I am accumulating primes with Tamron adaptall-2 hoping to get 17mm, 24mm, and 28mm for wide angle needs with my film bodies. I recently got 51B on the 17mm from another great forum member. It is quite interesting to see a prime with built-in internal filters. I plan to use the 17mm with my film gear and the view is quite wide in the film body. Some LBA product shots to share:


The Y2 is a yellow filter, I see darkening color in 81B and some other change in 80B. When I asked around for the use of the filter, I learned that 80B and 81B are used for warming effect.

17mm is not wide when used on aps-c camera with my K20D but it is very wide when I put it on my Pentax SuperProgram and Pentax MX and the view is quite spectacular. I noted some distortion in the test shots and I think more use will help. I am hoping for a small sets of mixed primes and zooms to be used with my film gear stepping out of my comfort zone into film where one has to think in composing a picture.

• Tamron SP 17mm f/3.5 (51B) -- this prime
• Tamron 24mm f/2.5 (01B)
  
• Tamron 28mm f/2.5 (02B)
  
• Tamron SP 35-80mm f/2.8-3.8 (01A)
  

All the adaptall-2 have aperture rings and with the adaptall-2 p/k-a adapters, they will work fine in SuperProgram as well as MX for street scenes, candids, close-up and portraits. My nostalgic film experience is my high point with the adaptall-2 lens series. And I can adapt to another system using the same sets of lens for Ricoh xr-p or Nikon F series of 35mm camera. Oh my gosh, I wish I can use them with my 645N camera and I can surely benefit from the adaptall-2 system. With usage in both Pentax film bodies, my Pentax digital bodies with K-x and K20D, and my Praktica MTL5 in M42 mount, I can't complain how adaptable the adaptall-2 system is. Bravos to Tamron who came out with such a great system for ease of adaptation to one's system of their choosing.
