Hello all,

I have a brand new 24-70 - AF-S,Nikkor, N-VR @ 2.8
Using a Nikon Mount for the SCARLET.

But when the lens is mounted the aperture is fixed at f2.8 - and will not change.
I've tried automatic lens calibration with no success, and attempted to apply a calibration from a different 24-70, also no success.

Firmware is 5.2.29.

Does anyone have any knowledge of this issue?

Many thanks!
