Panasonic G100 flash question.
- Thread starter jonno35
- Start date
I admit I exaggerated the flash speed limit, I wasn’t aware it is a big issue here. I have two units, it does big wonders with my type of professional work. Single only disappointment is not the absence of image stabilisation, use of flash however limited, in particular when I use G100 with the Laowa 50mm and Godox macro combined. If there is a possibility then there is no such smallest set up for 2X magnification

You and many others.
They were probably compelled to add a viewfinder otherwise it would just be another GX camera. Unfortunately that only adds to the cost and makes the specs for stills look uncompetitive with other low cost cameras with a viewfinder.
Maybe they were counting on the new tracking audio system that nobody seems to care about!
Oh boy!

That's useful to know.

Not being pedantic? You jest ;-)
Or perhaps you could tell me - quantitively - the difference between "less than 1/50 second" and "a maximum of 1/50s".

That's kind of the point, Panasonic's G100 flash sync specs are non-specific "less than 1/50 second" so we can't really use that information to accurately determine the maximum flash sync speed.
This is from amateur photographer, very simplified summary regarding shutter and flash setting properties
amateurphotographer.com
The G100 features a fairly basic shutter mechanism that consists only of a rear curtain. The image capture process is started electronically, with the rear curtain stopping the exposure. This means that flash sync is a rather feeble 1/50th sec, but as this isn’t the sort of camera that’s likely to be used much with flashguns, it shouldn’t be too much of an issue.

The OP has established that HSS works at up to 1/500 sec with a Godox flash through someone he knows that's just bought the G100.

Maybe somebody is able to help me. I’m using this camera and just bought second hand Godox MS300 strobes with a Godox Xpro o trigger. Everything is fine at 1/50 but at higher shutter speeds (with hss) activated on the trigger I get those black parts at the lower part of the image.
I find it strange as there are people where it is working. (As mentioned above).
what could be wrong? Is it the camera, a setting in the trigger? I can not find a solution.

I wish I could help, but at this point I am completely puzzled.
What I get, using HSS on an X2 trigger:
- With TT685 all is well. Works as expected.
- With TT350 about half the frame is slightly dark with a sharp cutoff. Useless. Shows at all speeds above 1/50.
- With AD200 top and bottom of frame shade off noticeably. Usable for some purposes, but certainly not idea. Shows at all speeds above 1/50 but seems slightly worse at higher speeds.
What really puzzles me is I did tests back in December when I got the G100 and all seemed well then. Don't know if my testing was flawed or some setting changed in the trigger or camera, or what. (I have not done any firmware upgrades, so that's not a factor.)
So ya got me.

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
HSS on, 1/50 f8
HSS on, 1/100 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.I had the AD100 set up for eBay photos, thought I'd use the setup for a little more testing.

I used to be indecisive but now I'm not so sure.

Interesting. Thanks.
As I said above, I'm a bit puzzled. Wonder if it's something with Nissin vs Godox, or if maybe something changed between the original G100 and the D version.
I'll be doing more testing as I get time - I'm using the G100 as backup to my G9, so I need to know what works, or doesn't.

You may have changed the shutter type. Check that the Shutter Type is not set to EFC (Electronic Front Curtain) as this may cause the shutter shadow to show in the photos when using HSS. Make sure the Shutter Type is set to MS (Mechanical Shutter) and try again.

Gato said all seemed well when first tested back in December. On my G80 with Godox TT350o set to HSS, the shutter shadowing problem occurs when EFC shutter type is used with fast shutter speeds. When MS shutter type is used there's no problem. This is why I suggested Gato carry out a test ensuring MS is set and not EFC. It's a way of ruling it out if it turns out not to be the issue.

I think you'll find that "less than 1/50 second" doesn't include 1/50th itself, but "a maximum of 1/50s" does. I'm not sure that's what Panasonic meant, though. Probably something lost in translation.
Always a fan of a bit of pedantism now and again. ;-)

So am I, when it matters. But does it matter here? That's why I asked the question above: 'Or perhaps you could tell me - quantitively - the difference between "less than 1/50 second" and "a maximum of 1/50s"' when challenged.
It was only rhetoric of course; the camera uses 1/50 by default, slower but not higher speeds can be chosen, so "a maximum of 1/50s" rather than "Less than 1/50 second" is demonstrably more accurate, despite what the Panasonic website says. As you rightly say, probably something lost in translation. who knows.
My original assertion was "Panasonic quotes a maximum sync speed of 1/50s - and I have no reason to disbelieve it" was in challenge to some misinformation that had been posted. I didn't quote the source of my information (I should have!) but it was obviously not the website (which is wrong) but the G100 user manual, page 230:
This matches reality, and I summarised it as "a maximum of 1/50s". I'll take accuracy over pedantry every time

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.
