In the short focus range (near subjects) all 3 pics are focused fine.
When it comes to mid (above 1-1,5 mt) and far subjects the 2° pic of series isn't focused like 1° and 3°. The blur (out of focus) is more visible on 2° pic with far subjects.

BTW I'm sorry to give you all this hassle with my camera. Surely its focus bug isn't CHDK related. Maybe an issue with my ixus ... that luckily doesn't occur out of CHDK.
So, let it be. I am more than satisfied with everything else i got from CHDK.
Thanks for the test report. My worry is that it's not just your camera. Zeno (Dave) now reports "focus at infinity" problems with his S100 despite running the focus test script successfully yesterday. I'll keep chasing this.

@fabri22: there is one more thing we can try. If you go to the Canon tools menu and select "reset all" to put the camera into factory default mode and then rerun the focus7.lua test, does it work any better?

I did it prior to report here those results.

I was misled too by the large DOF of these cams at beginning of the "set_focus" testing many days/posts ago.

... at least, if you'll keep chasing this, it isn't my fault only.  ;)

In the case of the S100 problem, it's not a question of DOF and maybe the focus being good or maybe not. Any focus setting out past about 1m makes everything in the picture fuzzy - nothing is even close to being in focus.

Your findings or Dave's findings ?
Just tried your last test script with IS off (your "fuzzy" sounds like an IS issue). No good news here.

A fellow named Jym over on one of the KAP forums actually.

Hi waterwingz, I finally got to getting aquainted with your MF_test.lua script.

I decided to start from the bottom of your list of missing cameras and so I picked the TX1.

Probably not the easiest choice, we'll see.

  1) I set the camera to Manual mode (I suppose that is P)
  2) I didn't find a camera MF mode but found AFL and made sure it was off
  3) I didn't figure out how to disable Continuous AF and Servo AF modes
      The TX1 camera menu lets me switch between Single and Continuous AF but that's all.
      (www.manualowl.com/m/Canon/PowerShot-TX1/Manual/38064?page=47)
  4) I turned lua native calls on.

Since I couldn't figure out how to disable Servo AF on the camera menu I tried looking at the propset and using CHDKPTP but didn't succed with that either.

I tried =return get_prop(293) and got:
3:return:23

I then tired =set_prop(293,0) which crashed the camera and I gave up.

Anyway running the test script with as good settings as I could get (Servo AF was still on) I found that test 2) and 4) crashed the camera. So I disbaled them. The result CSV is attached.

Did I miss anything with the Servo AF or can I go on to further cams?

Thanks - it's a bit exciting to have somebody run these tests who will likely do more than one camera and thus be an "experienced" tester.

I took at quick look at the manual - things were different with older cameras so this seems to be as good as it gets.

Normal.

Single AF should have done it for you.

Good.

Sadly, those props tend to be "read only".

Test log looks good.  Certainly as good as any of the other 98 camera test results reported so far.  Thank you for that !

Please continue.  The servo_AF recommendation is "wisdom of the crowd" thing - I have not collected data to determine how much it really matters.

Ok that's what I used.

Good. I'll disable it where it's available.

Here is the S2IS csv. Didn't crash, several things report failure.
Camera ends up with MF enabled after the test run.
