Looking forward to that 150/1 FF lens! :)

Nope. However in a dynamic setting it might be nice to have as much sensor DR as possible. Lower ISOs are more noisy in the shadows btw. The whole purpose of variable gain is to minimize electronic ...

All sensors clip rather abruptly. No roll off. The raw file is either clipped or not, although some recovery can be attempted if not all channels are clipped. I would be surprised if DxO and Adobe ...

I don't. I try to maximize the exposure and let the ISO float. But I often find my self with the lens wide open and borderline shutter speeds when the light is low in order to keep the exposure up.

You can also specify at which minimum shutter speed ISO should change in aperture priority

Makes sense. Difficult to compete with the data rate of the a9 stacked sensor

How cool is it to launch such an advanced system in a6400! Very, very impressive

You can set the range of ISOs in auto as stated in the manual You can change the range of ISO sensitivity that is set automatically in [ISO AUTO] mode. Select [ISO AUTO] and press the right side of ...

Negative compensation will increase shutter speed if the aperture stays the same. A good a9 strategy in low light: Set the ISO to 640. Set the aperture as large as possible with respect to desired ...

And that is solid advice although it might be better to adjust the ISO when the image is developed to maintain highlight headroom as discussed rather extensively in this thread

I have a Q, but, unfortunately, no adapter for e mount lenses exist, and I no longer have any a mount lenses

After some solid advice you fell into the common misunderstanding that ISO is part of the exposure.

I think I could rig something up with my slide scanner 😉 https://jar.smugmug.com/Photography/Geeky-stuff/n-HbBKt/i-7sQN4nV

read this and be done with it :) https://m.dpreview.com/articles/8924544559/you-probably-don-t-know-what-iso-means-and-that-s-a-problem it is the amount of light per unit area on the sensor. It is ...

Yes, and as I have tried to explain: if you use the same exposure you will not get more noise at ISO12800 than at ISO640. If you don’t get it this time, then I’m afraid my pedagogical skills are ...

If you set your camera to ISO12800 and use autoexposure you will have more than three stops less exposure than if you set it to ISO640. There is more noise because you used a lower exposure, not ...

try to take images with the same exposure at different ISOs and adjust the ISO to the same when you develop the image I did that about 10 years ago with the a900: https://jar.smugmug.com/Photograph ...

ETTR is about maximizing exposure. The name is unfortunate because the histogram does not reflect exposure alone and can also be shifted to the right by upping the ISO for example. However, upping ...

That does not sound diffraction-unlimited. Btw, Canon an Nikon both have diffractive optics in their lens catalogs

The range the sensor can capture drops by one stop every time you raise the ISO one stop above ISO640 to maximize DR shoot at low ISOs. To maximize the SNR use the highest exposure possible. This ...
