Hello my name is Reese and I shoot elite level Olympic type sports using Pentax pro gear, most of the events being at the world cup level. I have never encountered another Pentax shooter using pro gear but trust me, the K7
with FA* lenses (I don't have any DA* lenses yet) produce as good or better
images to those of Nikon or Canon gear. The color transmission of the SMC glass is fantastic and for that reason I am sticking with Pentax. Examples of my work, including a world record being set in swimming, can be found on Flickr:

Now lets keep our collective fingers crossed for a full frame DSLR by 2012!!
