More trials with Stacked Converters
Following my trials with the 1.4 and then 2x converter I decided to have a bit of fun by stacking the two to give a focal length of 1120mm (1792 if you inc the crop factor) with my 400mm f5.6 lens. Think results may have been a bit better if I had a remote release but I was still suprised at the IQ. Think what this shows is the quality of the Canon 'L' glass.
