arlindo_barlera Posted June 16, 2015 Share Posted June 16, 2015 <p>Super Heliar 15mm and 72mm filters? Yes!<br> Since I consider the only industry made filter holder available for the Voigtlander Super Heliar 15mm so much expensive for me, and requires 77mm filters, I wondered if I couldn’t make one myself. With a bit of ability and a lot of patience and after a lot of mistakes and lost services I finally achieved the result shown in the illustration. It allows me to work with my 72mm thread filters, absolutely free of vignettes. The mine is specific for use with a Canon vT camera, but a similar device can easily be made for any others camera. I tested the holder with a roll of b&w with an excellent result; no one crop at the corners. This holder obviously don’t touch the lens barrel and allows free access to the rings of exposure and f.stop settings, but the lens cap only can be accessed without filters. The holder don’t need to be removed for change of roll film.<br> </p> <p> </p><div></div> Link to comment Share on other sites More sharing options...
james_elwing Posted June 16, 2015 Share Posted June 16, 2015 <p>Not sure I know what is happening here. Is the lens cap on this side of the filter?</p> Link to comment Share on other sites More sharing options...
arlindo_barlera Posted June 17, 2015 Author Share Posted June 17, 2015 <p>No! What you see is the camera with the lens cap and the holder, but without filter. It's necessary to remove the lens cap to thread the filters in the holder, because the distance between the front barrel of the lens and the filter is shorter than the lens cap width. You can see other ilustrations at my portfolio.<br> Regards!</p> Link to comment Share on other sites More sharing options...
mukul_dube Posted June 17, 2015 Share Posted June 17, 2015 <p>A large diameter filter and no hood is asking for trouble, I think.</p> Link to comment Share on other sites More sharing options...
arlindo_barlera Posted June 17, 2015 Author Share Posted June 17, 2015 <p>I apologize for my poor English! What I'd want to see is that "<em>the space between the front barrel of the lens and the filter is shorter than the lens cap <strong>tickness.</strong></em></p> Link to comment Share on other sites More sharing options...

aplumpton Posted June 17, 2015 Share Posted June 17, 2015 <p>With the filter separated from the lens by the intervening lens shade the question is (1) how is the holder held and (2) does the distance degrade the on film image when the filter may unavoidably carries on its surface a bit of dust or other particles? </p> Link to comment Share on other sites More sharing options...
james_elwing Posted June 18, 2015 Share Posted June 18, 2015 <p>I don't think most lens hoods do a lot of work once the focal length gets this wide. This 15 looks like the earlier TM lens with permanently fixed hood. Yes I suppose dust on the exposed filter could reduce contrast. I assume the filter holder is screwed into the tripod bush; big but effective. You could try to keep an eye out for a centre graduated ND filter to cut down on light fall-off at corners and edges. They make them for larger format cameras. Neat job.</p> Link to comment Share on other sites More sharing options...
knut_schwinzer Posted June 18, 2015 Share Posted June 18, 2015 <p>Neat, Arlindo! And I don't speak of the red satin!<br> I assume it crops a good piece of the view through the finder, like many hoods in the RF world.</p> Link to comment Share on other sites More sharing options...
