Ha.. Yes, I think it is a pretty amazing camera. To put it in perspective, even those reviewers that are notorious for being anti-Canon are very enthusiastic about the R5/R6. It is a stills first camera, so if video is your thing, either wait for a firmware update (looking more and more like that the heat issue is mostly firmware related and not a physical issue. I.e. either Canon is being ultra conservative with their temperature thresholds or they intentionally limited the R5/R6 so they would not compete with the Cini line). But, if you mostly want a stills camera...here you go. If you do not need the 45 MP, try to R6, which in many tests is coming close to resolving the same detail as my 30 MP 5DIV.

Two impressive cameras. Impressive enough, I am seeing several people shifting to them as their main cameras, including TDP's Bryan.

So, I have saturated myself to the point where I feel I have an reasonable understanding of the Cameras, even though I have not used them myself. Ultimately, they are tools, granted, industry leading tools. Where they might be limited a bit compared to other tools out there (for stills):
  • FPS: Apparently the 12 FPS is with fully charged battery. As the battery diminishes, so does the FPS. This could be a decisive advantage for the 1DXIII for those that want fast FPS. As of now, I am mostly viewing them as a ~10 FPS cameras. Which is still amazing, especially for a "event" camera, but is that enough for me to upgrade my 5DIV? (short answer, FPS probably not, but increased buffer, yes)
  • Battery: Two issues here really:
    • While I am pleased to see multiple people reporting getting >1,000 images per charge, ultimately the CIPA rating is still low and there are likely times when the CIPA rating will come true. Also, the 1DXIII CIPA rating is crazy high. So, if buying these cameras, plan on having a couple of fully charged back up batteries. Not end of world issues here, but it will have an impact.
    • Volts. The 1DXIII (10.8V) still has a volt advantage compared to the LP-6NH (7.2 V). No reason to thing the R5/6 will be any slower in moving glass to focus, but the 1D line still has an advantage.

  • AF. While Eye AF is getting lots of hype and seems to have the potential to alter how we photograph a scene similar to auto exposure modes, I have been let down a bit by other AF modes on my M6II. I am waiting to either try the new "DPAF V2" out myself, or see if others run into the issue, but I bought my M6II in part to "test" the latest MILC technology. Overall, I am very impressed, it is a great little camera. But...there are issues. In particular, the M6 II, which has DPAF v1, seems to have some issue focusing on smaller points that my 5DIV is capable of. I have not perfectly isolated this, but I do wonder if the individual sensors of the PDAF are physically smaller than the area needed with DPAF (at least V1). This is a theory, and I may be off, but once in awhile I run into an issue where the M6II just has problems focusing and there seems to be a trend where it is when what I want to focus on is small. I.e. a bison that is very far away, or hummingbird's eye. But, give the M6II a larger target, and it does great. Even a slightly larger birds eye.
  • EVF. It seems that Canon is crossing the line where the advantages of an EVF may outweigh those of an OVF. But, that will come down to personal preference. It took me over a month to really feel comfortable with the EVF on the M6 II.


But, even in the ways that many reviewers said Sony/Nikon were better than Canon, the R5/6 are now as good or better. Everything I see tells me that they are class leading cameras and that Canon really nailed it. You are going to have to get specific when looking for a "better" camera. The 1DXIII is likely to have advantages, not everyone will be able to afford a R5, etc.
