Have they ironed out all the issues with the stained sensors?
I believe they have for the most part, I have checked mine and ran video to heat the sensor and have found nothing on mine yet. I think you are safe unless you get an older one. The only other issue has been a rare scenario where you get FF under tungsten light at a few EV steps and even then it seems to only affect some and only in a situation you basically have to force yourself into. The FF issue appears to be affecting the nikons 7000's and some canons as well though.
I was most impressed with the shot there because usually you wash a lot shooting the sun and especially the ground and in this case it is nearly looking like an HDR shot......
