Introduction
This manual provides essential information for the safe and effective use of your Panasonic LUMIX S 35mm F1.8 Leica L Mount Lens (Model S-S35). Please read these instructions carefully before using the product and retain them for future reference.
The LUMIX S 35mm F1.8 is a versatile prime lens designed for L-mount full-frame digital cameras, offering high resolution and beautiful bokeh. It features a compact, lightweight, and rugged dust/splash-resistant design, making it suitable for various photographic conditions.
Setup
Attaching the Lens
- Ensure both the camera and the lens are powered off before attachment.
- Align the mounting index on the lens with the mounting index on your L-mount camera body.
- Rotate the lens clockwise until it clicks into place. Do not force the lens if it does not attach smoothly.

Attaching Filters
The lens supports filters with a diameter of 67mm. Gently screw the filter onto the front of the lens until secure. Avoid overtightening.
Operating the Lens
Focusing
The S-S35 lens features a manual focus ring. You can program the rotation of the manual focus ring to control the focus throw, allowing for precise and seamless transitions between infinite focus and close focus. Refer to your camera's manual for specific settings related to programmable focus throw.
The minimum focusing distance for this lens is 0.24 meters (0.79 feet), enabling close-up shots.

Aperture Control
The lens has a large F1.8 maximum aperture, allowing for excellent low-light performance and shallow depth of field. For video recording, the micro-step aperture control ensures smooth exposure changes, preventing abrupt shifts in brightness.
Video Recording Features
The S-S35 is optimized for video recording with a mechanism that effectively suppresses focus breathing, maintaining a consistent angle of view when adjusting focus. This feature, combined with smooth aperture control, contributes to professional-quality video capture.
Maintenance and Care
Dust and Splash Resistance
The lens features a rugged dust and splash-resistant design, providing protection against light dust and moisture. However, this resistance does not guarantee that damage will not occur if the lens is subjected to direct contact with dust or water. Always take precautions when using the lens in challenging environments.

Cleaning the Lens
- Use a lens blower brush to remove dust from the lens surfaces.
- For smudges or fingerprints, use a clean, soft microfiber lens cloth with a small amount of lens cleaning solution. Apply the solution to the cloth, not directly to the lens.
- Never use abrasive materials or harsh chemicals to clean the lens.
Storage
When not in use, store the lens with both front and rear caps attached in a dry, cool place away from direct sunlight and extreme temperatures. Consider using a desiccant to prevent mold growth in humid environments.
Troubleshooting
General Issues
- Lens not attaching: Ensure the lens and camera mounting indexes are correctly aligned and that no obstructions are present. Do not force the lens.
- Focus issues: Check your camera's focus mode settings. If using manual focus, ensure the focus ring is rotating freely and that programmable focus throw settings are configured as desired.
- Image quality concerns: Ensure the lens elements are clean and free from dust or smudges. Verify that the lens is securely mounted to the camera body.
If you encounter persistent issues not covered here, please refer to your camera's instruction manual or contact Panasonic customer support.
