well bottom feeder luck again
i picked a VERY clean Practica Super TL1000 (complete with original PX13 Batterie..albeit a little leaky....

) with a Yashinon DS 50/1.7 lens Aus$18.00...
did some research on the lens (i had a vague thought it may be a radioactive lens..yellow colouring and all..)
there is not a lot of info on the DS 50/1.7 but i did find this little snippet...
'Yashinon-DS 50mm 1:1.7 762nSv/h ' (
http://yashica.org/254-2-Lens-radioactivity-measurements.html)
not a hell of a lot but it was one of the higher dosed lenses...
now...does anyone know anything more about this lens? i have not come across this lens before it would appear to be a little on the rare side plenty of dx lenses but very few mentions on the interwebs about the DS lens.
