Originally posted by Wasp Very nice find, that one. It must be fairly rare. I have often wondered why Pentax made it. Not very many other manufacturers offered a 120mm for 35mm cameras, AFAIK.
It is a shame that people butcher perfectly good lenses just because they are cheap. Perhaps those slow blades are a result of the "conversion." Keep us posted on the outcome of the repair.
I think that I wrote too quick in that end of the aperture lever looks altered and reduced ... it's really not that much, but it has been filed down or well cut. Nice and shiny metal to be seen on that tip ... and ugly.
I just compared this 120 to my M 100/2.8 and there's really not that much of a difference ... so, maybe it was only slightly "Canon-ized" to pass safely on an APS-C body. Or maybe I was just flat out wrong here ...
I tried the 120 on the K-1 and if the shutter is set below 1/2 second, there's enough time for the aperture to engage ... I mean that it's REALLY SLOOOOW. The 120 seems to stop down correctly if enough time is given ... also tried on a MX with the same end results. So, maybe I jumped to gun on this one upon its first inspection, but that's all the better for me ... Cheers.
