EOS Bodies / Will origional 5D & 600ex flash be compatable (read poss only sync @ 100th?)

« on: December 22, 2012, 09:56:31 AM »

As I have 3x origional 5d bodies which work well for my wedding photog buisness, I need to replace a 580ex flash & would like to use the new 600ex, it will be only used on the hotshoe  but I am wondering if 200th flash sync & TTL ext still function as normal. This way when I update to Mk3 ext the flash will be able to be more compatable.

any advise is appreciated. I have looked online but all threads seem to refer to 5dMk2 / 600ex function compatability. Cheers Pete

EOS Bodies / black focus points on 5Dmkiii

« on: December 11, 2012, 08:07:15 PM »

Also are most photographers of the opinion that the focus points on the 5Dmkiii being black when activated is a major difficulty in low light or is it not such a major problem.

EOS Bodies / 5Dmk111 dual cards write speed plus quantum blade opinions.

« on: December 10, 2012, 08:02:34 PM »

I am using 5D bodies at present & am looking at upgrading to the 5Dmk111 to provide a better viewing screen for checking exposures & better quality files with upgraded digi 5 processor ,even though my 3x 5D are working perfectly& I'm very happy with results.
       Understanding that if I want to use a CF & SD card to record Full RAW files simultaneously for back up purposes for wedding photography & that the write speed is governed by the slower write speed of the SD card internal canon connection. Does anyone know the resulting frame rate available? & is it really aproblem if I'm not shooting multiple frames.
       Also I'm considering purchasing a "quantum blade battery" for those bright Australian summer beach shoots which drain AA batteries quickly so the flash keeps fully charged while being used heavily for fill flash. I think I prefer the blade to clip on & cable styles so the camera remains unattached to me . I have heard the blade causes interference on the 5D & I heard rumors some folks have had flash failures/burnout due to the constant power causing overheating ext, any opinions or experiences would be much welcomed B4 I spend any money. Thanks Pete
