By end of 2015 Pentax will announce their first digital Full Frame DSLR (picture can be seen on top). Rumor has it that Pentax will use the current Sony 36MP sensor used by the Nikon DSLR and Sony A7r. The very important news is that it will feature a High Resolution shooting mode according to the reliable source Thistanaka. The same feature is already used by their brand new K-3II:

The K-3 II is the first camera in the PENTAX line to incorporate Pixel Shift Resolution® for capturing still life subjects with ultra-high resolving power. Pixel shift technology uses the camera’s in-body Shake Reduction mechanism to move the image sensor at single pixel increments, capture 4 separate images, which are subsequently combined into a single high definition image. Benefits include higher resolving power, reduced false color and improved overall image quality of non-moving subjects. 

If Pentax can use Sony sensor and their on sensor stabilization for high-resolution mode…than Sony should do this too! As Diglloyd reported such a feature on the A7rII could generate 144MP raw files of your…cat pictures :)

After one of my trusted sources told me that Sony was already producing the A7rII things got a bit silent here. I believe Sony will make a “silent” announcement of the camera just like it happened with the A7II. This means no bloggers and almost no photographers will be able to get their hands on the camera in advance. And if you remember the A7II got announced in Japan only at first.

According to a person who was able to get in contact with a person from Sony Japan this is what to expect with the A7rII:

 It has same 36Mp sensor and from what I’ve been told it will have EFCS and IBIS and faster AF.

The A7000 (or whatever the final name will be) is coming in mid-June. So let’s hope the A7rII is coming too and will not get any delay like it happened with the A7000. Remember while the A7000 release info should finally be the right one I am yet not(!) sure when the A7rII is coming.

While this news is not directly related to the Alpha World it’s still interesting to hear about Sony’s future sensor tech. Feng.com reports that the next generation of Apple iPhones will use a brand new 12 Megapixel RGBW Sony sensor. The “W” stands for “White” pixels and it allows to increase the sensitivity which is a weak point of current smartphone photocameras. Usually those RGBW sensors have as a consequence that the pixels size decreased and therefore the image quality gets poorer. But Sony claims they solved this with a new kind of technology (not explained yet):

While the individual pixels of the Sony models are extremely minute at 1.12μm, the incorporation of the “RBGW Coding” function has realized a SN ratio (signal-to-noise ratio) equivalent to that of a unit pixel size of 1.4μm under conventional methods, which in turn has enables the image sensors to achieve a higher resolution at a more compact size.

Don’t know if that RGBW sensor tech will be applied on future APS-C or FF sensors too.
