EOS Bodies / Re: 6D vs 5Diii vs 5Dii - Speedlite AF Focus Beam Assist Tests
« on: December 13, 2012, 11:43:57 AM »
My serial is xxxxx4xx5xxx and has the IR focus issue. I've had it for 2 weeks from an authorized seller.
In -2EV of light my Rebel 550D was faster than the 5D3 (1/2s vs 1s). In 1EV of light the 5D3 is faster. The test was simple. Fully depress the shutter simultaneously on both bodies to see which shot first (images were in focus).
[The setups were different (5d3+600ex+70-200ii vs 550D+580ex2+24-70v1) but I found in previous tests that combinations of lens and flash did not make a difference to the outcome. Subject was a uniform tiled wall at 8 feet.]
