Originally posted by Winder I think you are misunderstanding something. I have not owned a Canon since I sold the 5D. I have shot with a lot of them. I have shot thousands of frames with a 5DIII and a 1DIV. When I was shooting a significant number of wedding I worked with several photographers who would either shoot as my second or I would shoot as theirs. I would use their Canon gear so that when they went to edit they didn't have to deal with different RAW files and different color profiles.
If you like Canon, shoot with Canon. Canon has great pro-support, great lenses, great marketing, great distribution, but their cameras are average at best.
The EOS-RP is going to be another average camera with dated technology. Hopefully they will release a upper-end model with more advanced technology. The more competition in the market the better.
I would really love to see some files from A9 and 5D Mark IV from you where the A9 files are much better. Again, I'm not a fan of DXO charts, but the dynamic range from 5D Mark IV is rated better than A9. In practice, there is no difference in recovering shadows. Yes, the A9
has a better af-c, but as all other cameras from all manufacturers will miss focus from time to time in restaurants with dim light, even with the famous eye af. Maybe with the upcoming update they will make A9 af perfect. And yes, A9 also
has a little better high ISO than 5D Mark IV. But, if you resize the 5D Mark IV from 30mp to 24mp to match the A9 files, the noise will be similar.
Here is a print screen with 2 zoomed images
taken with A9. It's my father in law in the images, dancind with his wife. He knew he is being photographed so he didn't moved too much. These are 2 images from a series of 3 consecutives images. If you look at both images, you will see that on the left image the focus is on the nose, not on the eye like it is on the right. And I have quite a few similar images from that event where A9 missed focus. Yes, my 5D also misses focus from time to time, but it's far from being "average at best" to quote you.
