Canon EOS R6 buffer depth issue

I believe Canon are only putting a number up there that they can be fairly certain of. They nlknow their algorithms and hardware, so they can calculate the number based on the internal memory and average file size expected for a given recording type. The cards they'd have to benchmark each time they are inserted. They certainly could do that, but I think with how conservative they are, they don't want to get blamed if card manufacturers pull some tricks like having a separate buffer on the card.
Makes sense, that's what I was thinking. This number is more like an "worst case scenario" indicator.
Thank you guys!

R5 always on?

I believe that the lens always has power. People complained about the IS of the EOS R being always powered even if the camera was off. I expect the R5 is similar.
After the last posting about this, I listened to the IS of my 100-400mm II on the R5 and it stopped whirring a few seconds after I stopped half pressing the AF button. The IS is turned off when the power is off.

Dream Lens List

I don't have a dream lens list. The lenses I have cover about every circumstance that I am likely to face, other than those best taken with tilt-shift lenses. If I know those occasions are coming up, I can always rent one of those lenses. Earlier in the pandemic times I rented the 24mm for ten days and a month later the 17mm for a couple weeks. They were fun to experiment with, and now I have a better sense of how and when to use them. I concluded that I wouldn't use one often enough to splurge on owning one. I guess if I had a lot more money, I would buy the 24mm to sit on the shelf until some use came to mind.

As it is, I have excellent L zooms on the wide and telephoto ends, a kit 24–105mm for the middle, and several prime lenses for special use, including the 100mm non-L macro. I don't shoot things that some of you guys do, so I don't have need to cover those situations. While I enjoy the aesthetics of owning nice glass, photography is still more my hobby than is buying photography equipment. I do have occasional bouts of GAS. Last week I was pricing star tracker drives. The reality is that I have an 8" telescope that I haven't taken out of its trunk since I've lived here. It was fun back when I lived out in the country and had dark skies. The old clock drive on it is probably not too accurate any more, and the tilt angle is sort of a coarse adjustment. But I still got some decent shots of Jupiter and the moon in film days. If I lived in a less light-polluted place, I'd be tempted to get new gear for that. I haven't even tried to see whether my old Canon telescope adaptor will work on current cameras. The mounts seem similar enough that it might.

When Halley's comet was coming around these parts, I lived in the middle of nowhere between dairy farms. I would take my binoculars out each night and see it, but also look at other things. The Pleiades were spectacular through them, like hundreds of little jewels. I looked at Jupiter one night and saw three little dots near it. I was skeptical, but I looked at a chart in an astronomy magazine, and yes, three of the Galilean moons lined up as I saw them, and the fourth was obscured by the planet. Jupiter is very bright right now and conveniently in the south at decent hours. I took out the binoculars and looked at it. I don't think I am very shaky for an old guy, but I could not hold them still enough to get a good view.

So maybe my next equipment decision is what if anything to do about astronomy, viewing or photographing. Maybe I already decided not to bother.
Maybe move back to a dark sky location? :D

Eye AF struggles in bright sunlight

Interesting. I thought that the shape and position of the eye within the shape of the face was more involved. So does the camera lose track completely of head movements while eyes are closed? Does the Eye AF snap back right away when the eyes are open again? I wonder if different makeup applications have an effect? Did you try with different lenses?

I'm also curious about how the EVF is in bright daylight. I was using the Hoodman Eyecup for my dSLRs for years. The R does not have any straightforward, aftermarket kind of eyecup that fits, so I often struggle in slanting morning and afternoon sunlight. In fact it can be a major PITA! (Or, more precisely, a major PITE(ye). )
I'm assuming that one of the things the camera looks for is a round shape and if you're squinting, it confuses the camera. One blogger tried making crude sketches of a duck's head and the camera locked onto the eye in the drawing. The camera will instantly react to an eye being exposed and if the model moves her head, it will jump to the other eye. If it can't find an eye, the camera will typically focus on the head. The big thing for me is understanding how the camera reacts in certain circumstances so I can anticipate its reaction.

I haven't had much of a chance to try the eye focus with my 100-500mm yet.

The EVF gets washed out by sunlight and I have the EVF brightness setting on my custom menu so I can jack it up easily. It is set normally at 3 and I move it to 4 for bright sunlight. I want to get an eye cup for mine as I think that will help. I don't wear glasses when shooting but it's still hard to block out the light that comes in from around your head.

Here is the Canon Cinema EOS C70

No offense, but that typo is really fitting for all your vaporware products :ROFLMAO:

I respect the passion you demonstrate with your posts, but I don't think you can blame people for arguing with your spotless record of predictions and products we'll see eventually :)

I finally decided the best thing to do with a phony liar like him is put him on ignore.

Venus Laowa Zero-D Cine lenses for RF

Venus Laowa is is making their Zero-D Cine lenses available for RF mount..

Interview: Canon addresses overheating concerns, workarounds and the Cripple Hammer

But vocal groups on the internet are not 'the market'. What backlash is there in the market? As far as I'm aware the pre-orders are still not all fulfilled from people who ordered on the first day. The demand is huge, and once the dust settles, I suspect the R5 will be a milestone for Canon. The outcry seems louder and greater, because so many people are interested in this camera this time and therefore the absolute number of disappointed people is greater too.

I would suspect Canon to go all out in the neir future. It started with the M6 II, and the R6 and especially R5 are just taking the technology that was hinted there to their logical conclusion. In hindsight, the 1DX III is pretty conservative still, but that is also what one would expect from the 1-series. The R5S/R3, R1 and potentiall R7 will likely push the boundaries even further.
Ooh I do agree with you. I really hope that Canon doesn't go back into their "comfort zone", the R5 has been more than everything I've been looking for. All I wanted was full-frame 4K60 (for b-roll) and possibly 10-bit interal (as hinted by the 1Dxiii). What I have now is a very useful tool for 4K23:98 and 4K120 (for b-roll) all in 10-bit recorded internally. I've never overheated or recieved a temp. warning since take delivery 7/30.

The only thing that would make me possibly replace my R5 would be a fullframe version of the C70 only because of DGO. (I was looking at old Arri Alexas prior to deciding on an R5; the prices aren't that much far apart now.)

C70 Speedbooster for EF glass. Does this mean RF glass has smaller image circle? How does this all work?

Do you also believe in perpetual motion? Lenses curve different colors of light different amounts. You add more elements to try and neutralize it, at least in the center. Each lens is ground imperfectly and the glass has flaws too. You keep adding them, usually 5 or 7 elements to the point where there are diminishing returns. It will never produce a better image than the bare lens.
Again, it depends on what you are comparing and I explained the specific case where adding this adapter will lead to sharper results with potentially slightly less chromatic aberrations than without it. Will the flare become worse with the extra elements? Will the bokeh rendering change? Possible.
There are quite a few comparisons regarding the Metabones Speed Booster which you can look up if you want.
With the Canon adapter there are no side-by-side examples as of yet, but on the first look video, it looks to be even a bit better than the Metabones (maybe because it is even more optmised for the Canon sensor size)
