Dimit: Uncompressed 14 bit raw ???No thanks...no need for 100 MB files for something won't even notice in 90% of the cases..
More bits don't capture a wider range of light. The photosites get saturated at the same amount of light, regardless of the bit depth. More bits allow us to push the image more in post processing without posterization, but there are physical limitations. Noise in the shadow is still noise, no matter how many bits we use to capture it. If we had 32 bits, we would use it to capture the same noise more accurately. It's like measuring voltage to 8 decimals, when we know the accuracy is only +/- 0.1. All those extra digits contain no information.
The compression problem in Sony is not about bits, but ruining 16 or more consecutive pixels in a row if the dynamic range is too big.
Everlast66: I am actually surprised that people are surprised by this announcement.The A7R II has been rumoured for more than 6 moths and (according to rumours) postponed couple of times.
All improvements are logical and address things that A7R has been criticized for, others already added in A7 II, so most logical thing was to expect them in A7R II.
For the last year I have been saying that Canon/Nikon have 2 years to react in a categorical way to mirror-less technology growth, usually met with disagreement. At least now they will be forced to respond and show their cards, they have a year left.
Imagine 6 moths from now all this technology and more in a "pro" body - A99 II .Also about the same time an update to the very successful A6000.Perhaps an A7S II in 18 months from now, or even A99S version.
All of a sudden things look very different when these devices become fact and Canon/Nikon will find themselves on a downward slope with a mountain of tech to catch up, like Nokia in 2007!
The A7II only added IBIS, and ever so slightly improved AF. It looks like the A7rII does a lot more.
bluevellet: Watching the Camera Store review, it's hard to get excited about this camera.
It's not a super exciting new flagship, but an inexpensive model that gets very close to the X-T1 v4's feature set. Professionals don't get really excited by small, affordable cameras with built-in flash. On top of that, the 1-second buffer is very small for action. But otherwise it's a mini X-T1.
Rob Sims: I get the concept (small in size, big in image quality), but would it really have killed them to put a mode dial on and an extra control wheel?
Those two things alone would have made this a much easier camera to change settings.
Instead of a mode dial, I'd rather have a multi-purpose dial (ideally a programmable one). It's true that consumers don't change many settings, but serious photographs have a need for a small camera, too. Sony is actually not that bad, you can adjust most settings with a button press, followed by the rotation of the wheel. I wish the A5100 had one more wheel, but I'm pretty sure it's completely packed inside already. The A6000 is a better choice for those who need a viewfinder, more direct controls and wireless flash control.
Jogger: With touchscreen on real cameras, you either go all touch or no-touch. The in-between creates a lot of headaches in practical use.. esp. with a built-in EVF. Commenters crying about lack of touchscreen have no intention on buying Sony in the first place.
I think touch focus makes sense. It can be faster than pressing a button 12 times, and more intuitive, too. Yes, it means you have to remove your eyes from the viewfinder, but this is not a professional sports camera anyway.
JackM: This contradicts the raison d'etre of the X100.
If I want 50mm I'll just carry my 5D3 with 50/1.4. It will be about as portable, and much faster. Don't most X100 owners also have a DSLR or some other system camera? Or I'll crop, or move forward.
I'm not sure why one would buy a camera for "DSLR quality in your pocket" only to then make it un-pocketable.
I'd rather put the money towards another camera.
It's still a very tiny package, with leaf shutter and an optical viewfinder.
mannes: exactly the same law applies in Austria. according to the personal data protection law, you have to get the consent of the people that show up in your photo or film, or make their faces unrecognisable.
one consequence is that dashcams are forbidden in this country...
In Germany you can take pictures, you just can't publish them without permission. The new law in Hungary doesn't even allow you to take the picture, without PRIOR PERMISSION. That's a big difference.
Your translation isn't accurate. There are two exceptions: a crowd of people, and public figures (such as celebrities and elected politicians). However, it is not clear how many people are considered a crowd, and how famous or notable one has to be to qualify as a public figure.
Either way, no more candid shots can be taken in Hungary, even if they would consent afterwards, the photographer would be breaking the law, because the permission is required before taking the picture.
Lucas_: "World’s fastest AF of 0.08 seconds" - does that include DSLR's or is it among mirrorless? How does it compares with Sony's A7/7R?
Except they now have predictive AF tracking in the center 9 sensors, which can really track some action. But I don't believe it's the fastest, until independent reviewers confirm it. Besides, Fuji says it's the fastest ASP-C mirrorless, so that automatically excludes Olympus, Nikon 1, which are proven to be significantly faster.
This is the way a camera should be controlled.
Shutterspeed, aperture ... and ISO.
The three primary parameters of exposure.
Why did it take this long for camera makers to ditch PASM, and place ISO alongside shutter speed and aperture? This is much simpler and straight forward.
Thank you Fujifilm!This will be my next camera.
Also the Q (quick) menu is unbelievably handy for the secondary parameters, such as dynamic range, white balance, sharpening, contrast. It's an array of the most important settings, only a button press away. Meanwhile other manufacturers keep mixing format card, date/time, language, folder name and beep with ISO and white balance. Why?? Also, wasting a dedicated physical dial for PASM, as opposed to direct shutter speed and ISO control is simply crazy.
I hope the A6000 will have a hot shoe, or an accessory port like the one on the NEX-5 series, which can accept a wireless flash trigger.
micahmedia: For the full story open the resolution charts from Imaging Resource. The color star targets still look horrid.
This is still not ready for prime time.
Kudos to Adobe for taking up the challenge though! I'm curious if they can still take this further. Fuji would be foolish not to share some their secrets with them, but...well, I suspect they -are- foolish.
The new ACR demosaicing is based on the algorithm that Fujifilm gave to Adobe (and Apple). However, demosaicing is just the first step in RAW processing.
beckmarc: Great news on the Fuji x trans sensor support
It is supposed to use the improved demosaicing algorithm that Fuji gave to Adobe. That hopefully means less color bleeding and improved detail with foliage.
Apparently the Express version doesn't have local adjustments and dust removal features.
Marcin 3M: I wonder if the shake trajectory was extracted from the image, or rather recorded by accelerometers. They stated that it was calculated, but this calculation is time-consuming. I would like to know the theory behind.
My bad. Convolution is actually algorithmically more complex than FFT. So yeah it's almost certainly impossible to do anything better than O(N * log N).
It might not be necessary to FFT the whole image. They might be able to get away with FFTing just certain fragments of it. Once the kernel is known, of course the deconvolution must be run on the full resolution.
I haven't done deblurring, but have done deskew / auto-straightening of scanned images. First you find a usable area that you analyze. Or let's suppose you do Hough transform to find an angle of a black border. Instead of computing the sine waves at full resolution, you do a low resolution estimate first, then once you have the approximate angle, you compute it at higher resolution, but only around the estimated angle.
I'm just saying there might be ways to avoid having to FFT the entire image.
