FTW: We will have at least the satisfaction that in any test we will not read anymore that the D600 or A99 make a better shot, it is the same sensor. Remains the absence of mirror, this can give it a serious advantage, the lenses can be used on the other brand with adapters too, so all plays on the mirror absence. But, I will not pay a surplus of 5000$ for that only. Bet all you want that NEX-7 with same lens makes the same good or even better shot. I have seen A99 and D600 shots. Up to 3200 Iso, A99 is cleaner and better than D600. Also the A99 body offers much more working comfort and the price difference is justified, it is an amazing piece of technology and D600 looks a bit poor compared to it. I do not compare this Leica to it, that would be waste of time. Starting by the price, all comment is useless. The day Leica sells it's cameras at a real value price, one can consider doing it.

Re:" If not Sony, bad high ISO. Sony sensor can produce rich color, which has been proven by Fuji X."

That's not a correct assessment!

Rather it's about the Sony column ADC that gives low shadow noise. Any CMOS sensor will provide advantages at high ISO over CCD, so that's not the discriminatory parameter.

Plastek: Let me guess: Sony sensor?

Not Sony, but CMOSIS!!

(This 24 MP, full 35 mm format sensor was designed and constructed in collaboration with CMOSIS especially for the camera and its use with M- and R-Lenses.)

On Samsung releases 12MP EX2F 'Smart Camera' news story (370 comments in total)

Great feature set of this new Samsung camera. If I remember correctly, Samsung recently started with compressed RAW, previously raw was uncompressed and made the camera slow in buffering/handling.

Good to see the progress with BSI-CMOS, this time reaching 1/1.7" size. Previous record was held by Fujifilm at 1/2" size. But how much better will BSI-CMOS in Samsung EX2F be compared to Canon's traditional FSI-CMOS in S100?

Interesting test comparison ahead to watch the sensor technology progress!

Does the new Canon sensor also use _nine rows of phase detection pixels_ to facilitate the Hybrid AF system like in the Aptina sensor of the Nikon's 1 System?

Posted on Jun 8, 2012 at 05:44 UTC as 94th comment

Canon has been playing a safe game with it's first pancake lens,
the EF40mm f/2.8 STM. Very similar to the famed Konica Hexanon AR 40 mm / F1.8 (http://www.buhla.de/Foto/Konica/Objektive/e40_18.html), while -1.27 stops slower, the aspherical lens certainly improves the wide open performance. The Canon pancake has a physical size of the also famed small Olympus Zuiko 40mm f/2.0 pancake, still containing a newly designed AF motor, labled STM.

Going wider pancake designs for the EF mount will be more complicated, but isn't impossible as illustrated by Samsung's 20mm f/2.8, Olympus' 17mm f/2.8 ans Panasonic's 14mm f/2.5. However these three lenses are for mirrorless camera designs, an area Canon still has not entered.

JordanAT: Man I hate pop-up flashes on compacts. There's little enough room for fingers as it is.

Does the RX100 internal flash work as a commander for wireless flash, like the XZ-1 does? If so, no problems with lacking a hotshoe.

Direct link | Posted on Jun 6, 2012 at 18:47 UTC

Is the sensor oversized a la Panasonic GH2/LXx, eg, keeping the sensor diagonal fixed for various aspect ratios?

Absolutic: will probably produce the best picture out of all compacts, and could be on the same level with M4/3 when pictures downsampled from 20MP to 12 or 16MP.

Re: issues with dust

-What will you do with sensor dust on your fixed lens camera? It will show up sooner or later, like it does on the present 1/1.7" sensor luxury compacts. None to my knowledge are using ultrasonic filterings on a P&S.

-On a CSC, you can yourself remove the lens and even do a wet cleaning of the sensor if absolute necessay.

But I do agree with portability, that's the reason for the popularity of the LX5, XZ-1, S90/S95 cameras in the past. RX100 definitely runs to the top of this group.

Combatmedic870: 1/2000th of a second shutter speed kills me!....why! 1/4000th is truly more useable!

Looked over at Imaging Resource, Sony RX100 Technical Info, but couldn't see mentioning of a ND filter. Haven't seen a filter thread or adapter for the Sony RX100 either. Don't know the smallest aperture it uses, f/11 perhaps?

CameraLabTester: Well done market research and ergonomic design by Sony.

This was how the Nikon 1 should have been, but they blew it.

.

Not necessarily, still the Nikon 1 can put this Sony sensor in, and they're on the same field.

Nikon 1 can add support for external flash, but I haven't seen if the RX100 can act as a controller for remote flash.
Nikon has a pancake, but not yet a foldable zoom.

Actually, time will tell, which one sells most.

Hardly on a leaf shutter in a P&S camera.
Use ND fiilter, like all P&S have already integrated, for the sake of reducing diffraction problmes.

Jefftan: Although sensor is much smaller than NEX (about 1/3 size) it is:

BSI CMOS

and the NEX sensor is not.
May help overcome some IQ loss to sensor size

Re: Look at the DPR preview .. it says BSI sensor
It's most likely a typo!
Haven't seen any mentioning in the Sony press release about BSI-CMOS, so it's probably not.

With the access to both bright primes and new bright zoom lenses, remember the MFT has 1EV better theoretical performance to start with.

BSI-CMOS, where did you get that from???

No BSI-CMOS seen larger than 1/2", and that's from Fujifilm with their "EXR-CMOS" Sensor!!!

Direct link | Posted on Jun 6, 2012 at 05:56 UTC

The focal magnification factor is 2.73x and the pixel size is 2.4µm, compared to 3.4µm for the Aptina sensor in Nikon 1 System.

It's also a Sony CMOS Sensor "Exmor", using the "Column-Parallel A/D Conversion Technique", which will put the Canon G1X to shame, having Canon's in comparison somewhat outdated sensor technology.

The teorethical performance difference between Sony RX100 and Canon G1X is 1.17EV. The brighter (f/1.8-f/4.9) Zeiss lens of the Sony, compared to the slower (F2.8-5.8) in Canon G1X, alone leverages the performance handicap with respect to the sensor size. (Canon's f/2.8 isn't better than f/1.9 in Sony's equivalent.)

Additionally, with Sony's anticipated better sensor technology, both better read out noise and better dynamic range, this camera seems like a winner.

trevmar: From the upgrade notes:

** "MOTION PICTURES CANNOT BE RECORDED" **

Panasonic used to be at the top of the heap for movie recording with P&S cameras. This, and the 30 minute FullHD limitation, have me looking elsewhere.

I can't believe Panny would throw away their lead in video technologies..

Wireless streaming Full HD video would empty the battery of the FX90, long before you even were able to shout your "I can't believe..."
Have you seen the battery draining effect of the current camera integrated GPS receivers? And those are not transmitters, which you would require in a camera for WiFi.

ogl: 150/3.6 equivalent of 135 format for 900 USD. Hmmm.

I don't think that 150 mm is PORTRAITS distance.

Actually the Zuiko Digital ED 50mm/F2.0 Macro together with the EC-14 TeleConverter has been a popular portrait combo.

Guess what? 50mm x 1.4 = 70mm

Probably the upcoming 60mm/F2.8 Macro pushed this lens up from 70mm to 75mm.

In reply to:

bradleyg5: This is getting absurd dpreview you should be ashamed.

This listing the focal length "equivalence" right next to unadjusted aperture is border line disingenuous.

It is not a f1.8 150mm "equivalent" lens, it is and forever will be a 75mm lens, it doesn't magically become a 150mm lens just because you put it on a camera with a small sensor.

If you insist on listing "equivalent" figures, list the equivalent aperture right next to it so people don't get the wrong impression.

This lens at f1.8 75mm will produce an image on a micro four thirds camera that will look identical to a F3.5 150mm on a full frame camera, for you to imply it will look like f1.8 150mm is flat out wrong and shameful.

The equivalent field-of-view listing is a common nomenclature, used along the whole range of cameras from compact to APS-C.

Evereyone understands its use, a common and well understood practise.
