Some Z-mount lenses have restrictions that don't allow them to be used in pure Mechanical shutter mode (the lens will make Shutter type default to Auto):
- 24-120mm f/4 S
- 28-400mm f/4-8 VR
- 70-180mm f/2.8
- 85mm f/1.2 S
- 100-400mm f/4.5-5.6 VR S
- 105mm f/2.8 VR S
- 135mm f/1.8 S Plena
- 180-600mm f/5.6-6.3 VR
- 400mm f/2.8 TC VR S
- 400mm f/4.5 VR S
- 600mm f/4 TC VR S
- 600mm f/6.3 PF VR S
- 800mm f/6.3 PF VR S
And DX lenses:
- 12-28mm f/3.5-5.6 PZ VR DX
- 16-50mm f/3.5-6.3 VR DX
- 18-140mm f/3.5-6.3 VR DX
- 50-250mm f/4.5-6.3 VR DX
Note: this does not apply to Z8 and Z9 cameras, as they do not have mechanical shutters.
