Hello gang - Hoping you could help me with a problem I'm having with my 110mm/f2.8 W RZ67 lens. I am using the lens on a RZ Pro II. I am just now getting acquainted with this body and lenses (bought it over a year ago). I have read the RZ Pro II manual as well as many of the troubleshooting threads here. I even have Bob Shell's Mamiya book and have read the appropriate sections in there as well. I have three lenses: > 65mm/f4 K/L L RB > 110mm/f2.8 W RZ > 180mm/f4.5 W-N RZ The 65mm RB and 180mm RZ lenses are functioning properly. I can see through the WLF, focus, and trigger the mirror/shutter successfully in M mode at various shutter speeds and apertures. The camera itself also seems to behave as expected with the warning lights (more on this later) when a condition presents itself to not allow the release of the mirror. My problem is with the 110mm lens. The shutter blades seem to be stuck in the closed position. At first, I thought this may have been a battery issue, but the 180mm lens functions as expected on the Pro II body. I then tried to use the 110mm lens in the emergency (fixed 1/400th shutter) mode, but no luck. The blades are still closed. From viewing through the back of the lens, I can activate the DOF preview just fine. I have cocked and released the lens manually multiple times but the shutter blades still won't open. Concerning the battery - It seems strong enough to allow the lights to function on the Pro II body but I cannot hear any beeping. Is it supposed to beep? I have some new batteries on order, but again, the shutter blades on the 110mm lens are still fully shut when installed or detached from the camera body so a battery issue may not be the culprit. I tried holding the lens alone with the shutter trigger release button/nib pushed down and giving it light taps/bumps but that didn't work either. Anything else I can try on the lens itself to release the blades? Thanks!
