Have to ditch the GFX setup for star trails. Outcome is brutally sharp with huge aliasing effects. Old 24MP FF cameras with AA-filters are quite good for those. Running moire filter as a gradient over the images did not help and neither did dialing in huge luminance NR before TIFF export and stacking. Dunno how GFX100 would work.
Gonna try misfocusing the stars next.
Did you try using "Enhance Details" in lightroom to see if that improves the aliasing? Another option could be to downsample the GFX files to 24MP.
For what it's worth, from what I've read, the GFX100 does not have the same issues with colour aliasing.
Mike, that is eye-catching color contrast right there between the blues and the yellow/orange. Superb warm tonality and light overall.
dakel, thanks for your suggestions. Will try those out, particularly the downsampling idea. Never thought I would have to step down in resolution due to brutal sharpness
Some more focus stacks! With 50R and GF50/3.5 of course
First one. 15x10sec stack with Helicon. All the way from MFD to the opposite side of the stream.
Seond one in moonlight (full moon). This is a super long stack of 6x2minutes with Helicon.
Front to back sharpness without tilt lens. No more tilt for me unless I'm using my Intrepid 50R and GF50 have so far been the best $$$$ I have ever wasted in digital cameras. I found nasty issues for some of my astro purposes but at IS0100 and on the tripod this combo just sings. What other system gives you intervalometer and advanced bracketing with 10+ minute exposures? No other system. Now I'm waiting for the winter and -30C conditions.
I had a little project during July 2020 - A Roadside Collection in Finnish Lapland and mostly during the midnight sun. I parked my car everytime I drove past some fancy looking spot and took a photo. Here are few from early July:
I've tried this shot a handful of times over the years but never got it quite right. Finally got some interesting light. Interesting light covers a host of sins.
Did you try focus bracketing with it? It was said to have very little focus breathing so the FoV should not change much and therefore it should be easier to stack close focused complex scenes better.

For some reason I can't quote your message directly, so pasted it in here ^
I haven't tried focus stacking at all, and I'm not sure I will. Every shot I've seen taken with stacking seems "flat" or "dead" to me, like it was taken on a smaller sensor, even though the detail and tonal range is still there.
Been thinking about what the deal is, and I came to the conclusion that a single exposure stopped down to f/11 or f/16, where everything at a glance appears in focus, our brains can still pick up on the subtle differences in focus acuity between distances, therefore making a non-stacked image seem more lifelike. Or maybe the focus stacking software/process causes a loss of microcontrast/contrast, I'm not sure.
There are many ways to stack the photos. Helicon for example offers three different methods. One keeps color definition "as-is", one is good for continuous surfaces and one is suitable for complex and busy scenes.
Stacking in Photoshop sometimes works but usually wrecks the stack in spectacular fashion, especially with landscapes.
Middle falls... That water is still cold. My feet ached then went numb. But while I was there some young idiot(?) did a backflip off it into the pool below.

Now that is one unique looking falls. I can imagine 27 tripods on that plateau at some busy evening / morning at the same time.
Maybe in the "heat" of summer but not out with tripods last weekend. There was a guy the evening before that did a backflip off into the pool below. These shots were taken early just after sunrise to avoid the people that like to get in your shot.
