Focus Tracking Differences between Sony’s E-Mount and A-Mount Cameras by Gary Friedmann
Gary (video on top): “As I mention in my blog (friedmanarchives.com where this video first appeared), there are a lot of people for whom this situation may never come up. My purpose with the video is to let people better understand how the cameras evolved, and to touch on the strengths and weaknesses of each platform. It’s always useful to know under which circumstances your equipment will hit its limits, even if you never push it that far.”

Bernhard: “I started a little blog about my recent switch from my Canon 5DMKiii to a Sony A7s: http://www.wimair.at/WP/?page_id=3760. It’s written a little “personal”, to tech charts – only real life experiences. And it’s german only, so it may not be interesting for you. As you sometimes post blogs of readers I thought you may like it.“

oh boy, no one here. hi Gary 🙂
It’s allways interesting to watch Gary’s videos. thumbs up ones again 😉
Informative video. Leads me to believe however that an A7s with stabilization may not happen due to noise when in video.
It seems the problem is more af-c than whether there is a mirror. What am I missing? I mean, Sony simply doesn’t allow you to change the aperture with slt cameras in af-c according to this video, but does if there is no mirror, for some reason.
Aperture is lock only in video recording – as Gary explained why it should be.
so that’s why my A55 is far better in AF-C than any mirrorless alpha.
I was expecting to see true focusing differences…but then there was no comparison in speed and tracking with a moving target.
Why I haven’t seen a A6000 vs A77M2 tracking comparison yet?
Video is so dumbed down to the point of being wildly inaccurate.
Friedmann really understands this!
Does the aperture on a Nikon or an A99 actually open all the way and then shut down to shoot 6 to 11 times per second while doing tracking focus?
Reading some of these comments I am sure, that you can’t take donkey to University in Bourbon and bring back home a horse … can you …
Everything has its place. I’ll take both A and FE for now.
Does anyone really shoot in AF-C at F25 though? Even F13 seems kind of unlikely and below that the problem didn’t seem significant.
My most excellent Canon 5D3 wouldn’t focus beyond f/5.6 (i.e. with doublers on a slow lens). These reviewers aren’t photographers, they’re simply poor wannabe reviews. Setting effect off in the menu……..
Yes, on A99 it does in PASM mode, but not in AE Priority Continuous Advance.
I’m sure same goes for any Nikon or Canon.
Jut tested this on my A65 and have no reason to believe that A99 is any different.
Thanks Stan. This is very interesting. It suggests creating a mode setting on Mirrorless cameras to do the same thing for superior tracking at the expense of live view.
