My first impressions of this converter are good, ok the focus is a little slower than before and it's hardly that noticeable plus you still get great bokeh at f5.6, the image quality is far better then my older Sigma 150-500mm lens. So it was worth the money.
So todays test was of birds and birds in flight.....
ALL of the above shots are hand held, I did take my monopod but it was far to difficult to track the moving birds across the sky so I gave up using it.
