Originally posted by Ira That's interesting, because like I said above, Mamiya (M42) had a 1.2 at the latest in 1973.
But this is going by memory, and if you remember that era at ALL, things got a little foggy for those of us in high school.
Yep could be I'm not sure about other manufactures lenses back then, I got into Pentax in late 1975 when I bough my first SLR the KX and a K55/1.8. There was no way I could have afforded the K50/1.2 as a teenager making around $2.00 an hour! So I did not pay much attention to the other faster lenses.
I have a Pentax “K Series” brochure from 1976 that I checked and it lists the improvements in the new K series lenses:
- The bayonet-mount
- SMC seven layer coatings
- “
The world’s first 50mm f/1.2 lens for an SLR camera.”
- “
The world’s fastest 50mm SLR lens – the remarkable new 50mm f/1.2 SMC Pentax lens.”
Of course take these firsts with a grain of salt, I have no doubt the K50/1.2 was Asahi Pentax’s first f/1.2, but the world's?? (Note they don't mention 55mm)
