> Some of my lenses are coded, some aren't.  My general sense is that 35mm and shorter lenses need to be coded to avoid cyan drift in the outer regions. But for 50mm and longer, it doesn't matter much unless one cares that the EXIF data contains the correct focal length. I've found that when I'm changing lenses in fast situations, I can't count on always changing the manual lens ID in the menu.

> - Buy lens flanges with coding pits from eBay and install and paint them myself. (beware Chinese quality control?)
> - Using my M coder template and an oil-based industrial marker to code the lenses myself. I've done this before, but it is painstaking, requires some trial and error, and has to be redone periodically.
