DxOmark tests the Sony FE 24-240mm zoom:
DxOmark (Click here) posted the full Sony FE 24-240mm lens test. They write:
Costing $998, the FE 24-240mm is not very cheap, but packing a massive 10x focal range, Sony’s OSS image stabilization and dust/moisture resistant construction, you get a lot of lens for your money.
While offering a versatile all-in-one solution for wide-angle or long telephoto shots without having to change lenses, the FE 24-240mm is not the strongest optically and ranks in the lower half of our lens database. That said, the image quality delivered by the FE 24-240mm is good for a superzoom, and as we’ve seen in the Sony FE 24-240mm vs Nikon 28-300mm analysis, the Sony is as good in most areas and actually slightly better than the Nikon at the wider apertures.
The FE 24-240mm’s performance is also better at the wider focal lengths between 24-50mm. Zoom in further to the telephoto focal lengths and Sharpness and Transmission start to suffer somewhat, which has affected its overall score. Head-to-head against the $1,498 FE 70-200mm f4 G OSS, the analysis showed that much better performance is available from a dedicated telephoto zoom with more homogenous sharpness across the entire frame. At the wider focal lengths, however, the FE 24-240mm actually displays better edge sharpness than the FE 28-70mm standard zoom, which covers a much shorter focal range. So if you’re looking for a good quality standard zoom with the added versatility of being able to shoot telephoto without changing lenses, the FE 24-240mm is a convenient and good value choice for Sony A7 shooters.

Gariz launches the gorgeous Alcantara case for the A7 cameras.
Gariz launched an extremely gorgeous Alcantara version of their A7II case. You can already buy it here:
On eBay in Black (Click here) and Red (Click here).
On Amazon US in Black (Click here) and Red (Click here).
Alcantara is not leather and has the following advantages:
– It feels like leather but it is not.
– Increased durability and stain resistance over leather
– It doesn’t make you sweat.
– It’s flame retardant in case your camera gets launched in an open fire
P:S.: Alcantara is composed of about 68% polyester and 32% polyurethane and is very much used in Sports cars because it feels good but you don’t sweat in it.

(SR3) Sony A7rII with 36MP sensor, IBIS and faster AF
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.

Sony has a new 12 MP RGBW Sensor for the next iPhone.
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.
