fathergll Yes, this scene is severely out of focus, the production team should have done a proper check before shooting. Also, the aperture you chose also plays a big part, if they shot this at f2.8 I can see how they could more easily screw up the focus. I personally calibrate my focus on my r5c before each shoot. I printed large 2'x3' focus card sheets. F5.6 is the sweet spot for this lens but you will need more light indoors, I only shoot at f2.8 indoors when I know all of my action will stay relatively compact. Also, since the focus ring is so accessible it could have just as likely been someone accidently bumping the focus ring while they were rigging or adjusting something else haha, that has happened to me also.
There is no way around the difference in IPD between the 2 cameras. Regarding the scale difference, the best solution I have seen to match the scale difference is to zoom in each lens of the r5c in, it does zoom in and artificially increase the IPD of the footage, it also leaves a little bit of warp on the far edges, but the scaling is essentially matched to the k2 pro footage. Not an ideal solution but it is possible.
And yes, you are absolutely right, there are studios who are putting out perfectly good content with this camera, just like the other scene you shared in one of your previous posts.
Regarding noise, yes it does have noise, specially when you shoot at its base ISO of 800. The problem I have discovered in all my testing is that you should not shoot at iso 800 for VR in the first place. Yes, base ISO will give you the best dynamic range, but this mentality comes from mainly the non vr filming standards. Noise suppression is far more important in VR than a little more dynamic range. There are plenty of other manual ways to control the lighting of your scene than to rely on dynamic range from its base ISO. I personally use 100, 200, or maybe even 400 ISO when I shoot and the noise levels are good enough at 400 and almost non-existing at 100-200. I also have been using the canon VR utility to convert to equirectangular and their tool has a build in noise reduction dial, which cleans things up even more. I have not needed to do any noise reduction using those 2 methods. yes, you might need to use a little more light and you lose out on some dynamic range, but who cares, I'm not going to purposely film in super contrast scenes in the first place. I really think that was also part of the noise issue some people were complaining about. Some studios stuck to the traditional way of thinking to only shoot at base ISO levels and found out that trying to apply noise reduction in post on a 8k video will take ages haha and said screw it, its good enough.
