[Leica] lens coding

[john at mcmaster.co.nz (John McMaster)]

If this is the first time you have used those lenses on digital then they 
may need recalibrated, if they do then that is the time to code IMO.

Coded lenses make a difference in DNG as well as JPEG

Have to take Leica's word that it is lossless, the S2 was the first to offer 
that so most likely true ;-)

Greetings,

Just received the M 240. All of my lenses are uncoded, mostly 70's and 80's 
vintage. It's not clear to me if having coded lenses helps me if I'm always 
shooting DNGc. Does coding help with anything other than the camera's JPEG 
engine?

Also, is there any loss of image data using DNGc vs DNG. The manual states 
"no", but is that accurate?

Thanks
