One of things that comes out in that 28s article is that the cyan cast is not so different and the vignetting of some lenses is also similar to that of their Leica competitors. Cheers, Sean |

To save a lot of time sending lenses back to Leica couldn't Leica provide a kit to carry out the coding by the owners of lenses? The kit would comprise of a template to lock into position on the lens flange and suitable markers to create the code. I do not think that this would be expensive and it would be another way for Leica to support their loyal customers.
My first posting in this forum. Best wishes to all. Barmul. |

This all looks like fun much on the level of making a pin hole camera with an Oatmeal box but if Leica wanted to do the right thing they would put this all in a firmware menu.
Why don't we rather than going out buying sharpies, take up collection and buy a Nikon D200 and send it to Solms. Maybe they could be inspired by the example.

In the meantime, here's a quick-and-dirty template. Print it out; the gray surround should be exactly 2 inches by 2 inches.Cut out all the white parts. The cutout at lower left aligns with the little recessed slot in the lensmount; the holes then represent the code bit positions. It's easiest to get on if you cut the recessed-slot piece all the way through to the edge of the paper so you can just open the template up and slip it on. I've made it a nice shade of magenta :-) If you want a template you can use over and over again, I'd suggest a trip down to Office Depot to get some overhead transparencies to print the template on. That way your sharpie won't damage the template.

Jean,
After rethinking the issue, I agree with you that it isn't eliminating all vignetting, it's only eliminating the vignetting it introduces. So my point is sort of mute. I still think we should be the ones in control of how much correction is applied to our raw data (beyond the typical data formating of course). _mike |

I just looked at an original Leica adapter and it too had the cutout in the coding area. I suppose you could screw the adapter on to the lens and then try the coding on the screw mount flange of the lens itself. You could even just put a piece of white tape on the lens and mark the coding on that. It is only a bit over a mm between the M flange and the exposed screw flange underneath. The coding may still work from that distance and if it does, it is less likely to wear off. Last edited by robsteve : 11/29/06 at 09:20 PM. |

![]() Also, no matter Leica does it with current 6-bit coding on the mount or, through adding firmware functions letting users input the lens data manually - such as Nikon is already doing with the F6, D2 and D200, ... I can hardly believe that Leica will include the optical characteristics mapping of other lenses from Zeiss, CV or whoever else - so as Andy says, all you get is the EXIF data ... who is in desperate need of that - certainly not me. |

an interesting lens to hack would be the CV15, if a workaround for the missing metal can be found.
i looked at the new 16-21 tri-elmar at photokina: reading counter-clockwise at the lens base: w w w w B w. this would be a good shot fot the CV15 |
