I was out at our neighborhood park and happened to see a plover hanging about a construction ditch across a fence. It was sunny and seemed to be a good opportunity to put my 200 f/4 Q.C through its paces. The bird must have been all of 30 feet away. I mounted the 200 f/4 on my modified TC-16A (to make a 320 f/6.4) and proceeded to take about 10 shots, figuring I would get at least a couple of keepers. Well, when I reviewed the pics during PP, I was disappointed to find that the sharpness after cropping was just not up to the mark. Wondering if this is par for the course for a ~300mm lens shooting ~30 feet out, or rather a limitation of my setup? I have been able to get sharp pics with this setup in the past of a gull that was perhaps 10 feet away, so I preliminarily assumed that it was viable for bird photos.
I'll add samples to this post as soon as I get a chance.
