Thanks Richard, The scratch was there when I got the camera off ebay - but i did not pay more then 100 usd for it and asa long as she uses the hood/shade it does not show on pictures ! I will leave it as it is untill I find a set of matched view/take lens from a junked camera. I know there is a lot of tessar/XENAR and Planar/Xenotar talk on these list but so far I have not been able to see the difference between the tessar and the Xenar - I took the same picture with both on the same fil and ames setting and scanned them at 4000 dpi and they looked very much alike - lovely both of them actually I am getting more and more happy with my own tessar on the automat ! I t gives my Leicas a hard run to the motifs! I got another automat the 1956-7 with the coupling of EV values - the first model - it has a tessar to but not the word "opton" as my 1951-1953 automat - are they the same lenses anyway ? all the best Ruben ----- Original Message ----- From: "Richard Knoppow" <dickburk@xxxxxxxxxxxxx> To: <rollei_list@xxxxxxxxxxxxx> Sent: Tuesday, April 12, 2005 7:17 AM Subject: [rollei_list] Re: recoating and polishing the Xenotar lens > > > -----Original Message----- > From: Ruben <ruben@xxxxxxxxx> > Sent: Apr 11, 2005 9:28 PM > To: rollei_list@xxxxxxxxxxxxx > Subject: [rollei_list] Re: recoating and polishing the Xenotar lens > > On another list - range finder forum - also a nice place - one member sent > his front element off his Summicron to ARAX in the Ukraine and had it > pulished and coated for 30 USD ! he was vey happy with the result.
