OK...a thread for lenses that aren't as fast as * lenses nor as compact or well-built as Limiteds

; in other words, lenses that we really like, but didn't pay a premium price for that are Pentax-branded. Knowing that legacy fast 50s (f/1.2 versions excepted) were generally sold at a loss, I nominate the two examples below. Both feature excellent, all-metal build, fast maximum aperture, and world-class optical performance at the time they were made.
Pentax-K 55mm f/1.8
Pentax-M 50/1.7
If made today, both would be priced and esteemed on the same order as the late and much lamented Cosina-made Zeiss and Voigtlander 50s.
