bnelsch Posted December 4, 2006 Share #1 Posted December 4, 2006 Advertisement (gone after registration) I was at the Leica Days at S&S Optik in Englewood Colorado this past Saturday trying out the 28-35-50 TE on my M8. The lens was uncoded. Even so, the EXIF data shows the correct focal length as you can see from these screenshots: What gives? Link to post Share on other sites More sharing options...
Advertisement Posted December 4, 2006 Posted December 4, 2006 Hi bnelsch, Take a look here EXIF data on TE without coding. I'm sure you'll find what you were looking for!
mike prevette Posted December 4, 2006 Share #2 Posted December 4, 2006 f18.9 ?????????????? I knew those TE's were slow, but thats crazy _mike Link to post Share on other sites More sharing options...
stunsworth Posted December 4, 2006 Share #3 Posted December 4, 2006 Bill it appears that the original Tri-Elmar on an M8 uses the frame selector to determine which focal length is selected - this has been mentioned by people using the coded version. Not sure if this works with standard 20-50 lenses. Can't see why it couldn't Link to post Share on other sites More sharing options...
thisaccountisdeleted Posted December 4, 2006 Share #4 Posted December 4, 2006 I was at the Leica Days at S&S Optik in Englewood Colorado this past Saturday trying out the 28-35-50 TE on my M8. The lens was uncoded. Even so, the EXIF data shows the correct focal length as you can see from these screenshots: what firmware version is the camera running? do you recall what aperture you shot at? i hope the f18.9 is an indication that newer firmware estimates the aperture with help from the blue dot. as for recording the focal length.. if it's uncoded i can only imagine that it guessed based on the position of the frameline lever.

bnelsch Posted December 4, 2006 Author Share #5 Posted December 4, 2006 I have firmware version 1.06. I should have used the screenshots from the C1 which has all of the correct EFIF data. Something gets lost in the translation from C1 jpegs which are then read in Picasa. Note that the max focal length is f/4. Since the focal length is taken from the cam and not the coding, and since the only apeture for that lens is f/4 then coding isn't necessary for the TE. Right?

ho_co Posted December 4, 2006 Share #6 Posted December 4, 2006 Bill--very fascinating. Implication would be that if you held the frame preview lever to a position other than the one selected, the camera *might* report that focal length. How does the camera figure out it's seeing a 50mm and not a 75mm, or a 24mm and not a 35mm, for example? Anybody got uncoded lenses to play with? We'll soon be able to build an M8 emulator in software... --HC Link to post Share on other sites More sharing options...
