Finally…Tamron announced that the popular SP 17-50mm F2.8 Lens will be available in Pentax K mount from 7th March 2008!
SP AF17-50mm F/2.8 XR Di II （Model A16）
This is one of the BEST Selling lens at ShaShinKi.com, best budget lens with F2.8 aperture and no compromise in image quality! It sure is going to be of HIGH DEMAND initially…definitely worldwide shortage for stock in the first few months.
Even as of now, Canon and Nikon mounts of this lens are constantly sold out in many places.
