Sarman 2525: The 8 stop IBIS is really cool.
Its a big advantage for Canon.
This is something Sony will never come close too because their mount is too small.
If you look at the Sony mount, it already covers the far corners of the sensor.

This is a real problem. It means the camera cannot shift the sensor without the corners getting blocked even more.
If you've ever seen a video of good 5 axis IBIS in action it really has to move the sensor around.
So Sony is stuck with very ineffective IBIS that doesn't work well at all during video.
Watch any comparison video and you'll see how bad Sony IBIS is, and sadly it can't get any better.

The reported limitation is for 4K HQ. From what I understand from Gordon Laing video (see the menu display at 15:05), the 4K HQ can be disabled.

mariuss: I was prepeared to buy it asap it will be on sell. Even preorder it (my first time) withouth any reviews.
My dream camera, i thought ... till today, when i saw this:

Bang! Thank you Max! I hate you btw. :)

Really Canon? I understand overheating in 8K ... i understand overheating in 4K 120p ... i even understand overheating in 4K 60p till some point ... but pls, really? Overheating in 4K 30p??? And then the cooling time required to use the camera again ... .

Now i will wait for realtime reviews, but i wonder, what can it change when Canon itself recognize the issue?!

I also wonder if R6 have the same heating issue.

For the limited info on the matter, what I understand is that the limitation is for 4K HQ at 30p, which is an oversampled 4K. The question remains for true 4K 30p (no oversampled).

noirdesir: I hope they measure the sensor sizes.

from FL, no change, and the UWA is about the same as x2 module.

keeponkeepingon: So this is similar to sony in that they have a 16:9 screen displaying 3:2 aspect ratio images.

While it's great for video, full res/uncropped images will be letter boxed on the left and right.

This drives me crazy on my A6000 as stills look significantly smaller than they do on an equivalent canon.

I'm too lazy to do the math. What would be the diagonal size of the 3:2 image displayed on the 16:9 screen????? 2.5"? 2.7"?

Thanks!

9*sqrt(3,5^2/(16^2+9^2))-2*sqrt(3,1^2/(3^2+2^2))=-0,00366
How am I wrong ?

buratino: DPReview: "Lenses
One of the biggest distinctions between the cameras concerns their lenses. At 24-200mm equiv, the Sony by far offers the greatest reach and the most flexibility. However, the F2.8-4.5 maximum aperture range is considerably less bright than the F1.8-2.8 lenses fitted to the two Canons. The graph above shows how those apertures compare as you zoom in (a lower number is better)."

DPReview, you compare three 1"-sensor cameras in terms their lenses BRIGHTNESS, which you express in F-numbers. And then you refer to "the graph above" using the equivalent apertures!

If you want to just look objective enough, give us yet another graph, without equivalence.

If you want to be even more honest - still with equivalency - admit that all 3 lenses (or at least 2 of them) do not cover full sensor area at their widest settings - which actually requires the equivalence to be recalculated, because the diagonal becomes even shorter.

Because the graph is log-log, it will look exactly the same without equivalence.
That said, I agree the graph should take into account the croping at WA for the 3 cameras.

In reply to:

Dragonrider: Looks to me like the g5x II wins the image quality contest hands down. Much lower high ISO noise, a bit better in the ISO invariance test and when you throw in the considerably faster lens, it will be the IQ leader. Also note the lower right corner of the lens on the tested RX100 VII is pretty bad.

For people only interested in stills, the AF advantage for the Sony is negligible.
And I would not want to sacrifice 4/3 stop of light for the 120-200mm range

FoxShutter: It’s an RX100 series killer , at least for stills . The colours are amazing comparing to the Sony’s dull rendering with poisonous greens.

What is your screen dpi and the viewing distance ?

What is missing for the comparison is what the camera could have been done in jpeg if properly exposed

What is the problem with lens sharpness ? At what size and distance are you looking at the pictures to make such statement ?

photofan1986: Nice colors, but it's about time to offer a quality lens on such an expensive camera.

The lens seems fine to me. At which size and viewing distance you are looking at the picture ?

jl_smith: Looking at the 100% of the landscape shots, this lens looks a bit mushy, even with the edited the RAW. I'd love to see a proper landscape shootout between this, the RX100 and the RX10, as I'm considering all 3 (yes, I know the RX10 isn't pocketable, but its range is nice)

Can you be a bit more specific about your need : 100% means nothing. Can you precise the dpi and the viewing distance ?

again, lens quality does not seem to be a problem here.

WA lens quality seems totally fine for landscape

In reply to:

davids8560: Would it be accurate to say that, regardless of sensor or lens, any compact, fixed-lens camera will have deal-breaking flaws and shortcomings which make it inadequate or unacceptable for "serious" photography?

no.
You should stop focus on weakness and start focus on strengths.

So Canon has not sent a G5x2 to dpreview while the camera is already in reviewer’s and consumer’s hand. That say a lot.

GoodKnight: Honestly your better off with a good smart phone. All anyone will do with this camera is share images on social media. Or put them on a back up drive where they will be lost forever. It isn’t really capable for much more. This isn’t a landscape or wildlife or sports camera. Just use your phone and save your money.

@gravis92 : “The large sensor is important because it negates perspective shift for the same angle of view.“
No.

bottom of page 3, ISO and connectivity : “and an option to have the camera choose that minimum shutter speed automatically. If you choose the last option, you can bias it either faster or slower than the default option, which is 1/shutter speed.”

1/FL
