: : I have an old Ektar 127mm lens. I noticed that it has

: : It looks like there is no coating. Do I have any
: : options with regard to polishing the outer surface? Is
: : this possible? Also, if I use a larger f-stop,
: : will the scratches interfere with the image quality?
: : Many thanks.

: Some Kodak Ektars were "Lumenized," or given an early
: type of coating. It was rather soft and rubbed
: easily. The scratches you see may be in the coating,
: not the lens. Look at the words around the edge. If you
: see the letter "L" in a circle, you have this early,
: soft coating. I've used an Ektar with a scratched
: coating for years and have never noticed a problem.
: Indeed, the lens is consistently sharper than a newer
: Schneider I have.
You must be wrong
Lumenized means hardcoating. I have the same lens
an Ektar 127mm/4.7 with a L - mark.There is an information
from Kodak that says:
You have a lumenized lens or hardcoated lens
etc. My lens has a production date of 1951.
