Thanks, I'll stick to my punch cards.

Wubslin: Does it come with a rootkit installed

No, but it has a warranty.

mjw3: Most people have never heard a gun fire apparently.

Nobody can identify a gun discharge based on a single bang from something like a firecracker. Guns all sound different and nobody has heard them all. Now if there is a gunfight going on, you probably can identify it by a distinctive pattern of shots that wouldnt resemble firecrackers or backfires unless the firecrackers were set up to sound like a gunfight.

AbrasiveReducer: Once you use a camera with pixel shift, you realize almost nothing in the world holds perfectly still. And you sacrifice the instant feedback you get with a digital camera because a lot of these tiny movements will not be noticed at the time you take the shot. I found it was a bit like shooting film; you're never 100% sure nothing went wrong until you see the finished result.

Yes, if the camera takes one normal image along with the images that are pixel shifted, you should be able to use software to merge the pixel-shifted RAW with the normal photo to replace the motion-corrupted areas and get the best of both worlds. Of course, if the software isnt up to it because there is too much motion, then you always have the normal photo to fall back on.

Iliah Borg: Gentlemen:

The Studio Scene link for 7R3 pixel shift leads to DSC00234.ARW, which looks like an ordinary uncompressed 14-bit Bayer raw, no signs of pixel shift. Shouldn't there be three more raw files / data sets to form a pixel-shifted version?

Does the software that merges the pixel-shifted images produce a single raw image from the four original raws or a DNG?

Kraaketaer: It seems the pixel shift either accentuates chromatic aberrations or introduces some kind of fringing with high contrast lines: look at the fan-shaped paintbrushes or the strands of hair below the ears on the top left model, not to mention the crosshatch patterns in the corners.

Okay, the lens change would easily explain the purple fringing. Pixel shift cant undo lens aberrations.

If that is the case, it leads me to think maybe they didnt actually use pixel shift in the image we are viewing that says it used pixel shift.

Yeah, there is some serious purple fringing on the chrome metal handles of those fan-shaped brushes that is not present in any of the other camera's images.

Marcin 3M: Sony will soon produce a sensor that will outresolve even Nikon and Canon lenses.

Dont mean to answer for nekrosoft13, but "resolve higher resolution" sounds a bit redundant. I think you are right that lenses dont have a "resolution" in the sense that the camera's sensor does though, so "resolution" may not be the correct word considering it is generally use about a sensor. Maybe "resolving power" or "projection quality" -- after all, the lens is just projecting an image on the sensor and it is the quality of this analog projection which is digitized by the sensor.

Albert Valentino: Interesting that the “Sony” sample image is essentially a static composition so no motion blur can occur over the time from first to last capture. Yet, the article other day about the high resolution pixel shift mode of the “Panasonic” G9 was all about moving elements which resulted in blurred area and artifacts. Apple and Oranges articles which make on brand look great and the other a bit flawed

No doubt about it, you can see motion blur or some kind of pixelation on objects that moved in the pixel shifted photo. Just look in the windows of the building on the right at people working. So right now, it is a balance of what you want in your photos -- better detail on fixed objects or worse detail on moving objects.

One would think processing might help -- could there be any way software could detect the motion effects and counteract it in those areas? I imagine it would be tough because the motion could be in any direction at any speed -- it would be like trying to put humpty dumpty back together again.

mpb002: While the body is smaller than conventional FF DSLRs, by the look of thise photos, the advantage of the smaller camera body is rather mute when a big lens is attached as shown here. Sorry Sony, I will stick with my 5DIV. I dont think the ergonomics can be beat. It fits my hand like a glove. But I do understand why others may prefer the smaller size of the Sony when fitted with small prime lenses.

Well, I think camera bag fit is an often overlooked advantage of a smaller body. Sure, you could always buy a bigger camera bag. But lets face it, whatever camera bag you choose to use on any particular day, if one of your camera bodies (or both of them) is smaller, it means you might be able to use a smaller bag or add another lens to the bag you wish to bring.

Amnon G: Did you notice the weird texture in the left eye of the model in the 3rd image? Looks very processed.
Also look at the right eye in photo #6.
I have never seen humans with patterns like this.

So this is over processing or we found the way to identify replicants ;-P

Simulant! Skin job.

Charrick1: Sony...this camera is pretty cool. But don't throw your less wealthy potential customers under the bus. The a7ii came out months before the a7rii, yet the a7riii has come out before the a7iii. I am waiting for the a7iii, and I HOPE that it will still come out, as there needs to be some good competition at the lower end of the full-frame scale. A sub-$2,000 a7iii needs to be made...but now I'm worried. Well, if it does come out, hopefully we will get something for our waiting, namely a camera that, while having 24 megapixels (my current sweet spot), will also have many features of this camera (especially the improved focusing), just as this camera has some features from the more expensive a9, which came out earlier.

Well, both Nikon and Canon have their new $3k+ FF cameras out. I think Sony felt it was being left out of the party. I dont think Sony is worried about the Canon 6d2, and the D750 is a bit long in the tooth. So, until there is serious competition for the current a7ii, there is little incentive to release the a7iii.

Wonder if my tongue would work on the touchpad.

Lawn Lends: Touchpad AF, nice for lightweight lenses. But if there was only some way to put a remote wired touchpad on a grip attached to the tripod collar mount on a longer lens.

Originally I was discussing a wired touchpad to attach to a heavy long lens, this should eliminate lag caused by a wifi or BT connection of a cell phone.

@meanwhile That's a good idea. In fact, I have an old android cell phone that would be about the right size. I could screw some kind of grip into the tripod collar that would allow my left hand to support the weight of the lens and leave my thumb free to pick a focus point. Of course that would mean removing my hand from the grip to zoom the lens. While my hand is on the zoom ring, i would just have to pick the focus point with the build in joystick.

Georgeee: This is what I like about Sony. It keeps innovating and does not hesitate to put all it has into the next product. This version addresses most of the concerns of the II. As a Canon user for long time, I am very impressed. In fact, I have bought a II 2 months ago and like the IQ a lot, despite all others minor issues. This one plus the 24-105mm f4 (assuming great IQ) may trigger me to completely switch over.

But have you seen the price of the 24-70 f2.8? Yikes. Canonites are a bit spoiled when it comes to nice glass.

princecody: You walk into a bar and see this new Sony & a Nikon D850 next to each other-which one do you pickup? The sign says grab one 😀

The Sony, but only because I can adapt it to my EF lenses.

Link | Posted on Oct 25, 2017 at 19:24 UTC

Now, let's see tests with an EF adapter like the Metabones.
