Coots and Mallards
Note the sharp focus on the coot behind the spray. I'm both pleased and annoyed.
These were shot at f/4.5 or f/5.6 (eff. f/9-f/11 with the teleconverter). I'm trying to see if I can avoid pushing the ISO and shutter speed as hard when shooting with the teleconverter on, but still be able to recover some sharpness in post-processing. As you can see, the results are partially, but not entirely succesful.
