Thanks for your review!

You're welcome!

When you tested 70-200 2.8 ii in continuous servo, were you in focus or speed priority and what where your findings?

Did you get many oof shots? Did you notice difference in fps between focus and speed priority? Did you notice difference in af speed between 135L and 70-200? Thanks!

There's a a confusion running around regarding this.

There's no provision in this camera to prioritize shutter release over achieving focus and vice-versa, in continuous AI-servo AF shooting, as there is the 1D series (the function is called "AI Servo 2nd image priority" in those models).

Instead, it so happens that "High Speed Continuous Shooting" + Servo AF has been biased to maximum frames per second at a possible expense of focus (approximately 5 fps) whereas "Low Speed Continuous Shooting) + Servo AF has been biased to focusing, resulting in a maximum attainable frame rate of approximately 3 fps.

This has been hard-programed in the camera and can not be changed.

I got the specified rates out of the camera and most frames were in focus, at a slighter lower rate than with my 5DMKIV (...which is extremely good, when it comes to in-focus frame ratios in AI Servo continuous series...).

Overall, once one accepts the specified low frame rates, things are not bad.

It is the (in)ability to keep track over the EVF split-second freezing that might be a problem in fast-paced action scenarios.
