It's far from new, but getting the performance to a satisfactory level is still something VR is struggling with. It's one of the few areas where hardware still makes a big difference. I'm just wondering how anyone will be able to play it back. Stuttering is not acceptable in VR, and I doubt there are many systems able to play back 8k60p with high refresh rate headtracking properly. However, with the de-fisheying of the VR lens, I guess it's not necessary to have the final delivery in 8k even though the initial recording is. A significant portion of the original recording is black anyway. Perhaps recording in 8k60p and delivering in 4k60p or 6k60p would be better.

Rendered VR obviously has a lot more potential since it can be interactive, but one advantage of VR-video is the turn-around time. It should be possible to produce something decent in 1-2 days with VR-video, while rendered projects can get very expensive as soon as it's anything more than a walk-through of an existing 3D model or a 3D-scan. Good points. There are so many things that can give you motion sickness in VR and I don't think we fully understand all of it yet, and at least don't have the solutions for all the problems. The more problems we are able to solve, the more we'll be able to do in VR before we get motion sickness. I've done a couple of VR/3D projects with just 2 regular cameras (2xGH5 or 2xGoPro) and the editing process was a nauseating experience. A small alignment mistake in Premiere and I ended up feeling sick for the next 3 hours. My hope is that this Canon lens will make that a rarer occurrence...

I don't think there is any removable frame. You simply cut out a piece of ND gel and slide it in. There is a small track to stop it from falling out, and since the exit pupils are rather small, the gel will cover them even if your cutting is not very accurate. The solution is a bit crude, but I don't see why it wouldn't work as long as you've got high quality gels. That was definitely one of the first adopters, but VR has grown quite a lot in the real estate industry. I've got clients using it for visualizing unbuilt homes and for visualizing outdoor city-scapes. Admittedly, most of this is based on renderings. VR videos are mostly used for placing new objects into the scene as a substitute for AR. One of my clients has even got a large 3D 180 CAVE so that you can use cinema style 3D glasses instead of VR glasses. I haven't figured out how to run VR videos on it yet though. So far it's only for renders.

I've got the lens, but just received it last week so haven't had time to edit anything from it yet. A few notes: - the lens is much smaller than I first thought it would be. I take this as a plus as it's very easy to bring with me. - the R5 firmware actually has quite a lot of features specifically for this lens. You get the framing for each eye, and instead of a box, it's rounded, accounting for the fisheyedness. When you zoom in you'll zoom in on a single eye and use the "Info" button to switch between the eyes. The eyes are also labeled "R" and "L" on the screen, with R being to the left and L to the right because of how lenses flips everything. - the manual focus is smooth and seems quite easy to work with with the manual focus assist. Some zooming in to make sure it hits is of course still useful - because of the bulging front elements, it feels like it's very easy to scratch the lens. I never use lens caps for my lenses (just permanent lens hoods), but with this lens I am hesitant to let anyone else touch it without the lens cap on as I feel it's a gamble if it will be handed back to me without fingerprints on the lens. If anyone has any specific questions/things I should test with it, feel free to let me know

If they wanted to do the test a bit more seriously, they should have at least tried to find lenses with the same design for the different formats. Finding a Double-Gauss design lens with a similar angle of view for all formats shouldn't be too hard.

I should preface this by saying that most of my experience with medium and large format cameras are from analog cameras. I don't own any medium format digital cameras, but I've got 4 medium format analog cameras and 2 large format. More surface area makes it easier to put in more/better electronics than on a smaller surface area. If it can be explained it isn't magical? Lenses are perhaps even more important than the sensor, and adapting a lens to a smaller format than it's intended to will cripple its potential. This combined with the point above is the advange of larger formats. I guess this discussion is the one I dislike the most. The light gathering mostly comes from the lens. My fastest 6x9 lens is a Schneider-Kreuznach Xenar 105mm 3.5. My Canon f/1.2 lenses gathers more light on a full frame sensor than any of my 6x9 lenses. However, I don't really care as both of them gathers enough light for my uses. My Kodak Ektar 152mm f/4.5 might challenge my Canon glass... if I only had a digital back for it. And now to the admission that you might be right. Every time I've taken photos with my GH5, I've been disappointed with the look. It's hard to explain why, but the photos simply looks boring compared with my full-frame photos. It's almost like the magic is missing. Maybe my full-frame cameras would feel the same if I owned a medium format digital.

I find sensor format discussion to be the least fruitfull discussion in the video/photo community. But I'll join it anyway with my opinion: - There isn't anything magical about any certain sensor sizes - "Full-frame" is the best choice in most situation simply because it's the most adopted format with a large selection og good lens and up-to-date image sensor and focusing technology - I enjoy shooting 6x9 and 4x5, but 4x5 is too impractical for everyday use

I got to try the R5c at a Canon event just now. The camera was much bigger than my impressions from the videos. It also seems like the camera reboots completely when you switch between photo and video mode. This makes the switch take longer than on the R5, but you get completely new interface with shutter angle and so on. I am also pleased so see that it can handle 4 audio channels. My impression is that this is not a hybrid camera, but a cinema camera.

I stand corrected. Looking at the DXOMark graph, it seems like the dual gain is at 100/400 ISO. Good to know!

Any source on that one? The R5 does not have dual ISO, and they use the same sensor.

The R5c is a perfect match to the 5.2mm VR lens, especially since this lens doesn't support IBIS. I've got the 5.2mm on preorder since it was released, and is one of the reasons why I was looking forward to this announcement. However, with the current shortcomings, I would want to find out how the the 5.2 mm lens works on my R5 before making any more decisions.

It's been confirmed that it has micro-HDMI and no IBIS (see video below). I shoot more photos than video, and therefore it's not a good replacement for my R5. Even though it makes sense to remove IBIS for heat management, it means it cannot replace my R5 and I won't pre-order it. For the second point, the micro-HDMI is currently broken on my R5, which just demonstrates what an odd (read bad) decision it was to not go for full-sized HDMI on the R5c. Source:

Shutting down a factory isn't necessarily a bad sign for Canon. The camera market is obviously a shrinking market, and to make money in a shrinking market it's necessary to downsize long before you have to downsize from a financial perspective. It makes perfect sense for Canon to cut back on the manufacturing capabilities for lower end cameras and focus on the high end units. I would have worried more if Canon didn't close factories.

A bit of a thread resurrection, but I don't mind. I'm actually doing these lessons these days as well. I learned Premiere by trying and failing and really wish Adobe provided something similar back then. It's easy to miss some key feature when learning a tool by oneself.

I would guess that they either powered both the camera and a monitor with the same power source or that they had a faulty power source that gave the wrong voltage. Using an NP-F battery connected to a dummy battery shouldn't be able to fry a camera since it's the exact same chemistry as the cameras own battery, just removed from the body. That said, I would have been a bit sceptical of letting other people use dummy batteries with my cameras. I've seen 12v connectors which are suspiciously similar to the connector for my 7.4v dummy battery. When I use dummy batteries I want to be 100% sure of what I'm feeding my camear.
