Hi, I tried zephyr camera plate on old SK2 i have. It does fit and can be locked using the thumb screw. You need to remove safety screw on one end of the plate so it can slide in (and dont forget to put the screw back in place!) . Also - you dont have control of the fore/aft knob as zephyr plate was not built for a rack/pinion system like the SK2 has - it may be a challenge to balance this arrangement ... i would ask Tiffen for advice...
