Review: PowerShot G7 X via DXOMark

[Canon Rumors]

<p>DXOMark has completed their review of the Canon PowerShot G7 X. They have come away pretty impressed with the camera and it’s very good sensor score, which bested the Sony RX100 III in their tests.</p>

<p><em>“Although it was Nikon who was first to adopt and popularize the 1-inch sensor format, it was Sony who dominated this format with the RX100 series. Now with Panasonic and Canon adopting the sensor the field is opening up. The G7 X has high-speed lens with widest range that sets it apart from the RX100 series but if the 24-70mm lens on the RX100 III is enough the Sony is the better specified of the two but then that’s reflected in the steeper price.”</em></p>

Are these color depth and dynamic range values are independent of sensor size unlike low light iso. What kind of photography benefits from Camera with better color depth and dynamic range. G7 X has better dynamic range than 6D and better color depth than 70D. Nikon D3300 which goes on sale for $399 with kit lens, has better dynamic range and color depth than 6D. When it comes to low light ISO, bigger sensor always gives better score.
Thanks

Are we now liking DXO?

No.

My opinion of them is unchanged. I use their software and find their measurements useful (except when they make errors). Their scores are still BS.

While DXOMark scores are still considered as rubbish, the base ISO DR data for G7X is interesting. 12.7 eV is wider than that in all of Canon sensors, including their top end 1DX.

Hmmm....

I don't really 'get' the scores either. Comparing with the RX100III and GXII raws a week ago, the DR sure did seem on par with the RX and much better than the GXII. But high iso seemed much worse than the GXII. It does have that 'Sony DR'. No idea how it really compares to FF Canons though.

Also some reviews saying the lens is 'sharp corner to corner' is not what I have seen.

then there is the 1fps in RAW?

I really want to like this. 70mm is just too short, otherwise I'd be looking at the RXIII. The GXII is much larger and has the 'usual' Canon DR as opposed to the nice Sony DR. Like I said, I don't know about the FF, but DR is better than Canon's crop sensors for sure.

Still need to see more real reviews, but I have a feeling I'm going to pass on this one. If the RXIII was f2.8 at 70mm and then went to f4 at 100/120mm, I'd go for that.

Canon, do you hear us? We want a 50MP high DR Sony sensor in a 6DII body for 2500$. It doesn't need many focus points, it doesn't need the best low light performance, it doesn't need to be fast. We want many good pixels at ISO64 and an EF mount.

Good question

My answer:
Nope! Not me!
I still give a d!§$ s%&? on thier scores. They should focus on programming and selling their sw.
There are better "experts", "reviewers" and "specialized" magazines out there.

G7 X seems to be a good move concept-wise but I too observed the not so good corner quality in ONE site, it was d p re view if I remember it correctly. We have to wait for more well made comparisons.

For me the G7 isn't interesting - I am very satisfied with the EOS M and the EF 40mm lens via Canon adaptor. It is compact, low weight and delivers great IQ. It's also a movie capable (+ Magic Lantern features) backup camera for my 40D + fits snugly in a lens compartment.

Me too! But I would accept a Canon sensor too if it has real 13 bit DR or more ...

I don't.

What do you need 50mp for in a cheap camera?

So $2500 is a cheap camera??? Anyway, I know exactly what he is looking for...a 2014 version of the 5D2 but with 50Mp for landscape work.

The 5D MkII was replaced by the 5D MkIII, and it was a massive upgrade in every respect that the MkII got criticized. Indeed it is probably the best general purpose camera made so far.

How do you think your "landscape work" will benefit from a 50MP 135 format sensor? How does the D810 not fill your needs? Why do you think a 50MP 135 format will touch the IQ in big prints of the 645z medium format 50MP sensor? How does stitching let you down currently?

I know there are a very few photographers out there that will get the best out of a 50MP 135 format sensor, but most of us are kidding ourselves if we think we need it.

When people like Jimmy McIntyre can shoot images like this on a daily basis with a D800 and 60D, and I'll bet you can't tell which is from which without big prints in front of you, I think the 'need' for 50mp is just hype for 99.999% of people.

But I'd love you to prove me wrong..........

+ 1000 on this.

BTW how did we get there in a thread about a compact p&s.
Does anybody want/need a 50 mp 1" p&s?
Me not!

Nope - still couldn't give a toss what they think...

IMO 50 MPix have the advantage to dig into an image, e.g. landscape, macro, "townscape" to explore details - one photo for everything. On the other hand I see a strong advantage for the binning of 4 sensor pixels into one RGB image pixel with full color information ...

And this is also true for smaller sensors with better light.

 

[Maximilian]

I'll give it another try:

HELLO GUYS!

This is a thread about the PowerShot G7 X.
Not even 2 pages and you're only talking about a 50 MP FF???

That's really hijacking. Cool!

So your 'need' for 50MP is so you don't have to carry a long enough lens for the job (just get a current crop camera to do that, they give you an effective 45MP sensor already), and, to down sample to 12MP to get a colour bit depth no device can replicate or print and the human eye can't discern.

Forgive me if I am not impressed with your arguments.

I'm with Maximilian here, you'd have been better off not hijacking the thread.

No Need to impress someone.

I just like to view images in the above mentioned manner. You haven't understood my point.

Pixel binning for images with red LEDs to avoid artifacts.

No need to call answers of your questions hijacking ...
