It is naive to think that big corporations make big money by being totally honest ... I don't think these documents should be released, its a dangerous game and I don't think CR has the money or the power to fight a big corporation like Canon ... but be my guest and prove me wrong.

If you're not shooting in RAW, why are you even taking the picture?
;D ;D ... that's a good one ... unfortunately, I've actually heard a guy say that.

Heh, it was probably me :)
;D ;D ;D

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?

Landscape / Re: Deep Sky Astrophotography

Hi Jon,
If I go with a budget of $1000 (along with my current gear below), what telescope and/or accessories would I need to start off Astrophotography?

Ok, Sigma made the "Best" Superzoom of em all... but 9 MPixel Resolution @DXO? This lense isn't even able to serve a old Canon 60D or even a 50D? People who buy this kind of gear should head to the Sony RX1, they get a far better and smaller System @f2.8

No offence.

Bro, it's all relative.  That sharpness beats out its competitors.  Were you expecting a score of 16 MPixels or something, which is the score the Canon 24-70 2.8L II got?  That lens is $2300, this one is $400.  You gotta be able to keep your expectations in check when you're buying a bargain lens.  This ain't no L or Art glass homeboy.  Additionally, most people who are buying such cheap lenses that cover such a wide range aren't going to be those who are super critical of maximal sharpness.  If you are, then any smart person knows you need to step up to where the big boys play and get out that big boy checkbook to buy that razor sharp prime.
I agree with the point you are making, but I would refrain from using the lines struck off above ... coz that kind of language comes across in a condescending way.

Congrats to Sigma, although I personally wish they could have stretched it to 250mm (for a 400mm equivalent). As most of you already know, many times it's not the equipment, but what you do with it. Case in point if I may ... the following representative shots were taken with Sigma's "old" 18-250 Macro OS and a humble T4i on a trip through Myanmar (Burma).
Those are beautiful images ... and I agree that a good craftsman can make compelling images with the available tools. Well done!

I think this is a very good idea for any camera that does not have a tilt/flip LCD screen and Surapon as usual is the master of coming up with such gadgetry ... here is a link to his thread on how he did it:

On the same subject, one of the CR members (pdirestajr) shared this Flipbac Angle Viewfinder ... its a neat little tool for those who don't have a flip screen and would like to have one for under $15.
Original post by pdirestajr can be found here:

It's a nice workaround if you need a flip screen, but those reflections are very obviously fake :D

Agreed.  If I recall correctly... the angle of inflection is equal to the angle of deflection.

You guys are wrong ... this fliback angle viewfinder can defy the lawas of physics for just $15 ;D

EDIT: Before someone thinks its true  ::) or starts blasting me for leading people astray, let me clarify that this flipback angle viewfinder reflects a flipped view of the image of the EOS-M's LCD screen.

Several rear-ends in one go  ;D
Several rear-ends, such as these, in one go are far far better than just one rear end ;D

Just got an a 6000 for my parents
And I'm sorry to say the AF is not much different to that of the EOS M
Anyone else notice it's not living up to the hype?
Looks like you may have gotten a defective camera, coz everyone I know who got the a6000 and every review on the internet say that the AF is absolutely fast and accurate.

Interesting ... don't forget that Tamron is coming up with 16-300mm lens for APS-C DSLRs ... but still, $399 is a bargain for this Sigma 18-200 OS and is worth the money and provides a good compromise for travel photography, when you can only carry just one lens but also want some good wide angle views and telephoto reach.

I hate to say it but DigitalRev guy reminds me of a few guys on here, except…again…Revguy is funny and less hateful!

As much as Kai is a little abrasive at times I have learned from their videos, and the three of them (he, Lok and Alamby) add up to better chemistry than a lot of contemporary TV.  I wonder how they are off-camera, I'm pretty sure Kai is hamming it up a lot.

I agree. Some people don't like them but I find their videos entertaining ... they are not pretending to teach you or make you into a professional photographer ... its meant to be informative and funny, which works well for them ... that's the reason why they are the number 1 photography video channel on youtube and many professional photographers participate in Kai's videos, especially for the "cheap camera challenge" videos. From what I hear Alamby left the show and all the new videos for the past few months only show Kai & Lok.

Times square, 2013
6D 135mm f2
;D ;D ;D ... I thought this image was captured in the 80s, until I saw you mention that it was made in 2013 ... can't believe a guy walking around in underwear and a big a55 boom box in times square.
