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.
The flexible bayonet lens attachment system allows you to use a wide range of lenses.
Standard 1/3-inch HD video lenses, from manufacturers such as Fujinon and Canon, can be attached directly to the HVR-Z7U and HVR-S270U.
If you’d like to attach a 2/3-inch or 1/2-inch HD video lens on the HVR-Z7U or HVR-S270U, it is possible to do so by adding a standard lens adaptor from the lens manufacturer.
The HVR-S270U and HVR-Z7U camcorders have 12-pin lens connectors allowing compatibility with professional ENG lenses.
This feature is very useful not only for those who already have these professional HD video lenses, but also for those who prefer to use HD digital cinema lenses for their unique contrast, color, and atmosphere.
With a special adaptor from Sony, it is also possible to use the lens series designed for Sony Digital SLR still cameras.
By using lenses in various configurations, creative effects can be achieved.
This approach is ideal for filmmakers on a budget or those who already own lenses.
The focal length is doubled with a 2/3-inch lens adaptor
The focal length is increased 1.3 times with a 1/2-inch lens adaptor
The focal length is increased 7 times with an lens adaptor
Some lenses may not be compatible and not all lens functions may be available
*4 These values are calculated to be equivalent to 35 mm film.
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.
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.
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.
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.
