Some people forget that F aperture is not (just) about bokeh, blur, etc. its about the amount of light which can reach the sensor. In that matter the F value is equivalent between FF and APS-C.
I don't think so. Aperture is about the diameter of the blade iris. The amount of light actually conveyed to the sensor is measured in T stops.
Regardless of the light transmission, an f/1.8 aperture will produce the same exposure at the same ISO and shutter speed whether full frame or crop. I think that's what he means.
If my depth of field is that tight and the possibility of focus shift is evident when using this method, I'll quickly turn on live view, zoom in a bit, and achieve focus MANUALLY. Practice a bit, and this gets fast.
Nikon's 3D tracking = Canon's AI Servo.
There's also Live View focusing that might work for you
I see... I just foud out what you can not do with the 6D. I was just interested in this cam, but I think not anymore.
I wouldn't call it a deal breaker just something you have to be mindful of. It also something that can't be overcome with good technique or simply realizing the limitations of what you and cant do. Is it fool proof? No, but then again nothing really is.
Well by the nowdays tech a decent 3d tracking is something that I personally would expect in a ~2000 € body.
I don't think we are talking about the same thing. Focus and recompose to me (and to pretty much everyone) means you lock focus on the subject then recompose the frame (by moving the camera) then click the shutter. This does shift the focal plane and if you are using a razor thin dof you'll end up with some back focus most likely. 3d tracking? I have no idea what you are talking about unless you are simply talking about servo mode in which case I don't think you'll be using focus/recompose. What exactly do you want the camera to be able to do for you?
