mikel r. Posted October 11, 2005 Share Posted October 11, 2005 I just purchased a Nettar 515 from the big E-bay after it was recommended by a friend. The shutter was sticking so I proceeded to tear it apart and clean the oil from the shutters. They are still a bit slugish. I think I replaced the rear lens backwards as the edges of the photo are out of focus. It features a Pronto shutter with the Novar Anistigmat lens. The question is, could the corners be a result of the rear element being installed wrong? I love the ergonomics of the camera and the size. It will fit in my pocket easily. My only complaint (once the focus issue is corrected, is that I would like a shutter speed higher than 200 which would allow me to use a wider variety of films. The camera is way better built than my Ansco Vicking and I really like the square format. Following are a couple of photos taken with the camera which, when I do my part, are sharp in the centers. Once I get the problems solved, I will post new photos taken with this camera.<div></div> Link to comment Share on other sites More sharing options...

winfried_buechsenschuetz1 Posted October 11, 2005 Share Posted October 11, 2005 The rear lens element is mounted with the stronger curvature outwards, i.e. there should be a distinct convex curvature visible from behind. The inner surface is almost flat. The center lens element's curvatures cannot easily be determined. If the center lens element is mounted the wrong way round pictures will be totally blurry, you can easily see this on a groundglass pressed against the film rails.

bueh Posted October 11, 2005 Share Posted October 11, 2005 I agree writh Winfried. Matt took a <b><a href="http://homepage.mac.com/mattdenton/photo/samples/baldix_sample.html" target="_new">picture</a></b> with a 6x6 folder that had the rear element of its three-element lens installed backwards. It looks pretty much like your examples. Link to comment Share on other sites More sharing options...
denis_pleic Posted October 11, 2005 Share Posted October 11, 2005 Mikel, I think the previous contributors are right, as you already suspected - it's probably a lens element installed incorrectly after cleaning. However, I must say that I love the results you got with "incorrect" lens element placement - if it were me, I'd leave it the way it is :) Denis Link to comment Share on other sites More sharing options...
Rob_the_waste Posted October 11, 2005 Share Posted October 11, 2005 I like the way the blurring actually frames the picture of Melanie. I think I'll try it with my Ikonta. Link to comment Share on other sites More sharing options...
Rob_the_waste Posted October 11, 2005 Share Posted October 11, 2005 Mike. You can use a wider variety of film if you throw on a polarizing filter that knocks down the amount of light by a stop or two. I don't know what size of lens you have, but on my Ikonta, I have a 4.5 Dominar with which I can use a 32 mm slip on. Link to comment Share on other sites More sharing options...
Andrew in Austin Posted October 11, 2005 Share Posted October 11, 2005 I'm like Rob. I may try reversing the rear element on one my Apotars. Best Regards - Andrew in Austin, TX Link to comment Share on other sites More sharing options...
mikel r. Posted October 11, 2005 Author Share Posted October 11, 2005 Thank you all for your help. I have thought of leaving the lens that way as I have always wanted the Holga look. I have been looking to buy a Holga so I can join the "Holga Cult" I just can't do that with this camera. It is way too pretty and solidly built. I wouldn't even have to use electrical tape to seal the light leaks like the Holga--where is the fun in that? I really like the Hosta shot and the wood with the soft(really soft) edges and the sharp centers. Thank you all again. Mike Link to comment Share on other sites More sharing options...
jurgen_switalski Posted October 11, 2005 Share Posted October 11, 2005 I don't have this camera but I had the same problem with a 135mm lens for my maymia c330. I read the post at lunch time today and grabed my lens and the rear element group was reversed. I flip them over and the image on the ground glass looked great. After work I loaded up some film and developed the negatives. Sharp edges! I bought this lens in 1981. Someone must have thought that this would make a good portrot lens.
