R5 not showing Exposure Simulation with flash - solution found.

Set the button to change aspect ratio. That’s what I had it set on when I discovered this. don’t select anything. Simply press and re-press And it should work for you. Love it if someone could confirm it works for them too.
Thank you. Please see my comment in the other thread with this topic--and note that the R does not have a dedicated DoF button, but the instructions are the same!

R5 instead of 1dx3?

That's the decision I made. As a wildlife photographer, I considered upgrading my 1Dx II to a 1Dx III but I didn't see where I was getting that much more camera for the money. When the R5 was announced with animal eye focus and increased sensor resolution and a lower price, I placed my order. Now if it would only be shipped!
My decision to get the R5 was the same as amendegw's .... I will still have my 1DX Mark II for fast moving subjects (BIF's / Planes, etc.) The R5 for much of the rest that I shoot. As soon as I get the R5 my 5D Mark III is for sale. I should have placed my order on the original release date but I debated and analyzed the R5 purchase and did not place my order until 7/24 ... so I wait.

Rumored Canon EOS M7 camera specifications, and the end of the line for EOS M? [CR1]

.....
One *could* create an adapter (in either direction, though I imagine R->M would be more desirable) that used optics to alter the necessary difference, but as far as I know, no one has done this or even begun to do it.
For me, an adapter with glass is not a "problem". I appreciate there would likely be some quality loss but a big functionality gain. I'd be far happier with a Canon manufactured adapter as I'd have more confidence in communications. I assume there would need to be some software support as well so I assume/guess Canon would be doing it anyway.

(If I didn't say it (confused) it is an R (lens)->M (body) that I was asking about (as EF-M is already available).

Which adapter?

If you're willing to pay the "scalpers" their due, any of the adapters can be found on eBay... A couple of weeks ago I paid $165 for the basic-flavor of Canon EF to R adapter when I got tired of checking my order status at B&H 3-times-a-day... Paying a 65% premium to get-it-now may be a bit extreme (that's why I just opted for the basic adapter), but at least get to play with my stable of EF-glass on the R5 while B&H works on my backorder...

well the Viltrox version worked very well for me. $45 received my Canon version yesterday. Sold the Viltrox today.

EOS R5 or R6 Versus 5DMIV for Airshow,Sports and Wildlife thoughts .

Regarding the R5 in terms of battery life, I was out this weekend with mine at a local wetland preserve testing a couple different lens combinations and settings. I had the battery grip, with two batteries installed. I racked up 2200 shots in 2-3 hours and both batteries were still at 67-70% charge. Not as good as either of my DSLR bodies, but really not too far off either

Question about depth of Field with a 400 f2.8

With this information i think the 600 f4 is the right choice for me.

I will have to save a lot for it but in a few years i will hopefully own it.

The EF 600 f4 is a great lens like its other prime siblings. Keep in mind that with this series, when used with a 1.4X the optical performance is still quite good and even a 2X works pretty well.

The first attached photo is with the EF 400 f2.8 plus 2X, the second is with the bare EF 800 f5.6 and both were taken with a 1DX III and cropped to 12% of the sensor area. You always lose IQ with a converter but with some glass the bare IQ is good enough that the results may still be acceptable with a converter and sometimes this makes sense if you need a combination of focal lengths. If 560 f4 works for you, the EF 400 f2.8 plus 1.4X makes a very high quality and fairly versatile setup. Of course DoF is very shallow with this aperture and focal length.

Digital Photo Pro maxes out my i7 CPU

My older system does peg CPU out when opening a raw cr3 image in DPP. It goes back to zero after about 5 seconds.

Lightroom jumps to 50% cpu but immediately goes back down.

I’m used to around a 30-45 second processing time per photo with a RAW files from my existing cameras. Not blazing fast, but definitely workable for my needs.

Then, I decided I would download some files from the R5 just to see what that camera was capable of. And how long did one of those files take to process? ......... Almost two MINUTES. Yeah.

Patent: Inner zoom RF 70-200mm f/2.8 and RF 70-200mm f/4

I think they are purposefully segmenting the market, saying if you really want that length, you'll shoot the 100-500 which you can put extenders on. If you want speed, you'll put the 70-200 on the R5 and crop if you need to, if you want both you'll buy both ($$$$).

I wonder - what is the resolution difference on the R5 between cropping the RF 70-200 vs. using the EF 70-200 III + 2.0x III? A 50% crop in theory would still be higher res than the R6/1DX III.

Nikon - their biggest mistake?

As I wrote in detail in this thread: https://www.canonrumors.com/forum/threads/my-experience-from-canon-5d4-to-nikon-d850.37563/ I moved to Nikon F (just over a year ago) after twenty years with Canon. The D850 is the best DSLR ever made (my opinion, but also the opinion of several others). I love my 500PF lens, which no one else matches. It is also worth noting Nikon still makes and sells a (very expensive) 35mm film camera, which Canon has completely abandoned.

So why does Canon have a huge lead in sales? I will speculate it is due to the following...

1) Canon customer service and repair service is noticeably better than Nikon.

2) Canon has better marketing that includes sponsorship of big name pro shooters.

3) Canon has had a simple and consistent roadmap of lenses, meaning (as far as I know) every EF lens of every generation works with every EOS camera of every generation. Nikon has a confusing roadmap where generations change and lenses from certain eras do not work with cameras from certain eras, older lenses have physical aperture rings while newer ones don't, etc.

4) The 500PF lens, which is in huge demand and might have pushed some new users to Nikon, is perpetually out of stock to this day and always has been. I lucked out getting one quickly, but customers are on a waiting list up to eight months to get one.

5) Canon got an early lead in digital, with the 5D series and 1D series large megapixel sensors, when Nikon was stuck at 12MP for years. Many people jumped to Canon in the early days of digital and once they are invested in a system it's hard to win them back.

Weird color banding in my R6 photos (both JPEG and RAW)?

Nevermind. I figured out what the problem was. A few days before I got the R6, I borrowed a monitor calibrator. For some reason, it made my photos get the color-banding effect, as if there wasn't enough colors to represent my photos (I assume it had something to do with bit depth). It wasn't the camera itself - I just hadn't taken/looked at any photos after I calibrated the monitor. I reset all the monitor settings and now the photos look fine.
Yes, this is because of the bit depth. If you want best results use a monitor like EIZO that is able to be calibrated through hardware with 10bit look up tables. Perfect results with no banding with those monitors.

2019 global camera market share numbers are out, Canon leads the way

OK, how is the sensor cost different? The die for each is the same size, I am assuming that they are both made on the same fab line, in the same process node, etc. In which the cost won't be much different. Semiconductor cost is determined by the finished cost of the wafer divided by how many chips you get off of it (with adders for packaging, test etc.). So, if the finished cost of a wafer is $2500 and the yield is 25 chips then the cost per chip is $100 whether is has 25 MP or 50 MP. What you charge for it is a different story.

I still maintain that an EOS R6 and an EOS R5 are almost identical with a few differences (some of which I listed). I don't think there is a $1000 difference. That doesn't stop them from pricing it that way -- assuming that the customers will pay it and the competition doesn't come along offering something as good for a lower price. This appears to be what happened to the EOS R. I am guessing that there is room to move in the R6 as well.

Here are a couple different questions: Would they have priced it higher if the higher definition video modes actually worked well? Also, what is the use case for the video as it is? If you can only shoot for 20 minutes (and even that is qualified), after which you have to power the thing down and let it cool for 2 hours (?), in what situation is that actually usable? Can you still shoot stills if it has overheated like that?

Yield will not be the same for sensors with radically different pixel densities. There will be more errors on the smaller pixel densities, which will cause a higher percentage of the chips made from each wafer to be rejected.

Sandisk 64GB CFexpress does not support RAW video on EOS-1D X Mark III?

The reader I can buy locally, and will...but that shop has one card that's not fast enough... and S*ny. Whom I do not want to give one rusty zinc cent to.

I bought one of the highly regarded Sony Tough SD card (UHS-II). After about a year and a half, it started to corrupt files. Having an unspported DLP TV years ago was a big headache. Didn't think they could mess up SD cards... but then they had a large recall. Which is one reason why I've decided to use ProGrade exclusively.

R5, R6, 5D4, 1DX3 Low Light Tests

I'm surprised that a photographer with Jeff Cable's experience didn't have better control over his comparisons.

More interesting are his observations of how the exposure metering varied between models, but now I'm wondering if he had proper control of his lighting!

Yes it is, but maybe he knows more how to use cameras than how to pixel peep and DRone about cameras ;)
