Frequently Asked Questions (FAQs)

1. Are C-mount lenses good?

C-mount lenses are known for their high optical performance and precise focusing, resulting in detailed and sharp images. They are particularly suitable for industrial applications with fixed imaging parameters due to their fixed focal length.

2. What is the difference between C-mount and CS-mount lens?

The main difference between C-mount and CS-mount lenses is the flange focal distance (FFD). C-mount lenses have an FFD of 17.526 mm, while CS-mount lenses have a shorter FFD of 12.5 mm. The shorter FFD of CS-mount lenses allows them to be placed closer to the camera sensor.

3. What is the advantage of C-mount camera?

C-mount cameras offer several advantages, including the ability to cover distances beyond 40 ft by using special lenses. They are also adaptable to changes in technology and are effective for indoor use.

4. Do CS mounts work on C-mount?

CS-mount and C-mount components have the same threads, but lenses and cameras of different mount types should not be directly attached. The difference in flange focal distance (FFD) between the two mounts will cause the lens' focal plane to not coincide with the camera's sensor plane, resulting in blurry images.

5. What are the disadvantages of APS-C camera?

Some disadvantages of APS-C cameras include not being able to compete with full-frame cameras in terms of image quality, the crop factor causing additional magnification, and difficulties in achieving bokeh with the same focal length lenses.

6. What are the disadvantages of C-Mount CCTV cameras?

One disadvantage of C-Mount CCTV cameras is that they require more effort to be installed outdoors compared to other CCTV cameras. They are more sensitive to external factors such as rain, heat, wind, and snow, making them less ideal for outdoor use.
