On BPG image format aims to replace JPEGs article (198 comments in total)
In reply to:

Peter K Burian: Here's a different perspective on this topic, IMHO:

For a new format to succeed, it would also need to be a capture option that cameras offer. ***Not just a format for use on Web sites.***

That would require all camera companies AND all software manufacturers get on this bandwagon. But they won't. The concept of a familiar JPEG format (especially for 90% of the population who are snap shooters, at best) is essential for the market. The fact that BPG is far superior is not relevant. It boils down to marketing and what the public will accept, as the camera manufacturers see it. Too many consumers would find a new image format to be an extra complication to deal with.

Serious shooters already have RAW capture as an alternative to JPEG. And snap shooters are happy with JPEG; they just don't know any better, and 90% do not even *want* to know.

Ok, here is another opinion ... http://www.gizmag.com/bpg-image-format-outperforms-jpeg/35232/

"""Is BPG likely to take over as a successor to JPEG? There’s a few factors running up against it. JPG is more or less doing a good enough job. Designers are comfortable with using it online, it’s well understood, it’s supported pretty much everywhere, and internet connections are becoming fast enough that image download times aren’t the issue they used to be...

Still, it's cool to watch clever people achieving clever things with software, even if the morass of patent law and commercial considerations do end up leaving BPG by the wayside."""

As I read more e-zines discussing this new format, I realize that it really is intended only for use on the Web. Not really as a capture format for digital cameras. And yes, it is preferable to JPEG2000 BUT ... until recently, ****JPEG2000 was the BEST alternative to JPEG.****
And yet, JPEG2000 was never supported by most browsers. So, why do we expect anyone to support BPG? http://www.gizmag.com/bpg-image-format-outperforms-jpeg/35232/

Starting with version 10 (released in September 2011), Adobe removed support of JPEG 2000 from its Photoshop Elements software. (The latest versions of Photoshop still support JPEG 2000.)

So, why was the JPEG2000 format not a huge success? Why can't cameras shoot in this format? Why don't many browsers support it?

Benefits: Better efficiency in compression (incl. 48 bit color depth support)
•Possibility of lossless compression>
•Decoding with different output resolutions>
•A process to calculate the integrated bit rate (possibility of reaching an aimed bit rate)
•Dividing the image into smaller parts to be coded independently from the others
•Improvement in noise resilience
•Access to the compressed bit rate at any point in order to access the image directly
•Better performances in coding/decoding through many different cycles
•More flexible file format

On Sony Alpha 77 II firmware update improves AF speed article (153 comments in total)

Yeah, no Review yet on DPReview, and some e-zines have already published updates to their original test reports .... indicating the actual improvement produced with the new firmware.

example: http://www.digitalversus.com/digital-camera/sony-alpha-77-ii-p20457/sony-alpha-77-ii-firmware-2-00-faster-af-xavc-s-video-n37597.html

"It's improved all round! In bright conditions, the autofocus is nearly twice as fast as before; and in low light, the Alpha 77 II has cut 40% off its previous time. The shot-to-shot time, whether in JPG or RAW format, has come down from 0.5 to 0.3 s. With these excellent results, the Alpha 77 II outperforms the Nikon D7100, Canon EOS 70D and even the recent Canon EOS 7D Mark II."

In reply to:

The Squire: Today, most people seem happy with terrible low resolution, artifacty JPGs - See any photo ever hosted on Facebook.

What will drive adoption of a new format?

Possibly web design. There's a trend now for full width images and even video on webpages. To keep these sizes small today, they tend to be very compressed. I can imagine HVEC-based compression, which seems to cut file sizes in half, being a popular choice if it is adopted by the major browsers.

Once those formats become standard on the web, we'll see greater adoption across image editing tools then... maybe... straight out of the camera. Maybe.

A well thought-out comment, Squire. But as my more recent post indicates, I'm convinced that for a format to become mass market, it first needs to be one that cameras can produce.

And I am convinced that JPEG will remain the norm for cameras and hence for software. In that case, BPG will be an orphan, used by a few major web sites, assuming that browsers even support it.

jhinkey: Well, I hope there are more advantages to this than just getting increased resolution. There are only a handful of native m43 lenses that can handle 40MP of true resolution. Hopefully there are some dynamic range advantages that come along with this.

The web site softpedia has some tech diagrams that explain this well too. http://news.softpedia.com/news/Olympus-E-M5II-Tipped-to-Arrive-with-Sensor-Shift-Will-Shoot-40MP-Pics-with-16MP-Sensor-466598.shtml

The site Softpedia has a much more thorough coverage -- with tech photos -- of this topic than any of the rumors.com sites. BUT is any of this actually accurate??? After all it is just a rumor. (Olympus might be working on this technology for a camera to be released a year from now.) http://news.softpedia.com/news/Olympus-E-M5II-Tipped-to-Arrive-with-Sensor-Shift-Will-Shoot-40MP-Pics-with-16MP-Sensor-466598.shtml

Another web site says this camera is ONLY official in Japan. Has it been announced for the US?

I wonder when we will see another headline?

"Acme Inc. to restart manufacturing of buggy whips" (Heaven knows, there are far too few buggy whip manufacturers.)

"Here we are faced with cameras that use the same sized sensor (although not all of it, in the case of the Lumix LX100), ............." That's a pretty casual mention of the fact that the LX100 does not use the entire area of the Four Thirds sensor.

In fact, the effective area of the sensor is only 1.5x larger than that of a 1-inch sensor. While some cameras, like the Fuji X100 series use a massive APS-C size sensor. (***Granted, the more important issue is pixel pitch: the size of the pixels, which would also be worth discussing. The Lumix LX100 would fare very well in this respect compared to many integral-lens cameras.***)

For what it's worth .. Four Thirds (as in the GX7) = area of 224.8mm squared.
LX100 effective sensor area = approximately 178mm squared
1-inch = area of 116mm squared
Canon G1X = area of 261.8mm squared
APS-C = area of 368mm squared

In reply to:

Rooru S: If they want professionals to take Sony seriously, they shouldn't stop R&D of A-mount lenses. There is a bunch of lenses that need an update quickly and there are serious holes in the A-mount lineup (for example, a set of constant F4 zoom lenses to complement the SAL1635Z, SAL2470Z, SAL70200G).

And if we talk about Camera bodies...where is the 1DX/D4s competitor that many professionals prefer to use? What about a proper D800 competitor with a proper AF module? Right now the a99 is only competing against the D600/6D and is losing.

Right now the Minolta Engineers are thinking what the hell they're doing with Sony after they're leaving A-mount in the dust...

Sony already has fabulous Carl Zeiss lenses. Not enough in the mirrorless category of course, but they are working to develop more. The big question is, In the mirrorless camera owner market, how many will pay big bucks for pro-grade Carl Zeiss lenses?

In reply to:

lbpix: I think a mirrorless full frame would be great. I've really enjoyed using the Fuji XE but love the quality and dynamic range of full frame. Go for it Nikon.

The larger the sensor the larger the camera and lenses must be. A primary goal of mirrorless was to reduce camera and lens size.

Granted, the omission of the reflex mirror and pentaprism would make a full-frame mirrorless camera smaller than a full-frame DSLR. But small enough to attract any potential buyers?

Raw Jaw: How can the section "Serious mirrorless" not include Samsung's NX1?

Samsung's problem is that they are not successful in getting the photo retail channel (camera stores) to stock their products. HUGE ones like B&H do, but the more typical stores often do not.

In reply to:

quokka: I am surprised that there appears so little interest in Canon's 400mm II DO lens, and that few have linked the advent of this lens to the 7d II. The combination of these tools should be a BIF shooter's dream, with NO real competition. Furthermore, based on MTF charts, this lens should take the 1.4x and 2x adapter quite well, delivering lightweight, yet very functional 560mm and 800mm capability. Good time for birder's.

...of course, this is all on paper. We shall see.

Who gets excited about a $300,000 Rolls-Royce? The DO lens is $6500 and huge.

Dimensions 5.0 x 9.1" (12.70 x 23.11 cm)
Weight 4.27 lb (1.94 kg)

Granted it's $3000 less than the 500mm f/4 which is $9500. Fortunately there are many such lenses for sale in the used market. Rich guys buy them, use them once, and sell them for a lot less money.

In reply to:

Gesture: Look at the modern DSLR. It has outgrown its ergonomics. Even the entry level models are ridiculously complex. One of the appeals of mirrorless is the streamlining of the body and interface.

Well the bodies are smaller (though some are not very small) but the interface is also not streamlined with some models; they are really like smaller DSLRs. Similar specs and similar controls.

AND removing external controls makes a camera very heavily menu dependent. Is that better than setting a function with a dial or knob?

In a week at photokina you only got a single photo of the buildings? (at the start of this article). And that was taken before the show started.

I'm sure there were hundreds of people outside the building, not three or four. A photo like that would provide a feel for the event.

On Panasonic Lumix DMC-LX100 First Impressions Review preview (1869 comments in total)

Nice to see that you discuss the fact that only a portion of the Four Thirds sensor is actually used. (Many Web sites ignored that.) But, the effective area is 1.6x (not 1.5x) larger than the 1-inch sensor.

Quote from Panasonic: DMC-LX100 has a large 4/3-inch High Sensitivity MOS Sensor ... approx.1.6x larger than the 1-inch sensor. ...
