Interesting. I have found Darktable to be quite fast on some rather mundane laptops (8-core Zen 2, 4-core low-power Ice Lake). I'm only using it on a 24MP camera, so people with megapixel-monsters...

Right -- nor should they.

Point is, it's simple to do write verification if you want to, and it's simple to automate it.

And while not every photographer needs to know command-line tools, it's...

cp * ~/Photos/somewhere/
md5sum * > checksums
md5sum ~/Photos/somewhere > checksums-2
diff checksums checksums-2

I don't think there's anything wrong with Nikon being "late" to mirrorless. They are a very conservative company, and they made excellent DSLR's: the D6, D500, D850, D7500, and so on are all superb...

There are lots of them in use, though. At the local eagle nest there's me with my D500, someone with her D7500, a guy with a D850, another D500...

Hogan says some very positive things about Nikon's engineering. When he criticizes them, it's messaging and marketing, not the cameras and lenses. A few quotes:

"Once we early adopters verified...

The 300PF is a magnificent lens.

Thank you for your service as a FOSS developer!

Looks like a great option for people who want a bit longer than the 300mm but shorter/faster than the 500mm. Nikon long prime shooters are spoiled for choice:

300 f/4
400 f/4.5
500 f/5.6
800...

I waited for ~6 months to get a 500PF (and this was quite a while after release, too.)

This is a good thing to some degree for Nikon. Having lots and lots of people who want to buy your products...

Yeah, I'm not keen about the logos. The ergonomics on the old DSLR's were fantastic -- my D500 is basically perfect. I'm less keen on the Z6 (which I use), but I've taken a look at the Z9 and it...

I was the pianist at a friend's wedding last year. The photographer was a local high school photography teacher, and I saw she had a 28-70 f/2. I held some strobes for her for an outdoor setup...

Nikon is also *out there*.

My town is a hotspot for birdwatching in the winter -- we have a bunch of eagles that show up. There are Canon, Sony, and occasionally Fuji and m4/3 cameras represented,...

There are also F-mount lenses that work fine and can be adapted if you really need one of these options.

How is that lens for astrophotography? I am using an adapted Sigma 14/1.8 and am less than impressed with some of the optical issues (serious field curvature) for astro work.

Per https://campus.murraystate.edu/faculty/tderting/anatomyatlas/salee_shaw/hawktunics.html a hawk's fovea has a million cones per square millimeter of retina. That corresponds to each cone being 1...

Also, smartphones spend their days in people's pockets, and if they're in the places where interesting photos get made, they're probably sweaty and a bit scratched.

I treat my Sigma 14/1.8 a lot...

So, I have a Z6. It was a workhorse for online teaching and got used in a chalk-dust-heavy environment for a year. (My priority was the students rather than keeping the camera squeaky clean.) Now ...

These aren't nuclear reactors; they are radioisotope thermal generators.

They are indeed reliable -- they power things from Voyager 1 and 2 to some old pacemakers (and those pacemakers work...

Interesting question! I was shooting with the camera braced on something at 1/2 second (difficult with a 700mm!) because I left my tripod at work.

But the "rule of 600" says that the slowest...
