jaapv Posted May 10, 2011 Share #2 Â Posted May 10, 2011 The Brightscreen is not recommended. It has a hotspot. Link to post Share on other sites More sharing options...

spydrxx Posted May 11, 2011 Share #4 Â Posted May 11, 2011 Years ago I tried one of Bill Maxwell's screens, but it too had a bright spot, with severe vignetting at the perimeter...totally useless for me. I recently installed an old Nikon screen with a split image RF patch and microprism surround, the test shots for alignment haven't yet been developed, but with minimal shimming, it seemed to be spot on in focus with a ground glass in the film plane.

Cheers.   Hi Washington,  Here is an image that I took with the M9 + Viso III + Telyt 400/5.6 after John Van Stelten of Focal Point Inc. in Superior, Co - just down the road from you - cleaned and adjusted the Visoflex. I find the view through the Viso Viewfinder now very bright and clear. As my eyes are not the best, it's always a hit and miss, but I get more keepers than I get with automatic focus on my D3. I prefer "better lucky than smart" any day.  Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! You probably notice the moire pattern in some of the fine feathers of this Curve-Billed Thrasher. I consider that confirmation that focus was dead on. Please correct me if I am wrong.  You have been very successful working on your Visos and trying out stuff. Some time ago I bought a few RICOH KR-5 KR-10 FRESNEL LENS 3119-6227 screens for use in my Visos. But I changed my mind. If you want to try out this screen in your Viso, please send me a PM with your contact info, and I will mail one of the screens to you to keep. I am still curious to find out whether that screen would be an improvement over the original tried and proven Leitz real glass screen.  Best, K-H.

Washington Posted May 11, 2011 Author Share #6  Posted May 11, 2011 K-H, Thank you for your kind offer which I will take you up on! As soon as a wake up enough I will drop you a line. Truth be told, when all cleaned up, I have no trouble at all with the very nice real glass screen. So, no doubt, I am looking for trouble where there isn’t anyway ….. but I was just curious. I somehow had the impression that a screen with a split-image center didn’t work with long lenses as on side of the split blacks out. Do I remember correctly? Again, they take no time at all to change and I was just wondering. Thanks for all the info. Hey, who is that Leica guy near me???? Cheers. Link to post Share on other sites More sharing options...
Washington Posted May 11, 2011 Author Share #7  Posted May 11, 2011 Advertisement (gone after registration) Oh, I see that Superior is just past Boulder on #36. I’m down that way quite a bit as I have to drive that way to get to the Denver VA hospital. Thanks. Link to post Share on other sites More sharing options...
tobey bilek Posted May 12, 2011 Share #8 Â Posted May 12, 2011 It already has the most perfect screen for the range of lenses used on the viso. Â The replacement or alternative screens for slr cameras that are supposed to be used for tele lenses are of similar design, none as good, but similar. Â To get better, they are made for very specific focal lengths and apertures. Then you are forced into changing them to suit the occasion/lens at hand.

Washington Posted May 16, 2011 Author Share #9  Posted May 16, 2011 This was pure curiosity on my part. I’m just messing with it for my own view. But, my gut feeling is that you are quite right! Cheers. Link to post Share on other sites More sharing options...

Washington Posted May 16, 2011 Author Share #11  Posted May 16, 2011 Yes, I have the screen you were kind enough to send me. Just a tiny amount of sanding on length sides and it fit the frame just fine. It needed a .031’’ frame shim to fit tightly as it was this much thinner than the original glass. The very thin smear of silicone sealer holding this very delicate shim in place is setting up now and I will be reassembling it a bit later today. I will let you know for sure. By the way…. what camera did this come from again????? Link to post Share on other sites More sharing options...

Washington Posted May 16, 2011 Author Share #13  Posted May 16, 2011 Thanks K-H, I ask because if this proves interesting… I would try to find a matt screen of the same size. As I told you, I seem to remember problems with split prism screens on long lenses…. one side of the central split blacking out. But, that may turn out not to be the case….. we shall see soon!

k-hawinkler Posted May 16, 2011 Share #14 Â Posted May 16, 2011 Washington, Â It may well be so. I just don't have any experience and simply don't know. That's why I really appreciate you figuring it out. Many thanks. Â Best, K-H. Link to post Share on other sites More sharing options...
Washington Posted May 16, 2011 Author Share #15 Â Posted May 16, 2011 Well, one plus: the screen is inexpensive enough to play with. Link to post Share on other sites More sharing options...
Washington Posted May 16, 2011 Author Share #16  Posted May 16, 2011 K-H: Quickie Tests. I used the 65mm Elmar for these. Using the split image center. It is another grey dark day…. I would like more light & contrast. These are 100% enlarged sections with no processing or adjustment at all. Interesting! I tried a 135 but began to have trouble with blacked out central split-prism. However, as this is a f-2.8 lens, wide open (where you focus anyway) cleared the black central split spot! I do have some thoughts on this subject - but I will wait until I take more photos. Cheers!!!! Welcome, dear visitor!

Washington Posted May 17, 2011 Author Share #17  Posted May 17, 2011 Oh, these pictures were taken only to test the focusing accuracy of the split image center of the new screen…. so they are just things with an edge to focus on….. they are not meant to be good pictures.

k-hawinkler Posted May 17, 2011 Share #18 Â Posted May 17, 2011 Hi Washington, Â Could you make an image like the second one in here: http://www.l-camera-forum.com/leica-forum/1314029-post4.html? It would show how the screen performs. Â Best, K-H. Link to post Share on other sites More sharing options...
Washington Posted May 18, 2011 Author Share #19  Posted May 18, 2011 Yeah, that’s interesting. Pardon my vanity, but the the only shim material I found to be used at the top of the screen/frame interface was a rubber sheet bought for making new strips to replace degrading textured rubber bands on a few lenses. But, it worked just fine as a shim. However, the inside edge is a little jagged and slightly protrudes into the viewing area. At this point I was not being fussy as I just wanted to see if it worked. So, I simply have to trim it clean before I display it as you suggest… again, neatness & vanity. I still think a precision matt screen is the best bet for over-all use. And damned if I didn’t have one right here. I never thought to check these for size and adaptability… it’s for my Cannon Mk III Ds. This is a thicker screen than the one you sent me and will require a .019 thickness shim. I’ll find something as I think this screen would be ducky. All in all, this is proving quite interesting!!! Give me a little bit and I will provide the photos as you suggest. Link to post Share on other sites More sharing options...
Washington Posted May 18, 2011 Author Share #20  Posted May 18, 2011 K-H, Not exactly what you asked for but I just wanted to see how it looked this way. I see a couple of hairs on the screen bottom to blow/vacuum out. Welcome, dear visitor!
