This is from the Nov 12, 2011 game of Michigan St vs Iowa. Nikon D300 Tamron 70-200 2.8 IF 1/2500, ISO 250, f/2.8....white balance on auto. Look at how terrible this photo looks. The bokeh is terrible, the image isn't crisp. The 10 images from this sequence and most others are very similar. I need suggestions on my problem here. Is it because I'm shooting wide open at 2.8 and not getting a crisp image. Is there a chance my sensor or lens needs to be cleaned? The images I used to take with this lens and camera were much better than this....and my D7000 + 300mm f/4 lens performed far superior today... Even the bokeh looks 'shaky' below...not creamy.
