Megapixel rating on S-Mount/M12 lenses?

5 years 4 days ago #639951 by TomMaier
Hello,

I am trying to build a 180 degree vr camera. For that I want to get two cheap action cameras with 4K video and swap the lenses for 180 degree fisheye lenses. While searching for S-Mount lenses that would fit I noticed, that a lot of them have a Megapixel rating of 5. How can a lens have a resolution? Will I only get 5 MP if I use a 5 MP lens? How do the actioncameras that actually have a 180 degree lens and more than 5 MP do it?

-Tom

That number is meant to imply that any greater sensor resolution will be wasted with that lens. Or, read another way, that the lens does not have great image quality.

You need to figure out what your use case is, and what you require to meet your goals. Not everyone needs 24MP per image.
