On Sony Cyber-shot DSC-RX10 Review preview (482 comments in total)

The video resolution is insane. It also shows even GH3 only has about 720p true resolution even though its aliasing is still better than the rest...

Oh! Good... Will Adobe make Panasonic profiles?

No phase detection?

0MitchAG: This just goes to show the u4/3 Panasonic-Leica is way overpriced! Isn't it silly that a Panasonic lens should cost more than this, on a smaller system? By all means the PL is great, but I'm sure glad I didn't pay the asking price.

I don't know about the PL45 but the PL25 is really just an OK lens for an OK price. Nothing Leica about it.

gerard boulanger: Fuji 60 mm macro f/2.4: $600
Zeiss 50 mm macro f/2.8: $1,000
Assuming they give comparable experience and IQ, this is very unusual to see a non original lens 66% more expensive than the original brand name.
To me, it makes sense only if performance and IQ are way better than the Fuji one.
Zeiss magnification is 1:1, much better than Fuji, does that justifies the extra money?

Sigma is one thing, Zeiss is another. Now Sigma is trying to move up the ladder...

Now even APSc is getting F/2 zoom...

In reply to:

chaos215bar2: It would be nice if you could post just one article for new product launches, so all the comments ended up in the same place. Three is a little ridiculous (though I realize each one is technically something different).

That would be against "clicks".

In reply to:

Gao Gao: It seems PDAF is not used during movie recording?

Pity but given that they still only offer 30fps and 24mbps (hopefully at least the codec does a better job at motion prediction), PDAF in movie probably isn't high on priority list.

In reply to:

Raist3d: "Ultimately, despite its authentically semi-pro appearance, the E-M1 is still a pretty small camera, if compared to DSLRs. The disadvantage the previous top-end E-series cameras had was that they ended up being as big as any other DSLR (the E-3 and E-5 were essentially the same size as a full-frame DSLR, at which point it became hard not to measure it against those cameras). The E-M1 may be large for a Micro Four Thirds camera, but it's not big in the grand scheme of things."

SPOT ON. Been saying this for years now :-)

And we are already seeing pocket-able cameras with larger sensors. I wonder whether or when Canon is going to make an EOS-M with 35mm sensor and Dual-Pixel CMOS PDAF.

In reply to:

Sergey Borachev: I think this booster does more for NEX than for M43 as it does not provide any wider FOV. It can provide more lens speed, which would make fast FF lenses even faster and that sounds good for re-using legacy lenses which are cheap and fast. However given the ghosting or flare issues when using those lenses on M43 cameras, I also wonder how good the end result will be with such speed boosting. Lots of question marks here. Are there independent tests yet?

They should make a 2x booster with 4x ND built in

On P2010255 photo in dpreview review samples's photo gallery (6 comments in total)
In reply to:

Philly: backfocus? Was focus on face? The face looks soft, but the orange "350" sign in the back left side looks sharper. For a f4.0 1/80 shot, I would have expected a better technical performance from this lens. I'm not sure why dpreview would post this shot unless it is a representative shot--in which case, it is rather disappointing, in my opinion.

Zoom in and you you'll see the focus is right on the face. However, perceived acuity depends on the contrast between foreground and background.

The orange 350 looks sharper because it has white outlines surrounding the black text.

In reply to:

FTW: The real deal was to sell NEX-7 the way it is with Hassie logo on it, put a wonderful lens on it and sell it at same price as Sony. That is the way to make business. If you buy a chinese lens, you don't care if it is marked Samyang or Rokinon, you buy it for what it is and what it does. A NEX-7 form Hassie with different rubber grip colors and glue that sticks on the grip, a rubber that you don not lose after a month would be a bargain. Sony's NEX-7 grip rubber sucks.

I thought Samyang was Korean.

In reply to:

lajka: What real shallow DOF? Remember that because of the format MTF lenses have DOF two stops down compared with FF. Thus 1.8 on MTF is 3.5 on FF. You would be better of with FF Zuiko 100/2.

on m4/3? that's a 200/4 without AF.

REDred Photo: My favorite street lens has always been the 35mm. I really would love to see a 17mm f1.4 in a fairly small form factor for micro 4/3.

20/1.7 is tiny, though

weput: I've allways had a position on the mirror/no mirror thing.... as an engineer i tougth about putting the sensor directly to feed the liveview screen as a doable thing.... even removing the shutter as the image could be captured electronically

virtually no moving parts inside the camara
virtually unlimited time of service for the device... and given the speed and capabilities of chips nowdays.. (imagine a quadcore qualcom inside one of this things)...

however... sometimes i'm just an idiot dreaming...

flipmac - Nikon 1 has a rolling electronic shutter. Most P&S cameras use in-lens leaf shutters.

ericsan: Canon slow innovation makes me keep my 550D/T2i still for a while and rather invest in the coming Canon mirrorless body if it's worth or Olympus EM-5 which is so far the best mirorrless product ever !!

They don't expect users to upgrade every iteration.
