sony optical zoom

Some super-telephoto Sony lenses support optional 1.4x and 2.0x teleconverters. In the examples given, a 2.0x teleconverter is noted to extend reach up to 1600 mm.

Video-focused Sony zoom lenses commonly provide independent zoom, focus, and iris rings, plus a servo/manual zoom option or power-zoom lever for smooth electronic zooming. Additional controls include aperture click switches and zoom-lock or focus-hold switches for precise manual operation during video work.

The selection includes dedicated power-zoom designs—for example an 18–110 mm Super 35/APS-C power zoom and a full-frame f/4 16–35 mm power-zoom that offer smooth servo and manual zoom control for video work.

Typical handling features include separate focus, zoom, and iris rings for manual control; internal-focus/internal-zoom and constant-length designs for stable balance; zoom-lock switches and focus-hold buttons; and dust- and moisture-resistant construction for improved reliability in challenging conditions.
