Lens selection

1)Optical characteristics

The proper lens is vital for obtaining full performance from the camera. The exit pupil distance is particularly important for a 3 CCD type camera. If too short, vertical color shading can appear in the picture.

Also, as the lens iris approaches fully open, problems such as loss of resolution, shading and flare (overall image "white-out") can detract from picture quality. When using in applications that call for open iris, the lenses for 3 CCD are recommended. If another lens is contemplated, check the performance beforehand.

2)Auto iris lens

Main types are Video (with self contained iris amplifier) and DC (DC voltage applied to open lens iris) and manual over-ride (e.g., Cosmicar). Lenses without self-contained iris amplifier are not compatible.

Camera settings differ according to the auto iris lens type (see page 20).

Note: The HV-D30 uses lens connector wiring prescribed by the EIAJ (Electronic Industries Association of Japan). Refer to page 47
