Tamron is presenting the most compact*1 full-size, high-speed telephoto zoom lens, delivering leading-edge image quality with Tamron’s proprietary VC ( Vibration Compensation) and USD ( Ultrasonic Silent Drive).

Tamron Europe: Announcement: SP 70-200mm F/2.8 Di VC USD.

But not compatible with Pentax, just Canon, Nikon and Sony.

What will Ricoh Pentax do to convince Tamron to produce K-mount compatible lenses again?

According to recent speculation, it's possible that more rebadged Tamron lenses will be made by Pentax, i.e. for a future full-frame.

Pentax will need a Full Frame in order to sell more camera's for Tamron to notice it again. Consequently they will sell less lenses....

@Adam- i like how well you connect the dots

It's been an ongoing discussion in other threads that the 18-270 from Pentax may signal Ricoh's intent to renew and rebuild Pentax's relationship with the 3rd party lens makers. I sincerely hope so. At this time all I can say is that I am very glad that Samyang is still coming out with K-mount versions of its lenses.
