A relevant question, one I was recently asked, is: how does the Canon EOS R6 Mark II compare to the Canon EOS R5, shown to the right of the R6 II in this post's image?
The R6 II vs. R5 specification comparison and visual comparison tell much of the story, but here are the differences between the Canon EOS R6 Mark II and the R5:
The R6 II advantages over the R5:
The R5 advantages over the R6 II:
The higher resolution imaging sensor is the R5's primary advantage from my perspective, and this camera remains my first choice. If 24.2 MP is acceptable for your needs, the R6 II is likely your best choice.
As always, let me know if I missed a differentiator.
Resolution test results from the Sony FE 135mm F1.8 GM Lens are now available on the Sony Alpha 9 III page.
While these results appear normal for a 24 MP imaging sensor (compared to the a9 II), normal is remarkable in light of the global shutter upgrade. Here are more comparisons:

The Sony Alpha 9 III is here, and it is time to set up this camera. This powerhouse of a camera may seem daunting to set up, but the process is not burdensome and not unlike other recent high-end Sony Alpha cameras. The following steps prepare a factory-initialized a9 III for use.
I make additional menu and other setting changes based on current shooting scenarios, but this list covers my initial camera setup process.
To copy this configuration means you intend to shoot as I do, including in RAW-only format. While this setup works optimally for me, you should adjust the camera to your needs.
If you can't remember your menu setup parameters, keeping an up-to-date list such as this one is a great idea. Anytime the camera is set to the factory state, such as when serviced or when acquiring an additional camera, the list will ensure all settings are quickly re-established. Better still, save the camera settings to a memory card (Setup > 2: Reset/Save Settings menu: Save/Load Settings: Save) for an easy restore or replication. The setup file can be copied to a computer drive for long-term storage.

One of the decision factors between the RF 24-105mm F2.8 L IS USM Z and the RF 24-105mm F4 L IS USM is the strength of the background blur they can create. So, I wanted to illustrate that difference.
Head over to the just updated RF 24-105mm F2.8 L IS USM Z review to see the background blur difference between 105mm f/2.8 and f/4 created using the f/2.8 lens. View both the full-size reduced and 100% crop image comparisons.
The answer is yes.

Note that 1485mm is the longest focal length I have enough working distance and a small enough chart to test. Thus, the 2x results were captured a bit short of the lens's capability.
I'll share the wide-open aperture comparisons. Consider also comparing the lenses at the shared widest aperture.
