DISPOSAL OF ELECTRICAL AND ELECTRONIC EQUIPMENT
(Applies within the EU and for other European countries with active waste separation policies)
This device contains electric and/or electronic components which must not be disposed of in general household waste. Instead, it should be disposed of at a recycling collection point provided by your local authority. This service is free of charge. Any standard or rechargeable batteries used in this device must be removed and disposed of separately in accordance with local regulations.
Please contact your local authorities, waste disposal collection point or the retailer, from whom you purchased the device for more information on correct waste disposal.

SAFETY REMARK

• A camera lens can have the effect of a magnifying glass when exposed to direct frontal sunlight.
  The camera must therefore be protected against extended exposure to direct sunlight. Using the lens cap and keeping the camera in the shade (ideally in its camera case) will help prevent damage to the interior of the camera.

GENERAL INFORMATION

• Make a note of the serial numbers of your camera (engraved in the base of the camera housing) and lenses, as this information will be extremely important in case of loss.
• Make sure to always have a lens or the camera bayonet cover attached to prevent dust or other foreign bodies penetrating the camera.
• That is why you should always replace lenses quickly and in a dust-free environment.
• Never store the camera bayonet cover or the rear lens cover in a pants pocket, as they will attract lint and dust, which could then be accidentally introduced into the camera.
• Leica releases firmware updates for lenses at irregular intervals. You can download any new firmware version from our homepage and transfer it to your lens.

SPECIAL FEATURES
Please visit the Leica Camera AG homepage for more information about the visual and technical details: http://us.leica-camera.com
DESIGN OF THE LEICA SL LENSES
All Leica SL lenses basically look the same on the outside: On the front mount there is an external bayonet fitting for the lens hood and an internal thread for filters, as well as a focus ring and an alignment button for lens changes.
All data exchange between the camera and lens is effected via a contact strip in the bayonet, including the control commands for autofocus and aperture.

FOCUSING
In autofocus mode, the camera sets the sharpness automatically, while the user turns the focus ring 3 manually in manual mode. The speed at which you turn the ring determines how quickly the setting changes. You can therefore make fine adjustments or quickly move from a close-up to a long range setting. Please refer to the relevant sections in the camera manual for more details.
DEPTH OF FIELD
No depth of field scale is provided, because Leica SL lenses don’t come with an aperture settings ring. Instead, the top display of the camera shows the near and far focal length limits of the depth of field alongside the set distance.
LENS HOOD
The APO-Summicron-SL 35 f/2 ASPH. comes with a lens hood optimally adapted to the beam paths. As the bayonet fitting is perfectly symmetrical, the lens hood can be attached in reverse for space-saving storage. In both cases, it is attached (with the lens cap removed) with one of the alignment points on the lens hood aligning with the alignment point on the front mount of the lens . It is then turned by approx. 30° in clockwise direction until it audibly clicks into place. The lens hood should remain attached as long as the camera is carried ready for use or is in use. It effectively eliminates contrast- reducing stray light and protects the front lens against damage and soiling (e.g. accidental fingerprint marks).
FILTERS
The APO-Summicron-SL 35 f/2 ASPH. is compatible with screw-in filters of type E67. Matching filters are available from Leica.
REPLACEMENT PARTS/ACCESSORIES

FIRMWARE UPDATES
Leica is continuously working on the further improvement and optimization of your camera. Since many camera functions are entirely controlled by software, some of these improvements and additions to the functional scope can be installed in retrospect.
Leica offers firmware updates at irregular intervals, which you can download from our website.
Leica will notify you of any new updates, once you have registered your camera. Users of Leica FOTOS will also be automatically notified about firmware updates for their Leica cameras.
There are two options for installing firmware updates.
– conveniently via the Leica FOTOS app
– directly via the camera menu
Finding the currently installed firmware version
Select Camera Information in the main menu
• The current firmware versions are displayed.More information about registering, firmware updates and how to download them to your camera, as well as any amendments and additions to this manual can be found in the customer area of our website at: https://club.leica-camera.com

EXECUTING A FIRMWARE UPDATE

Any interruption of a running firmware update may cause serious and irreparable damage to your equipment!
You will therefore have to take particular note of the following, when carrying out a firmware update:

• Do not switch off the camera!
• Do not remove the memory card!
• Do not remove the rechargeable battery!
• Do not detach the lens!

Notes

• A warning message will appear if the battery is insufficiently charged. Recharge the battery and then repeat the process described above.
• You will find additional device and country-specific registration marks and numbers in the Camera Information submenu.

PREPARATION

• Fully charge and insert the rechargeable battery

• The second SD memory card (where applicable) must be re- moved from the camera

• Any stored firmware files on the memory card must be removed

  • We recommend saving any images on the memory card and reformatting it before the update.
    (Caution: Loss of data! All data stored on the memory card will be lost during formatting.)

• Download the latest firmware version

• Save the download to the memory card

  • The firmware file must be stored in the main directory of the memory card (not in a sub-directory).

• Insert the memory card into the camera

• Switch the camera on

UPDATING THE CAMERA FIRMWARE

• Preparation
• Select Camera Information in the main menu
• Select Camera Firmware Version

UPDATING THE LENS FIRMWARE

Where available, firmware updates can be performed for Leica SL lenses and for all other lens types by L-Mount Alliance.
Firmware updates for Leica SL lenses are generally uploaded alongside the latest version of the camera firmware and will not have to be implemented manually. Provided an SL lens is attached during the camera update, it will automatically receive the latest firmware version. Where that is not the case, a relevant prompt will appear when a lens is attached to a camera with updated firmware for the first time.
The instructions provided for camera firmware updates apply.

• Preparation
• Select Camera Information in the main menu
• Select Lens Firmware Version
• Select Start Update
  • A prompt with information about the camera is displayed.
• Check the version information
• Select Yes
  • The update will start automatically.
  • The lower status LED will flash during this process.
  • Once the process has completed successfully, a relevant on- screen message and prompt to restart the device will appear on screen.
• Switch the camera off and on again

FLASH MODES

Select one of the three available operating modes.
– Automatic
– Manual
– Long-term exposure
AUTOMATIC FLASH ACTIVATION
That is the default flash mode. The flash unit will fire automatically if poor lighting conditions would mean slower shutter speeds, which could result in blurred images.
MANUAL FLASH ACTIVATION
This mode is suitable for backlit pictures in which the main subject does not fill the entire frame and is in shadow, or in situations where a fill-in flash will moderate sharp contrasts (e.g. in direct sunlight). The flash will fire each time a picture is taken, regardless of prevailing lighting conditions. The flash intensity depends on the metered ambient brightness: in poor light it is the same output as in automatic mode, with output decreasing with increasing brightness. The flash will then work as a fill-in light, e.g. to light up
dark shadows in the foreground or backlit objects, and to create more balanced overall lighting.
AUTOMATIC FLASH ACTIVATION AT SLOWER SHUTTER SPEEDS (LONG-TERM SYNCHRONIZATION)
This mode ensures appropriately exposed, brighter dark backgrounds and bright foreground.
The shutter speed is not extended beyond 1⁄ 30 s in the other flash modes to minimize the risk of blurring. This may mean, however, that pictures with flash exposure can end up with objects in the background not illuminated by the flash and therefore being underexposed. In this mode, slower shutter speeds (up to 30 s) are permitted to avoid this effect.

• Select Flash Settings in the main menu
• Select Flash Mode
• Select the desired setting
  • The currently active mode is displayed on screen.

PLAY MENU

DELETING IMAGES
DELETING UNRATED IMAGES

• Press the MENU button
• Select Delete Unrated in the play menu
• The prompt Do you really want to delete all not rated files? appears.
• Select Yes
• The LED will flash during the deletion process. The process may take a few seconds. The next marked image appears once deletion is complete. The message No valid picture to play appears if no other images are saved on the card.

Note

• The message No valid picture to play. appears after success- ul deletion. The same image is displayed again if deletion was unsuccessful. When deleting several or unrated images, a notification screen may appear for the time needed to process the data.

ISO SENSITIVITY (IM VIDEO MODE)

AUTOMATIC SETTING

The camera automatically adjusts the sensitivity to ambient brightness and/or to the configured shutter-speed/aperture combination.
In conjunction with aperture-priority mode, this function extends the range for automatic exposure control.
The automatic setting of ISO sensitivity occurs in increments of 1⁄ 2 EV or 1⁄ 3 EV, depending on the selected EV Increment setting.

• Select ISO in the main menu
• Select Auto ISO

Note

• This function is not available in Cine mode.

LIMITING SETTING RANGES
A max. ISO value can be set, which will then limit the automatic setting range (Max. ISO value). A max. exposure time can also optionally be configured.
There are automatic settings and fixed max. shutter speeds 1/30 s and 1/2000 s available for that purpose.

LIMITING ISO VALUES
All values from ISO 100 are available.
Factory setting: 6400

• Select Auto ISO Settings in the main menu
• Select Maximum ISO
• Select the desired value

LIMITING SHUTTER SPEED RANGES
Factory setting: Auto

• Select Auto ISO Settings in the main menu
• Select Shutter Speed Limit
• Select the desired value (Auto, 1/2000, 1/1000, 1/500 , 1/250 , 1/125 , 1/60 , 1/30)

ISO VALUE LOCK
Factory setting: Off

• Select ISO in the main menu
• Select Auto ISO – Lock

Notes

• During video capture, the ISO value can be modified via the FN button or the thumbwheel.
• You can toggle between Auto ISO and Auto ISO – Lock, or switch to another fixed ISO value. However, you cannot switch from a fixed ISO value to Auto ISO – Lock during video capture. In that case, the Auto ISO – Lock will be grayed out.

DYNAMIC ISO SETTING
The thumbwheel and front dial can be configured to allow manual ISO settings in real time. The factory settings include that function for the modes S, A, and M. Turning the dial will cycle through all setting values available in the ISO menu. That means that Auto ISO can also be selected.

FLOATING ISO
This function complements Auto ISO. Light strength changes with many zoom lenses when the focal length is changed. Floating ISO will in this situation adjust the sensitivity in fine graduations and will simultaneously ensure that the selected settings of aperture value and shutter speed remain constant in (semi) automatic exposure modes. This will specifically in video shootings prevent visible jumps in brightness.
Factory setting: On

• Select Floating ISO in the main menu
• Select On

Notes

• Floating ISO can work only if the original ISO setting allows scope for change, i.e. the highest/lowest ISO setting is not already being used. The Floating ISO warning icon will be displayed in that case.
• This function is not available in Cine mode.
• Floating ISO will be deactivated during shooting if Auto ISO –
  Lock is enabled. The ISO value will locked in during shooting.

PERSPECTIVE CONTROL

This assist function displays a frame showing the expected cropped section of the image after a correction of the perspective of vertical falling lines. Perspective Control helps to achieve a generally straighter vertical line and straight horizon, which ensures
a natural image  effect, specifically in architectural images.
The function “Perspective Control” calculates the image section and the required distortion correction based on the actual panningangles of the camera and the lens used. In effect, the camera orientation during shooting (determined by internal camera sensors) is the decisive factor and not the lines visible in the image object. The function is therefore unlike automatic perspective control features used for post-editing, which are generally based on the image content.
The functionality depends on the image file format used (JPG or DNG). For JPG format images, the correction occurs directly in the camera and the corrected image is stored. For DNG format images, the relevant information is written to the meta data of the original image. Image correction is done later on using a program like Adobe Photoshop Lightroom® or Adobe Photoshop . Factory setting: Off

Notes

• In case of large panning angles, the distortion correction needed for a complete perspective control would be too extreme. That is why this function is automatically skipped or only partially used where angles are too large. In that case, we recommend  creating DNG format images and effecting the desired corrections in a post-editing step.
• While Perspective Control is active, the auxiliary displays for Level Gauge, Histogram and Grid, as well as the function Auto Review will be temporarily disabled.
• Multi-Shot is unavailable in Perspective Control.
• Continuous Shooting options: with SL2 for 2 fps and 6 fps, SL2-S for 2 fps and 5 fps.
• All data edits will be written to the meta data of DNG images, even if the function is deactivated. A special tag will be added if the function is enabled, which will recommend corrections for supported image editing software.
• Select Perspective Control in the main menu
• Select On

WHITE BALANCE (IM VIDEO MODE)
In white balance ensures neutral color rendering in any light. White Balance relies on the setting made in the camera, which light color is to be rendered as ‘white’.
Five methods are available:

• automatic control
• automatic control with lock function
• fixed presets
• manual setting via metering
• direct setting of the color temperature
  Factory setting: Auto

Notes

• During video capture, the white balance can be modified via the FN button or the thumbwheel.
• You can toggle between Auto and Auto – Lock, or switch to another fixed color temperature. However, you cannot switch from a fixed value to Auto during video capture. In that case, the Auto – Lock function will be grayed out.

Notes on white balance during HDMI output

• Automatic white balance cannot be applied to HDMI RAW outputs. White balance will automatically be set to Daylight if HDMI RAW output is activated, while automatic white balance is enabled.

TOUCH AF (IN EVF MODE)
Touch AF is deactivated by default when EVF is in use to prevent accidental repositioning of the focus frame. Touch AF can, however,also be used in EVF mode.
Factory setting: Off

• Select Camera Settings in the main menu
• Select Touch AF in EVF
• Select On/AF Quick Setting only/Off

3 size increments for the focus frame are available.
Double tap:
Moves the focus frame back to the center.
AF Quick Setting only| Long press:
3 size increments for the focus frame are available.
Off| Double tap:
Moves the focus frame back to the center.

Note

• The settings described in this chapter apply for both photo and video mode.
