p12: @Sekura, sure, the picture isn't great, only watercolour, but this is ISO5000!

@Cy, you are right, no shop will have so much similar models available, Sony should concentrate on lesser models.

A sample at ISO 1600 is obviously much more meaningful:

Sekura Drops: I was slightly hopeful about this camera that sony failed about pic quality big time in hx9v since it paints not takes photos even in base iso in some occasions, you expect them to change somethings. But after seeing this photo:

http://www.magezinepublishing.com/equipment/images/equipment/Cybershot-DSCHX20V-4063/highres/DSC00291_1330479450.jpg

I think how bad you can fail! Anyhow you can buy it for simplest p and s occasions with 20x reach. Still have to consider Panasonic FZ150 or wanna consider more compact body canon announced also new compact zooms that will certainly perform better than this in stills and not fail you too much for videos too.

But hey, that photo was shot at ISO 5000!
At ISO 1600 things get remarkably better, see here from the same source: http://www.magezinepublishing.com/equipment/images/equipment/Cybershot-DSCHX20V-4063/highres/DSC00292_1330479654.jpg

Well carried out experiment, kudos!

An oRbscure point remains to be checked, though… Fuji, on v1.03: “The image area with high brightness might be recorded as ‘black-out’ area, just in case of dedicated shooting condition, This unpleasant phenomenon is improved.”

This is the unpleasant phenomenon (2 independent sightings):

"Magnetproof" cards? For me, this is news... can magnetic fields really damage SD cards?

On CIPA starts to report growing mirrorless sales article (200 comments in total)
In reply to:

Jay A: It would be nice if some of the major manufacturers would begin to realize that it's not necessarily a love for something mirrorless that people like but rather a love for smaller, lighter systems. Years ago the market was dominated by cameras such as the FM2, OM1, AE1 and such. Then came the behemoths like the F4 and then the digital cameras. Why oh why doesn't someone like Canon produce a full frame digital the size of a Canon F1? Tell me they cannot do so and I will say that's a crock. I myself own a 5D MKII, Fuji X100 and Panasonic GH2. The 5D MKII rarely gets used anymore even though its picture quality is the best of the 3. Fact is I would just rather carry around something smaller and lighter. If Canon would replace the 5D MKII with something the size of a Canon F1, I would dump the X100 and GH2 in a heartbeat.

Caleido: I don't see it. Enlighten me. The thing is huge and has no strap. Obviously it needs big lens elements and a big cube as a "sensor". And yet it still only delivers 1 MP of resolution. It has no flash and low light performance is not good so I have read.

The time and effort you "win" by not focussing, you lose afterwards with fiddling through the different images. Parents using it for their children now have to chose which of their infant will be in focus or use different pictures. I did not hear them complaining about having everyone in focus with the big dof from the usual compacts cameras.

Unless they can put something together which has at least the size of a regular pocketable digicam and at least some resolution from beyond the 90ties, this is merely a niche gadget for very very early adopters.

I did see some potential for professional studio or macro photography when they announced it couple of months ago, but not with the toy with only two buttons we see now.

Well, Oct 19 was when DPR saw a mockup, but by then the announcement itself was already "a couple of months" old. (Hence my "baffling" little more than a couple.)

A little more than a coupla months ago, actually.

Does anyone know whether this G1X is meant to supersede the G12 or to coexist, as a "big sensor option", with a future G13/G14?

"Now, if it could be layered for color detection! Then we would get rid of the Bayer CFA filter also. But .. thats another story I assume."
Yup, and very sound to begin with. To the point that some folks invested heavily on the concept and it's currently implemented in some cameras -- I'd suggest you search this site for (Sigma's) Foveon sensor.

Maybe being aware of the existence of an unique sensor is different from being interested in it to the point of getting familiarized with the associated Hall of Fame...
Merry Christmas to you too, as well as to everyone else here!

Usee,
Thanks for the tip. I took Roland's words at face value ("now, if it could be layered for color detection"), and it didn't ocurred to me to first check his background -- as if he were a job applicant or something...

edu T: "The organic material's sensitivity to only visible light also avoids the need for a UV-filter in front of the sensor (silicon sensors are sensitive to UV light)."

Given the wavelength x output curve shown, didn't you mean "IR-filter" and "IR light" instead?

Go figure. Or ask them. That was a source referred to by yourself, hence yours truly believing it was reliable.

TOF guy:
Not to dispute who is wronger but, oddly enough, the same source you quoted shows the "typical silicon sensitivity" curve gently rolling off towards UV and zeroing a bit wee below 400 nm -- besides, as expectd, having a HUGE peak @ 1,050 nm or into near-IR. The graphics is at the bottom of this page, http://www.maxmax.com/camera_technical.htm .

Yep misterpepper but silicon sensors usually are INsensitive to UV (unlike film) and come with IR filters in front. Well, anyway the IR band is at the right side (>740 nm) of the axis.

Snaaks: Getting tired of all the meta-comments whether phones announcements should be in dppreview or not.
clearly smartphone-cameras and P&S cameras are converging so smartphone-news is also camera-news.

Adapt !, the world's changing.

Clearly some people from the "other side" also see this convergence; check this, "Nokia N8 vs. Samsung Pixon12 vs. Sony HX5v shootout: Blind test" -- http://www.gsmarena.com/nokia_n8_vs_samsung_pixon12_vs_sony_dsc_hx5v-review-519.php
