Thanks! I updated to Resolve Studio (so now I officially have a reason to learn Resolve, LOL). Free resolve wouldn't load the 265 clips, but studio DOES. They look correct now. Don't know what's up with Adobe, and why only some clips show the strange behavior, and only on the upper part of the frame! I can at least use resolve to transcode the camera files to ProRes or cineform to edit in Premiere.

Holy cow- canon is rumored to have autofocus tilt-shift lenses in the works: https://www.canonrumors.com/well-we...campaign=Feed:+canonrumors/rss+(Canon+Rumors)

Yeah I dont see myself actually buying an AF tilt-shift but the technological development is impressive.
The only thing about the f/1.2 lenses is that autofocus seems to suffer from the weight and complexity, though I'm not absolutely certain.
But Sigma makes a 35 f/1.2 for E mount that I investigated - gorgeous rendering. But apparently in video autofocus you can see the lens stepping through the focus range at discreet intervals. Maybe the canon will do better?
A lot of the f/1.8 lenses seem super speedy in autofocus. The sony 85 1.8 is apparently the fastest 85 of all.
Then you've got the tamron 70-180 f/2.8 which is supposed to be one of the fastest telephoto zooms for e mount for autofocus. Sigma was supposed to release their 70-200 earlier this year but then they delayed it to work more on the focus algorithm. My guess is that they realized the tamron would run circles around their heavy OS 70-200.
Autofocus complicates lens evaluations, that's for sure...

The relatively cheap(affordable) Canon EF 85/1.8's AF is pretty darn speedy. Especially compared to the glacial 85/1.2.
The RF mount 85mm f/1.2 is considerably faster in terms of autofocus speed than the EF 85mm f/1.2 version. There's a brief comparison in this video: https://youtu.be/Qdt7uAyGCJw?t=324
Among Canon's newer lenses, the ones that seem to autofocus fastest and have the smoothest transitions for video are the ones that use Canon's Nano USM autofocus motors: https://www.usa.canon.com/internet/...gy/Nano-USM-A-New-Ultrasonic-Motor-Technology
The RF 24-70mm f/2.8, 70-200 f/2.8, and 24-105 f/4 all use Nano USM motors.
I think that given the small size of these motors, however, they may not be powerful enough to move the larger glass elements in some of the large aperture lenses. So these lenses tend to use larger ring-type USM motors instead, which are a bit slower to autofocus. Ring type USM autofocus motors are used in the RF 50mm f/1.2 and 85mm f/1.2 primes and the RF 28-70mm f/2.0 zoom.

People are doing mods to improve the 8K recording time of the R5. Not for the faint hearted as that will invalidate your warranty https://petapixel.com/2020/10/12/th...5-thermal-mod-enables-unlimited-8k-recording/
This is interesting, but the unlimited record times were done at cooler than normal (15C / 59F) ambient temperatures, and it seems like you still need an external fan pointed at the camera to enable extended 8K recording times in more typical ambient room temperatures of 25C (77F).
So it's not clear that this is much of an improvement over earlier tests of the updated R5 firmware with an external fan (and without any internal camera mods) that allowed for 8K recording up to 90 minutes or more at room temperature: https://www.jodumedia.com/blog/eos-r5-with-firmware-11-is-now-a-video-beast
And it seems like the internal mods would end up sending more heat through the power board on the camera, which may or may not be ideal and could in theory shorten the lifespan of that component (power related components are already among the least reliable parts of a lot of electronic devices). So I'm not whether this is worth the risk for a relatively modest improvement in recording time.
If anything, this kind of reinforces the notion that truly unlimited 8K recording in any environment would require a complete thermal redesign of the camera internals, with the addition of active cooling, or a sizeable heat sink, or perhaps both.

Curious if anyone is even interested in having an autofocus till shift lens. I use my tilt shift for table top and architecture photography which both are really shot at high depth of fields. pretty much always doing manual focus and after she didn't video for those subjects the camera movements are generally on the slower end or motion control.
That said I'm very interested to see how the technology works in it as it's cool for sure I just don't see it being worth the extra cost for me personally
That said you till shift lenses is intriguing for sure as I'm hoping it's some nice new sharper glass. kind of makes me debate on if I want to stay with Sony as I'm really loving the RF glass. It costs the switch brands that I just seems that way the benefits from a business perspective for me.

My feeling is that Canon has fundamentally better products and a brighter future than Sony......I say right after buying a Samyang 85 FE on Amazon
Maybe Sony will catch up. Maybe the difference doesn't matter. I leave open the possibility to return to canon. Maybe a used C300mk3 one day and a fully functional R5mk2
I see a lot of wedding photographers use tilt-shifts to isolate the couple in a group by blurring everything but the center. AF would be great for them. Mostly I think it's just a cool development

That's how they want you to think about purchases. Welcome to the cabal, my friend...

The FS7 and A7SIII will probably be good enough for my needs for years. If I need something more or something specific for a shoot, I can rent it. If I have an important client who 2wants a specific camera, I can buy it. The form factor, battery life, lens selection, functionality, codecs, frame rates, resolutions, sensitivity, dynamic range etc on every 10-bit 4k60p (no-crop) canon and sony camera out there right now is so good that further marginal increases may go to waste for most of what I shoot. It'd be nice if the FS7 had hybrid AF but oh well, I've gotten by without it this far and the A7SIII is my gimbal camera anyway

I guess this is relevant here too.

Wow. The R1 could be the motherlode. Global shutter? It also says it will have the fastest fps of a stills camera. I wonder if you'll be able to record constant 24p with the same files or a modified codec of the still photos.
The new AF system could be quad pixel AF that supposedly handles contrast edges in the direction perpendicular to the edges it can currently detect.
"Here are a few things I have been told by a good source, keep in mind that this far out from a product announcement, things can change.
An all-new image sensor with a global shutter
A “groundbreaking” new AF system, above the EOS R5/EOS R6
The fastest framerate for a stills camera ever from Canon
The second half of 2021 announcement"

This is very interesting, but mostly because it tells me that it's basically imposible to focus manually at these resolutions. At 6:21 the R5 seems sharper than the UMP-12k, but that's because the R5 is focusing on her eyes, whereas the UMP-12k is focusing on the earrings. You could just not care because when downsampled to 1080p both will look well focused, but if that's the case why even bother shooting at such high resolutions?

OT but a ridiculous deal for a relatively nice EF/F zoom (with VC IS) in the DZ until midnight:
