GH5 focus excellence

When recording how are you using tap to focus? I can't do it in mf or af-c.  In MF mode I have to drag the box, in af-c it brings up the dialog and asks you to "set" the new focus area if you tap the screen.. I wouldn't really consider  that tap to focus.  Because when you need two taps to focus + lag of dialogue box which takes 1.5 seconds to activate.

No GH5 here yet, but as far as I could understand from what I've seen from other users' videos, in MF, you have to drag it, right.

In AF-C, it is the way you describe.

But, you can always use it in other AF mode than AF-C or not?

As for instance here:

We've conjectured that some of the significant AF differences we've seen in different GH5 videos is the result of differences in the lenses themselves. I've always gotten great AF results from my 14-140 and although my 15mm 1.7 is good, it's not as quick as the 14-140.

I think it's definitely a lot to do with the lens being used. The 14-140mm was always designed for video so has lovely AF. I have always found the 20mm to be truly awful for video AF. It hunts all over the place and is just not any good. As always, for photo it's fantastic but video, not so much - though a lovely lens video quality wise. It will be interesting to see how all of the AF lenses stack up on the GH5 as more people play with it.

Indeed. Reason why I had asked it to the Max/Joseph GH5 test partnership... Unfortunately, people don't seem to care about. The devil is in the details ;-)

Ken...do you think it's due to the 14-140 being a more "video centric" lens than the 20mm...I have the 4.0 version of the  14-140 and even it is noticeably smoother than the 20mm...and I think in all these AF tests the different results may well be due to the lenses used in the system...though I don't use Canon, I imagine the AF between a Canon mount Sigma 18-35 and a native Canon lens also differs significantly?

True. Moreover, I guess GH5 settings may contribute to ease the issue. Actually, I'd like to see testing to fit so well together. Filmmaking is a combo match. People tend to forget it at times.

I've been following the GH5 concerned threads quite carefully, but never found anyone commenting on this. How, if at all, does the AF work with a Canon lens adapted through the Speedbooster (after firmware updates)? I'm interested in both stills and video.

Wondering on the same here...

Has Neistat moved over permanently to the GH5 now?

Just curious as if you look at his latest vlog when he's doing a piece to camera on the bridge where he proposed to his wife then he must've had it in the hitherto unknown Bridge Detect AF mode....

Yeah, he said he made the switch until something better comes along. That being said, he is also using a Sony RX100v, which was what he was using on the way back from the bridge when he fell and broke his finger. But I think it was the GH5 on the bridge when it locked on the background.

I did ponder that it might be the Sony but wondered if he'd be bothered with the extra hassle of recording external audio.

Of course if it WAS the Sony then he'll obviously have to fly Max and PhotoJoseph in to get to the bottom of it ;)

BTW, there's no XL 0.71x version (from minute 01:19), but only Ultra 0.71x.

XL version is only 0.64x.
