Adding to what Joe wrote: the lens codes are read by the M8 and M9 body, and used to apply corner corrections to the RAW/JPG at the time of capture/recording. Each lens should be coded as itself, in the case of a recent Leica lens without code, or the best match in the Leica lineup, in the case of Zeiss and Voigtländer. The best match is not always the most obvious choice, since Leica lenses often have less vignetting, for example, so ask around here or on l-camera-forum.com to get the right code. Then look it up in the table, get the correct pen, maybe a template, and draw it on.
Since the code for the lens is on the lens, each lens only needs to be coded once, and the body will recognize it when the lens is attached. However, the code will tend to rub off, except in the case of the Zeiss and Voigtländer lenses which have a groove where you can draw, and which doesn't touch the camera when you attach the lens. It might be worth spending a bit more to track down such a mount, if available. Lenses coded in grooves should last more or less forever. Leica will code Leica lenses only, and it costs somewhere around 100 Euro, maybe a bit more.
The framelines are brought up by slight differences in the shape of the bayonet mounts on various lenses. On the M8, the possible framelines are: 24, 28, 35, 50, 75, 90. These correspond to the lenses you put on. Due to the 1.33x crop factor of the M8, the angle of view you will see with these framelines, and in the final shot, are approximately: 32, 37, 47, 67, 100, 120. On the M9 the possibilities are: 28, 35, 50, 75, 90, 135, and since it is full frame, this is actually what you get.
For lenses wider than the widest frame supported in the body you get, you will need to use an external viewfinder, usually placed in the hotshoe. Alternatively, the lens one focal length wider than the largest frame can usually be approximated by using the whole viewfinder, i.e. 21 (effectively 28) on the M8, 24 on the M9.
Note that the framelines in the M8 are not the same size as in the M9, due to the crop factor adjustment.
Some Zeiss and Voigtländer lenses used to come with mounts which brought up less useful framelines (I think the ZM25 might originally have been such a lens, bringing up 28 rather than 24, IIRC), but I think that they have meanwhile been changed and new lenses should be correct. I also believe that Zeiss will replace the mount if you prefer another, but I am not sure if this costs more money. The trick is to make sure that you buy a lens which bring up the framelines you want. This is only really an issue buying second-hand....Show more →
Thanks for taking the time to explain. I might go and have a look at a M8/9 before Christmas and have a play with one.
Cheers

The first shot is my favorite.
