I went on a little walkabout today in a park down the road, ended up with a few shots of mostly small birds with the KP, DA*300
and DA 1.4 converter. All cropped.
Without the converter I may not have even tried some of these. They are not that detailed, but without the converter I definitely would not have got the details that I did because of the distance.
Edit: This morning I realized that I did not have the converter on my lens, so these photos were taken without it. We recently took a trip to Ohio and Tennessee and I took the other camera and put the converter on the 55-300PLM. We brought my mother in law back with us, and my wife's brother and his wife came a few days later and took the mother in law home when they left. In the meantime the camera gear was stowed in a different spot and I forgot I had done that. Those photos turned out OK, but I kick myself because they could have been closer. Live and learn.
