  • Love all the new features since I last had a lens to calibrate (way back on version!).

    I am having an issue with a 5D Mk II and a Canon 70-300 f/4-5.6 L IS – the auto cal won’t run using RAW conversion, only runs using jpgs. I wanted to try the new more accurate cal as this is a new lens and I am having some issues with it focusing well at infinity focus at the long end at least and wanted to make sure I had the AF microadjustment set as well as possible before dciding the lens has issues.

    • Hi Robert – have you tried the alternate link on the licence page too?
      We’re not seeing any errors here – have you checked for any firewall software that might be blocking your connections?
