A staple of wide-angle versatility, the Panasonic Lumix S PRO 16-35mm f/4 Lens UV Filter Kitfrom Panasonic Lumix S PRO 16-35mm f/4 Lens UV Filter Kitis an L-mount wide zoom featuring an f/4 constant maximum aperture. An optimized optical design incorporates a series of aspherical, low dispersion, and high refractive index elements, to control a variety of aberrations, color fringing, and distortion for sharp, clear, well-corrected imagery throughout the zoom range. Complementing the optics is a unique double-magnet linear motor focus system, which provides high-speed response and power while remaining compact in size. The lens also sports a rounded nine-blade diaphragm, which contributes to the quality of bokeh, and a weather-sealed construction to suit working in a variety of weather conditions.

L-Mount Lens/Full-Frame Format    Aperture Range: f/4 to f/22    Three Aspherical Elements    One ED Element, One UHR Element    Double-Magnet Linear Motor AF System    Weather-Sealed Construction    Rounded 9-Blade Diaphragm    77mm UV Filter

Wide-angle zoom is designed for full-frame L-mount mirrorless cameras, however can also be used with APS-C models where it provides a 24-52.5mm equivalent focal length range.

Constant f/4 maximum aperture maintains consistent illumination throughout the zoom range.

Three aspherical elements and one ultra-high refractive index element help to minimize distortions and spherical aberrations throughout the zoom range in order to maintain edge-to-edge sharpness and illumination.

One extra-low dispersion element greatly reduces chromatic aberrations and color fringing in order to produce a high degree of clarity and color accuracy.

The autofocus focus system employs both a double-magnet linear motor to deliver impressively fast and precise focusing performance while remaining compact. A focus clutch mechanism has also been incorporated, which allows for near-instant AF/MF switching.

Splash, dust, and freezeproof design benefits working in inclement weather conditions down to -14°F.

Rounded nine-blade diaphragm contributes to a pleasing bokeh quality.

Related Questions and Answers

Q: 1. Is there a tripod mount for this lens? How to support this on a tripod to relieve the stress of its weight on the camera lens mount? Just letting it hang off the camera, with only the camera body attached to the tripod would seem to weaken the lens mount, especially over time.

A: There is currently no lens support available for the Panasonic Lumix S Pro 50mm f/1.4 lens. While the concern is understandable, there have been no recent reports of such issues happening and such an occurrence is not common today due to more robust mount-engineering practices.

Q: 2. What is the primary difference between this and the "non-pro" lenses. Is the glass the same, but different ring controls?

A: The Panasonic Lumix S PRO 16-35mm f/4 Lens would be the only 16-35mm lens designed for the Leica L-mount lens mount. The closest lens options to the above lens would be the Sigma 14-24mm f/2.8 DG DN Art Lens for Leica L, B&H # SI142428L, or the Sigma 18-50mm f/2.8 DC DN Contemporary Lens for Leica L, B&H # SI185028DCLM. The main difference between the above lens is the Sigma 14-24mm f/2.8 DG DN Art Lens for Leica L would be wider and would be twice as bright as it has a constant f/2.8 aperture. Both the Panasonic and Sigma lens are considered professional lenses from the respective manufacturers. The Sigma 18-50mm f/2.8 DC DN Contemporary Lens for Leica L would be a more economically-priced lens. It has a brighter aperture with a constant f/2.8 aperture and it has a longer optical zoom range, but the optical image quality would not quite be on par as the image quality from the professional lens options listed above. Build quality and optical performance would be main differences between "professional" lenses and standard or entry-level lenses.

Q: 3. Does this lens have a static rear lens element at the mount for better weather sealing?

A: No, the rear element of the Panasonic Lumix S PRO 16-35mm f/4 Lens retracts inside the lens barrel, therefore we recomend keeping the rear cap on if the lens is not mounted on the camera.

Q: 4. Does the lens length change when zooming or focusing?

A: This is going to be very high quality serious amateur professional lens. We suspect that along with the advertised minimal breathing there will be minimal, if any, lens length change.

Q: 5. Will the OIS work on the Leica CL?

A: Yes, as stated previously with the latest firmware.

Q: 6. Is this fully compatible with the DJI RS2 Gimbal?

A: The DJI RS 2 Gimbal Stabilizer can work with most lenses. The support weight is part of the concern. The Panasonic Lumix S PRO 16-35mm f/4 Lens is around 1.1 lbs and the gimbal can support up to 10 lbs. It will work but note, that when you zoom the lens you will need to balance the gimbal each time. Most use prime lenses when using a gimbal or do not zoom the lens.

Q: 7. Will this lens work with the new Phase Detection AF of the S5 ii Lumix camera?

A: Yes Panasonic Lumix S PRO 70-200mm f/4 O.I.S. Lens is compatible with phase detection autofocus in the new Panasonic S5II.

Q: 8. I have the Lumix S 18mm and 35mm f1.8 Prime lenses. Would I be happy replacing both of them with this f4 lens?

A: The Panasonic Lumix S PRO 16-35mm f/4 Lens will allow you to easily zoom, so you won't have to switch lenses but the aperture is narrower at f/4. So it depends if you need the better quality in low light of those 1.8 lenses or f/4 is enough for your needs. If you take many photos in low light situations than you might want to stick with the lenses that you have.

Q: 9. How is it about noise in video in AF-C? Is it without any nise, quiet as f.e. P 24-105/4-it means NO noise in video? Because I bought sigma 50 1.4art l-mount and it was bad idea -audible in every my video with AF-C:-(,thanks a lot!....(panasonic S1H)

A: It should be as good as the 24-105 lens

Q: 10. Does this lens work on leica SL? Someone say after few weeks this lens turn default to MF in leica SL, CL.

A: With a firmware update, this lens should work perfectly on the SL. Just make sure the manual focus clutch is not enabled if you want to use autofocus.
