NEW M8 Serie

Good point, Rex, about changing the values later.

 

Being able to change coding at will, has an added benefit. For us perpetual tinkerers, we can "improve" on the factory model. This opens the infinite possibilities of arguing incessently about the "proper" coding of a non-leica lens. Think of the fun! :p

You have noted that the VC 28/1.9 if self-coded as a Leica 21/2.0 might overcorrect the cyan shading. If that is true, why can't the enterprising photographer simply code the non-leica lens with whatever leica lens has the appropriate amount of cyan correction? I know it has something to do with the frameline selector but I don't get it.

I assume when self-coding screw mount adapters that "fooling" the camera is 100% successful.

Hi Rex,

 

The 28 Ultron does better coded as a 28 Elmarit Asph. (see the newest revision of the 28s article). In a white wall test, it's still slightly over-corrected in the corners at smaller apertures (because it vignettes less than either of the two Leica lenses) but for many real-world pictures, it isn't very noticeable. In order to trigger lens corrections, the camera relies on both the frame line selector and the code. Both have got to be right.

 

Cheers,

Hmmmm. What would happen if I coded a 24mm adapter with a 35mm/2.0 code? What would the camera think? Does this mean that there are 3 times as many codes possible thru the 6bit arithmetic?

You could code a 24 to trigger a 35 code but then the cyan drift correction would be wong.
