I shot a few pics at 1/30th with my 25 and 38 that came out fine. The thing is just so light and well balanced—it really feels steady in the hand at slower speeds. I recently tried a few shots at 1/15th and slower (though for the latter I was using some wall or post support) but I'm still away on xmas vacation and won't have a chance to process everything until I get back home this weekend.
Sometimes I post my photos on flickr
Sometimes I update my tumblr
