Nice shots!
It's not a very known lens but some people swear by it. I even saw that just a while back someone left the first negative review of the SMC-A 70-210mm f4, which I thought everyone loved, saying "this lens is very good but I can't recommend it because the M 80-200 f4.5 is better". Of course I question basing a negative review on something like that, but it goes to show some people really like the lens, I guess like the M 75-150mm which got some really impressive numbers on a K-1, in a review by ephotozine (see here:
SMC Pentax-M 75-150mm f/4 Zoom Vintage Lens Review | ePHOTOzine ).
I also learned recently that there were two completely different versions of the M 80-200mm f/4.5:
M 80-200/4.5 (version 1) | The K-Mount Page M 80-200/4.5 (version 2) | The K-Mount Page
Version 1 has the metal ring on the front - beauty ring? - which version 2 doesn't have. Version 1 also has an insane optical formula for those days, especially for a 2.5x zoom - 15 elements in 12 groups! Version 2 has 12 elements in 9 groups like the M 75-150. The version 1 also has a floating element (well, two elements/1 group since they are cemented) like the A 70-210mm f4 - but that is interesting because this is not a "macro" or close-up lens. Version 2 might have it as well but I can't tell, there's no optical design image. It really seems like someone over-designed the first version for the film era and that might be why it performs so well on digital now...
Another lens that was perhaps a bit over-designed and was sold for a long time, well into the 80s, was the K 45-125mm f4. I've always had my eyes on one... the colors and rendering are beautiful and almost of "limited" quality.
