Originally posted by pathdoc Which of the 55mm 1.2's is the basis for the Rikenon P? The Revuenon/Tomioka or the Porst/Cosina? I have always believed it to be the latter.
Is the euro cent disappearing, or is Italy going back to the Lira? (The one cent coin seems to be disappearing everywhere, mostly because its monetary value is less than that of the metal it's made with. Australia's one and two cent coins went an age ago, Canada followed suit by ditching the one very recently.)
Hahaha, no lira!
Personally i'm fine with euros in my pocket. You know, i live abroad...
The circulation of 1 and 2 cent coins was already stopped by most EU countries. Italy is just following the others.
Good under a practical point of view, though it should negatively affect inflation. Not that much i guess...
About the Cosina and Tomioka design, what i found from my own examples, from taking a close look to internet pictures is as such:
the Porst is a Cosina design (same as Cosinon-S)
the Revuenon is a Tomioka design (as the Ricoh, the Cosina, and few others)
This is only true considering f/1.2 lenses.
The Porst f/1.4 is actually a Tomioka design. This adds to the confusion.
My personal opinion is shared by more experienced collectors on mflenses.com

Originally posted by Digitalis I just prefer the aesthetic design of the K version. Having said that I own a copy of the A version the Pentax 50mm f/1.2, the A and K versions are literally the same lens.
I totally agree.
The build quality, and the "tactile experience" is at its best with the first generation of PK lenses. M lenses are a touch inferior, A lenses have a weaker build (plastic is introduced, weak diaphragm ring). Those who dare to dismantle AF lenses (i don't) say that F lenses have better internal build than the FA, despite their wobbly feel.
Usually i prefer A lenses over fully manual ones, cause they are a breeze to use, but i use the 1.2/50mm fully open, so i can shoot in AV and forget about the green button. I think it makes no sense to invest a lot of money in a Pentax-A, considering that the SMC Pentax has just minor limits.
