Arthur Sanchez Share Posted October 18, 2017 I've been busy experimenting with optics lately and have come across a method to get a little more than 10X viewer form a 6X viewer. This what is what I go... Quote Link to post Share on other sites
Jean-Louis Seguin Share Posted October 18, 2017 Very interesting. I tried this a few years ago and wasn't succesful. There's only so much light coming through and making the frame larger also made it darker. Quote Link to post Share on other sites
Arthur Sanchez Author Share Posted October 19, 2017 Jean-Louis... So do you think it's working? Do you think this looks darker??? Quote Link to post Share on other sites
Jean-Louis Seguin Share Posted October 19, 2017 From the picture, it doesn't appear darker but there is some pincushion distortion. Quote Link to post Share on other sites
Arthur Sanchez Author Share Posted October 19, 2017 Yes I did see that... when you see thru with a lens at a scene it's not apparent at all... it's is very slight, however it is there... Quote Link to post Share on other sites

This what is what I go... Hi Arthur -- I've seen your work and posts before in the Film Camera Repair Directory too, wonderful stuff! Can you share the details on how you worked this magic? I'm assuming you added a diopter into the finder? I'd bookmarked at least one other person trying something like this from Jan-Eric Nyström's now-defunct page on hand-modifying Bolexes to Super 16. He hot glues a small lens in place inside: https://web.archive.org/web/20120123185702/http://www.sci.fi/~animato/s16/s16.html I have to CLA a bunch of ancient Bolexes over this summer before our students use them in the Fall, and a lot of the ones we have are equipped with rather ancient finders (especially the non-reflex ones...) that could really benefit from some more magnification. The other idea I've been playing with is just to attach a cheap viewfinder magnifier -- less than $5 apiece straight from China, and with an eyecup attached to boot! Though the one at the link below may be way too much magnification (2.8x): https://www.ebay.com/itm/2-8X-3-V1-LCD-Viewfinder-Eyecup-Magnifier-Extender-Hood-for-Canon-5D-II-7D/293071188759 Quote Link to post Share on other sites

Arthur Sanchez Author Share Posted March 9, 2020 Hello Thomas, Optics... I've come to the conclusion the it's simple VooDoo black magic... An understanding of the principles of light is essential. I've found that it is a well kept secret, as I've yet to find a person that can do my optics. This is an early Ver. 1 of this attempt. Do you do Optics? Quote Link to post Share on other sites
Arthur Sanchez Author Share Posted March 17, 2020 Hello David and Thomas... Please contact me direct through my website: drbolex.com Lets see where we can get with optics. Arthur! Quote Link to post Share on other sites
