  5. Problems you were having?

    N/A

  7. Troubleshooting attempts you’ve made?
    focused as close up as possible

  8. What help do you need?

We are testing a variety of cameras with the 4 * multicamera synchronous HAT. However both the 16MP and 64MP one have a minimum focus distance of 8cm. We have B0182 which has a minimum focus distance of 5cm which is good for us but it uses up one channel on the raspberry pi. Is it possible to either hack the 64MP camera (or the 16MP camera on the 16MP version) to have a shorter minimum focus or get the B0182 modified Raspberry Pi camera working on the 4 * camera HAT?

Thanks.

Cheers,

Neil
