I have just acquired a 135mm LS from KEH. Tested in the studio and as soon as I attached to the 645z LS appeared on the LCD display. Initially tested with a sync cord to my Profoto and really pleased with the results. But realized why I now hate sync cords. Put a Pocket Wizard Plus III in the hot shoe and connected the cord to the sync socket on the lens and voila cordless operation at all shutter speeds on the lens. Also works great in non-LS mode (LS disappears in the LCD finder) and in manual mode can use all the camera shutter speeds.

The image quality of the lens is really good, sharp, good rendering of out of focus elements and no CA. Just like a poster above this lens will take over from my A150 and 120mm Macro Having to manually cock the shutter is no big deal and quickly becomes part of the workflow.

LS lenses on the K-1

Has anyone figured out a way to use the Pentax 645 75LS or 135LS outside their native Pentax 645 environment? On the K-1, for example. Or how to use Pentax 67 LS lenses outside their native 67 environment? On the 645D/Z, for example?
