In Moscow, she will no doubt visit the enormous flea market at Ismailovsky Park. Have her look for 20mm f5.6, 50mm f2 "Jupiter-8", 85mm f2, and 135mm f4. Everyone tells me the 50mm f1.5 "Jupiter-3" is great, but I've never seen one in working order. Give your sister a lesson on how to properly inspect a lens - simple stuff. <<<<<<<<<<< It occurred to me that there could be a relatively simle way of testing some of these erratic quality lenses and avoiding duds like Tom A's 20mm Russar problem. Take along a (Leica) screw mount focussing screen, these were made by a variety of manufacturers, and a magnifying device, a 8-10x lupe would do. Then you can check for correct image and focussing on the groundglass at both infinity and close focusing distance. I had a 35/2.8 lens once that was hopelessly out, nothing could be made to come into focus, though extenally it looked pristine... Caveat Emptor. Always a little trickier for a rangefinder camera buyer though! Jem
