Attaching a Lens
 Chapter 2 Installation and Preparations
2-3 Attaching a Lens
Attach a lens that conforms to the PL lens mount.
Always use a lens whose projection from the flange (A in 
the figure) is less than 31.5 mm (1 
1
/
4
 inch). Use of any lens 
that protrudes more than 31.5 mm (1 
1
/
4
 inch) will damage 
the internal filter. 
For information on handling lenses, refer to the operation 
manual for the lens.
1
Rotate the lens fixing lever counterclockwise and 
remove the lens mount cap from the lens mount.
2
Align the lens’ alignment pin with the notch in the 
upper part of the lens mount and insert the lens into the 
mount.
3
While supporting the lens, rotate the lens fixing lever 
clockwise to secure the lens.
Changing the position of the lens fixing lever 
Remove the four screws from the face of the lens fixing 
lever indicated in the figure. Change the position of the 
fixing lever, reinsert the screws and securely tighten. 
Adjusting the flange focal length
The optical section uses materials not susceptible to 
thermal expansion, so flange back adjustment is generally 
not required. However, if you want to make an adjustment, 
remove the lens mount and replace the shim with one of the 
appropriate thickness. At shipment, a 0.05 mm 
(0.0020 inch) shim is installed. The following replacement 
shims are available. 
For information about replacing shims, consult your local 
Sony representative.
