First of all: Happy new year for everybody! Now, I have two questions I would like to ask: - I am about to buy a second hand Nikkor AF 20mm f2.8 from a friend of mine. It seems to be in excelent condition, but I just found out that he normaly uses lens cleaning paper to clean the rear lens element - without any cleaning fluid (or alchool)!! Is there any chance the glass might be damaged? Isn't the paper a bit to abrasive for the lens coating? I am not worried about the front element because he allways uses a UV filter and never had to clean the lens glass itself. - I bought a MF 26 back for my F90X 4 months ago and it seamed to be working fine. Last week I did some shooting in cold weather (about 0 degrees Celcius - snowing) and it kept on reseting - the date went back to 1/1/92 and all my settings disapeared. This happened each time it stood outside for some time. Is this normal behaviour or should I that it to be serviced? Thanks, Tiago Fonseca
