Excuse me for the poor english of a frensh user.
Can u explain me how you can get this picture at 392.0mm f/6.3 seting with a 70-200 f/4L IS USM Lens ?
The only way to get a 392mm is to use a TCx2 (teleconverter) or with this combination the max aperture seting (20-200 f/4 with TCx2) is f/8 (2 f-stops loss with TCx2, one with TCx1.4).
So there is a dilem for me, so whatever the lens used is not the a f/4 lens one or the 392.0mm is wrong ?
