Thanks Jack. Just a feeder pic, which I usually don’t bother to shoot, but it was easy to focus on him here. I’m hoping Pentax will develop some new autofocus full frame converters. I’d prefer a 2X, but a 1.4 would be good as well. BTW, I don’t see anything that I would call noise or grain, even on my 5K Retina display. There is some texture in the out of focus areas, but I think that’s more the result of bokeh than noise.
