Sony is one of the big sponsor at the Football World Cup in Brazil. Even though photographers are “forced” to wear Sony 4K advertising vests, as you can see from the 360 degree pics posted at, not a single one of them shoot with a Sony. It’s all about Canon (and few Nikon). Let’s hope Sony will make a real Alpha Full Frame Sports camera that will convince some of them to switch over to Sony!

Third Party Manufacturers / Premium Digital Camera Market Increasing

Interesting info at:

Photokina agency debunks some myths: Premium Digital Camera Msrket is increasing.

The last couple of years we heard a lot about the digital camera market being in crisis and the new mirrorless system cameras not taking off. Well, the Photokina partner agency GFK shared some unexpected data (Source: MirrorlessRumors):

1) Revenue increasing:
 While it’s true that in terms of numbers the companies are selling less cameras it’s also true that companies are selling more high profit margin premium cameras! This means the last couple of years average price of the cameras increased (and therefore also the profit margins increased).

2) Mirrorless is taking off (slowly).
 While Mirrorless keeps being not popular in US it’s taking off in all the rest of the world.

3) Premium fixed lens camera is growing fast
 Sony certainly did the right thing with the RX line. They offered a premium and class leading range of fixed lens camera that are to-day unmatched by other companies.

The current trend in the market goes in favour of Sony that leads the probably two fastest growing segments in the digital camera market: Mirrorless and premium compacts. And as an addendum watch this nice graph that explains why smartphone users actually buy a larger sensor camera:

Third Party Manufacturers / New Curved Sensor Tech by Sony
« on: April 04, 2014, 02:25:59 AM »
Sonyalpharumors reports the following interesting info:

If you follow SAR closely you will remember I posted two great Sony patents: One about a Curved Sony sensor tech and one about a 35mm f/1.8 Full Frame lens designed for curved sensor. Now, usually it takes years before a patented idea will be materialized in a real product. But you know, Sony cannot afford to avoid to sit down and stay still. They have to make real inovative products in order to catch up with the big two Canon and Nikon.

And the good news is that this is no more a dream! Image sensor World reports a great news. Sony will officially present their curved sensor technology at the Technology Symposium! This is what Sony writes about the presentation they are going to make:

We realized an ultimately advanced imaging system that comprises a curved, back-illuminated CMOS image sensor (BIS) and integrated lens which doubles the sensitivity at the edge of the image circle and increases the sensitivity at the center of the image circle by a factor of 1.4 with one-fifth lower dark current than that of a planar BIS. Because the lens field curvature aberration was overcome in principle by the curved sensor itself, the curved BIS enables higher system sensitivity through design of a brighter lens with a smaller F number than is possible with a planar BIS. At the same time, we controlled the tensile stress of the BIS chip to produce a curved shape that widens the energy band-gap to obtain a lower dark current. The curved CIS can be applied to an ultimately advanced imaging system that is validated by the evolution of the animal eye in Nature.

Now combine that sensor tech with a small and fast 35mm f/1.8 lens and you will get a superb new RX2 camera! More compact, faster and of much higher image quality than the current RX1-RX1R. And we also can hope to see an interchangeable mount camera with such a sensor in near future too!

I cannot wait to get some rumors about the RX2. If it has that kind of curved sensor tech I am sure SAR readers will be exctided about this. Or not?

Third Party Manufacturers / Sony Medium Format Camera
« on: March 25, 2014, 09:41:45 AM »
According to Sonyalpharumors, Sony may announce a Medium Format camera ... that' interesting ... they are also running a vote if one would buy a Sony Medium Format Camera if it came with a fixed lens (like Sony RX1) for $5000 ... I voted No, but would you buy a $5000 RX camera with fixed lens and Sony's new medium format sensor?

Thought of starting this thread to talk about inexpensive non-electronic replacement accessories (as opposed to the expensive OEM accessories e.g. tripod collars, lens hoods, lens caps etc etc etc) that make our camera gear a bit more productive or just look cool. I thought of this as I just received 2 new White lens hoods for my EF 70-200 f/2.8 L IS II & EF 10--400 L IS lenses ... here are a few pics ... I already have the original black lens hoods that came with the lenses, but I kinda prefer the white hoods, that are found on the higher end Canon L lenses ... this is my "poor man's attempt" of trying to make my 70-200 & 100-400 lenses look like "limited/special edition" ones  ;D
I paid US$ 29 for both of them ... while the original Canon versions cost around US$ 93 ... me thinks the cheaper white ones look cooler.

EDIT: I removed the non-electronic part as several members have already posted some good electronic alternatives, so I thought why limit this thread only to non-electronic accessories ... post whatever caught your fancy.

Sonalpharumors reports the following rumor with a SR5 rating (i.e. "almost certainly correct!")

(SR5) New Full Frame E-mount cameras to be launched within the next 5-6 months (likely at Photokina).
I can confirm via multiple trusted sources that Sony will launch new Full Frame E-mount cameras within the next 5-6 months. I guess it means they will be launched right before the Photokina September show. NONE(!) of them will be a replacement of the current A7 and A7r models. All we know for sure about these new models is that they will have an advanced hybrid AF system similar to what we got inside the newly announced Sony A6000.

The surprises: I can already tell you that there will be many more cameras in the months to come (RX and Alpha and E-mount). I am working on those rumors right now….be patient ;)

That is a very interesting development, coz the a6000 auto focus system has received a lot of praise from pretty much every photographer who got their hands on it ... and from what I've seen on youtube videos, it does seem to be awesome ... and to have it on a full frame camera (which might be priced modestly) is even more awesome ... exciting times.

Over at Nikonrumors they posted this:

The Tokyo district court ordered Sigma to pay 1.5 billion JPY (around 14.5 million dollars) compensation to Nikon as a result of the patent infringement case for lenses with VR technology that was filed back in 2011. The lawsuit was based on six Sigma lenses with image stabilization technology. Initially Nikon was looking for a compensations of 12 billion yen (around 116 million dollars).

Here is the summary of the judgment:

"Nikon obtained the patent related to VR technology in 2002. The content of the patented invention relates to technology wherein a vibration detection device, which detects the amount of camera vibration at angles around photographic objects, prevents the influence of vibration of a motor for lens and thereby allows more accurate photo shots. Sigma affirms that the scope of the patented invention does not include any functions which reduce the influence of camera shake. However, Mr. Osuga, the Judge in Chief, states that the effects of the invention in Nikon’s specification is described as “it allows image blur to be reduced” and that the specification clears that it includes camera shake. Thus, Mr. Osuga stands for Nikon’s assertion. In addition, Mr. Osuga points out that image blur prevention system requires various control functions, and he states that this patented invention of Nikon’s should be rewarded based on the contribution of the patent to the defendant’s products, that is 15%. Therefore, the Tokyo District Court calculated profits earned by Sigma to be a maximum of 10.1 billion JPY, and found compensation of damages to be 15% of the profits of the accused products earned by Sigma."
