I use the initial point in auto tracking and place it on a face and hit the AF-ON button to start tracking.

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

Is anyone knows when it will be available to buy?

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.

As suspected (& hoped) a quick firmware update fixed all issues with the Sigma Art 35. I couldn't be more pleased with how my stable of "old" EF lenses perform on the new R5! Though the Sigma Art's may not be much faster to lock-on focus, the improvement in focus-accuracy is a joy to see & use!

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.

Have a look at https://gist.github.com/marcan/858c242db2fc595da1e0bb70a05192fc as well

I don’t recall which one I went to, but thanks for the guidance Alan, appreciated. I will return with a smaller lens then next time!

I had no problem panning them with the 5DIV set to the central 9 points. They are very fast but travel in absolutely straight lines.

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.

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.

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.

Click to expand...

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.

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?

Click to expand...

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.

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.

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

The touch to shoot option is off, or I'd really have a mess. The delete button recenters the AF point. In order to hold the camera with one hand and operate the lens zoom or focus ring or control dial with the other, I need a good solid grip. My fingers do not work well, so I can't even feel the shutter button, its by memory as to its location which means always having my hand in the same position. I rcceived my R in the first batch shipped, and have used extensively it alongside my 5D MK IV. I finally sold the MK IV because the R was getting the most use even with the AF point issue. When I can, I'll let the camera pick the AF point, but that's pretty rare, it picks the closest point and that is usually not my subject..

Click to expand...

Gotcha.

And the lock button isn’t something you would / could use? I still want to refine how but in some instances I have used it rather than have wrong iso and under exposed.

I’d like to ditch some of my bodies but 2nd hand market in HK doesn’t give the best price and selling private Isn’t much on an option. Hopefully soon.

Canon was way to successful in marketing the red ring L glass that the green ring immediate makes me think it is inferior and the mark I 400 DO and other early DO lenses didn't do it any favours. Going forward I am fully expecting all the fast super-tele lenses to be DO lenses and red ring L lenses.

I got the JJC clone for it (LH-52) and then a JJC wide angle 52mm hood. Alas with the hood I can't get the lens cap on, but I dont mind that too much. I get protection in case I get a little bit of protection with the JJC (LH-52) in case I get too too close trying to do macro or soemthing, but when I want protection instead of a UV filter, then I have the lens hood which is small and light. Combined I think both were about 250 HKD.

You probably got the earlier batch? Hope you can get your update soon. I’m curious what was fixed. =)

Click to expand...

my seial number ends 000201 likely it is the number 201 of the production line, puzzle by the fact that it ships with two firmware yet no updates

Has anyone used a 400mm f/5.6 L, which as no IS, on an R5 with IBIS? I still prefer this old prime over my 100-400 II for BIF due to its optional 8.5m close focus limit. I wish the zoom had an additional 10m focus limit option so AF can't get so easily lost in a clear blue sky. Of course I wish the 400 5.6 had IS like the 300 f/4.0, but it doesn't.

Does IBIS provide a stable image through the EVF? How does IBIS compare to IS in the lens for 400mm and longer focal lengths? Since the 100-500mm RF zoom has IS in the lens, does that imply IBIS isn't very effective for long lenses?

The IS in my Canon 10x42 L IS WP binoculars (500mm equivalent) is simply stunning. I cannot imagine owning 10X binoculars without IS, and this L version runs circles around non-L Canon binoculars with IS as far as image quality.

You're welcome! I hope it goes well!

Sounds a bit daft to switch systems, it is more likely Canon or more likely Sony are going to sponsor him.

Hmmm, you may have a point. The fact that he has not committed to a new system yet could mean he is fishing for a sponsor.

Good to know, looks like you were very unlucky with your batch!

Upgraded my Mk3 last night, was shooting the kids in low light with my 35II, tbh I was not blown away by the new eye AF...

So I was out yesterday shooting a little video, and for the life of me, I couldn’t get the autofocus to work in video. At first, it didn’t want to recognize faces/eyes when in EyeAF, and when it finally did, I could see the box around the eye, but the focus motors wouldn’t even try to get it in focus. Even out of EyeAF, tapping on different sections of the screen didn’t make the lens refocus. In photo mode, everything worked great and AF was fast and responsive. Am I missing something, or has anyone experienced this issue?

It was the first time I used my camera since the latest firmware update, so I’m wondering if that is to blame. I’ve only tested with the RF 24-105 f/4, cause I couldn’t just start doing some testing while in the middle of a shoot and as we’re losing light; I had to shoot everything in MF, hopefully it’ll look decent
