Canon viewfinder magnifier hunt

Discussion in 'Canon' started by Siddhartha Jain, Apr 13, 2005.

  1. Hi,

    I am looking for a viewfinder magnifier to aid manual focus on my Canon
    300D. I measured the viewfinder on my 300D and its ~23mm wide. Then I
    measured a friend's Pentax MZ-50's viewfinder and its also ~23mm wide.
    So will the Pentax FB 2x magnifier fit the Canon 300D?

    Generally, will any magnifier that can fit a viewfinder that is 23mm
    wide work on the Canon 300D?

    Years ago I had a Pentax diopter correction eyepiece which fit my Canon
    (23mm) square (actually rectangular) viewfinders. Whether the one shown in
    your B&H link measures the same as the Pentax manual focus isn't indicated.
    Also note: the Canon Magnifiers don't have adjustable diopter focusing.
    Another consideration: Canon also had (still have?) the "Angle Finder B",
    which does allow diopter adjustment.

    See here:


    and here:
    This one shows the "Adapter S" attached

  3. Ok, I made some errors in measurement. I erroneously measured the outer
    edges of the viewfinder. Now, I took off the plastic mount on which the
    rubber relief is mounted. I measured distance (horizontal) between the
    inner edges of the plastic mount. Its 18.5mm for the Canon 300D and
    19mm for the Maxxum 5. I tried interchanging the plastic mounts to
    confirm for size but they don't slide in because the plastic mounts for
    each have slightly different design. Unfortunately, I don't have
    precision measurement tools like a vernier calliper to get the exact

    Now, from an eBay posting I discovered that the magnifier for the
    Pentax K mount and screw mount series are also 18.5mm wide!!

    Thats good because I almost bought a yashica magnifier thats 23mm wide
    off eBay. In the last 10 mins, my internet connection gave up and I
    couldn't bid for the auction :)

    As for the Canon Angle finder, thats expensive - both B & C. Besides, I
    don't want an angle finder. The Canon Magnifier S with adapter S turns
    on eBay every now and then and goes upto $60 easily. The Pentax and
    Yashicas sell for much less - typically under $20.

    An eBay seller posted the Yashica as having 23mm width.

    I also came across this reference that says Minolta Angle Finder VN
    fits where Canon Angle finder C does.

    So the adapters have to be the same size and that means whatever fits
    Canon should fit Minolta and vice versa.

    I'll be glad if someone can confirm my measurement because I am in
    India and can only see the magnifiers on eBay or online stores.

    What about the Canon Anglefinder C which has magnification and will
    definately fit all EOS (plus some FD) Canon bodies, with one of the two

  5. The Angle finder C is good but I don't want an angle finder and Angle
    finder C is too expensive. Retails for about $170.

    Short answer - $$$$$$$$. Plus the inherent angle which may not be practical
    for the subject and shooting angle.

    The problem is more likely the "style" of focus screen used more than
    anything else. They choose to use a fine grained/brighter screen assuming
    most users rely on AF and would like the brighter screen. When I was camera
    shopping I saw why some of the competition's screens were reviewed as being
    "dimmer", they use a screen that allows easier manual focusing.. There is
    more to focus screens and finders than just being extra bright yet
    reviewers only seem to note the brightness, not how well you can see the
    focus point.
