Shortest possible minimum focus length

Hi, I am trying to build a camera that can capture a 2" x 2" surface at the minimum focus length possible. Which camera module and lens do I need? I don’t know anything about cameras, so I could use some guidance. This is for taking pictures, not video.

Thank you!

Hi, what you want to do requires a macro lens. M12 doesn’t really have this. The wide angle lens will be your friend here. But, it’s going to see a lot more area than 2"x2".

The zoom/telephoto lenses can’t see anything close up. E.g. the longer the focal length the longer the required minimum distance.

Thank you!

Hi, is this still the correct, that there are no M12 macro lens? Or there’s no M12 macro lens for the H7 R2?

Hi,

It’s possible that one exists. However, I have not seen any for cheap. I’d talk to Edmunds Optics if you are serious about finding one.
