There are still surprises in store for the Canon EOS R5 announcement [CR2]

[MaxDiesel]

"Since they noted, no more EF Lenses this would be a good trade off."

Did they actually say this somehwere? I have heard it a lot but not actually read anything official.

According to several articles including this one:
https://www.digitalcameraworld.com/...non-no-new-ef-lenses-unless-market-demands-it

I was still hoping for a 24-70 f/2.8 with IS, for my C200 run and gun situation, I would be very very happy to ditch the 24-105 mkii.
Tho with an adapter I’d be ok to invest in RF lenses since I’m quite interested by the R5.

Interesting fact: when I google images by 'cripple hammer' keywords, google shows *only* the images of Canon cameras. Fascinating.

Which demonstrates the noxious influence of some crippled Canon hating brains...

Does no one else find it odd that Canon themselves have said nothing about this so called upcoming release event? I don't know anything about Canon's press release history, but I would think with only 8 days to go that they would have already started the hype machine and provided some kind of countdown to the press release. According to their calendar, July looks like a very quiet month: https://www.usa.canon.com/internet/portal/us/home/about/newsroom/events/#calendar

im with you here, its awfully quiet for a huge release a week away

It's actually totally quiet on any future events, the calendar only has past events.

Also, in many sports/action/wildlife long lens situations it's useful to keep the other (usually left) eye open to see things approaching from outside the field of view, but people who have done this tell me it's very unsettling that your two eyes are now out of sync. EVF lag will never be zero of course, but I imagine there could be a point where it is so close to real time that the brain can handle it.

I use this two-eyed technique, and the Panasonic S1R is the mirrorless I've tried doesn't give a little trouble with timing. Sony's are pretty bad this way. It's bad enough that it gets worse the more frames you shoot. The electronic viewfinder pretends to be unobstructed by showing you a quick image of the picture you just took. This gets a couple milliseconds further behind each frame, until you think you're shooting the bird, and then you realize you're shooting behind the bird completely. I've seen Tool complain about this, but hadn't seen anyone else notice. I notice.

Myabe R5 and 5D at the same time?

Funny to watch the guy's over at DP Review trying not to even mentioning Canon to avoid violating their NDA. You know that they have all the new Canon gear sitting just off camera. I imagine they'll have hands on reviews ready to go on announcement day.

DPReview TV: A call for slow, professional full frame lenses

Professional full frame lenses are usually large and have fast apertures. In this episode of DPReview TV, Chris and Jordan argue that there's a need for slow professional lenses – inspired by some of their favorite Micro Four Thirds lenses.

Yeah you could extend the dynamic range that way, but it would not make "20.000 iso that look like they were shot at 6.400 iso today". Sony and its sensors have dual gain too (similar to BMPCC), and it does help a bit but just a bit (less than a stop). The noise introduced by the camera is so small that there just is not much to gain there.

The dual gain doesn't make your sensor better in the dynamic range category. Dymamic range is all about the capabilities of light gathering by the sensor itself and being able to distinguish between the most minute voltage differences (i.e. gathered light differences) of every pixel. Dual gain (analog) is all about noise performance at various iso settings. It's about avoiding digital noise. And as you say, sony cameras that do use dual iso perform very well at high iso with little noise.

Well, as I stated in my first post, which you apparently read, I am here because my current brand is almost certainly about to be resigned to the history books, and I am exploring options for the future, and I am very excited by the EOS R5, and if I wasn't, I would not have even found this website.

If you seriously interpret my posts as "bashing" Canon, I suggest you take a chill pill and remember that Canon is a corporation, not your grandmother.

It's actually kind of mind boggling how you could reach that conclusion when my first two posts aren't even about Canon, but just general commentary on camera features, and the third is just genuine surprise at learning they don't offer a basic software feature that everyone else does.

And your shining personality continues to shine on through.

" And I'm starting to remember why I grew to hate Canon over the years. "

Yeah. Can't understand why someone might interpret your posts as bashing, considering this is your tone right out of the gate.

Shoots 3-D full-color holograms. You heard it here first.

 

[Mt Spokane Photography]

eh aren't mirrorless camera's kind of supposed to give you that feature that you don't really have a delay on your evf because you already see directly from your sensor what you are going to shoot? hence 'mirrorless'? (correct me if i'm wrong)

There is lag, and its noticable.

What are you talking about? Noise inherent to light isn't relevant here...
I'm talking of the noise that is introduced by every camera when you set your camera to higher ISO settings. When you set your iso on your camera, all it does is digitally amplify the signal coming from the sensor. Before that though the micro voltage coming from each pixel goes through an analog amplifier which basically gives a camera its base ISO (let's say base ISO on your camera is 400). This is your cleanest ISO. When you change your ISO on the camera, this signal is then digitally amplified upwards or downwards depending on your setting. This is where digital noise is being introduced. This is basically comparable to digital zoom.

You're understanding here is a bit off. Increasing the ISO value actually decreases the electronic noise in the image. The reason images at higher ISO tend to be noisier is because you're trying to create similar levels of brightness with less light which increases shot noise just like the other poster mentioned.

Dual gain (analog) is all about noise performance at various iso settings. It's about avoiding digital noise. And as you say, sony cameras that do use dual iso perform very well at high iso with little noise.

It does affect dynamic range as well, especially with the Canon style implementation when electronic read noise is the limiting factor. It's very similar to the DualISO implementation in magiclantern where the high ISO signal is used to reduce the effects of electronic read noise in the shadows while the low ISO read is used to maintain highlight headroom. The advantage of using it with dual pixel sensors is that you avoid the whole "half vertical resolution" thing from magiclantern's implementation.

Depends on the camera, quite a few of them are in the single digit ms range for EVF lag now which is not really perceptible at all.

See Astrotracer

Ah yeah. I wasn't thinking about that. My astrophoto experience is mainly higher mag, longer exposure which this kind of thing would not help greatly. But it would be good for the combo landscape/asto stuff!

 

[Eclipsed]

I don't think this is possible within the camera body, unfortunately. You need a tracking mount to do this for long enough to get night sky exposures. But star autofocus would be cool.

Imagine a 20 minute exposure. That's 5 degrees of image shift at worst (at the celestial equator, less nearer the poles). With a wide or normal lens that is very little cropping to essentially "stack" a long sequence of exposures. For telephoto, it means that a tracking mount is not alignment critical. Notably, a smart system may well accommodate even rotational drift, and could include lens profiles to convert to a sprical projection for each image and then back to flat..

 

[Eclipsed]

Removing the IR-cut filter and replacing it with an specific IR filter would allow you to shoot infrared images without modifying your camera. And yes, this would have benefits for astrophotography too.

Anyway, pretty much zero chance of this being the secret new feature!

I'm wondering if there would be a good way to implement AF assist in the dark with an invisible IR illuminator.

I don't think the IBIS system has a ton of range of motion, so that will ultimately limit how long a single exposure can be to keep the star on the same pixel. You won't get any where near 20minutes. By cropping a section of the image and 'following' it across the sensor and the stacking it up, you are looking at a software solution vs. a hardware solution. Still, could be interesting. This technique is readily available in free software outside of the camera (on your computer), including the rotational correction. Could the horsepower of the processing required be contained in this generation of camera? One day it will be, but we'll find out in a week or so if it is! If so, imagine all the other things it could do!

 

[geffy]

it has a Nikon mount............

 

[amorse]

The article says there is another surprise for photographers, but it doesn't necessarily indicate that it is brand new technology exclusive to Canon here. I'm inclined to bet it's a pixelshift mode to increase resolution or color detail. Adding IBIS and not taking advantage of pixelshifting, as is done by other manufacturers, seems like leaving an opportunity on the table and I don't think there's been mention of it yet.
