  • Canon A1 and A1s/Auto focus or instant focus. Which is better and why?

    Posted by Bruce Pelley on August 18, 2011 at 4:22 pm

    Gents,

    At times during last few shoots, I have had considerable and unexpected focus issues with an A1 in a location (and from roughly the same spot) that previously did not have any problems whatsoever!

    Currently I am at a loss to explain or justify it as it unpredictably occurs on and off. The focus drifts while shooting live with no hands on the camcorder. Now the focus is unreliable.

    I have the focus set to I.F because between church segments I barely have time to be at the right place at the same time, frame the subject and press the record button nevermind adjust the focus manually each and every time. This state of affairs need to be resolved. Please, I need your help. I hope something isn’t gone wrong with the optics system!

    Which leads me to my questions:

    1) What are the pros and cons of each when using auto focus versus “instant” focus?

    2) Which is the most/more appropriate mode given the situation/circumstances and setting as stated above?

    What would you try to resolve the problem?

    Should I switch to auto mode and what possible ramifications would that have other than to presumably focus a tad slower?

    All responses, suggestions, input and thoughts on the matter are welcomed.

    Thanks in advance

    Seasons Greetings,

    Thanks for your interest.

    I did get some response in another major video forum but nothing here. It’s been a long time since I read it.

    I think part of the problems was that the A1 I was using need to go back to the factory to be serviced.

    Situation has greatly improved since that occured.
