Coded rings are adapter rings produced by John Milich for LTM lenses, 
ie, the CV LTM lenses.

You can shoot with your 21 and filter, and after you get back get 
Cornerfix, produce the adjustment images, and then correct the images 
you have shot. It's quite simple and quick and will give you better 
results than not using a filter. Cornerfix allows you to batch 
correct, and it will correct whatever it finds, so leave 'IR/UV lens 
detection' on, and then select the images by whatever EXIF data is 
produced for your incorrect lens mount, and then batch correct those 
lenses with the correction profile produced by the same lens with the 
same camera settings when you get back. It sounds a lot more 
complicated than it is.
