I think they actualy do. I do not belive that the forum or even youtubers opinions are what realy shapes the professional workflow.
If you ask an actual profesional wedding photographer he wont tell you, that "this camera cant be used because the dynamic range is incredible low". They will talk about lenses, ergonomics, skintones, reliability and ease of use.
If you ask a film production company they wont tell you, that mirrorless small bodies are there first choice for filmproduction. They will stick to their Cinema-cameras because of the ergonomics, dynamic range, ports, accessories.
If you ask an actual professional sports photographer he wont tell you that 20 megapixel on his new sports camera is not enough. He will be happy with quick transfer rates and a reliable camera with an big viewfinder and fast AF.
If you ask a product- and general-photographer he will tell you that 45 megapixel is a great sweet spot betweeen noise an resolution.
I think the (often hateful and toxic) postings in forums are very often from people who are FAR away from actualy buying these kind of cameras. People get their opinions from youtube influencers who mostly dont even have the camera(!). Mostly these are paid commercials and they try to find a big topic. Most of these people dont actualy work and shoot every day with this camera.
I have the R5 since release and I used it (professionaly) nearly every single day since than for photo and video work.
I can tell you, its an excellent camera. Most things are perfect. What I diskile:
- Micro HDMI sucks.
- I miss a mode dial on the left shoulder, that power switch is a waste of space.
- Overheat before recording is a bit anoying, but can be fixed with an atomos.
- Viewfinder could be bigger.
- Micro HDMI sucks.
- Some functions disable other functions - if this happens you cant quickly overwrite the problematic function but you have to dive back to the menu and find the function and THAN go back - for example if you use silent shutter you cant activate anti-flicker. You have to first go back to the shutter and change it to mechanical and than go back to activate anti-flicker.
- USB-C Charging is not working while camera is on and wont work on most power outlets (weird, looks like it needs a very specific voltage?)
- Micro HDMI sucks
These are things that are not discussed in most discussions or youtube "reviews"(commercials). These are things that actualy matter in the everyday work.
Other than that its a pretty much perfect camera. Colors, AF, ergonomics are excelent and a joy to use.
