| Latest Review Posted | SMC Pentax 67 / SMC Pentax-6x7 165mm F4 Leaf Shutter
I debugged using the Leaf Shutter on the 645z with a Fotodiox adapter today. After some messing about I got consistent performance with the camera in manual mode, with a 1/15 second focal plane shutter. A key second step was using manual iris. With an auto iris synchronizing the two shutters was hit or miss - sometimes I'd get a full frame exposed, sometimes a partial. Flash synchronization appeared to work fine - I was using a Paul C Buff Cyber Commander transmitting to an Einstein. At that point I had flash sync and exposures 1 stop apart using 1/500, 1/250, 1/125, and 1/60 settings with the leaf shutter - I was able to balance ambient sunlight and the Einstein very nicely, with f/8 on the manual iris at ISO 400. |
