Hitachi HV-D27A, HV-D37A operation manual Lens selection

Lens selection

CAUTION:

Observe the dimensions of the lens mounting selection as illustrated at the right.

If the dimensions are not observed, do not use such a lens, because the lens and the camera will be damaged

Flange surface of lens

3.8mm or less (HV-D27A) 4.3mm or less (HV-D37A)

(1)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.

(2)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.

(3)Image ghosting can occur if the lens is not matched to the CCD. Choose 1/2-inch for the HV-D27A and 1/3-inch for HV-D37A.

(4)The camera dose not include flangeback adjustment. Depending on the type, focus might be imperfect at the telephoto and wide angle extremes of a zoom lens.
