Various video lenses can be attached to the HVR-S270U and HVR-Z7U, which are both equipped with a universal standard 1/3-inch bayonet mount mechanism for quick changing of lenses.
✜Carl Zeiss Lens for HD Video as Standard
A high-quality, multi-purpose Carl Zeiss lens for HD video comes as standard with the HVR-S270U and HVR-Z7U. Stunning resolution and contrast is achieved thanks to the Carl Zeiss Vario-Sonnar™ T* coating, which suppresses unwanted reflections. A specially designed wide-angle lens is also available as an option, to suit a diverse range of shooting requirements.

✜Easy-to-use Interchangeable Lens for Fixed-lens Camcorder Users
These lenses give Sony’s two new HDV camcorders the same functionality as popular fixed-lens camcorders like the HVR-Z1U and HVR-V1U, thanks to built-in features such as auto-focus, optical stabilizer, and automatic back-focus adjustment.
Current users of the above camcorders will easily become adept at using the HVR-Z7U and HVR-S270U, even if they have never used interchangeable lenses.
✜Natural-touch Lens Operation
Focus
The newly designed focus ring offers two types of manual focus, plus an auto focus mode that can be easily switched by sliding the focus ring forward or backward.
When the focus ring is in the front position, the lens works in the same way as the HVR-Z1U, HVR-V1U, and DSR-PD170. In this case, either manual or auto focus mode can be selected by the assignable button on the lens. On the other hand, when the focus ring is set to the rear position, the focus ring has a physical stop at infinity and works in the same way as a professional interchangeable lens, with fixed-focus-position and distance indicators.
Zoom
Fast, intuitive manual-zoom response is provided by an internal gearwheel mechanism that provides accurate zoom positioning. A high-quality servo-motor provides the smooth zooming performance that industry professionals have come to rely on.
Iris
The iris ring encircles the lens barrel.
Manual iris adjustment is possible with an ENG-type ring system that allows fine exposure control for challenging lighting situations.
