Hi , I'm thinking of getting the Panny G,100

What's bothering me is the 1/50 flash sync.

Can anyone tell me whether HSS can be set using an external flash or does the E shutter stop it.?

Thanks
 
G100 do not have mechanical shutter only electronic
According to Panasonic the G100 has an "Electronically-control focal-plane shutter".
so the flash is limited to 1/30. I wasn't aware that third party flash able to overcome this.
I don't know that it does.
It has the one-curtain shutter, which goes back at least to the GM series where it was needed to achieve the very shallow body thickness. The drawbacks are auto-switching to e-shutter at 1/500 and above--basically any time you're in sunlight, dropping image bit depth, and severe rolling shutter effect. IDK whether those issues have been tamed in newer models using that shutter.

Cheers,

Please stop this misinformation.

You get full real actual 12 bit RAW (not 10 hits in a 12 bit bag). All luma values are available for use, not just every fourth value. I've already demonstrated this on a previous thread.

I can't vouch for burst and bracketed shooting - I wouldn't be surprised if it drops down to 10 bits in a 12 bit bag, but haven't tested it yet. Maybe someday but I rarely shoot in burst mode.

But in single shot, all 12 bits are available for use. There are plenty of reasons to despise this camera, but this ain't one of them.
Well, I'm truly sickened to say this but it turns out, even in high speed burst (6 fps FTW y'all!) when using e-shutter on the G100, you STILL get actual real full 12-bits of RAW (not 10 bits in a 12 bit bag).

AFAIK, previous Panasonic models using the sabotaged tiny-and-efficient EFC-only shutter couldn't pull this off. My lowly wishes-it-were-a-G9-but-it's-merely-a-humble-G95 can't fire bursts in e-shutter without dropping into fake 12 bit mode!

It pains me tremendously as I am yet again thoroughly disappointed and nauseated to give the haters one fewer reason to loathe the G100.

Apologetically yours,

A G100 Owner

I have a Flashpoint TT350 (Adorama-branded rebadged Godox AFAIK) and whether mounted directly on my camera's hotshoe or used with my XT1 wireless trigger, the camera body will not allow shutter speed to be set above 1/50sec. It doesn't matter which mode I put the camera in (there is no high speed sync option under flash settings). It doesn't matter what mode I set the flash or the wireless trigger to. The camera body does not allow me to shoot a shutter speed higher than 1/50s.

I'm not even sure how you guys are triggering a flash with speeds higher than 1/50s when my camera won't even let me try it.

What's the secret sauce here?
 
Thanks for the ideas. I will double check the shutter setting and should have time this afternoon to do some more testing.

Will let you know what I find.

Is the misinformation re. the GM series or the G100 or both?

Thanks.

I'm using a Adorama R2-TIIo trigger and setting HSS on the trigger. (I think that's the X2T-o in Godox branding.)

I'm going to find time today to do more testing, will report back if I find anything new or interesting.

The misinformation you (and cba_melbourne has recited in the past) is about the G100.

There have been overgeneralization errors. The G100 and the GM series have the same shutter, ergo the G100 is a 12-bit faker when using eshutter or burst mode. This is decidedly incorrect regarding the G100, and as I've said repeated, I'm extremely sorry to tell you.

That being said, I don't have a more-precious-than-gold-ounce-for-ounce GM1 or GM5 so I have no empirical basis to dispute whatever conventional wisdom has developed around its 12-bit fakery. Of course, I have no reason to doubt it, since my much newer Lumix G95 is also a 12-bit faker when shooting in some higher speed modes.

I've just checked the G100 review on this site and it seems like the shutter type on this camera is EFC and E shutter only. I didn't see any mention of MS shutter type, which may explain the shutter shadow with HSS mode assuming EFC works the same as my G80.
Will let you know what I find.

While I have used a G100 I don't own it or have files from one to fiddle with.

Panny can have my money should they release a "G200" w/ IBIS and full shutter. Doubt that day will come but in case they're watching.... Would be a nice upgrade from the GM and still small for that Just-in-case camera. As it is, no.

Well, personally, I wouldn't let small details like not owning a G100 stop me from spreading misinformation about the actual bit depth of G100 RAWs. People really shouldn't own this camera, so please carry on.

You can already buy a G200 — it's called the Olympus EM10IV. What are you waiting for?

Gosh, I wonder.
 
I’m able to select HSS on the trigger (xpro) and then select the higher shutterspeeds. Though it doesn’t matter as I can’t use it. For the time being i probably will get an ND filter as the strobes are way to powerful with the 1/50 shutterspeed.

That's interesting. On my XT1 it doesn't matter if I set HSS on the trigger, my G100 it won't let me select any shutter speed higher than 1/50s. Maybe there's a firmware restriction blocking this my with trigger (and/or flash).

I should try it on my G95 and see if it behaves the same. Not that it makes a difference for the G100 but now I'm curious all the same...

Interesting, because mine does work with the X1T, also with the X2T. Mine are both Adorama versions, but I don't think that should make a difference. So do test with your G95.

I had the AD100 set up for eBay photos, thought I'd use the setup for a little more testing.

All photos with a Godox X2T-o on G100 with kit 12-32 lens. All at flash white balance, AD200 at 1/4 power, ISO 800. Shutter and aperture as noted. The color is a bit off because I was bouncing flash from an off-white wall.

All photos are unedited camera JPEGs, just reduced size for web use.

1/50 f8 with HSS off
1/50 f8 with HSS off

HSS on, 1/50 f8
HSS on, 1/50 f8

HSS on, 1/100 f5.6
HSS on, 1/100 f5.6

HSS on, 1/200 f5.6
HSS on, 1/200 f5.6

You can see the shading in the last two. You can also get an idea of how much light ia lost with HSS, also a color change with a shift toward red.

Side note: The camera in the photos is the first serious 35mm I ever owned, a Canon FTb bought around 1972 or '73.

I have a Nissin i40 and a i60 and don't have these problems. I've used them on FZ1000 G9 and G100D , HSS has been good on all of them.
The FZ1000 has a leaf shuffer, no HSS required up to 1/4000th. The G9 sync speed is 1/250th if I’m not mistaken.

anyway, did you try with an even white back/underground as Gato used? Otherwise it would be much less visible.

whilst the slow sync speed is a potential reason for me to never buy the G100 (lack of IBIS is another), the slow sync speed doesn’t have to be an issue. If there isn’t a ton of ambient light, the sync will freeze the action. And contrary to the rule to set the camera so that without the flash the frame is dark (flash controls all effective lighting), it can actually be very useful to use slower speeds such as 1/50 or slower to let in a bit of ambient light. More natural look. In many cases, you don’t need hss and can simply use 1/50th for great flash results.
 
For what it's worth.. Using.my flash pointing straight at a white wall 1/200th HSS does cause a slightly darker area towards bottom but swinging the head around and bouncing off the ceiling behind me seems to even the coverage out. I rarely if ever point my flash at a subject.
 
Hi , I'm thinking of getting the Panny G,100

What's bothering me is the 1/50 flash sync.

Can anyone tell me whether HSS can be set using an external flash or does the E shutter stop it.?

Thanks
Lol I own a G100 and I was pretty sure that with external trigger it goes up to 1/500, the irony of this as I've been looking to buy a flash these last 2 days lol.

For me it was Markus Pix in this video
(at the 15min mark) says exactly the above

I can recommend Nissin i40 and i60 they are both small and have good guide numbers and with HSS enabled you definitely get 1/500
 
Ok so in theory at least I could use it on HSS right? But up to what speed? 1/500?
I get 1/500th no problem with my Nissin i40 and i60 but it seems some Godox won't do it. I suggested it to a YT reviewer Brian James "That Micro 4 3rds Guy" and he was using a Godox and it worked for him , maybe if you look at the video,he was saying the G100 was a nice stills camera.he may divulge what flash he was using.

I've saved you the trouble he was using the Godox V10. No experience of it myself though.
I used to be indecisive but now I'm not so sure.
