1. Introduction

Sony provides a comprehensive range of ultra high quality lenses for its Digital Cinema 4K

projector models to accommodate most common theatre auditorium throw ratios (see table

below).

The DCI’s 4K image resolution format of 4096 x 2160 pixels offers the potential to display

four times more detail than the 2K image resolution format of 2048 x 1080 pixels.

The optical quality of a 4K projection system also needs to be four times better than 2K

projection system optics.

The LKRL-Z200 Series 2D lenses are designed and manufactured to deliver exceptionally

high quality 4K image quality in conjunction with the SRX-R320 Series projection systems .

Lens Zoom range Focal Length mm

LKRL-Z211 x1.05 ~ x1.75 37.0 ~61.5

LKRL-Z214 x1.35 ~ x 2.41 47.8 ~ 84.6

LKRL-Z219 x1.85 ~ 4.0 63.1 ~ 137.7

Please note:

•The LKRL-Z200 Series lenses are designed for use with the SRX-R320 Series digital

cinema 4K projectors and are backward compatible with the (discontinued) SRX-

R220 in case of the need to replace a lens due to relocating the projector or

irreparable damage. They are not compatible with the SRX-R515P projection system

•The LKRL-Z200 Series lenses are also compatible with the SRX-T Series of Sony 4K

installation projectors.

•This Product Information bulletin refers specifically to use with the SRX-R320 Series

digital cinema projectors. Specifications and performance may vary when used with

other Sony 4K projectors

2. Projector and lens compatibility

There have been three generations of Sony Digital Cinema 4K projectors as of 2013.

The LKRL-Z200 Series lenses are compatible with the SRX-R320 Series projectors and

backward compatible with the SRX-R220 projectors which share the same 4 x bolt lens

mount and optical system.

The LKRL-Z200 Series lenses are not compatible with the SRX-R515P projector which

utilises a bayonet mount system.

4. Features

4.1 True 4K quality

Sony Digital Cinema 4K projectors are manufactured to meet the highest image resolution

specified by the DCI: 4K at 4096 x 2160 pixels.

The lenses are manufactured from ELD (Extra Low Dispersion) glass to create a superfine

pitch 4K image

4.2 Vertical and Horizontal shift capability

•Manual V and H shift adjustment

Under ideal conditions the lens should be installed with the centre of the lens lined up with

the centre of the screen to avoid “keystoning” of the image. In practice the projector will be

installed with a vertical offset to be higher than the back row of the auditorium seating. Also

under some circumstances it may not be possible to install it on the horizontal centre line.

Therefore, the lens has Vertical (V) and Horizontal (H) shift capability to compensate for

offsets in position between the lens centre and the screen centre.

The maximum range of lens shift varies depending on the lens model as shown below:

Lens Model V shift H shift

LKRL-Z211 +/-35% V +/-11% H

LKRL-Z214 +/- 50% V +/- 18% H

LKRL-Z219 +/- 50% V +/- 18% H

Figures for SRX-R320 Series

www.pro.sony.eu/dcinema 6

V shift is adjusted using a manual knob

located above the lens mount

mechanism.

The V shift adjustment is accessed via

a small door on the top of the projector.

There is an indicator (pointer arrow) on

the side of the lens mount mechanism

to indicate when the V shift is at its

mechanical centre.

•Electric V shift

The SRX-C also offers an electric V shift adjustment. Please refer to the SRX-R320

Installation manual for details.

Electric V shift would normally be used to correct for differences in the image centre position

when going from 1.85:1 ratio to 2.39:1 ratio. For example when aligning on a Scope shaped

screen:

•Display the 1.85:1 test pattern, adjust the lens zoom and focus to adjust the 1.85:1

test pattern to fill the screen height. Adjust manual V shift knob to line up the image

centre with the screen centre. Save the settings in the Function memory along with

masking etc.

•Switch to the 2.39:1 test pattern, adjust the zoom and focus to fill the height of the

screen. Adjust the Electric V shift to align the image centre with the screen centre of

necessary

4.3 H shift plate

The H shift plate is a new facility introduced on the LKRL-Z200 series lenses to simplify H

shift adjustment when swapping between 2D and 3D lenses where the projector.

The H shift plate is preset at the factory at the centre position (no H shift). If H shift is needed

during installation, the lens is adjusted for the required H shift and then the the H shift plate is

locked in position using the two adjustment screws. The plate ensures the H shift is preset at

the correct position which avoids having to readjust H shift every time the lens is swapped.

4.4 Lens Memory Function

The Lens Memory function enables Sony 4K digital cinema projectors to meet the single lens

requirement of the DCI specification for digital cinema so that the projector can re-frame an

image automatically when going between different aspect ratios such as 1.85:1 aspect ratio

during commercials and Scope 2.39:1 aspect ratio for the main feature movie.

The LKRL-Z200 series lenses are equipped with a

positioning sensor that feeds back to the projector

head the Zoom and Focus positions of the lens.

The lens has 3 connections marked as follows:

•Zoom – zoom motor drive connection

•Focus - focus motor drive connection

•Potentio – feedback from potentiometer

positioning sensors for zoom and focus

positions

The following diagram illustrates the difference between setting-up the framing for a

Widescreen (1.85:1) and Scope (2.39:1) images during installation. Two different zoom/focus

settings will be needed to correctly frame each aspect ratio image on the same screen. The

Zoom Memory function enables these settings to be saved and recalled to correctly frame

images during a show.

During the installation procedure Zoom and Focus are manually adjusted for each of the

image framing positions and the Zoom/Focus positions are memorised for each aspect ratio

setting by saving them in the Function Memory. During operation the lens can switch

between different aspect ratios by recalling the appropriate Function memory setting.

1.85:1 Image

For a 1.85:1 image on screen of wider

aspect ratio, you adjust the zoom

position to fill the height of the screen

For a wider aspect ratio image such

as Cinemascope, you adjust the

zoom to fill the width of the screen

5. Installation

1. Insert the lens into the projector lens

mount and fix with the 4 x (M8 x 25)

bolts supplied with the projector.

The screws can be tightened/loosened

with a cross head screwdriver but it is

highly recommended to use a 13mm

socket and ratchet with extender bar as

shown.

2. Connect the three cable harnesses;

Focus, Zoom and Potentio; to their

respective connectors on the

projector chassis.

3. Perform the lens alignment procedure as detailed in the SRX-R320 installation

manual
