GeorgeZ: Great, the last HX series delivered pics as mushy as I've not seen in a long time, even at base ISO. Now we have more MP, same size sensor and even longer lens. Reduced to 6MP, these pics will be ok for many ppl, but this market segment obviously isn't beyond the MP race yet.

The popular belief says images from old, low MP digicams, provided superior IQ compared to current, high MP sensors.

It just not true ! Images from HX20 downsampled to 6MP would destroy output from any of the old 6MP cameras at any ISO.

This is mostly due to the fact that cameras with 6 million native photosites have to be demosaiced to produce RGB output - a process that involves interpolation.

marike6: Making a DSLR smaller doesn't make it more usable. Chopping off the grip may appeal to m43 fans, who seem to believe that ALL cameras should be miniature because it's just too hard, too much effort to carry a normal sized camera, but it won't make the camera easier to shoot with, or balance better with telephoto lenses. It is much, much more tiring to shoot with a camera that has no grip. So I'm hoping this trend towards miniaturization ends soon.

As far as the sensor, it's strange that Nikon used the 16 mp Exmor in the D7000/D5100 for one release cycle and it was class leading for DR, color depth and ISO. Canon has this mediocre 18 mp sensor and they are using it over, and over, and over again. Go figure.

All that said, this camera actually looks pretty interesting, and at least it has a nice LCD and an OVF. If it had a slightly better sensor, it would be more compelling.

There *are* m43 cameras with a grip.

Well, I am not surprised at all ! The appearance of bizzare, halfcrippled, monstruous creatures like EOS M, 700D and 100D correlates well with general impression left by this interview: http://www.dpreview.com/articles/0336328811/cp-2013-interview-with-canons-masaya-maeda

It all speaks a clear message that boils down to single word: cluelessness.

It's hard to believe it is the same company that designed the 10D-40D line of cameras.

facedodge: Some websites are speculating that this is a NEW 18MP SENSOR.... no change in number of pixels, but a change in ISO performance. ISO range is now 100-12800 native - expandable to 25600. That is a one stop increase.

Maybe it's more noise reduction. We won't know until we get to test it.

Well, Canon is actually quite good performer in terms of general (midtone) high-ISO noise levels.

Rather, it's a deep shadows noise (and implied DR) that is 2009-ish.

Sdaniella: nothing wrong with padding filler models on the LOW END eco-budget lines, that's where the volume sales aimed at beginners predominate.

no need for 'lead innovations' whatsoever on these models, but the odd one now and then; so 'carry over' or 'trickle-down' features from higher models more likely than having 'exclusive innovations' in abundance on the lowest and thus cheapest models.

detractors should get over it; this isn't a new practice for any mfr; they all do it.

sdyue

It's just that other manufacturers (Nikon, Sony, Olympus) have made enormous progress in sensor performance (in terms of DR mostly) since 2009; and this progress has transpired into their entry-level modellines as well.

Canon has made no such progress in 4 years now. Currently this technological lag translates to 14Ev (Sony, Nikon) versus 11Ev (Canon) of DR.

And it has serious implications even for JPEG shooters: the in-camera DR expansion modes (DRO, ADL) work much better with 14Ev sensors than with 11Ev sensor.

Rachotilko: Hopefully for Canon (but also for their vendor-locked-in customers) this performs much better in terms of noise floor - ie. the dynamic range - than 650D. In case is does not (and this seems likely), then their trailing behind the competition is truely woeful. But maybe Canon thinks we don't need shadow details @ low ISO.

@ZAnton:

well, RAW is not the whole story. Sensors with low noise floor give manufacturers more freedom when implementing the various tonecurve (aka "DR-expansion") tricks (such as Nikon's ADL, Canons HTP, Sony's DRO, etc) in JPEG engine.

This feels like they admit the EOS M did not do it. So they try to fight M43 from different direction.

RAW is great, no doubt about that. However, Panasonic should work hard on improving their NR algorithms.

Rachotilko: f/1.8-f/5.6 ? I'm no Olympus fan, but XZ-10 will destroy it in low-light, despite the smaller sensor.

But for me, having f/2.7 @ 140mm eq is much more attractive than 50% larger sensor. The number f/5.6 is so unpleasant to read and think of.

Ad "smallest of the small": well, pocketability is the main point of both P330 & XZ-10. If the strict pocketability is not a hard constraint, then there are multiple options (P7700, MX-1, XZ-2, X10, X20, EX2F ...)

And then there is RX100

Timmbits: hmmm...
LOVE the image...

but on a humorous note, I don't know which is worse:
wearing nylons in a field, or running with scissors. ;-)

Ido love the pic though. ;)

@Vittorio:

In that case I have to say, that we admire here not only a good work done by the photographer, but nature's masterpiece as well.

In reply to:

shaocaholica: Resetting a photosite mid exposure is still 2 exposures.

But not all of them at the same time ! That's the trick ...

- in conventional sensor, there is one readout time

- in Fuji EXR, there are two different readouts for two groups of the sensor pixels.

- in this Rambus tech, each pixel is reset when it needs it. Much more efficient use of the sensor area than the Fuji approach

Direct link | Posted on Feb 27, 2013 at 16:37 UTC

I won't criticize it since I don't understand the details. However, I do have some superficial hypothetical opinions regarding the idea.

1, From the short description it seems as if it actually choses to overexpose and takes care of the overexposed pixels via their resetting mechanism.

2, It sounds as a smarter version of Fujifilm EXR mechanism. Similarly as in the case of EXR sensor, one group of the pixels is used for capturing the shadows, the other group is used for capturing the highlights. But in the case of the EXR, membership of a pixel to either group is predetermined (the well known EXR pixel layout), while in case of the Rambus' BinaryPixel technology the membership is decided based on the actual exposure process taking place.

3, Practice has shown that EXR approach works in expanding the DR, but some sensor area is actually wasted. The Rambus technology essentially means you'll get the benefits of EXR without the infamous EXR drop in resolution.

In reply to:

Hugo808: So the advertising department gets to say it's a sharper camera because of the lack of an OLPF, which you wont notice unless you blow your pics up to 6 foot wide.

But no OLPF means you might get moire which ruins your pics permanently (no matter what they say). Are we supposed to be happy about this? I've waited ages to upgrade my D90 but I am not going to risk moire as I shoot a lot of weddings. You can hardly ask the bride to remove her veil because Nikon can't make a decent camera any more.

I think photographers should be put back in charge of camera design at Nikon. Or at least give us a D7100e which has the OLPF put back where it's supposed to be!

The fact is that with resolutions this high the risk of moire is almost negligible.

But you're right: weddings are a special case because of the veils.

Rachotilko: I don't understand people complaining over the sensor size, when it's actually IQ that matters.

Of course, IQ depends on sensor size, but it is not the only parameter determinig it. There is the technological advancement thing, which many forget about.

This device beats Olympus XZ-1 in IQ, and yet XZ-1 was such a spectacular success. I don't see why XZ-10 should be priced any less than the XZ-1 was.

@marike6:

There are however very good reasons to believe the sensor will be significantly better on XZ-10 than on XZ-1.

About the lens: yes, I think the lens will perform the same.

The DOF control on sub-1" devices ? C'mon ! Maybe for close-ups.

SX50 beating XZ-1 is no speculation, but the hard numbers. See DxOMark.

Regarding XZ-10: Yes, it's speculation, but given the current state of the technology and the market, the opposite outcome will be very unlikely.

Best 1/2.3" sensor of today (Canon SX50) beats XZ-1 hands down. There's no reason for XZ-10 to do any worse, when in fact both Canon and Olympus use Sony P&S sensors these days.
