portocar Posted April 13, 2007 Share #1 Posted April 13, 2007 Advertisement (gone after registration) I've got a Contax Carl Zeiss Hologon 16mm f/8 lens waiting to be converted from Contax G mount to Leica M mount. The technician is going to use an actual Leica M lens mount to replace the one on the Hologon 16mm lens. All I need to know is, what framelines do I want the Hologon to activate. The technician says he has either a 28mm or 90mm leica ring/mount available. From what I have read on this forum, so far, it seems that the WATE activates the 28/90mm framelines. So, I am guessing that either the 28mm or 90mm ring/mount would be fine to install on the hologon. Please advise. Link to post Share on other sites More sharing options...

rwfreund Posted April 13, 2007 Share #2 Posted April 13, 2007 I don't think that it matters much, since none of the above is the correct answer. 16mm will result in a wider angle than the viewfinder provides. You might be looking for a 21mm accessory viewfinder to see what you might get. -bob Link to post Share on other sites More sharing options...
marknorton Posted April 13, 2007 Share #3 Posted April 13, 2007 The 28 and 90mm frames are activated by the same mount... but of course you would normally expect to use a finder. Link to post Share on other sites More sharing options...
sean_reid Posted April 13, 2007 Share #4 Posted April 13, 2007 If you're planning to hand code the lens then, yes, a 28/90 mount would be the way to go. Cheers, Link to post Share on other sites More sharing options...
portocar Posted April 13, 2007 Author Share #5 Posted April 13, 2007 I don't think I was clear enough. I am not interested in the framelines to use for actual framing. It turns out that the Leica M8 not only uses the 6-bit code for image optimization, it also takes the framelines into account. I plan to code the Hologon, but I also have to get the framelines right, for the M8 to apply its image optimization. So, can a WATE owner please tell me what framelines are activated by the WATE? Finally, if it turns out that the framelines are 28/90 mm, does it matter what ring/mount I install on the Hologon: 28mm or 90mm? Link to post Share on other sites More sharing options...
robsteve Posted April 13, 2007 Share #6 Posted April 13, 2007 Nestor: The wate brings up the 90mm/28mm frameline pair. This was answered at least four times in the last thread you asked it. Link to post Share on other sites More sharing options...
