Bunny Snow		Inserting ED-E eye cup without instructions I am having problems calibrating my eyes (focus and movement) to the Canon Elan 7E. Therefore, when I read that Peter Kun Frary used a Ed-E eye cup which helped him avoid squinting, reduced glare and so forth, I thought that might be the answer to my quest. Upon receiving a second hand eye cup, without instructions, I have NO clue on how to attach it to the present diopter cup location. At his web site, Dr. Frary writes: "For ECF to work, it must be calibrated for your eye. Another person's calibration won't work for you. Calibration is simple: twist the knob to CAL and look at the flashing rectangle while pressing the shutter. Calibrations are cumulative, i.e., the camera learns to track your eye better with each calibration, especially if you calibrate with different lighting and lenses. It took me several dozen calibrations to achieve consistent results. However, once calibrated, ECF was wonderfully fast and reliable in good light. ECF is noticeably faster than the A2E and Elan IIE. There is a gotcha for me: ECF is sensitive to my eye's position relative to the viewfinder (your mileage may vary). If I shift my eye off-center or too close ECF fails, especially during calibration. I decided to install 'a larger eyecup, the ED-E,' to see if it helped. 'The ED-E is a huge eyecup that wraps around your eye and blocks out external light.' It can be rotated for vertical shots or for left-eyed folk. I also like it for its enhanced viewfinder visibility. 'What a difference it made! With the ED-E, ECF proved itself much more reliable for me during daylight shooting. I believe the shielding from stray light, reduced squinting, and easier centering of my eye contributed to the improvement.' ED-E Eyecup installed on the EOS Elan 7E • The ED-E Eyecup helps reduce glare and greatly increases ECF reliability for me..." I've misplaced the URL, otherwise I would have given it rather than quoting as much from his article. Can you, Jon, help me understand how I insert the new eye piece? Thanking you in advance.

Andy		In order to install the new eyecup, you have to remove the old one from the camera. To remove the old one, squeeze on both side of the eyecup and slide upward. To install the new one, just slide the eyecup down the viewfinder. Hope this helps. To love this comment, log in above January 21, 2005

Jon Close		Ditto what Andy S. wrote. Prof. Frary has compiled a very helpful Canon EOS resource at http://emedia.leeward.hawaii.edu/frary/photo_index.htm. To love this comment, log in above January 21, 2005
