Remember that in the other half of the world (half might be exaggeration since I don't think it includes Asian market cameras), they have to pay that special tax for video products that can record more than 30 minutes, so considering that tax, the price is pretty close to what we will pay over here in the USA.

Think of "high" and "low" as the frequency at which it will detect. "low" frequency means it will be very generous with what it considers to be in-focus. "high" frequency means it'll only highlight the highest-frequency details, which means it will be much pickier about what's in focus. At least, that's the way the DVX200/UX cameras work, I'm presuming the GH does it the same way.
DAn CHung at Newshooter: Atomos just released "...4K 60P 10-bit 4:2:2 external recording with the Panasonic GH5. This much anticipated feature gives the diminutive camera high bitrate Apple Prores recording at a better bit depth and frame rate than any other mirrorless competitor." Also he says you can record 180fps internally simultaneously while monitoring/recording 60fps on inferno. http://www.newsshooter.com/2017/02/...shogun-inferno-at-bsc-expo-with-sample-video/

I have a question about SD cards, for 150mb/s 4K recordings, do I need to use SanDisk Extreme PRO UHS-II (300mb/s) or can I get away with the Lexar media at 150mb/s. New to recording such high resolution media, perhaps this isn't an issue with the GH4, I haven't used one, just trying to clarify to plan for media possibly in the future.
MB is short for megabyte, Mb is short for megabit. 1 byte contains 8 bits. So in this case, the capitalization is significant. The recording bitrate for 2160p60 on the GH5 is 150 Mb/s (megabits per second) which is 18.75 MB/s (megabytes per second). So basically you need a card that can sustain this minimum write speed.
Cards with a UHS Speed Class 3 (U3) designation are supposed to be capable of a minimum write speed of 30 MB/s which should be sufficient for the 150 Mb/s (18.75 MB/s) recording mode on the GH5. Panasonic has planned a 400 Mb/s (50 MB/s) All-I recording mode which will require cards that are faster than the U3 minimum write speed. But for other recording modes, I would expect U3 cards to work.
Keep in mind that most SD cards advertise their read speeds much more prominently than their write speeds. Because the read speeds are usually faster. So the Lexar Professional 1000x SD cards you mentioned have a read speed of 150 MB/s, but a write speed of 80 MB/s. That should still be plenty fast enough, but it's not quite as fast as the read speed.

Thank you for this information, so record times are generally 1GB per minute. Approximately? Was trying to figure out space I would need if I ever moved to these cameras and 4K.
Since the Video Speed Class (V speed) ratings are still pretty new, many SD cards currently being sold do not include a V speed designation. But I'm sure this will become much more common in the future.
A lot of the cards currently available only list one of the original Speed Class designations (up to Class 10 designating 10 MB/s write speed) or a UHS speed class designation (up to U3 designating 30 MB/s write speed).
This page from the SD Association has a pretty good overview of the different Speed Class designations that have been used for SD cards:

I won't say "need".
I will say "should". These are simply the best, most reliable cards out there. Why take a chance?
Stabilization comparison between GH4 and GH5. Looking good.
Since the GH5 doesn't have an AA (low pass) filter over its sensor, does that mean the sensor has NO protection at all? I tried to google the answer but couldn't find anything relevant. I don't know if anyone here would know, but I thought I'd try just in case.
My concern is that I've always used the Copper Hill method (statically charged dry brush) for cleaning sensor spots. Since every camera I've used this on has had its sensor covered, it hasn't caused any problems. But I'm worried about doing that on a GH5 if the sensor is completely unprotected.

Not naked! I has the cyan IR cutoff "hot mirror" filter in front.
Fantastic! That's a relief; thank you so much, Peter.

Out of curiosity...and this is a serious question...how do you manage to get dirt on your sensor? I have to clean my lenses, sure, but the sensor is never uncovered for more than a very few seconds at a time.
I have a magical power. I've had it since I started using my first dSLR, the Canon 40D. I can sometimes get dirt on the sensor even with never having changed lenses. However, with the GH4, it's a far less common occurrence than with the dSLRs I used (the Canon 5D2 was the worst).
I am always very careful when I change lenses. I try to do it very quickly, with the camera blocked from the wind (if outdoors), yet inevitably I will eventually get some sensor dirt.
However: Please note that I find sensor dirt that others might never see (nor me, unless I shoot at crazy small apertures). I use a lighted loupe that magnifies the sensor and clearly shows the smallest piece of dust. So it's entirely possible that I clean more often than I have to (sometimes every day, sometimes once a week, when I'm out shooting all day).
This is an interesting question. Historically Micro 4/3 cameras have had a 4mm filter stack in front of the sensor, which includes AA and IR filter layers. And as it turns out the thickness of this filter stack does actually matter and can have an effect on image quality. The Metabones Micro 4/3 Speedbooster adapters (as well as Micro 4/3 lenses, presumably) are designed with this 4mm filter stack in mind and without it, image quality can be reduced. More of the technical details about this are here:
https://wordpress.lensrentals.com/b...in-the-path-sensor-stacks-and-adapted-lenses/
What this likely means, is that when Panasonic removed the AA filter from the stack on the GH5, they probably replaced it with a thicker piece of optical glass so that there is still a 4mm filter stack in front of the sensor. I think they would have needed to maintain the 4mm thickness for consistency with existing Micro 4/3 cameras and to maintain optimum image quality with Micro 4/3 lenses.
But in any case, I believe pretty much all digital cameras have some glass in front of the sensor.
