Observing the shutter speed of >3200 at ISO 1600, I don't think the problem 
could be camera shake.  I'm sure that the glass will diminish the detail to 
some degree, but I wonder if part of it is noise.  Did you try ISO 400?  You 
should still have a shutter speed of around 800, and, perhaps, better
