Aren't the Tamron SPs a little big for the "Limited" ethos?
See how big the new D-FA* 50mm F/1.4 is compared top the current FA 50mm F/1.4. If Ricoh is going to build glass that can take advantage of future 70-100MP sensors they are going to be bigger. The Tamron SP line of primes are very much in the mold of the Limited glass. Pentax users would be happy to have them as an option.
Tamron's core business is building OEM lenses for Nikon and Canon..... and the Pentax D FA 24-70mm F/2.8 & D-FA 15-30mm F/2.8. Both great lenses. Tamron also makes the Zeiss Batis line of lenses for the Sony E-mount system. The 135mm F/2.8 APO Batis is a really good lens.
