I bought a G100 about a year and a half ago.
Aside from a couple of UI differences from their upper level bodies (reduced button/dial programmability) that were a little annoying, it was a very functional 20MP M43 body, with excellent color rendition and output overall. When compared to the GX9 output, it was just about identical, and I think a little nicer, in terms of WB and color rendition, than the G95, at least for SOOC image use.
However, the EVF was cranky. I had to have my eye exactly centered and a little set back from the eyepiece to get the image correctly in focus across the frame, and the EVF color accuracy was not great. I sometimes use glasses (sometimes not) with the EVF, and this made that kind of difficult. So, I found myself not using the camera much because of that.
As an added conundrum, I had bought the kit with the tripod/handle with the intention of also using that on my other Panasonic bodies, however it turned out that because it was a micro USB plug not USB C, it only would partially be compatible with the other bodies when used with a micro USB to USB C adapter. That was a frustrating discovery.
So, when they came out with the new version, (the current D version), which solved the EVF and tripod compatibility problems, I started thinking maybe I should take a look at that, and maybe trade in the original for the new one, if the improvements were significant enough.
I went back and forth with this for several months, and had decided to just sell the original G100 and have only the G95 for the M43 and the S5 for the FF (with the old faithful GM5 for the quick portable kit). Too much camera churn is not always helpful, after all, you know? (I am sure you all are giggling heartily at my actually saying that, given my gear history...)
But, I ended up selling a whole batch of gear to MPB, and generating enough funds from that to cover both the OM 90mm macro and about half the cost of the new version of the G100, so I said what the heck. Life is short, and I really like having two M43 bodies; one for long use (the G95 with the PL 100-400mm is a VERY nice combination), and one for short and portable. And, the new version of the tripod/handle that comes with the G100D is fully USB-C and cross compatible with all of my Panasonic bodies now, which makes it finally genuinely useful for my purposes.
So, the new G100D arrived today, and I will tell you, the EVF difference on this one vs the original is HUGE. I do not have to aim my eyeball just right to get a clear image; I can put my eye to the eyepiece and see everything, the color rendition is much, much, more accurate (it agrees with the rear screen also), and I can use it with or without my glasses.
The rest of the camera is pretty much the same; color rendition is great, the same little annoying button/dial programming stuff is still there (unfortunately); in other words the good and bad of the original is still there, other than the EVF, which is a genuinely significant improvement over the first version.
So, this is either good or bad news, depending on how you use the camera. If you are not a big EVF user, the original can be bought at bargain rates, and you get a very competent small camera with excellent output. On the other hand, the sale prices of the new version are very competitive and you get a truly useful EVF now, if you need one.
Not a bad choice of options for a small M43 body with excellent output....
