Re: Dave...

Too bad Kenko does not make the Pro 300 DGX series TCs in Pentax mount. That is considered the poor man's Canon II TCs. Way better than anything available for Pentax except the non-AF -L and -S Pentax series (but they lack digital friendly coatings). In my estimation the Kenko Pro 300 DGX 2x is better than the Pentax 1.7x AF TC. However the Pro 300 like the Canon II and III series will shut down AF electronically if the combo is more than F5.6. You can make it AF by taping one of the Canon contact points just like you can for the Canon II TC (but not the Canon III, because it can't be fooled by that). The Pro 300 TCs are 1.4x 5E-4G and 2x 7E-4G. They actually make a Pro 300 DG 3.0x also ( Kenko/Teleplus has always made a 3x all the way back to the M42 era).

Officially since the 2011 merger the combined company is now called HKT Imaging (HKT is Hoya- KenkoTokina, and it is KenkoTokina because that merger happened first and apparently Kenko was larger than Tokina). They also own Slik, Tasco-Japan, and Sightron.
