What are the real gems in the A, M, K and Takumar series
I have been reading the posts in the different "club" threads (last weekend all 1000 in the Takumar club!). From reading all those posts I concluded that there must be a number of real gems in the different Pentax series of lenses, eg. the Takumar 55mm F1.8 seems to be very highly rated by everybody who has ever used the lens (and the outstanding pictures in the Takumar club prove it!).
Is there some sort of general consensus on what the real gems are in the Pentax A, M, K or Takumar series? A gem should not only be a very good lens but also way beyond expectations. An expensive A* lens should be high quality but it should also perform beyond its price class to be considered a "gem". Again, a good example would be the 55mm F1.8 kit lens of the past (K series or Takumar).
* These lenses are rare and priced as if they are the best lenses ever made. The others are attainable price-wise. The K28 could be the sharpest Pentax 28; the 35 is renowned for color rendition and bokeh; the 50 is a Pentax 50 - 'nuff said; the 135 is just a great, fast medium telephoto.
A 50 f1,4
M 135 f3,5 (from what I've seen)
to some extend, Takumar bayonet 135 f2,8 (if you get a good copy, for the price it used to cost and the wide aperture)
I'm not sure if it qualifies, given your definition of "gem", but the Vivitar Series 1 70-210 version 1 and 3 (I own v1) are just wonderful, even legendary. I'm always blown away by the resolution, contrast, and colours of mine.
I have one of those which I never use... I keep contemplating selling it but it takes such great photos, I can't seem to part with it. It would be great for candid street photography (if you're into that sort of thing ).
I would like to add the DA 14mm f2.8... For the price against what canon or nikon have.. It's the one of the best Wide's for low light around. Close focus so great for indoors.
