On article Apple revamps MacBook Pro lineup, adds 'Touch Bar' (871 comments in total)
In reply to:

sirok: Apple has lost their way since Jobs left. The Microsoft surface is beating Apple at their own game ,might not like the Os but the Hardware is great. Lots of college students use surface, you can take notes on the screen , flip it around as a Laptop etc. Lots of IO ports. What can you do with a Ipad Pro with no graceful way to get stuff off of the the freaking thing (no USB etc.) and no file system . And what about us Power users , No MacPro Desktop for years. Mac Minis and Laptops do cut it. I'm a long time Mac use and really think Apple wants to get out of the Computer biz.
Hackintosh here I come. Sierra, Really ?

The Surface is nice but can't compete against the 15" quad-core MBP in terms of performance. Which is an issue for working photographers.

iamatrix: This is a really good looking laptop, I was astonished by all the negative reviews, I think it just shows how poorly educated consumers are about technology. The new processors, faster SSD throughput,faster ram chips, improved screens, fast modern USB-C standard (and 4 ports!) adds up to extremely impressive machine especially for media professionals. I benchmark machines for a living it is truly impressive what Apple can squeeze out of their hardware due to their incredibly close relationship with hardware manufacturers, in all my years benchmarking machines for a major publication I have never seen such impressive throughput. In fact I'll take quite the opposite stance from other folks here and say that after 20 years as a very avid Windows user this will be my first Mac ! Kudos Apple. And discouraged Apple folks I will tell you it's not what's on the Surface that counts, but what lies underneath -no pun intended ;)

The cooling is a major point. The new 2016 MBP claims to have a redesigned cooling mechanism with heat pipes though. Let's wait and see if Apple could solve that problem. Would be my #1 reason to upgrade.

Tommi K1: Isn't it meant to be written as 21'650 frames per second?
As 21,650 frames per second reads like 21 and 650 fractions of frames per second...

It is 21,650 in the EN locales, 21.650 in DE and 21'650 in CH locale. I guess Tommy is from Switzerland ;)

jhinkey: Hopefully it will be much sharper than the Sony RX10-II at the high frame rates - I found the image quality (specifically sharpness) to be highly disappointing at 1,000 fps.

It performs exactly as advertized. If disappointed, then you expected a miracle.

On article Ballot-selfies are now legal in New Hampshire (50 comments in total)

Rather than punishing selfies, it would be much better to educate people to stay silent, or lie, on the question on who they voted for.

After all, the vote is free only if free from pressure from the social community you are living in. Worst would be a culture where you are expected to post your vote on FB.

This is good news.
First, the margins are pretty standard, after all, the smartphone is more software than hardware and software is what created the smartphone and killed Nokia and Microsoft in that market.
Then, 20$ per camera module mean that 3x3 camera arrays have become an economically viable option. Still 180$ per array, but feasible for, say a Plus model. The competition for smartphone camera modules also is what made multi module cameras like the 36-camera Panono a reality.

Eventually, let's note that more money doesn't really buy better camera modules as the slim form factor dictates lens aperture and possible sensor size.

I read a lot of criticism about this lens and its price point.
However, if rumors about it being really sharp are true, it may be the only TS lens which really does make sense. Because a pano head and software stitching yields very high rez architectural results, using lower rez TS lenses might fall short in competitivity.

Dr_Jon: So they are scaling 5,472 to 4k (well 3840 across, 4096 isn't present, which is fine for pretty much everybody I assume), how does that work for aliasing and moire, as their previous efforts at small amounts of down-scaling haven't been great?

http://www.sony.com/electronics/cyber-shot-compact-cameras/dsc-rx100m5/specifications

@Dr_Jon, you may be confusing things here.
Downsampling (if supersampling) helps with moiré, rather than what you seem to assume. The A7s you linked to doesn't do downsampling 4k. But it is already better with its full sensor readout than line skipping cameras like many DSLRs.

EDIT Your a6300 link is misleading too. The aliasing 4k sample chart does look pretty good, just not perfect. And the a6300 may not do any supersampling at all, so your comment may not even be applicable. Did you check any facts before posting?

Mutovkin: Stabilization is a major weak point of the camera it seems. Would love to see it compared against 1" cameras from Canon, Panasonic side by side (i.e. on the same mount) while walking.

I don't think this can be concluded from the video. The camera was shaken too much to give stabilization a chance. The opening sequence looks pretty stable though (handheld too).

In reply to:

Max Iso: Here's the weakness i see, the AF tracking (at least in video). When the last shot used face tracking and when you guys used single point on Sam's face, it was the same both times. It starts in focus, then the camera is moved towards or away and the camera doesn't get the face back in focus till the movement stops.

You could almost get the same results just using S-AF at the beginning and then after movement stops at the end. There wasn't anything "continuous" about it. I know it's harder to do in video but we have seen how many generations of OSPDAF? Canon is on their 2nd gen of DPAF and they do much better at actual continuous tracking for video.

Maybe not a deal breaker for people who want this cam but C-AF in video just isn't there yet in anybody but Canon. Reason i bring this up is i assume DPR are implying it's good and i just didn't see that.

@Max Iso
Thank You for your observation and comment.
It is a valid comment as it compares technologies in wide-spread use. PDAF sensors are in phones now, as is Dual Pixel AF (Galaxy S7). DPAF was first shown by Canon, but the corresponding patent is a joke and won't stop Sony if they only liked. Yes, Sony has to amp up their AF game if they want to stay competitive in the AF area.

scastle: Interesting. If you go to their website and plow through the menus, you'll see they also have a Canon 700D that has been modified this way. And there's something a bit curious: the sensitivity graphs they have for the two cameras are exactly the same. It makes me wonder if the graphs were just made up.
http://www.primalucelab.com/astronomy/ccd-cameras/700da-cooled-camera.html

The "sensitivity graph" is a filter transmission graph. Assuming they use the same IR replacement filter material, both graphs should indeed be the same. The transmission curve of the original filter is very similiar too, but not identical.

vscd: I'm still interested in an article about warming up sensors and the impact on the sensornoise. Back in the good old days shooting in live view was always said to be less recommended because the sensor heats up. Nowadays the mirrorlessbunch runs the sensor for hours until the photo was taken and no one seems to care. Are the problems solved or just kept quiet?

I recommend Brendan Davey's gorgeous resource:
http://www.brendandaveyphotography.com/?page_id=726

It should be read as an extra metrics complementing the DxOmark rating of any sensor.

Not in Italy. They make very good ice!

gehairing: Maybe i've missed something ?
It's the same price as an entry level dedicated astro CCD wich is much easier to use. Better sensitivity, no mirror, smaller, T2 treading etc...

A dedicated astro CCD in the $2000+ range uses a sensor like the Truesense KAF 8300 CCD. It is slightly smaller and has 8MP. More importantly, as known from medium format cameras, such sensors have much worse dynamic range properties than state of the art CMOS with column-parallel ADCs (the KAH 8300 has a readout noise of 16 e-). Therefore, IMHO it makes a lot of sense to adapt a state-of-the-art system camera and the D5500 is relatively low price.

In reply to:

Polacofede: Doesn't a Pentax K3II offer better astrophotography capabilities with the astrotracer? It might allow for 900seconds but without a way to trace is useless.
Also I wonder how much can the sensor heat to have an impact on the IQ coz if then I might add some ice under my K3II. LOL

This is for serious astro photographers with motorized tracking mounts. Which is why the D5500A also has a modified IR filter and an anti-dewing feature.

The Pentax astro tracer is nice for what it is, esp. for long exposure at wider field of view. But it lacks the required accuracy of an astro mount for serious astrophotography at long focal lengths.

Sensors create a noise called dark current which drastically increases with temperature and is linear to exposure time (hence the term current). Cameras perform differently here, cf. the stunning resource http://www.brendandaveyphotography.com/?page_id=726 by Brandan Davy. The D5500 is missing from the list, but Pentax K-5 and Nikon D7000 are good APSC performers. I suspect the D5500 was selected for being among the best too.

Link | Posted on Oct 14, 2016 at 13:25 UTC

The DPR price quoted in USD is wrong!

The D5500A is 1795.08 € (w/o TAX) or US$ 1976.16. Any US buyer wouldn't need to pay EU VAT taxes.

goldenstandard: This is really interesting. From what I can tel, this isn't a patented technology, so hopefully this will become standard smartphone tech moving forward...
Also, the gray-scale g that's close to the center of the graphic is just a mistake, right?

The pattern is from a related article and seems accurate as is. The actual pattern of the IMX378 was not disclosed by Sony.

The pattern repeats every 4x4 sensels. Each 4x4 block consists of 2x2 Bayer RGGB blocks with varying average sensitivity. The average Bayer block sensitivity is 87%, 67%, 37%, 67%. One could call it RGGB-WGBG pattern. The detail Bayer blocks are such that each color receives light at 25%, 50%, 75%, 100% sensitivity once (RB) or twice (G). Therefore, I think the pattern is depicted correctly.

kanega: The SW320 was already on display at the recent Photokina.
Impressive display!
They demonstrated the HDR mode with a clip of 'Life of Pi', gorgeous blacks and highlights, depth.
Price they told me was 1399€.
Will def. get one!

I very much appreciate your info. thanks!

Henry Alekna Photography: Looks nice enough but I think I will still be better off assembling my own using a laptop hard drive.

Incidentally, why do they bother making a Mac version? I use a couple of Toshiba external drives which are supposedly for windows, formatted in disk utility and they now work great!.

Well, the Mac version is the black Windows version, same price. Only difference is that it is preformatted HFS+ rather than NTFS. The tools are both Windows and Mac anyway.

Why WD does it? I guess to be displayed in Apple Stores. Preformatted with HFS results in an easy user experience: Plug the drive and the time machine prompt will ask wether to use it as back-up drive. A simple ok is all what is needed to configure. Apple wouldn't stock NTFS-formatted drives, I guess ...

Originally, the difference was in hardware too, with the Mac version sporting a Firewire port.
