I was testing out my new 12-50 lens with Nauticam port today and have experienced a bit of a problem. I can switch from zoom to macro and in the zoom position I can zoom the lens in the wide direction but as soon as I release the zoom knob the lens pops back to the 43mm position. I cannot get it to hold at any setting wider than 43mm. I also cannot zoom from 43 to 50mm.
Before I disassemble the zoom gear and try to sort out what is wrong I thought I would see if any of you fine folks have any insights into this.
