@Gleep52 hi, did you ever take a swing at doing a teardown and making focus adjustments? If so, would you consider sharing a process for that? Thanks!

  @DrDealgood in fact I did - and it wasn't hard at all.  The hardest part was the focus after removing the glue - turns out, it's VERY sensitive to even the tiniest amount of rotation of the lens would greatly throw off the focus.  I turned it quite a bit when I got the glue off - and because of the nature of the pins and construction - to get it power, you have to put the two halves back together and then you can't easily adjust the focus without taking away power to pull the two halves apart and twist again.  I ended up using some sticky tack (poster tack?) to squish onto the front of the lens when the unit was partially together and on so I could twist the poster tack and see my focus a bit easier than continually powering it off an on a bunch of times.  Here's a bunch of pics of the innards and how close the focus was on my knuckles in one of the shots on the A1 mini's print bed.  Great little camera.  I've got 8 of them now.  lol
