With the LUMIX S 35mm F1.8 (S-S35), Panasonic now presents the fourth lens in its own full-frame prime series for the L-mount. It should actually be the last of four fast fixed focal lengths with F1.8 aperture (24mm, 35mm, 50mm, 85mm). However, another 18mm model has already been announced.
All four F1.8 lenses share a common size and position of controls - as typically expected from cine lenses. This means that changing lenses (on a gimbal, for example) does not force a reset of the entire camera setup. Thanks to the same lens diameter, filters can also be used together.

The Panasonic LUMIX S 35mm F1.8
Thanks to its compact dimensions (approx. 8.2 x 7.4 cm) and low weight (approx. 295 grams), the LUMIX S 35mm F1.8 is much handier than many older L-mount lenses from Panasonic. Like all models in this series, the 35mm F1.8 features a dust- and splash-resistant design that can be used in temperatures between 40° and -10° C, even in adverse conditions.
The filter diameter is 67mm and its 9-blade circular aperture is said to provide an attractive bokeh effect with smooth sharpness-blur transitions. In addition, the lens is said to have been optimized for minimal focus breathing. The closest focusing distance is 24 cm.
When using manual focus, a non-linear or linear setting can be selected for the focus ring. In the non-linear setting, the focus is shifted by a variable amount according to the rotation speed of the focus ring, e.g. to switch more quickly between focus areas. In contrast, in the linear setting, the focus is always shifted linearly according to the angle of rotation of the focus ring. The entire focus range can be traversed in 90 to 360 degrees (adjustable in 30 degree increments) in the linear setting.
The LUMIX S 35mm F1.8 is scheduled to be available in stores by the end of November 2021. The recommended retail price is 679 Euros. It has not yet been communicated when the 18mm lens will appear as the fifth in the bunch of this prime series.
