Hello, great tutorial, a couple of questions please.

[Daniela Morescalchi]

1. What are the different focal lengths? I had tried “focal length: optical center”, how do you decide which is better?
2. I have Google Pixel 3a xl how would translate this “1.4μm pixel width ” for blender?
   Thank you again, great succinct tutorial!

Hi Daniela as long as we’re waiting for an answer from someone who knows what he/she is talking about, I don’t think that a phone camera has a physical focal length (wouldn’t know where it would fit…), but according to this https://www.dxomark.com/google-pixel3-camera-review/ yours has an equivalent of a 28mm focal length.

@spikeyxxx  Thank you. I had looked up the specs on line, but they didn’t seem to translate. I appreciate the clarifying article!
