Introduction CineAlta 4K projection at (4096 x 2160) pixel resolution represents four times the resolution of standard 2K (2048 x 1080 pixels) and HD (1920 x 1080 pixels) projectors. Therefore, CineAlta 4K utilises higher quality optics to faithfully reproduce the higher resolution images. The current range of zoom-lens models were released to introduce the capability of a Lens Memory function to the CineAlta 4K projectors to fulfil specific requirement from the DCI specification. Lens Zoom Range LKRL-Z111C* 1.07 to 1.71 LKRL-Z114C* 1.35 to 1.98 LKRL-Z116C* 1.5 to 2.29 LKRL-Z117 1.73 to 2.41 LKRL-Z119 1.81 to 2.94 LKRL-Z122 2.23 to 3.92 * The “C” suffix indicates that these lenses can be used on SRX-200 series Cinema projectors only. The Z117,

Z119, Z122 can be used on the 200 series and the SRX-R110CE/R105CE series All of the models shown in the table are equipped with a potentiometer to act as a zoom-position sensor. This means that the lens’ zoom and focus can be adjusted to optimise the framing of images with different aspect ratios on to a screen and each of these zoom/focus set-ups can be stored in the projector memory. During a cinema presentation it is common to show material with different aspect ratios e.g. commercials are mostly 16:9, movie trailers can be in 2.39, 1.85 or 16:9 formats and the main feature will most frequently be in 2.39 aspect ratio. During the show playback, the lens will automatically* re-call the zoom/focus set-ups for the different aspect ratio material to display each part with optimum framing. This functionality is a requirement of the DCI for Digital Cinema applications. * Under the control of the LSM-100 Screen Management Software running the Show

Play List (SPL) on the CineAlta 4K projection system


The following diagram illustrates the zoom ranges for each lens in the line-up.

The zoom range of the LKRL-Z111C is from x1.07 to x1.71 meaning that the lens is suitable for cinema auditoriums where the screen width is similar in distance to the projection throw distance. This configuration is frequently used in modern multiplexes which employ steeply angled stadium style seating to bring the audience closer to the screen for a more immersive experience. Special Note: The ultra-wide angle performance results in a more restricted Vertical and Horizontal shift capability (compared with other lenses in the range) and extra consideration must be given to projector positioning (see section 4.3.2).


2.1 Lens Memory Function The CineAlta 4K projectors operate with electric driven zoom and focus which are adjusted from the SRX Controller GUI during installation. The projectors also offer a Lens Memory function which can only be used with the introduction of the new series of Cinema lenses. This facility is not available with the first generation of lenses – see section 8. Appendix – Obsolete lenses. The Zoom Memory function allows a number of zoom/focus positions to be stored in the projector’s memory and allows them to be recalled at the touch of a button. This is particularly useful if the projector is to show various inputs with different aspect ratios as part of a presentation. Each different aspect ratio content (commercials, trailers, movies) can be displayed on the screen during set-up and the zoom and focus positions adjusted to optimise the framing of the image on the screen. The zoom/focus settings for each input signal can be stored in the Zoom Memory for quick and easy recall during the actual show. The following diagram illustrates the difference between setting-up the framing for a 16:9 and Cinemascope (2.39:1) image during an 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 for recall later.

16:9 Image

For a 16:9 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

Cinemascope Image

Example: Two different aspect ratio images projected on the same screen*

* Most cinema screens will use constant picture height


The zoom/focus settings for the lens are set-up during installation using the SRX-Controller software. These are saved within the projector and are recalled by the SMS control software as part of the Show Play List function during screenings. 2.1.1 New lens connector In physical terms, the new LKRL-Z111C, Z114C, Z116C, Z117, Z119 and Z122 lenses differ from the previous generation of lenses because they have 3 connectors attached instead of two connectors. The three connectors are labelled FOCUS, ZOOM and the new POTENTIAL connector which provides lens-position feedback to the Lens Memory function. 2.2 DCI Compliance for digital cinema The Lens Memory function enables CineAlta 4K projectors to meet one of the requirements of the DCI specification for digital cinema. It requires that the projector should be able to re-frame an image automatically when going between different aspect ratios such as 16:9 aspect ratio during commercials and Cinemascope (2.39:1 aspect ratio) for the main movie. 2.3 Vertical and horizontal lens shift Ideally the projector should be positioned with the lens lined up with the centre of the screen in both the vertical and horizontal axis. This is often not possible when a film projector is already installed at the optimum horizontal-centre line of the screen and building limitations prevent the projection window from being aligned to the vertical-centre of the screen. The CineAlta 4K projectors are fitted with Vertical and Horizontal Lens Shift adjustments to help compensate for certain off-sets in the projector position. The Vertical and Horizontal Lens Shift functions are adjusted using the appropriate lens shift knobs on the lens mount structure.


2.3.1 V & H shift for LKRL-Z114C, Z116C, Z117, Z119, Z122 The LKRL-Z114C/Z116C/Z117/Z119/Z122 lenses offer a V-Shift capability of +/-50% of screen height as illustrated in the diagram below. The H-Shift range is 5% of screen width

2.3.2 V & H shift for LKRL-Z111C – restricted range! The wider the angle of view that a lens has, the smaller the range of Vertical and Horizontal lens shift adjustment can be applied for installations. The LKRL-Z111C is an ultra wide angle lens and as such has an extremely limited range for Vertical and Horizontal shift. • Vertical shift range = +/- 2% • Horizontal shift range = Zero, i.e. horizontal shift is omitted. Projector must be dead

centre if keystone errors are to be avoided If the projector with an LKRL-Z111C can not be installed in an ideal position – lined up with the centre of the screen - then the image will suffer from Keystone error and this must be discussed with the cinema owner before purchase to decide what level of keystone distortion they are willing to accept

4. Lens Calculator & Throw Distance Charts The correct lens can be calculated using either the on-line lens calculator tool or by using the Throw Distance charts and formulas included in this document. 4.1 CineAlta 4K Theatre Lens Searcher The Sony professional D-Cinema website, www.sonybiz.net/dcinema, provides an on-line lens calculator tool in the Reference Information section.

4.2 IMPORTANT: How to use Throw Distance Charts The Throw Distance charts are a collection of examples of screen widths and their corresponding maximum and minimum throw distances. They allow you to accurately estimate which is the right lens for an auditorium. For each lens model, the following pages contain example Throw Distance Charts for the 3 main picture formats; 2.39:1 Cinemascope, 1.85:1 Flat and 16:9.

(1) Find out the screen width and height as well as the thrown distance e.g. Screen Width=10m, Screen Height=5m and Throw Distance=15m

(2) Check the Throw Distance Charts for each lens to find which chart has a throw

distance of 15m (15,000mm) lying within the range of Maximum and Minimum Throw Distances for a screen of 10m wide (10,000mm). In the example below the Z111C Throw Distance range is from 10.6m to 17.1m for a screen 10m wide

(3) Check that the height of the screen is OK for the image height

In the example a 2.39:1 image of 10m width will be (10m/2.39)=4.18m high

(4) Check that the same lens will also be suitable for a 1.85:1 image for the same

Screen and Throw Distance dimensions using the next table in the list.

5. Appendix – Obsolete Lenses The first generation of lenses released with the original 4K projectors (SRX-R105CE and SRX-R110CE) were not suitable for Cinema use because they did not have a lens memory function to comply with the DCI Specification for cinema use. The LKRL-Z120 and LKRL-Z125 lenses have been discontinued. The LKRL-Z115 and LKRL-Z140 are still in production but can not be used for cinema applications where DCI compliance is required.
