I actually enjoyed the aircraft and hydroplane pics. Well done DPR. AF tracking looks good.
SunnyFlorida: Simply Awesome! an OMD-5 with this lens will be a sweet combo
Kind of reminds me of the 50mm Pentax Super Takumar I bought used recently for $40.00.
As long as the camera woks with my Canon 70-300L...it's the camera of the year.
