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

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

8. Replacement of LKRL-Z100 Series lens
The LKRL-Z100 Series lenses were shipped prior to 2011. The introduction of the LKRL-
Z200 Series lenses (with two new lenses benefiting from a wider range of zoom ratio)
reduced the number of models from 6 lenses down to 3 lenses.
It may become necessary to replace the LKRL-Z100 lens on an early SRX-R220 projector,
for example: if relocating an SRX-R220 to a different auditorium with a different throw ratio or
in the unlikely event of an irreparable failure/damage to an LKRL-Z100 Series lens.
The diagram below highlights the original LKRL-Z100 Series lenses and their LKRL-Z200
Series equivalents.
