A better solution is to use isopropyl alcohol....but even then the engraving remains

L1002601-Edit by woodswoman57, on FlickrThank you zleica for your images. This thread seemed to have died before you posted them. I hope others will get this interesting lens and post more images. I have been using my prototype as my go-to lens right now with the M10M, especially for portraits like this one.

Few comments from my very early and limited observations: 1) material is really excellent with very good color renditions; 2) The Quality assurance statement from the street vendor seem to be pretty consistent with the copy that I got; 3) mechanically, the hardware is very well made with smooth feel (not too light) and positive button clicks; 4) overall, my copy is without any defect and misalignment. Although I have not made any comparisons with other real LV or Humus bags that I have, from about 100+ days using, these bags do have some unique and interesting characters, particularly view from 1 - 3 meters distance is very attractive. In some way, these bags are good for shopping in farmer market ………….

Both the ELCAN and the Elmar (along with the Zeiss Tessar) are triplet derivatives. They share some image qualities of sharpness and clarity at the center, and a roundness of image which is very pleasing. Only the others 2 lenses are f/3.5, and stretched to f/2.8, not f/2 like the ELCAN.
