Einst_Stein Posted July 16, 2014 Share #1 Posted July 16, 2014 Advertisement (gone after registration) Not every lens I have has 6-bit coding. It's very annoying to switch between manual and auto mode for lens selection. Why Leica cannot make the Auto the default mode, and only go to manual mode if the lens has no 6-bit coding? Better yet, give it a beep reminder when a non-coded lens is attached? It will be extremely welcome through a firmware update. Quote Link to post Share on other sites More sharing options...

mjh Posted July 16, 2014 Share #2 Posted July 16, 2014 With some lenses the camera thinks it is coded when in reality it is not. Detecting whether a lens is coded doesn’t work as reliably as your idea required. Quote Link to post Share on other sites More sharing options...
bocaburger Posted July 16, 2014 Share #3 Posted July 16, 2014 I assume by "auto" you mean "lens detection-ON" and that the issue is you wanting EXIF info for all lenses? Because ever since the M8 I have left these cameras permanently in lens detection-ON although only my lenses 35mm and wider are coded, and have never noticed any unwanted corrections applied to the uncoded lenses. I'm just grateful Leica didn't set them up to display a "No Lens Detected" warning and lockout when using uncoded lenses with detection ON. Michael you are correct, but a dab of flat white model airplane paint on the offending screw head solves that issue neatly. Quote Link to post Share on other sites More sharing options...

Detecting whether a lens is coded doesn’t work as reliably as your idea required. You mean if I left it at auto lens detection, M may treat some uncoded lens to be the wrong lens? Could you name any lens? All my lenses, including old Leica M and Zeiss ZM, show "unknown" if M is set to auto lens detect. Maybe default to auto is not necessary. All I need is to get a beep ( and a flashy screen, saying blah blah blah) when an unrecognizable lens is attached while it is set to auto mode, Quote Link to post Share on other sites More sharing options...
bocaburger Posted July 19, 2014 Share #5 Posted July 19, 2014 There are a very few lenses from the late 70s-early 80s where one of the screws attaching the rear flange happens to reside over the code reader, and it thinks it's a black code pit. One of them is the 90mm (thin T-E) but that one really isn't a problem as the code reader thinks it is a 90! My "tabbed" 50 is one which has that screw, as does my pre-ASPH 21mm Elmarit. As I said, a little flat white paint on the screw head "blinds" the code reader to it, and it registers as uncoded. Or in the case of my 21, as a 21 because I DIY coded it. And Idk why you would need a beep. Unless you carry a slew of lenses with you, I would think you would recognize the uncoded ones. And then there's always the option of looking at the flange as you mount the lens...if there are no coding pits, it's uncoded. Quote Link to post Share on other sites More sharing options...
