Built-In Diopter correction with Eye Control Focus?

Discussion in 'Modern Film Cameras' started by mike_sowsun, Oct 25, 2019.

  1. The canon EOS A2 has built-in diopter correction while the EOS A2E does not. This was apparently due to the A2E having Eye Control Focus.

    My EOS 7NE has both built-in diopter correction AND Eye Control Focus....

    Did the technology change or was it just an over precaution with the A2E?
  2. I have shot the Canon EOS 5, which is the world-wide version of the A2E. LINK However, it is now buried in my cabinet without batteries and I can't lay my hands on it right now. I tried looking at the manual for that model at (Butkus) for diopter control, but couldn't find what you're asking about. Unfortunately, Butkus's copy is not 'text', making search impossible.

    You are, I suppose, aware that the rubber eye cushion covers up the diopter wheel on many Canon EOS models.

    Sorry not to be of more help.
  3. The diopter correction on the the A2 is actually a slider and it is also buried under the rubber eyepiece. The EOS A2E, EOS 5, and EOS 3 all have Eye Control focus but no Diopter control.

  4. Why not lack of space instead?
    I have no clue why EOS 5 eye control worked fine in both orientations(!) for a friend wearing aproximately +8 glasses but not for me (contacts) or another +3
  5. As for the differences in the EOS 5, one of the founding fathers here (Greenspun) put it:

    but the link to that review here on P.net seems to have gone dead. I recall there was a similar problem with the vertical/horizontal thingie.
