900mm at 1/800 is quite realistic as one can theoretically shoot 50 at 1/50, 135 at 1/125 etc. without "motion blur". The question is rather about _focusing_.... BTW. How is your longest time to shoot 50mm steady? Mine is 1/15 when kneeling and using so-called "sniper breath technique"... -- alkos.atspace.com alkos at tlen pl
