Got it in a bag of other lenses a yeear ago. I have used the lens most on film, quality is acceptable. The lens are sold in other brands, cannot remember which. Made in Korea, Samyang? It has a nice close up distance, 20cm (8 inches). Here the lens, mounted on Micro 43 to PK adapter. It becomes a 56mm lens.
Sears 28mm 2.8 Olympus micro 4/3.
Standard picture of flower, f8.0
100% crop, fair quality.
My test chart
Center quality. Image upper left f 2.8, middle f 4, and so on.
We can se bad quality at f 2.8 and 4, rapid becoming better until f 22, then it is more blur.
Edge quality. As in the center, it becomes better from f 5.6.
Here, image on film, at f 11. The hood was to big, hence the vignetting.
Good contrast, sharp enough.
I like this lens, wide angle on film, do not have to be 100% spot on focus, close focus abilities, lightweight, fair quality, cheap, easy to get.
