I got this lens with a batch of stuff at an antiques market. There were some Pentax lenses in there and some not, so I really don't know. It doesn't fit on my Pentax KM camera. The box says "ACCESS Advanced Digital Technology 28-70 3.5-4.5 Manual Focus" and then on the side under that, "Filter Size 52mm Pentax K/Ricoh K". HOWEVER, the lens doesn't fit the styrofoam in the box. So I'm very confused as to what it is.
The lens reads "ACCESS * TEMPO" 1:3:5~4:5 f = 28~70mm" and then underneath says Macro. It has apertures 3.5, 5.6, 8, 11, 16, 22 and automatic. There is a sticker on it that says "PASSED JCII c/d JMDC".
Any ideas? I'm quite befuddled myself why the Pentax KM would come with so many lenses that don't work with it. I'd like to use these lenses but I don't know if they need a special mount or what. Help!
Thanks
