But does the shutter still make a loud "clack"?

pew pew: I suspect this camera will blow the dxo sensor stats.

@Shamael: considering that the D700 sensor is not even video capable, why would you conclude that a 4k video recording sensor is a "reworked" version of what is now an ancient (albeit great) sensor, just because it has the same resolution?

siggo: Umm Sony, could you PLEASE do this for A7R???

Sony provides the EFC feature on every sensor that is capable of it, AFAIK. The A7R sensor simply doesn't support it. The A7 does.

On Leica T (Typ 701) First Impressions Review preview (2305 comments in total)

There is a lot to like here, though it looks to me that its outstanding features and details won't necessarily add up to produce a great camera.

The solid body, the beautiful twin wheels, the most attractive add-on EVF I have ever seen, the touch screen interface, the new mount -- they all look fabulous. The elimination of the lugs is especially fantastic, in my opinion.

However, I think a camera really does still need more real buttons--much more so than a phone.

aqasem: What if it has,
5-axis OIS
Global shutter
Fully articulated screen
in camera 4K
Hybrid AF
same size and around $2000

What if we all grow wings and fly away?

M DeNero: Another compromised Sony niche product digging Sony a little deeper.

"Niche product" and "compromised" are mutually exclusive. Do you mean to say Sony hasn't hit the niche they defined, or are you just unhappy with their definition of the niche?

tanniewu: Waiting to have this update to my E-P5 and E-M5! Although, I didn't see it as much an issue to me... luckily perhaps :P

If this were fixible in the E-P5 you would think it would have been updated first, since DPReview slammed the E-P5 for shutter shock issues.

Ben Raven: HELLO, SONY -- A7r Electronic First Curtain Update !
PRONTO !

Get on this same EFC shutter firmware update for the A7r.
You've already got it in the A7 . . .

Let us say 'Ba-Bye' to shutter shock and clunk-clunk.

Thank you for your prompt attention.

Sony said when it came out that the A7r doesn't have EFC because the A7r sensor is not EFC capable. Evidently the E-M1 had a previously unexploited EFC capability that it is now addressing in firmware.

They make Zeiss lenses as well as their own branded lenses.

On Sony Alpha 7R Review preview (808 comments in total)

I think a couple of the Cons in the conclusion are a little silly, and a couple legitimate defects should be mentioned in their place namely:

No in-camera Raw conversion -- It's cute that some cameras offer it, but is the camera such a sensible tool for doing raw conversions?

Limited selection of FE lenses -- a brand new system is introduced with some stellar lenses. How many lenses should any manufacturer have ready at launch for a new camera?

Missing cons (mentioned in the review proper) are the loud and extended shutter sound (however fond of it you became) and the lack of a lossless raw file output option that would do even better justice to the sensor in some cases.

G Sciorio: Small body with a larger sensor means larger lenses. If the majority of the weight and bulk is in the optics...and if there are so few native lenses I don't see any major advantage over a DSLR.

Depends on the lens. I have tiny Contax G lenses. The 90mm f/2.8, 45mm f/2 have no issues with this camera. My tiny 21mm and 28mm are problematic, but for some applications they may still worth be using. I could go out with all four of those lenses together in my jacket pockets if I chose.

In reply to:

Tord S Eriksson: I seem to recall that the shutter in the A7 shook the camera quite a bit, and the one in the A7R was worse?! In my book that would be a huge con, no matter which camera we're speaking about.

Not a mention in the Con list — has the shutter noise/shake been eliminated, or what?!

@Tord, the A7 has an electronic front curtain option. It is enabled by default, but if it is turned off, then the shutter should be about the same as on the A7r. If turned on, it should click only once rather than twice, without potential to shake the camera just as the exposure begins.

SalmanH: Wonderful, nine photos and not a single one holding the camera the way it should be held, which I think is what many of us are most curious about with such a weirdly shaped camera.

I think that might be the whole point! How exactly does one hold it "properly"? If nothing else, it does look beautiful.

In reply to:

jennyrae: my opinion with Quattro sensor is put correct and optimal ratio amount of specific color pixel to achieve best picture quality. downside of equal amount of color pixel number per layer is the occurrence of red and green cast on pictures. I think I know understand why reduced number of reds and green. if theory is correct, color cast problem of foveon is improved or solved and also increased in luminosity means higher resolution in pictures with great color gradation. best of both worlds. high iso performance and faster processing are icing. can prove best Foveon camera from Sigma.

@jennyrae there is no reason to think this design will do anything for red or green cast. It simply produces a slight but measurable noise improvement, requires much less storage to speed processing (and maybe improve power consumption), and provides a small luminance resolution bump that might help compensate for the chroma resolution loss.

Joerg V: The blue layer of the Foveon actually doesn't capture saturated blue but a very very pale blue - almost white. So this is more like a sensor that captures white light at every photo pixel and color information with lower resolution. This seems like a more Bayerish approach and will probably sacrifice resolution but should help a lot with the Foveon noise that stems from crosstalk between the layers.

The camera design is... errr... special.

@peevee1 The picture is intended for laymen to understand. The layers are White, Yellow and Red (not Magenta). If the top layer were filtered blue, no red or green light would penetrate to the next level. So the top layer is unfiltered (not counting any UV-IR cut filter in front of sensor). Then there is yellow filter, then another sensing layer, then a red filter, and then the bottom sensing layer.

Blue values are derived from White-Yellow.
Green values are derived from Yellow-Red.
Red values are captured as is.

Ulfric M Douglas: The body is one BIG THUMB-GRIP,
which might be good.
Shame they changed the sensor : the ONE advantage they have over other large-sensor compacts.

The thumb doesn't do any of the gripping here. It is the palm. The thumb is free for pressing buttons.

In reply to:

peevee1: They should have higher resolution in Green, not in blue. Only about 5% of cones in our eyes are responsive to blue light. We are adopted to see detail in green foliage, not in a blue sky.

Since the top layer is monochrome you are getting the full resolution for luminance. Roughly 60-70% of luminance can be found in the green channel, but this captures 100% of the luminance at full resolution. Thinking of the top layer as "blue" is just a mistake.

qwertyasdf: 20+4.9+4.9 = 39? I don't get it!

If the grip is facing backwards, then the thumb needs to exert pressure to hold the camera. How can i use my thumb to press the buttons on the back?
I just tried holding my Canon 1D backwards, it dropped on the ground.
(But the scrollwheel, which is now in the front is very convenient for the index finger to turn)
Am I holding it wrong? I don't get it

Anyways, I'm gonna get it no matter what! ByeBye DP2M

You are missing the point of the grip. It is the overall width of the grip that gives you a grasp. Your thumb isn't needed to support the camera at all--your palm does that. Instead the buttons are at a comfortable distance from your thumb while it is naturally extended forwards towards the camera buttons.

There is no blue layer in a foveon. The top layer has no color filter. The middle layer is yellow, the bottom layer is red.

In reply to:

mikesco: While I agree that integrity of an image is important, in this case I see no difference from the function of cropping and cloning, it is simply the removal of unrelated content. Cropping in some situations could do a lot more to remove context from a photo than the cropping did in this case.

@forpetessake, what is it about the presence of two cameras that makes it more of a staged event than the presence of one camera?
