Panasonic Lumix S 18mm f/1.8 Lens

Uncompromising Optical Design

This fast f/1.8 lens is comprised of thirteen lens elements in twelve groups. It includes three aspherical elements, three extra-low dispersion elements, one ultra-extra-low dispersion element, and one ultra-high refractive index element. This advanced design effectively suppresses chromatic aberration, while also achieving high descriptive performance and beautiful bokeh. The ultra-wide angle of view makes this lens suitable for a wide range of imaging situations including landscapes, astrophotography, and architectural photography. It can also be used for close-up shots thanks to the minimum focusing distance of about 7".

Smooth and Silent Operation

The LUMIX S 18mm F1.8 is capable of smooth, silent operation to work with the camera’s high-speed, high-precision contrast AF system with the sensor drive at max.240 fps. For the non-linear setting, the focus is shifted with a variable amount according to the rotation speed of the focus ring. In contrast, the focus is shifted with a designated amount according to the rotational quantum of the focus ring for the linear setting. Sensitivity (the amount of focus shift per rotational quantum) can be selected from 90 to 360 degrees by 30 degrees to enable the intended focus operation. The LUMIX S 18mm F1.8 also excels in video recording performance with a mechanism that suppresses focus breathing, a fatal problem of all interchangeable lenses designed for still image photography. Together with a micro-step aperture control for smooth exposure change, professional-quality video can be recorded.

Compact and Lightweight 

Weighing approximately 12-ounce, The compact size and lightweight Panasonic Lumix S 18mm f/1.8 Lens features stunning mobility to fit the S5, LUMIX’s smallest full-frame model. The rugged dust/splash-resistant design withstands use under harsh conditions even at 14 degrees Fahrenheit for high mobility. The filter diameter is 67 mm, with a 9-blade circular aperture diaphragm.

3. Is the lens weather-sealed?

Yes, it features a rugged dust and splash-resistant design that can withstand harsh conditions and operate in temperatures as low as 14 degrees Fahrenheit.

4. What is the minimum focusing distance?

The minimum focusing distance is approximately 7 inches, allowing you to capture unique close-up shots with a wide background perspective.

5. What size filter does this lens take?

The lens features a 67mm filter thread, making it easy to attach ND, polarising, or protective filters.

How to Use / Care Instructions

Application Scenarios: Use the ultra-wide 18mm perspective to capture sweeping landscapes or tight architectural interiors. For videographers, take advantage of the linear focus setting to perform repeatable, precise focus pulls on a gimbal or tripod.

Care Instructions: While the lens is dust and splash-resistant, always use a soft microfiber cloth to clean the front and rear elements. Attach a 67mm protective UV filter to safeguard the front element from scratches during fieldwork. Store in a dry, cool environment when not in use.
