We sold our 24-70GM and got the Tamron. The Sony is objectively a slightly better lens (in every way but size and maybe sharpness), but size and cost won in the end. I guess the Tamron also seems to have fewer issues with CA (not that it's bad at all on the Sony).

I went to The Wedge Overlook in central Utah on Thursday night for some astro. Ended up with a couple shots that I figured I'd share. This is the first time I've blended in separate foreground exposures so C&C is welcome. Thanks.
16-shot 20 second stack for the sky and a tweaked blue-hour...
You just made assumptions again. I never said I wouldn't turn it off, and in fact I never would have turned it on if people did not want to do it.
People do use headlamps to hike along there as going without one on a moonless night would be deadly. There was much more impactful light pollution...
You've just made assumptions and stated opinions as fact.
First, there were in fact other people there and we all agreed that it would be useful to set up the light; and they indicated that they liked it. We moved it a few times for different shots.
Second, this form of lower magnitude...
It's lit using a Neewer 2" LED panel at its dimmest setting from ~150 feet away. It's lighting up that whole area just enough to make the foreground stand out. The low level lighting concept works really well for objects that are close enough that they can reasonably be lit and can look much...
As requested, a 100% crop around the lagoon nebula.
I'm not super happy with the slight fringing around some of the stars, and pretty sure that the exposure was a little too high and blew out the real colors in most of the stars. I also have no idea what color the lagoon nebula is "supposed"...
I've always loved the galactic center and the dark horse nebula. I recently purchased a tracker so I decided to get a little closer to it. This is my first time doing astro with longer than a 28mm lens so C&C is appreciated.
5 exposures at ISO 1600 and 30 seconds stacked using median to remove...
I'd wager those features add very little to the actual BOM and production cost for the lens, and consequently don't affect the price much (blind guessing on the order of 50 dollars). They are, however, features that some people really like. Since you can ignore their presence if you don't like...
There are some photos, especially with backlit portraits or landscapes, which just won't work without the right dynamic range or color sensitivity. You'll see them and think "I could do that with my old cheap camera" and you would be right - except that it would look like garbage even at web...
