Canon EOS R7 pre-sales discussion, hypothesizing, and prognosticating

R7 AND R19 HANDS ON VIDEO

https://www.youtube.co​m/watch?v=HOvUujBCwAM

Has anybody seen the panorama mode mentioned in detail on any of the videos? This is a feature I have really missed on my Sonys since Sony removed it from the a6xxx series. My a6300 has it, but my a6600 doesn't, and I used this mode a lot on vacation. As a matter of fact, I carried my Sonys probably 3-1 in the Disney parks as opposed to my Canons for just this very reason.

Snippets I have found on these smaller type features:

Then there is this article: https://sg.canon …Category=mirror​less-eos-r

I also found out that the R7 has a limited auto-leveling feature where it can subtly correct for level using the IBIS function.

Also this, if it works well.From above link. Hmm


"In-Camera Focus Bracketing

By using the Focus Bracketing feature in the EOS R7, users can choose to shoot up to 999 shots to capture different focus points within a scene.

These shots are then automatically stacked together through the Depth Compositing feature within the camera to achieve an image that is sharp across with a deep depth of field."

Other Canon mirrorless already have that though, so that isn't really new. My R6, for example, has that feature, as does the M6 II, etc.

I knew they had focus stacking, but did not know it could stack it in camera for a finished image. Learn something new every day.

EDIT: I just look at R6 focus bracketing on R6. It said this"In Focus Bracketing mode, the EOS R6 captures a succession of frames with a single button press, starting at the specified focus distance then moving incrementally towards infinity with each shot. This series of images can be ‘stacked’ into a final composite picture in post-production using software such as Digital Photo Professional, which is supplied with the camera."

So if that is true, it is not "in camera" in the R6.
Have you done this?

I believe the EVF itself is largely responsible for refresh rates, much like desktop monitors, TVs, etc. The R7 EVF is likely the same exact one found on the M50.

I don't see issues with my M50 like I did with the EOS R regarding lag/refresh rates, but the EVF is noticeably lesser in quality than the R6. Not a huge detriment, but it is noticeable when you use them side by side.

Yep, I totally agree with you that the screen (EVF) refresh rates are determined by the EVF circuitry in much the same way as a computer monitor's refresh rate is totally determined by its circuitry. Perhaps I didn't explain my thoughts correctly. Sorry for that.

The screen's refresh rate is only a statement of how often the display gets the information from the screen buffer and updates the individual pixels on the screen to match the information on the screen buffer. The rate at which the information in the screen buffer (just bits in memory) can be updated is determined by the processing complex.

I really like your desktop monitor analogy as it makes it easier for me to express what I was trying to say. Which is that regardless of the monitor refresh rate if the desktop CPU + GPU are not able to process the information to be displayed fast enough, the image can still be jittery and can have a much lower information frame update rate. In other words, even if you use the same old monitor, a new computer can generate a better viewing experience. For example, if your monitor can do 100 updates per second, but your CPU+GPU can only render 10 new frames per second, your effective information frames per second displayed on the screen is 10. The screen refresh rate only sets a maximum. You can still use the higher screen refresh rate to provide a smoother video by holding on to two frames and displaying interpolations between the two but at the expense of added latency.

But this is not exactly what I was commenting on. I was commenting on the latency or lag. That is, the time it takes between when the light hits the sensor and the corresponding image is displayed on the EVF. The EVF refresh rate sets a minimum. For example, with 60fps one can't expect the latency to be less than 1/60 ~= 16.7ms. But I suspect the latency for a single image is much larger than that and the effective 60fps (or 120fps) throughput is achieved by parallelism in the processor. This is speculation on my part, but regardless, the Digic processor definitively plays a role in the latency. How much of a role? I don't know.

The only concrete piece of information I have is the statement in the Canon Specification in the link I provided:

https://en.canon-me.com …as/eos-r7/specifications/

Where they attribute the following statement to the Digic X Processor: "Responsive control and minimal EVF lag".

This leads me to believe that the Digic processor plays a significant role in the latency and that the transition from Digic 8 to Digic X can noticeably reduce lag. Perhaps a better statement is that it gives me hope that it will have better lag Many times these statements are really more marketing than true technical statements, so we'll have to wait and see.

I agree. It may not have flagship features, but has everything that is needed for the wild life and bird photography.
Now only the performance is in the same lines and it's a great camera for everyone.
I will wait for real life reviews till I consider buying one. Until then R5 rocks.

Get out there on YouTube and do a search for R7 reviews and you'll find several. Canon had it out there in a few hands for a few weeks at least for early testing. The 2 reviews I watched were generally pretty favorable, sounds like a very good autofocus system, plenty of frames per second. Seems like problem are mostly trivial nitpicks.

I would be shocked if they moved the compositing function into the camera, I wonder if something was mixed up in translation from the source of that text. It could be in camera though, but I would be a bit surprised.

I have used this function, more of a test thing than actual usage in the field.

I remember stacking being mentioned in one of Canon's official videos/promos. So this is new, unlike those in other mirrorless where stacking happens in DPP.

One of the accessories listed is the multi-function shoe adapter. What is this? The description only talks about "dust and drip proof Speedlite accessories that you may already own."

Will I need this to use my existing 430EX II with the R7?

I found the answer to my own question, courtesy of a brief but very informative YouTube video with Rudy Winston.

The answer is no, you don't need the adapter to use older Speedlites with the multifunction shoe.

The adapter helps preserve the body's moisture/dust resistance when you're using an older Speedlite or other shoe-mounted accessory. Newer Speedlites, I infer, have the weather sealing built-in, so they don't need this.. If that's important to you, you'll want the adapter. Otherwise you don't need it.

Folks with R3's probably knew that already, but this is all new territory for me.

BTW, here is the video:

https://youtu.be/XrJi5​YpGLJ0

EDIT: Even if the weather sealing isn't needed, one "feature" of the shoe adapter is that it raises the flash up a little bit (maybe 1/2-3/4 inch?), putting it that much farther from the lens axis.

I'm 30mins from Gatorland and Jared didn't let me know he was in town! I'll just have to ignore his next 5 text messages.

Another 7D Mark II feature I don't see in the R7 is GPS.

With the new accessory shoe, Canon (or a third party) could make a very small add-in GPS that can be powered from the camera, and can return its data directly to the camera, all through the new contacts in the shoe. Smaller, no batteries, and no external cord like the GP-E2.

Given the fundamental shorter battery life due to the need to power the EVF's electronic display, it would seem to be a better design to allow an externalized self-powering GPS unit to be connected...GPS runs down its battery, you change the battery in the GPS without having shortened the life of the camera battery.

So 2 things, there seems to be 2 new capabilities here not mentioned before: Raw Burst and Pre-Shooting
a) A sequence of shots can be stored into a single file, then later you can pull out individual frames as full sized raw later (new DPP feature?)
b) At half press before you actually engage the shutter, up to a .5 second of images beforehand were recorded and can be stored on the card in case you missed the action with the full press of the shutter.

These are indeed two new and very interesting features.

Taken from this article, not sure if anyone has shared it yet?
https://www.canon.com.​cy …onnor-eos-r7-shoot-story/

If you read further into that article, you will notice the automatic panoramic mode the R7 has, where you just hold down the shutter and move, and it stitches the scene together for you, saving time in post processing. Depending on how well that works, it could be a gimmick or very useful. Again something phones have been doing for quite some time, so Canon seems to be doing a fusion of mobile photography tricks into the R7. Certainly makes sense, now we just need that "Make me old or young" filter too.

Thanks. I appreciate it T.
