2) Selecting lens
Overall camera lens make performance is largely affected by the lens. It is recommended to
check the following points beforehand.
• Ghosting can occur by using a lens with a large image area (e.g. 2/3 or 1/2 inch for HV-D37A).
Use a 1/2 inch lens for HV-D27A and 1/3 inch lens for HV-D37A.
• Vertical color shading can occur if the lens has a short exit pupil length.
• If the lens is used at nearly fully open iris, resolution is sacrificed, while such problems as
shading and flare can detract from the image quality.
