I just recieved my 3rd of the same lens. Buying a replacement was always a cheaper bet than a full CLA at a good shop after having the first messed up by a hack. My latest is an earlier verion, early serial number but still 7 element, holy moly is the focus ring smooth! The later version I have just isn't anywhere near as nice. Apparently they moved from brass to aluminium over the years? Simply a wonderful lens. I've tried the SMC K mount version some years back but didn't bond with it.
I really like the 35mm f2 Super Tak's rendering, I got it as a freebie, but I've never bonded with 35mm as a focal length so it sits there lonely most of the time,
Another lens I really liked was the FD 24mm f2, I really wish I hadn't sold it back then, it's now selling for silly money.
Playing with the idea of the Pentax K 135mm f2 to try as a longer solution though not that sure.
