Question: How do I determine the correct lens or correct lens setting for the scene field-of-view (FOV)?
Answer:
The A-C3BMH and A-C4CMH cameras feature a CS-mount compatible lens mount with the
A-LTV2Z3314CS 3.3-8mm vari-focal lenses already attached. The following is a chart to use to help determine the correct lens or correct lens setting for the scene field-of-view (FOV). |
