- | Unfortunately not - one change we decided to make in the hardware revision process was to choose a new, integrated camera and sensor package. The advantage of the new setup is a lack of pincushion distortion, and a small resolution boost. Also, a factory focused lens and much smaller size (something we got frequent requests for with the original Pixy). | + | It depends on which version of Pixy2 you have. Pixy 2.1 has a replaceable M12 lens, but Pixy 2.0 does not. |
- | The new camera does have a slightly smaller field of view - 60 degree horizontal, and 40 degree vertical - but a higher framerate (60 fps). | + | You can use practically any M12 lens with Pixy 2.1 as long as it has an IR-cut filter. (The IR-cut filter is something all CMOS sensors need to eliminate most of the ambient IR light, which can adversely affect the color fidelity.) Pixy 2.1 ships with a 1.7mm focal lengh F2.0 lens, which gives it an 80-degree horizontal field of view. |
