So I've never owned a camera I felt confident enough to trust in AI Servo until I started shooting with the 1Dx. Old habits die hard though, and I'd still been toggling between one shot and AI-Servo based on subject matter. I've always held this pre-conceived, personally unfounded notion that One Shot would be more accurate than AI Servo on stationary subjects. Given how amazing I found AF accuracy to be on the 1Dx, I decided to test my theory by exclusively using Servo mode for all non moving subjects.
In the past month I've shot mostly portraits, some landscape, and quite a bit of macro. At the pixel level, I can't tell any difference in regards to focus accuracy between shots taken using One Shot vs. AI-Servo based on my real world use. Granted, I have my shutter release priority biased towards focus as opposed to release. I don't see myself using One Shot ever again as far as I'm concerned, and I appreciate not having to press a button or switch modes to engage Servo if something does start to happen unexpectedly.
Can anyone think of any cons to using AI servo fulltime and ditching One Shot if I I'm able to achieve the same level of accuracy? (ok yes, as a concession I'm taxing the battery, but battery life has become a total non issue for me having moved to a 1D body)
Thanks in advance!
i shoot my eos m in servo full time its faster to focus and accuracy is good however i still shoot single shot 99% of the time on the 5Dmk3 and use the Dof preview button to engage servo on demand IMO this is the most awesome feature of the 5Dmk3
