Probably. According to this article, the A7RIII can do it: https://petapixel.com/2017/12/20/amazing-tethering-speed-sony-a7r-iii/ How are you going to power the camera for 24 hours? If you go with ...

Sorry if I missed this, but why not do this tethered?

Why would you think changing jpeg to ARW would ever work? Those are two completely different image formats. My point was about changing arw to ARW, or vice-versa, depending on what the app was ...

I didn't find a full transcript of the interview, just excerpts. Can you link to it? I did find the video, and it seemed very directed (by Leica) as to the "questions" the interviewer was asking. T ...

Just a guess... maybe try renaming the .arw files to change the case of the extension. It may be that the app is looking for all lowercase or all uppercase, and the files are, by default, the ...

Except that he's having to push the lens away from the contacts to make it work...

Sony introduced a 24MP full frame camera with IBIS in 2008. In 2018 their most popular full frame camera with IBIS is also 24MP. So, yeah, some of the capabilities have hit a sweet spot. DR and ...

Even still. Nikon added those electrical contacts to F mount, which is 2mm smaller than M, and Leica themselves added contacts for their six-bit coding of M lenses. I don't really buy this ...

The Canon STM 40 is actually $199 new. The Sony 50/1.8F is $249 new. Both use stepper motors. The Sony is a more complex lens, though. Both are pretty good value and not that different in price. Th ...

No. This is a common mistake. The mount is E mount. It is E mount in all Sony MILCs, whether APS-C or full frame. The lenses are E for APS-C and FE for full frame.

You got a good price on that camera. I just bought one... well... bought it almost a month ago and still waiting for it to get here from Japan. I wanted one because I kind of collect a bit, but ...

My main one is an A7R2, but I still have my A7II as well. I still haven't decided whether to sell it / trade it for an A7 to convert to IR, or to have the A7II converted. Once I have an A7x for IR, ...

"M mount was not designed for digital." A much more provably true statement. In both cases, I don't see what kind of traction a marketing department gets out of saying things like this, unless ...

Certainly. That's a hold, not a toggle, but, sure.

And here's a thread where Prof. Hank put one on a focal reducer to get a fully circular image: https://www.dpreview.com/forums/thread/3699113

So? Seems to work just fine.

OK. No, you can't assign the one button to toggle lock of both with a single press. You would have to assign AF/MF toggle to one button, and AEL toggle to another button, and press both.

Tough decision. A D600 can use most Nikon lenses made over the last 50 years or so. There are a lot of options, including Nikon screw drive AF lenses that are still very good, but relatively ...

I have the Opteka 6.5mm for Nikon mount. I mainly use it on my NEX-7 for IR. I have the Fotasy helicoid adapter to allow better focusing with the IR offset (also allows fisheye macro). I don't ...

If you want it to toggle, then you do the "or" I posted: "... set it to toggle AF/MF." If you want to hold the button the whole time, then set Focus Hold, as Rich mentioned.
