Originally posted by WorksAsIntended IF this is another Tamron rebrand, I will be very disappointed. It is a nice lens, but just too expensive with Pentax written on it and the missing vr is bad too. The Tamron not being available for Pentax is not a strong argument for me, especially as with the small market share Pentax does need to get new customers, not only users that already commited into their system.
I don't disagree that the Pentax version looks as if it will be considerably more expensive than the Tamron for a lens that is remarkably similar (though not identical). Pentax isn't the only brand to do this, of course... Sony, for years, re-branded Tamron lenses (with small Sony-specific tweaks) for A-mount and sold them at considerably higher prices than Tamron (also without image stabilisation, since the bodies - like Pentax - have it built in).

There is no argument, frankly. If you're sticking with Pentax, you'll need to get used to the idea of collaborations and re-brands (with, let's not forget, Pentax specific tweaks) where lenses are concerned, and accept the launch prices that Ricoh sets for Pentax lenses. That's just the way it's going to be. Alternatively, switch to a different brand and buy Tamron or other third party lenses. It's a fairly clear-cut choice...
