Nice - thank you! I don't see the f/stop value. Unrelated, I cannot help wondering what -0.7 exposure compensation does at ISO 100? The SS was 1/10 s for the second image. Would changing this to 1/15 s be better than applying -0.7 exposure compensation when the camera is at its base ISO? Of course, the images are gorgeous, and my question is of purely technical nature - no criticism implied.

No problem! Here is the camera info in order I posted (all with the A7R III):
f/13, 20s, ISO 100, Aperture Priority
f/11, 15s, ISO 100, Aperture Priority
f/9, 1.6s, ISO 100, Aperture Priority
f/13, 1/10s, ISO 100, Aperture Priority
To you question, the 1/10s shutter speed IS the shutter with negative exposure compensation applied. If I did 1/15 or shorter it would be "greater" negative exposure compensation i.e. -1 EV or more. I am using exposure compensation here because I am shooting in aperture priority rather than manual. The reason here is that the light levels were increasing every minute or two as the sun was rising. Letting the camera choose the shutter was quicker and I usually find with this camera's metering shooting in HLG that applying some negative exposure compensation is necessary to protect the highlights.

Just got back from a quick run out to Utah. Here's a few stitched panos and some night shots. As has already been discussed in the other thread, sun stars and sun flare/ghosting resistance isn't one of its strengths, so if you're planning to do sunset/sunrise shots with sunstars, don't rely on this lens for that role. However, in almost all other circumstances, I loved using it and being able to use it as my primary lens except for a few lens changes for some shots with the 35GM for sunstar/flare performance and the 14-28 for some astro shots.
With as much moonlight as was out last night, couldn't really test anything besides coma. There is a little bit in the corners, but once stopped down to 2.8 it was mostly negligible.

this lens is a keeper.
its fast, sharp, and accurate. only real cons is its a little chunky, but it saves me from having to carrying a 12-24, 24-70, and 70-200. and i just have to use a 12-24 and 35-150 to get the coverage i need and want, so in essence its a much lighter kit.
these are shots from a family gathering, it never missed a beat.

Got around to editing a few more from the weekend.
My wife doesn't understand my fascination with these gnarly trees in the Utah desert, but I think it is pretty amazing how this guy grew up through a crack in the rock and then bent over back on the rock and stayed alive.

Here are some test shots, wide-open at 35mm and 150mm. Shot in RAW lossless and imported into Capture One, no processing other than C1's defaults, then cropped for the crop shots.
I have to say I'm really blown away by the sharpness (even wide open). I wasn't expecting it to be this sharp.
100% Crop, focus on the top right of the birdhouse near the nail

There are some differences. When looking at the placard:
The top right corner is similarly sharp at 35 mm and 150 mm.
The top left corner is visibly sharper at 35 mm vs 150 mm.
The bottom left and right corners are visibly softer at 35mm vs 150 mm.
At 35 mm, the softening along the left side of the placard (left from the viewer's point of view) on moving from the top to the bottom is quite pronounced.
There is some color fringing at 150 mm visible in the top line of text (and this is presumably after some corrections, and can be more pronounced in the uncorrected file).
Both images seem equally sharp in the center and along the central vertical and horizontal lines.
It does not necessarily mean that there is something wrong about the lens. At the end, it is not the sharpness that determines the artistic value of an image (mostly - unless you are a birder!). Nevertheless, some of us find this comforting knowing the behavior of the lenses attached to our cameras.
Cannot help this: seeing this placard evokes memories of my formative years in the Soviet Union. Political slogans were very common in the streets of Soviet cities.

Yeah, part of the softness at 35mm might be due to these all being hand held. I did try to get perpendicular to the sign, but at 35mm I'm close enough that the depth of field is pretty shallow, so it's easy to get sharpness falloff on flat plane (especially when not perfectly perpendicular to it). I'm still wanting to play around with it more. I'm looking forward to seeing what you find in your tests of this lens as well. The yard sign was something that had decent colors and I was able to make a few quick snaps of. Bear in mind the fringing you see might actually be in the print of the sign itself (it's not like it's a high quality print), but I can confirm tomorrow in the daylight. There were no corrections applied for fringing though. It's a shame we can't post images larger than 1.5MB here, these are pretty scaled down to get them below that mark.
I'm intrigued that you call them political slogans...none of the statements strike me as something that *should* be political, yet here we are .

Some more pictures I took from a walk today. Some very light touch-ups to colors, highlights/shadows. I took a bunch of pictures of the kids too (which turned out great), but unfortunately I can't share them on a public forum. I'm using Flickr this time so I can just post the full size images. EXIF data is intact if you click through.

Workout for Devin Haney today. Normally i would have to bring 3 lenses for this kind of shoot. the trifecta if you will, 12-24, 24-70, 70-200. now, i just bring a 20 1.8G and 35-150.

A few shots from GTNP today. After skiing until early afternoon, we headed into the park for what looked like either a 10/10 sunset or dud, depending on what lay hidden on the horizon. We lucked out and had a gorgeous cotton candy sky tonight. I must say, when the sky is changing every 15 seconds like tonight, it is nice to be able to make a 35mm stitched pano and then zoom right into a 100mm shot without a lens change.
Some Flickr pics for the 6K resolution (all HDR bracketed shots, panos are HDR bracketed and stitched, edited to personal taste):

Nice shots "turbodude", capturing the behind the scenes action.

Here's one from a walk with the family yesterday. This lens is so interesting, I used to have to think about which lens I wanted to bring on a walk if I wanted to snap a few pics of the kids/family, but with the range this lens covers, I don't think about it anymore. It's quickly becoming one of my favorites.
