Q: 7. I'm intrigued by many raving reviews on the image quality this lens can produce. I noted that the official description stated improved auto focus performance. I wonder if the statement applicable to continuous autofocus for video. Particularly on S5, S1, S1H bodies, and compared to Lumix 50mm/f1.8 lens? If the solid improvement exists, many will opt for getting this lens, for this reason alone.

A: The Panasonic Lumix S PRO 50mm f/1.4 Lens has two focus motors - linear and stepping - which allow it to achieve fast focusing for both still photography and video recording usage needs and would have substantial performance increase in comparison to the Panasonic Lumix S 50mm f/1.8 Lens.

Q: 8. 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.

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: 10. Is the focus breathing of this lens minimal or substantial, when racking focus between subjects?

A: The Panasonic Lumix S PRO 50mm f/1.4 Lens exhibits minimal if any focus breathing.
