Lensrental R5 heat emission investigation

I will take that bet, the grip gets warm shooting bursts. Nothing crazy but I sure do feel it more on my R5 then my R and RP. The CFexpress card, Processor and VRAM are all in the grip and it adds up quick to be a warm camera.
Ha...sounds like you have one in hand. How warm would you say it gets compared to ~20 min of 8k video?

Eos R6, or wait for the Eos R Mk2

Joules - I'm aware of the budget FF announcement, but I feel that's a little too much in the other direction price, and likely feature-wise. As for the alternative upgrade options you suggested, I feel like they all have their limitations, except maybe the 90D... Alongside the things you mention, the 5d4 has a gimped rear screen (no touch, no swivel), the R reviews I'm reading say that it detaches from the SLR user experience when it comes to controls.

Czardoom - I'll miss the extended reach for now, especially as I'll only have the 24-105 to start out with, but I do like night, and have been very limited by not being able to get many keepers above ISO 400. I also like to shoot sunsets, so the extra shadow detail would be useful.

It try not to crop too much, as I like to try and get the composition right in camera. However, cropping would be useful when shooting moving subjects.

I'm not considering the M6 due to it's size and tiny grip. I actually find my Rebel a little small for long shooting sessions, as my pinky hangs off the bottom, and ends up cramping because I'm squeezing my hand.

How do you find the EOS R user experience?

Teardown: Canon EOS R5 by Lensrentals.com

Yes, it would make a fun project. But what would interest me is if they came out with a astronomy specific version of the camera (R5 or R6) - with different sensor filter and an add-on ability (by Canon or others) for a Peltier cooler through the tripod socket or additional bottom electrical interface, with 120/240V wall cord, or else DC cables to a big car or lithium battery(s).
IBIS would need to be removed to enable any cooling of the sensor itself and I guess a heatpipe directly connected to the back of it to conduct heat somewhere external. The heat spreader to the tripod is at the back of the circuit boards if I follow Brian's teardown correctly. It isn't connected to the front spreader which is closest to the sensor, processors and card slots.
Using the R mount drop in adaptor with specific spectrum filters would be an interesting touch.

Uncle Rog's Teardown of the R5

" So we have the regular overhang and foam sealing on top that gives rain protection, but the bottom, the part you might set in a puddle, is tightly sealed. It makes sense unless we missed a leaking point on the bottom. "

At least my impression is that the lower 2/3rds has something new and better, the top 1/3 has the same weather sealing as previous "5" cameras. Overall, I consider this very good. But, yes, I can see how carrying the camera upside down in the rain might be an issue. You'd be counting on the foam sealing.

Patent: Canon RF 14-21mm f/1.4L, yes…. f/1.4

Which companies have delivered a...

A) 11-24mm f/4 zoom lens
B) 17mm f/4 tilt shift lens
C) 8-15mm f/4 fisheye zoom lens
D) 24-70mm f/2 zoom lens

On the way, could you also check how often do other companies' patents actually come out, and after how long? IIRC, it took Nikon ~7 years to come out with an ultra wide perspective control lens, and it isn't as wide as Canon's.
I totally agree, the days of not so great wide lenses from Canon is a mantra from over 10 years ago and completely dispelled from the launch of the TS-e 17mm onwards. Going back the the EF lens history...Just to add to your innovation list here....Canon were in fact the first manufacturer to deliver a constant aperture 28-70 f2.8 (1993) then later a 24-70 f2.8 (2002 - pre digital). They also produced the first 80-200 f2.8 aka the magic drain pipe in 1989. it was the first constant f2.8 design. The more familiar 70-200 f2.8 (1995) and a 70-200 f2.8 LIS (2001). Both the original 24-70 f2.8 L and 70-200 f2.8 L were so revolutionary and so far ahead of the competition it look a long time for anyone else to even come close. When Nikon finally made their fantastic 24-70 f2.8 variant...it was a total rip off of Canon's novel design, although newer and sharper..but some 10 years later...what does one expect? In fact these two Canon lenses stayed in Canon's front line lens catalogue for a lot longer than any of the competition's...which point to how Canon innovates. They get it SO right...the first time.
The four lenses that you listed are still without equal. I personally own and regularly use a TSe 17mm and a 8-15mm fish and there is nothing vaguely simular from any other marque. Some of these lenses have been around for a long time now. My 8-15mm fish was bought from the first uk batch (and it cost me a lot). That was nearly 10 years ago. My TSe 17, I've owned for over 11 years.

For those moving from an R to the R6, thoughts?

I'm confused by this thread. Universally the freeze frame/stutter of the R was universally panned. But a lot of people jumping in here to say that the blackout that replaced it is worse? I'm trying to understand that and just can't since blackout is more akin to a DSLR experience.
I posted some months ago that the viewfinder stutter was the biggest issue I had with the R and how I couldn't believe/understand how RF lenses would help compared to EF lenses. Well I now replaced my EF 24-105/4L with the RF version. Switching on high speed display with the RF lens now makes a big difference and I no longer consider this a major issue with this lens/camera combo.

Laowa introduce ultra-wide angle 9mm/f5.6 for mirrorless FF

I assume the stepless aperture is for videographers, and the shift function is for architecture photographers. I do not presume to speak for either audiences, so I'll pass on any further comments.
This is what someone would assume if reading only the specs.
In practice it is different: the range of the aperture control is very small and difficult to adjust. The scale is also very small less then 4mm from f/11 to f/32.
The shift function could only be used with APS-C Cameras (mentioned in the manual). You could only shift vertical and only +/- 6mm. Nothing in between. No scale. No possibility to fix. The disadvantage of the additional moving parts and the possibility dust and humidity getting inside overweights the advantage.
With the Eos R i cannot use it at all, with my former 80d i tried to use the shift but the effect was always to strong.
the reviews you can read just as well as I do?
The reviews of the 15mm Laowa are good examples why i prefer the experience of owners:

"The shift is said to work best on APS-C. It can be used on 35mm frame, but there is likely to be vignetting. "

I tried it again yesterday and the shift turned a straight line into a S-shaped curve. The quoted statement is simply wrong.

Are 32 MP too many? EF-M 32 mm 1.4 on M6 II

If a person is asking the question, I'd go elsewhere because they don't know how MTF works. Every component in a photography system can be assigned a MTF. Even film had a MTF. The electronics processing a digital signal can have a MTF.

The final result is always lower than the MTF of the weakest link, be it the lens, sensor, Monitor, printer or whatever is part of the system The final MTF is equal to the product of the individual MTF values.

So, given a lens MTF of 0.8 and a sensor MTF of 0.7, the system MTF is 0.56. Without changing the lens, increasing the resolution of the sensor to say 0.8 will increase the system MTF to 0.64 all using the same lens. Improving the sensor always improves the system MTF as does improving the lens, but a lens does not out resolve a sensor, thats nonsense.
If you are refering to my click-baity title, it is just that. I have seen posts recently that had doubts about Canon's choice to put a 32 MP sensor in upcoming EF-M cameras. Of course more pixels will yield an improvement, but images are more convincing than words. And they also show the degree of improvement, which is dependend on the lens. So when I wanted to show how even a lowly EF-M prime can make great use of such a sensor, I discovered that TDP lens comparison tool doesn't feature the M6 II for the primes. So I thought this video was worth sharing for the skeptics, as it is the first such test I have seen with this lens and sensor.

If the M system isn't doomed, we may well see more such excellent performing lenses released to add further justification to using this high res sensor in upcoming models. Although that's just speculation on my part.

Canon 550EX [used] vs Yongnuo YN600EX-RT II [new]

If you can afford it, get a Godox V1. The round head makes beautiful light, and the flash can be charged via USB.
The accessory pack that you can buy has some very useful things in it that connect magnetically too.
Since getting one, I've basically stopped using my Canon flashes.
I've looked at buying one of those but haven't pulled the trigger yet. I bought a Flashpoint Zoom Li-on R2 TTL On-Camera Flash Speedlight (V860II-C) to use as a small flash and really like it. With the popout batteries, it's easy to replace batteries and keep shooting. I typically use my AD360 which is 360 watt-seconds and reminds me of the old days with my Metz 202 potato mashers. That's the one thing I dislike on the AD360 is that it is heavy. If they would pull the capacitors and put them in the battery pack like the Metz, it would be much easier to use.

Patent: Another stacked CMOS sensor patent

On the R5 vs 1d3 question, I can say the R5 is better. I had both with me last week. I think it was a discussion on this board, although it might have been on a different one: I couldn't make it do much in the way of rolling shutter in my efforts.

A site I contribute to has an R5 review like everyone else, and they did rolling shutter tests. A boy on a bike and a running dog looked fine, but the real test was a flying helicopter's rotors, and it looked great on the R5. You can see the picture of it if you go here... https://camnostic.com/r5-3/
... and scroll down to the "Major Capabilities..." section and click on the "Jello" tab. You'll see the rotors are pretty straight.

Until a month ago, I owned and shot the Sony A9II, and after a few thousand frames with the R5, I think they're about the same; which is to say, you don't think/worry about it while shooting them.

Which R* is the right one for me?

It seems you’re in a different boat to me, as your 7D love isn’t for the reach you can get with long lenses. Given that, an R or RP should be OK; you’re not going to miss the pixel density once you have to crop down as much.

If you’re already considering the RP, then maybe look at a cheap 6D II? It’s not mirrorless, but it’s still smaller and lighter than the 7D somehow, and the buttons are closer to where you’re used to.

Canon R5 or R6 with $5k budget

If you were planning to stay within the R series, why did you sell your lenses?
To give the option to look at all options but in the end I could not leave Canon. I had the RF 24-105 F4 and 35mm 1.8. Figured I would entertain 24-70 2.8 and/or 50mm 1.2 but in the end decided not to switch my lens setup. I did not know the lenses would be in short supply.

Lens upgrade advice.

How can there be no loss of image quality using an old EF lens on a high resolution Mirrorless camera such as the R5? Wouldn’t certain glass that’s soft on a DSLR be just if not more soft on the R5?
A lens won't be softer on a higher MP camera, indeed it will often be sharper. But you will gain more with a sharpwr lens on a high MP camera.
My EF 24-105/4L (v1) was noticeably sharper on my 5DsR than on my 6D. Indeed, it was sharper at f/8 than my EF 35/2IS at f/8 on the 6D.

Canon Australia to close their online store to support retailers

Maybe they can close the Canada store as well. No one ever buys there due toi the insane prices and the fact that they never do deals on useful stuff like they do in the US and UK. If they close the Canada store maybe we will finally be able to order from Canon US and get in on the deals. You have never been able to buy refurbed any thing in Canada for example. So when CR posts great deals on refurbed lenses for example the only effect it has is to piss me off because I know Canon will never allow Canadians to buy them. NAFTA never worked the way it was supposed to.
I’ve never seen Canon refurbished sales in the UK. Have I been missing out?

File Transfer Speed EOS R5 to Windows PC

Make sure that the USB cable you buy is certified for data access. Some cables are only designed to charge the device. Also, it's usually better to use shorter data cables rather than a ten-foot one.

On the topic of charging, if you want to charge using the camera and the camera & battery grip combo, you can buy a USB-C charger for $25 from Amazon that works instead of the $150 Canon one. You just have to make sure the battery charger has Power Delivery or PD capability and is of sufficient capacity. PD makes the charger smart and it figures out what the device requires for charging as there are a number of USB-C type charging requirements.
