The funky bokeh looks like it is due to the floating element (CRC) similar (but a little stronger amount) to my minolta 28 f2 which has a floating element.
Bokeh maybe a bit busy but your girlfriend in her bikini is easy on the eyes! :P
Makten, thanks for posting your samples form the Vivitar/Polar/Samyang/Whateverelseitgoesby 85mm f1.4. Picked one up from B&H a few days ago, love it, especially for $350. Not the best sample for bokeh but I'll be sure to post more when I get better examples.
I'd probably reshoot @ 5.6, ISO 100, tripod / MLU & use 2.5x angle finder for focus, for better technique ... but I was just 'exploring' mfd on the 24mm
Incidently, it was my Bday this weekend, and my buddy as a bit of a present, has lent me his Zeiss Sonnar 135 2.8. I've only taken a test shot with it so far, but holy wow. It made my box of saran-wrap look amazing!
Can't wait to play with this lens.
For what it's worth, thanks for posting that original pic... If it weren't for that, my interest in trying a 135 would have never materialized.
