I have no idea about the 1.7/50mm. I own one. Can't say if it's Tomioka, Cosina, or Cosina/Tomioka
It's considered a good lens too.
All of them are good, from f/1.2 to f/2.
IIRC the Pentax 2/50mm is a 5-elements design, while all the Tomioka family is at least 6-elements (7-elements the faster ones).
I found that some Tomioka lenses are actually a tad better than their Pentax equivalent, despite the superior SMC coating of the latter.
Never tried the 28mm and 35mm. The 135mm I own has not been properly tested. First impression: (as reported by others) there is better, there is worse.
I am pleasantly surprised by the 35mm. As far as I understand you consider it much better than average.
It's not as common as the 28mm and 135mm, which explains the relative lack of info.
Btw, I like a lot the black and chrome livery of your Mamiya Sekor 55mm!
Looks almost the same as my 2/55mm.
My example has withstood very well the injuries of time. It works smoothly, as if it was new!

I envy your 1.9/80mm!
It should work fine as portrait lens on the K-1.
What's your impression?
I remember when you bought it. More or less at the same time you acquired the CZJ Sonnar 180mm.
I guess both could find their place along proper PK lenses. I mean, not just as a kind of sideline second duty...
