Artichoke Posted June 30, 2007 Share #1 Posted June 30, 2007 Advertisement (gone after registration) I thought I would share this curiosity with the group I stumbled on a second generation 90 Summicron in a local shop & bought it at a very good price it surprised me with its quality, even wide open but even more so I was surprised to learn that my M8 recognized it as a 90 Summicron! it is not coded in anyway of course this has little value other than to identify the lens in the EXIF, but I thought I would share this oddity with the group I don't understand how this happens, but I am not complaining Link to post Share on other sites More sharing options...
Advertisement Posted June 30, 2007 Posted June 30, 2007 Hi Artichoke, Take a look here curious observation from 90 Summicron series II. I'm sure you'll find what you were looking for!
andybarton Posted June 30, 2007 Share #2 Posted June 30, 2007 Presumably, the camera knows it's a 90 by the frameline setting. Link to post Share on other sites More sharing options...
carstenw Posted June 30, 2007 Share #3 Posted June 30, 2007 It could have been an uncoded 28 Cron, no? Is there a screwhole somewhere over the lens code sensor? Link to post Share on other sites More sharing options...
adan Posted June 30, 2007 Share #4 Posted June 30, 2007 The frameline setting alone wouldn't work - the lens could be a 16/18/21, 21, 28, or 90 and "key" the 90/28 frames. Likely either an especially dirt-filled screwhead or scratch in just the right place to appear as a coding dot - or perhaps dust/dirt on the glass cover of the lens sensors. But why question fate? Enjoy! The flip side to this is that I just got one of John Milich's excellent codable screw-to-M adapters for my 15mm C/V and coded it as a WATE - my chrome M8 recognizes it no problem; my black body won't read it at all...(?). The coding was a quick and dirty Wite-Out+Sharpie job, so I'll redo it with real enamel and see if that makes a difference. In any case, the sensors can obviously be fooled, in good or bad ways, by one factor or another. Link to post Share on other sites More sharing options...
farnz Posted June 30, 2007 Share #5 Posted June 30, 2007 Arthur, I have the latest 90 Elmarit uncoded and my M8 recognises it too. Andy, I have the same problem with my Milich adaptor and my M8 (black) and I, too, am waiting for some enamel paint - from a well-known online auction site. So far I've used a CD-R marking pen and a gel ink pen but no dice. Lord, give me patience - right now! Pete. Link to post Share on other sites More sharing options...
Shootist Posted June 30, 2007 Share #6 Posted June 30, 2007 It's because of a mounting screw being in the right place for the 6-bit coding to pick it up. I have a 135 f/2.8 that is also uncoded and seen as a 90mm. Link to post Share on other sites More sharing options...

I just tried, my 90mm Summicron does get recognized but as a 90mm f2.8... well, better than nothing Thanks for sharing this with us! Link to post Share on other sites More sharing options...
Laki Posted July 1, 2007 Share #8 Posted July 1, 2007 thanks for the hint it works for mine as well Link to post Share on other sites More sharing options...
