Phase One’s IQ250 is a medium format back meant for the very high end shooter. At 50MP and not being a full frame 645 chip (it is cropped) you get the change over from CCD to CMOS with the smaller overall size as a tradeoff. Additionally, the back packs in Wifi transmission, a touch screen, great build quality, and some of the best RAW files that we’ve tested.

But interestingly enough, the Phase One IQ250′s biggest flaws have nothing to do with any of these or even the product itself.

DxOMark has analyzed the sensor of the new Nikon D4s, and the results aren’t really surprising. Since the camera is more of an update to the D4 rather than a full-fledged successor, we didn’t really expect the D4s to outperform the D4 by any significant margin. And indeed, this is what DxOMark’s measurements confirm. While the D4s has slightly better overall performance at ISOs 3200 and up, the D4 performs just as well if not a slight notch better at lower ISOs when it comes to dynamic range, tonal range and color sensitivity. The same is true for the Nikon Df.

Phase One IQ250

Photographer Tim Kemple is no stranger to the Phoblographer. We’ve interviewed him before about his work in the great outdoors and his photography in general. But when we heard that he got to play with the new back, we were extremely curious to talk to him about it.

Not only was he able to tell us a bit more about the experience, but he was kind enough to provide crop examples of the new back against the Nikon D800.

The NEX 5 line has been refreshed again, this time to a T. Identical in size and shape to its predecessor the 5R, the 5T comes with NFC for transferring images to your phone. With 16.1MP on an APS-C sensor, the 5T has the same spec sheet as the 5R which means that it will produce the same high quality images. This is my first extended stay with one of the more mid-range NEX cameras, and it’s been swell.

Chris Gampat The Phoblographer Olympus OMD EM1 Product Photos (8 of 8)ISO 2001-40 sec at f - 2.8

The Olympus OMD EM1 is the company’s new flagship of flagship cameras–it replaces their aging E5, which was a DSLR. Interestingly enough though, this camera is a mirrorless Micro Four Thirds camera. Rumors of the camera were abound for a while and we’ve been working with a review unit for around three weeks. Complete with a 16.3MP LiveMOS sensor, TruePic VII imaging processor, WiFi, weather sealing, a brand new viewfinder, and lots of new controls, the camera is an aggressive stab at the flagship mirrorless camera world and the high end APS-C DSLR lines offered at the current moment.

But does the company’s new flagship have enough in it to deliver and cater to the needs of the professionals that it is targeted at?

Samsung ISOCELL Smartphone Camera Sensor

In an attempt to further optimize the image quality of small smartphone sensors, Samsung has developed a new technology called ‘ISOCELL’, which promises better color accuracy, less noise and greater dynamic range as compared to current BSI (back-side-illuminated) CMOS sensors. Basically, what Samsung did was to put physical barriers inbetween individual pixels (hence the name: ISOlated CELLs), which greatly reduce light spill as well as crosstalk between pixels. Samsung calculates that this new technology will decrease crosstalk between individual pixels by as much as 30%, meaning more light will be captured by each individual pixel.

A first sensor using this new technology has been created, sporting 8 megapixels on a 1/4″-type device. Mass production of the new sensor is scheduled for Q4 2013, so we might actually see it featured in smartphones or tablets some time next year.
