Hey all. Been watching Nikon Rumors like a hawk for the past month hoping to see some kind of announcement of the rumored d4x. But lately I have been dipping a bit into the forums and today I thought maybe the experts could give me a bit of advice and help get me off this fence I'm sitting on.
I'm a sports photographer for a number of small town newspapers, its more of a hobby and not my full time job. Over the years I have slowly built up my collection of photo gear and I'm currently carrying a d7000, 70-200mm 2.8 VRII, and 24-70mm 2.8G ED. I'm working almost entirely in low/poorly/oddly lit gyms aside from a few football games and none of the indoors allow flash photography. The following link has a few of my better photos (unedited with EXIF data but in JPEG format) from the previous school year: http://www.flickr.com/photos/62282623@N07/
I have been seriously considering an upgrade to the d4 because all of the wonderful things I hear about its low-light and action prowess. I guess I'm trying to get a feel for how much more the d4 could do in place of my d7000. Currently, I'm probably standing at around 30-40% of shots getting tossed thanks to poor focus and then maybe 10-20% of the remainder having 'perfect' focus. My d7000's AF seems to have problems tracking subjects during bursts as well. I'll rarely push the camera above 3200 ISO, preferring a step or two lower which keeps me around 1/250 in the shutter speed.
Thanks to anyone that can impart any worldly advice.
