- What DISTANCE will the camera be placed from the object(s) to be viewed?
- How much AREA do you want to view on screen around the object(s) to be viewed?
- How much DETAIL do you want to capture?
A lens that will give you a wider viewing angle, such as a 4mm lens, will offer you very little in terms of detail. However a 12mm or 25mm lens, which will give you great detail, will not cover a large area since the field of view is narrowed.
The table below shows the area the camera will cover on the screen.
Real Examples
Each of these images were captured from 10 metres from the car. Note how the DETAIL and AREA covered
by the camera changes depending on the lens size.
