, especially in bright sunlight, and the lens is sharp even wide open. With the macro shots I do, flare, a common mention with the Mini-Wide legacy is not for me to worry about. The lens, with due consideration to its noted faults, is normally a low-end offer on auction listings.
