6/14/2012 11:35:52 AM

Brightness/color

Brightness and colour is a bit of a vague term for these settings, including the Metering mode and Flash Compensation whereas similar options are in the Camera menu.

View mode

If you shoot both stills and videos then you’ll become familiar with this menu. They aren’t displayed together so you regularly have to switch folders to view.

ISO and White Balance performance

The main attraction is the 24.3MP sensor, so let’s see it in action.

ISO and White Balance performance

How much noise a camera produces is determined by several factors, the most important being the size of the sensor and how many photo-sites are squeezed onto it. The NEX-7 has a larger sensor than the majority of its rivals in the mirrorless market so you should expect less noise. The results back this up. The noise is still there but it’s well-controlled and not too distracting. The camera does a great job of dealing with high ISO settings, although you wouldn’t really want to use any pictures taken at ISO16000 at any great size or for anything important.

When it comes to the while balance, the camera tends to default to cooler colours and you’ll need to warm up the JPEG files. You can easily tweak the in-camera colours to match your personal preference, in fact, it’s probably a little too easy to do and could easily be done by accident while changing the white balance preset.

The new Micro Four Thirds model from Olympus has all the charm of the classic OM series but with an electronic viewfinder, 16MP Live-MOS sensor and a three-inch touch screen.

Fujifilm FinePix X-Pro1

Price: $2,145

Fujifilm’s latest offering has a special, Fuji-engineered 16MP sensor and oozes retro charm – it cloud easily be mistaken for an antique camera. Shame there isn’t a built-in flash though.

The resolution and high-quality video are the camera’s strong points, but it has enough to make it a winner in its class

Build quality:

With a solid metal body, the camera is undeniably well-built. The weakest spot is definitely the tilt LCD

Handling:

The NEX-7 is perhaps too complex for beginners but also not advanced enough for high-end users

Quality of results:

Excellent results overall from the NEX-7. You definitely want to shoot in RAW though a the JPRGs aren’t the best in class

Value for money:

The NEX-7 offers great value for money considering the resolution, but the handling lets it down

Score:

The NEX-7 is a clear winner in the pixel race but a few handling issues will cause problems for advanced photographers
