This is the frame before one I sent in a couple of weeks ago and some said not quite sharp enough and Dorian thought the bird should be more central as it did not seem to be going anywhere . I have tried to correct this .In any case even in a 30th of a second the aspect is considerably different..It now become a 50%plus crop and I think the result is pretty good with this lens which seems very good value on this camera anyway.
Love the pose you managed and the gaze at the viewer! Unfortunately it looks to be suffering from IQ and noise, maybe due to the crop, maybe due to ISO. What was your ISO? Did you try using some noise reduction SW?
