How valid ? that is indeed the Q. If one is a fan of other-than-Canon...valid. If a Canon fan...not. If multi-brand user like me...minor validity. Minor.

Canon G1 X sensor review

The Sony is a great camera, there's no doubt about it but people are being unfair in their criticism of the G1 X.
The G1 X is the best compact camera ever made. Now I know that may sound ridiculous but even DXO agrees with this statement.
If a person wants a compact camera, doesn't want to be bothered with changing lenses and the additional expense involved with an interchangeable lens camera, there is nothing better than the Canon G1 X. (Naturally, all this may be BS. I'm still waiting for dpreviews' opinion).

I still expect outstanding images from the G1 X which is going to be very near a DSLR.
People should look at the pictures and compare first then the charts.
The g1 x has the advantage of producing pictures with much less noise at any iso though, with the x10 even at low iso you will notice more than you would see in cameras with bigger sensor such as the g1 x.
Agreed.
At pixel level there is significant correlation as long as we compare the same technology level pixels (or maybe I misunderstood you somehow - always possible, or you were a bit sleepy
), though less than many think as while bigger pixels have larger full well capacity, they also have higher read noise. But at image level, which is the only relavent thing in the photos, the DR advantage tends to go to finer pixel pitches (even when all other things are equal).Indeed. Adding more pixels is at the moment a simple and clear way of increasing DR.
At lower ISOs, yes, so for many sensors (Caaaanon) it is necessary for us to study the behavior of the pixels at higher ISOs.

DR has nothing to do with pixel size.

Explain, with particular reference to the relationship between read noise and charge/voltage conversion factor (gain) and in turn, the dependency of that upon capacitance.

You care if you want to post-process and adjust the tonal curve globally or locally to be able to lift detail out of the shadows. The printer can print and display the post-processed picture, but if the data isn't there in the first place then no amount of post-processing will help.
Thanks for the link, interesting read.
The score is a bit lower than some were obviously hoping for but I still think we will see great results from this camera.
The scores are a little bit better than my 'legendary' Nikon D40 (albeit 5 years old) I'm sure many people will be happy with something as good as that in this much more compact and discrete format !

I don't expect the G1 X is going to be the answer to all our prayers on here. But for day to day use I think it will get the job done. And if the price drops to even $699.00 it will help.
I don't want cameras anymore where I have to buy 3 lenses that cost more than the body each, or carry them. I know this is not going to be a great sports camera etc. But I want a camera that I can throw in the glovebox, take with me around town on a bike or motorcycle, on foot and just take shots. That is what it is all about.
The average person on here is never going to be a Pro Photographer or work for National Geographic etc. I know and you know this camera will probably take very good pictures of most of the things the average person shoots. And the price and form factor will be hard to beat, and you can probably let your wife use it and it will work for her also. Who doesn't want a Nikon D4 etc. but do we really need it.
Photography is suppose to be fun. Maybe even a challange using a less than ideal camera, but for the money this camera will be more than enough for most peoples needs. Save the money on lenses and take your family on a vacation to Disney World and take shots of them with the G1 X ,and just enjoy life. It goes pretty fast trust me.

Yes, as in a vessel of cow feces. If...if....if....if my grandmother had balls she'd be my grandfather.
Rather than being the worst kind of reductionist, how about absolutes in a conversation about empirical observations. When measuring the dynamic ranges of cameras those with sensors containing larger pixels tend to produce greater dynamic range at a given ISO rating. I suppose if you make DR a proportion of the total DR to the pixel size there are diminishing returns....I mean double the size of the pixel and you don't double the DR, but there's only so much we can expect from digital sensors at this point in history.
Anyway, blathering on about dynamic range is a fool's debate. The G1X is better in this regard than point and shoots with smaller sensors, but not as good as full frame sensors like the 5DMkII, exactly as it should be.

You mostly come over here to tout the X10. Just hang out over on that forum. BTW, Most people don't want white orbs in their images, period.
I have tried the alternatives - NEX-5N, Panny m4/3, etc. - and returned them quickly. I love using SLRs, but not willing to lug them and their lenses around. If it lives up to its potential, the G1 X will be what I'm looking for - a High Image Quality, carry anywhere, use with external flash, etc. shoot quick video, camera.

Agreed!!
Agreed!! Portable, great in low light, good DR, that's what I'm hoping for. For sports or action I use HD Video, not stills. I don't read SI, I watch ESPN!
Some do need and want the high-end APS-C or FF SLRs. I know how to use them, just don't want to deal with or pay for them. The G1X should definitely improve the images I shoot without me having to change my approach much. If the IQ lives up to potential, then when I do happen upon a great shot, I might be able to get a print good enough to enter a contest or two. If not, who cares?
Amen to that!! My wife and I took a great trip to Switzerland a couple of years ago. I used a Panny ZS3, good at the time but decidedly inferior now. When I showed the photos to our friends, they raved about them and asked me what kind of camera I used. I told them I had already sold it because I personally didn't like it. I also told them that learning how to take good pictures is WAAAAY more important than what camera you use....

And in terms of DR, the 5DMkII's full frame sensor is better than P&S sensors, but not as good as entry-level APS-C sensors like those in the Nikon D5100, Pentax K-r, or Sony NEX-C3, exactly as it has always been.

By your logic (in response to Jay_b), why not get the even more portable and cheaper fuji X10? DR is better than the G1X. It is also comparable in low light. By comparable I mean using its EXR binning mode, reducing the resolution to 6mp but improving the S/N score by about half a stop. Add 1 stop faster lens at the wide end and 2 stops at the long end and low light quality is about even. Factor in the faster operational speed of the X10, then I don't know why any rational person would choose the G1X except for emotional reasons.

The term "better" is thrown around like it means something. D5100 BETTER up until ISO 400 at which point the 5DMkII overtakes it in DR. And never better at noise....or tone....or color. Arguing these specs is so incredibly pointless. NEX-C3 marginally BETTER in DR at ISO 100, and worse after. And worse on tone....and color.....and noise across the board.
Choose one number from each of ten different cameras and say that those ten have better test results than one and I'll tell you what you've got: ten cameras in your backpack that are less useful than having just one that balances your needs. That's an expensive way to maximize your image quality.

Btw there is a firmware fix for the x10 orb problem

Or you can fill all your needs with one camera, the G1 X...then you'll just have one camera that clips highlights like an m43rds POS.

I'm going with a 2 camera approach. My 7D and a point and shoot that will most likely be the G1X. If I'm going to carry a bag with an SLR I'm not screwing around with a Sony or Nikon piece of garbage, especially not the small bodies (NEX or 1 series). If I'm going to carry something small I'm going to put a little belt holster on and take pictures that have similar quality to my 7D. Yay for me!!!!!
