Originally posted by Jonathan Mac The M series sits in the middle of what makes vintage Pentax lenses great: optically better than the Takumars, mechanically better than anything that came after, lighter than the K series but still nice and solid. Lenses need to be assessed on their individual merits, but overall I think the M series is the best that Pentax produced.
That's well said. Lens design is always a compromice and in M's features are well balanced.
I have some cheap zooms and few M42 primes to play for next year to test how I feel about those. But I think my travel bag will be mostly M's also in future, so I'll be dropping shots
