Sony A7R5 for landscape photography: a technical review

I have written an in-depth (4,000+ words) review of the A7R5. Unlike others, it doesn't attempt to go into all aspects of the camera, but instead...

In the review cited is an interesting reference to the 6.3 stops IBIs limitation if the Earth’s rotation is not taken into account.

Earth’s Rotation Limits IBIS Performance to 6.3 Stops

In 2016, Olympus Camera made some buzz in the photo world when they claimed that their new camera was capable of an impressive 6.5 stops of stabilization and that the limiting factor was in fact th…

To me very interesting discussion, including the comments at the end.
There is also this reference

Interview with E-M1X developer Hisashi Takeuchi – 43 Rumors

to an interview with an Olympus IBIS manager, giving clues to which approach Olympus has taken to get beyond the 6.3 stops limitation if the Earth’s rotation is not taken into account.

BTW if for safety reasons someone else drives you around with a car in a tight curve and you observe the level shown on a camera LCD or EVF you will detect how far the level displayed is off the actual level. I guess camera accelerators and gyroscopes at work. :)

DxO PL6 and PR3 offer these options for Denoising, namely:

• High Quality - also does Lens distortion correction
• PRIME - also does Lens distortion correction
• DeepPRIME - also does Lens distortion correction, Global lens sharpening
• DeepPRIME XD - also does Lens distortion correction, Global lens sharpening

I have used the last 2.
Unfortunately the last option delivers inconsistent results for high ISO images in my experience.
So for those high ISO images I use DeepPRIME.

For this image

DeepPRIME XD seemed to work fine.

For this next image

DeepPRIME XD seemed to keep quite a bit of noise especially in OOF areas of the image.

Clicking once, then double clicking on an image should show full resolution.
