lens vignetting can be corrected within the 7D isnt it? unless the new 15-85 lens info havent been added into the 7D.
i presume the 3rd party flash is triggered via the centre pin? maybe blocking the other 4 pin connections on the hotshoe might help? :dunno:
regarding the fps settings on the 7D
if u set ur cam video system to PAL it can only take 24, 25 and 50fps (since these are PAL specifications)
change it to NTSC, and u can take 24, 30 and 60fps. (NTSC standards)
i used the peripheral illumination correction but vignetting is still quite noticeable especially with light/white background
thanks, now i can record using 30 frames
well apart from the above, i love my 7D
