Lens comparison

[Harjit Singh]

As I was designing and building my machine, I wasn't sure what focal length lens to pick.

I got f6.0mm, f8.00mm, f12.00mm, all 1/2.7" lenses, used the same camera, same target, same lighting conditions, and took the attached pictures.

The camera is equivalent to this one: https://www.amazon.com/dp/B08LHCJ8F5

1MP USB HD Camera Module, OV9281 Camera with 100° Wide Angle, Black and White Global Exposure, Face Recognition, QR Scanning for WinXP/Win7/Win8/Win10/OS X, for Android

In the pictures, the BGA is an: TFBGA 100-ball, 8 x 8 mm, 0.8 mm pitch fine pitch ball grid array package.

The QFNs to the bottom left are: TI S-PVQFN-N20 or VQFN-N20. 20 pin, 0.65mm pitch

The part to the diagonal right is: Atmel 8MA1 - UDFN. 6mm x 5mm, 8 pin, 1.27mm pitch.

Messages are limited to 8MB. So, I'll reply to this email, and add the pictures to meet this limit.
