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

inch). Use of any lens

that protrudes more than 31.5 mm (1

inch) will damage

the internal filter.

For information on handling lenses, refer to the operation

manual for the lens.

Rotate the lens fixing lever counterclockwise and

remove the lens mount cap from the lens mount.

Align the lens’ alignment pin with the notch in the

upper part of the lens mount and insert the lens into the

mount.

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.
