I will be more tempted when Canon actually makes the 200-800 L lens they patented.

That and the 80MP R5S:

They're right around the corner.

It means quite a few operations, even if "trivial". As the "grid" is fixed it depends on the interpolation order how much work it is. Usually you need to sweep through x and y directions using sums of the neighbour values, all needs to be stored optimally in cache and refetched - it certainly will introduce overhead (this is something I do in computational fluid dynamics for a living on massively parallel computers) but is doable provided the processor is optimised to do things like this.


Also if you make an RGB file in the first step, you have lost some of the information of the original raw image. In "rebayering" you lose further information, so it would have been better to just store the RGB image from the first step. This is what I mean by the problem being non-trivial. There is no easy way to get a raw file of e.g. 24 MP from a 45 MP sensor without losing a lot of information.

Canon have implemented lower resolution full frame raw files in past cameras but in the R5 manual the only lower pixel count raw is a 1:1 crop from the center, as far as I could find. Nikon still have different raw sizes (both cropped and downsampled (with some witchcraft algorithm)) but I see the latter as self-defeating and pointless. The files are soft (compared to what you'd get from a native sensor of the file's resolution). I don't think Sony offer the lower-resolution full sensor width raw files.

I would like such a mode for the A7riv, but only if there is no penalty felt in real life shooting (processing power, DR etc.).
There was a rumor once, but I didn't hear about it any more.

look again:

1) as usual, he's not using sony real-time tracking, fro still doesn't know what that is, lol

2) the sony is framed differently in the first test, which could mean that the eye is smaller in the frame, it's a disadvantage because there are fewer af pixels on the eye

3) wrt to sony, the default af settings that he used are not optimal for what he's shooting

I wish I had the r5 to test. But sadly, no.

Not sure where you are getting your AF information, but the only video I've seen so far with shooting "action" is the one I posted earlier from Jared Polin. Seems like the r5 tracks as well as my a9 and a92. I'd love to test them for myself. I thought the same thing when he spoke so higly of the a9. Eventually got one and you know what, he was right.

Why can't you use the electronic shutter for sports/action? I've not seen anything that says you can't. At about 4:16 of the video, he switches to electronic shutter and it appears to work flawlessly.

The a6600 for pro sports work? Are you serious? I can't tell.

Also can't tell if you are seriously asking what good is more MP if you crop anyways. Um, it's so you end up with a higher MP final image. You know, so that big play that happened 60 yards away and is only in 1/3 of your frame, you can crop it and have a high MP image left.

i'm wondering if you have personal experience shooting large field sports with an r5/300mm prime.

r5 does not have a stacked sensor, so it does not have a9 af capability, it's apples vs. oranges.

since you can't use r5 electronic shutter for sports, you are limited to 12fps or less, depending on which version of 300mm prime is used, read it for yourself in the canon r5 manual... early versions of canon lenses are not supported at 12fps.

what good is more mp when you are cropping it away?

a $1400 a6600 will give you higher pixel density than an r5, with sony real-time

no, that's not the scenario you just claimed, with your 300mm lens shooting a large playing field, and no, higher pixel density with 24mp aps-c means more pixels in the image than what you'll get with a cropped 45mp r5.

beyond that, the advantages of a stacked sensor have been discussed at length in this thread, i'm not going to repeat it.

for those who think that the r5 is a pro camera, see page 284 of the r5 manual:

"General Still Photo Shooting Precautions

Image quality:
-When you shoot at high ISO speeds, noise (such as dots of light and banding) may become noticeable.
-Shooting in high temperatures may cause noise and irregular colors in the image.
-Frequent shooting over an extended period may cause high internal temperatures and affect image quality.
-When you are not shooting, always turn off the camera.
-If you shoot a long exposure while the camera’s internal temperature is high, image quality may decline. Stop shooting and wait a few minutes before shooting again"

i already explained real-time tracking to you, just a week or two ago... place the af box over the target, hold the af button down, then re-compose the shot however you want.

fro is not doing that in any of his sony videos, he doesn't have a clue how to operate sony gear.

look at how he's got the af box set at a fixed location in that video that johndizzo posted, that's obviously not real-time tracking.

It's actually something I was trying to learn more about - real time tracking on A7RIV/A9 (I even have a thread about it here )...
Can you tell me what's the difference between using the tracking mode and relying on eyeAF?
Would eyeAF engage earlier and track better if triggered through real time tracking mode?
I don't really see how it would make a difference here, as the point was to let the camera pick the eye on its own and keep it in focus as soon as possible... Jared also explains why he has the the af box on the screen in the video, also saying that the same is possible with Canon...

the advantages with r/t tracking are obvious, see the video, for one thing you don't need to hassle with a dedicated eyeaf button, and you can start tracking a person while they are still a tiny size in the frame, long before the camera can discern a face in the scene.

beyond that, they both ultimately rely on the same eyeaf capability... sony always has to recognize a face first, before it can look for an eye, that's in the manuals, canikon probably works the same way.

j4nu wrote:

depending on how it's used, yes, for one thing, with r/t tracking you are telling the camera which person in the frame to focus on.

sony wide mode af tends to default to the closest object to the camera, it's constantly scanning the entire frame vs. just the target r/t tracking box area.

so do you want the a.i. capability diluted and weakened by having to constantly scan the entire frame, or just the r/t tracking focus box area.

j4nu wrote:

see above.

you appear to think that r/t tracking offers no advantages, which is ridiculous, see the video below.

"Real-Time Tracking can completely change how photographers shoot, changing parts of the process and how they mentally prepare for a particular shooting situation. This is not an overstatement, it really does have that kind of impact."

Thanks, in the meantime I stumbeld into this post:
https://www.fredmiranda.com/forum/topic/1659672/0#15319407
which sums up RTT vs EyeAF nicely.

I also think that the way Jared setup the test might be a bit biased, as I think the premise was to let the camera do most of the work, so no manual selection of zone/flexible spo/etc which would allow RTT to kick in before face or eye AF.
Then, as you wrote earlier the difference in fov of the lens used also plays a role in how well eyeAF works.

yes, and there is a place for wide zone af, i.e., bif against a distant background.

it fails in his test scenario, tho, for all three cameras:

1) canon af grabbed him first, but then focused on the phone pole behind him
2) sony apparently focused on nothing?
3) nikon focused on the car way in front of him.

now look at sony a9 real-time tracking when it's fixed on a target that's smaller in the frame than jared is there... sony nails the af, at 20fps af-c, just about every single time.

of course sony doesn't have an exclusive on manually targeted tracking, i think that nikon for instance still owns that space with dslrs, and canikon has implemented some version of it on these milc bodies.

it's just funny that we are 60 pages into this thread, and i don't think that any of these r5 proponents have been informed enough about canon to have pointed it out here.

IMO, this is overly assumptive on multiple levels.

Personally, I've shot the A9 extensively since getting my preorder back in 2017 and have been through all the iterations of the FW through 5.0 when R/T tracking was introduced. Additionally, I'm fully aware of how it is different from simply allowing the cam AI to identify faces and eyes in wide AF. Some of us actually use the AF system this way a significant amount of the time versus targeted initiation of R/T tracking (me being one of them) which in turn makes the test that Polin did, very applicable for my use case.

Also, I recently picked up an RP for grins and to use with these RF lenses in the meantime to get a feel for how the system operates. What I can say is, for the way that I shoot, Canon's implementation of their face/eye detection, tracking/initiation, etc show a ton of promise just in this throwaway body. The R5 (I assume) will only build significantly on that as it is Canon's latest tech and progression from their first attempt at FF MILC.

Lastly, I don't think anyone here is attempting to declare that the R5 is better than anything else for all use cases. I know I'm not. So I wouldn't call myself an R5 proponent as a generalization of preference over anything else, for everyone else. But based on the experience I have had with both the Sony system and what I have seen so far from the RF system, the R5 appears to be a good fit to go alongside my A9 as my high res solution. Close to or on par is the measure here for many of us. Being better than in certain facets would merely be a bonus for me.

as i just proved with the video freeze frame, polin obviously did it wrong, he should have used targeted tracking on all three cameras, because they all failed with wide area af.

so if that's what you are doing, you are not getting the best possible af results.

i don't get the need to defend something that's done wrong.

r5 makes sense for you because you still have a stash of nice ef-mount glass, and r5 af is better overall than any dslr af that canon has, including that $6,500 1dxmk3 boat anchor... if i was in your situation i'd be looking hard at the r5 as well, in part because sony cripples a-mount and therefore canon brand lenses to 10fps af-c.

but is that situation something that belongs on a sony forum? i think not, we don't care about canon bodies on canon glass, it's not relevant to sony.

there have been multiple posts in this thread that claim that r5 af is somehow on par with a9 af.

there are over a dozen fake accounts on dpr, that all say the same thing.

Well, there should be 2 tests, one with face/eye AF and second with tracking capabilities ... but the way the single test was setup (using default settings) it shows only part of the picture.
... but in that part both Sony and Canon prove to be capable cameras, with Nikon trailing behind a bit.
.. also I would not call not getting 100% of the frames in focus a fail, as then all our cameras would have to be considered as "failing" .

Not all scenarios are better served by targeted tracking as many around here can attest to. Precisely why I wouldn't call what Polin did, "wrong," solely based on what you've determined to be the one use case scenario everyone should be using for all the times they would need face/eye detection. I'm not defending something someone did wrong, just pointing out a wrong assumption that one has made based on their subjective determination.

With regard to crippling, it isn't just about FPS for me. In all reality, that's probably at the bottom of my list of concerns. The biggest issues I have with some of my EF glass mounted to my Sony bodies ranges from limited usable AF area in the frame to no AF-C in continuous burst. I'll take 5 FPS if I could at least ensure those two things are working properly.

Lastly, I continue to fail to understand why it is a problem for so many forum members to see this specific thread on the Sony forum since it is clear in what it is asking for - what do Sony shooters think (from their perspective as Sony shooters) about the new Canon bodies? Placing a thread asking for the opinion of Sony shooters on the Canon forum would likely be much less productive for the OP. Furthermore, if a thread doesn't interest someone, they can choose to not click on it and/or participate in it. Imagine if we all concerned ourselves/policed and paid attention to every thread in the respective forums we frequent. I would almost feel like a "forum Karen." Also, there's not enough hours in the day.

I've been in this game long enough and with a lot of coin invested in every system to know that no company has been king forever in this space. Also, this field is the epitome of the phrase "horses for courses."

I get it, You don't like the camera. I'm intrigued by it. Maybe it will work, maybe it won't for pro sports. Time will tell. But I'll bet you a cold beverage I see more r5's on the sports sidelines and baselines (If I ever stand / sit on one again....) than I will see Sony bodies of any sort.

I actually watched the whole video you linked, It was painful. His technique, framing and use of a mirrorless camera seemed pretty far off. For sports like football, I'm not using face and eye AF. Most of the time you can't even see them and they are certainly way too small most of the time to try to follow. Same with my a9's. I am aiming mid-body and trying to follow a player through a myriad of distracting subjects. If you read the accompanying comments on his video, he tones down is critique of the camera considerably.

"John Gress
1 week ago
I think the AF is great! A friend who shoots sports full time looked over the images and said the in focus percentages were very good and in the studio it was almost 100%"

Sensor read out speed is an issue that needs further review, especially if you want the 20fps electronic shutter offers. It is a reason I don't shoot with it with my a7r4. But I still take the a7r4 to sports events and shoot with it. It has value in some situations, but no, fast action is not its forte.

I still disagree about the number of pixels. It's clearly an advantage for a shooter who is focal length limited, by situation or budget or both. Simply put, very few folks can afford the Sony 400 2.8 GM and having a 2.8 lens at night or for indoors sports is necessary. A 300 2.8 is much more affordable. So, my point was that an r5 paired with a 300 2.8 will be much better option for someone looking to go mirrorless. With Sony, their options are fairly limited. You can try adapters and adapted glass (been there, failed at that) but it's not an ideal situation. I think from everything I've seen and read, the Canon EF to RF adapter is pretty seamless. I don't think anyone looking at the R5 is interested in the small sensor a6600, at all.

So, for some Sony shooters, it could be intriguing to go for the r5, even with the limitations of a slower sensor readout speed and maybe missing some shots. Alternatively, they could shoot with a mechanical shutter and loose some FPS. Certainly there are limitations in both scenarios, but I believe, maybe wrongly, that despite these limitations, some will find the lure of the r5 great.

I'm guessing you have also never used the r5 paired with any long glass, so we can assume you are also speculating, which is fine and what most posts in these forums are doing at least until we can get more real world users putting the bodies through the paces.

As for the comments about real-time tracking. It's great for some sports where the athletes are isolated, but miserable and unusable for some sports, like football and soccer and even baseball most of the time. It's just not consistent enough to stay on the right target and once it grabs the wrong target, the action is over before you can reacquire the intended target. It's a great tool to have on the belt, but certainly no panacea.

And maybe I need to step away from the keyboard for awhile, but I'll end with this. This Canon r5 thread in the Sony forum is now 58 pages and growing... Clearly, it has ignited some interest in Sony shooters, even if you are not one of them.

no, that's not the scenario you just claimed, with your 300mm lens shooting a large playing field, and no, higher pixel density with 24mp aps-c means more pixels in the image than what you'll get with a cropped 45mp r5.

beyond that, the advantages of a stacked sensor have been discussed at length in this thread, i'm not going to repeat it.
