Im stumped! I am shooting with a D90 and a 80-200 AF-D with a Kenko 1.4 Pro 300 TC. It seems as though shooting the same object, from a tripod, and remote shutter clicker at 200mm, the images are more clear with the TC on than the straight lens. I shot through the range of 2.8 - 14 with the lens, then 4 - 16 with the TC attached. Cropped it by 100%, and took a look. Is this normal? I thought I was suppose to lose image quality with the TC? I can post up all the pics if necessary. Thanks in advance!
