[whereswayne]

i am thinking of buying it and am wondering if it is all its cracked up to
be?
or is saving up for the 85mm better bet
i am looking for a portrait come landscape lens come people even a macro
lens with pentaxes marvelous convertor the heliocoid windout thing
i currently use the vivitar 35-85mm for such work and am reasonably happy
