    Peter,

    The MF safety is now off.  Going through the G9 manual shows that There are two custom setting memories (C1 & C2) that saves settings of aperture, speed, focus, flash etc. but not ISO. This seems to be fixing focus at infinite. If it holds then I will be able to conduct a calibration. Fingers crossed.

    Hi Greg,
     

    ... the manuel focus doesn't allow the camera to be locked in at infinite focus :(

    I remember going through all the menus and settings for the SX160, so I took the liberty of downloading the G9 manual to see what's up.  Do you by chance have "Safety MF" set to "on" as shown on page 126?  If so, the half-press of the shutter button will be touching up your focus, which is exactly what you don't want.
     
    Sometimes the focus can be set to slightly past infinity, so you might want to back off a tick or two to see if things get any sharper.  (As a data point, though, the proper setting on my SX160 was right at infinity.)  You'll want to be shooting at the aperture that maximizes your resolution (since there's plenty of light); this is typically stopped down one stop or maybe 1.5 stop for prime lenses, but I'm not sure if this rule-of-thumb holds for small zooms.
     
    Cheers,
    Peter

    What is NavList?

    NavList is a community devoted to the preservation and practice of celestial navigation and other methods of traditional position-finding. We're a group of navigators, navigation enthusiasts and hobbyists, mathematicians and physicists, and historians interested in all aspects of navigation but primarily those techniques which are non-electronic.

    To post a message, if you are already signed up as a NavList member, start a new discussion or reply to any posted message and use your posting code (this is a simple low-security password assigned when you join). You may also join by posting. Your first on-topic messsage automatically makes you a member, and a posting code will be assigned and emailed to you for future posts.

    Uniquely, the NavList message boards also permit full interaction entirely by email. You can optionally receive individual posts or daily digests by email, and any member can post messages by email (bypassing the web site) by sending to our posting address which is "NavList@NavList.net". This functionality is similar to a traditional Internet mailing list: post by email, read by email, reply by email. Most members will prefer the web interface here for posting and replying to messages.

    NavList is more than an online community... more about that another day.
