Wife tried shooting XTi with 70-200 IS2 + 1.4 TC3 through glass pane for birds at feeders. The focus confirms, but results are horrible. I put the lens setup on my 5D3 and get the same horrible results.
When shooting the same distance without glass pane in the path, focus is dead on for both cameras. The glass pane is squeaky clean.
Any ideas? I'd guess trying a polarizer but I don't have one the correct size...
