andrewtansj Posted March 18, 2010 Share #1 Posted March 18, 2010 Advertisement (gone after registration) Hi all, just gotten a m8 and a 35mm summicron pre-asph. I did a DIY lens coding and the EXIF shows the lens focal length information, but it doesn't show the f/stop info. is this normal? or did i missed out something?

PasMichiel Posted March 18, 2010 Share #2 Posted March 18, 2010 That's true. If you look at all the contacts from the lens to the body it's not connected. In the body there is a wheel: it's for sharpening. There is a strip of red dots: it's for the lens type. And if you look in the finder you don't see any number. Just an arrow. Only the R, X and S has this indication. Link to post Share on other sites More sharing options...
andybarton Posted March 18, 2010 Share #3 Posted March 18, 2010 The camera will estimate the f stop, but there is no way of the body knowing for certain what it is. As MichIel says, the only connections are the bayonet itself, the focussing cam with moves the lever with the wheel (so that you can focus in the viewfinder) and the code which tells an M8 or 9 which lens us mounted without a fundamental redesign of the whole lens and body mount, there is no way to get a lens to communicate the aperture to the body. If this were to be done, then many here and elsewhere would argue that the camera would no longer be a Leica M, but something else. Link to post Share on other sites More sharing options...
