Developers will be able to build applications to remotely control two Sony lens cameras, using new features the company has added to an SDK.

The QX10 and QX100 lens cameras don't have bodies. The camera is instead integrated into what looks like a normal lens, with a smartphone serving as the viewfinder. The two communicate wirelessly with each other, which means users don't need to hold the camera to use it.

Using the Camera Remote API beta SDK (software development kit) any developer can build apps to control a number of different settings on the two products. A new version made available Wednesday includes access to touch autofocus, exposure mode and white balance on the QX10 and the QX100. Developers can also access shutter speed and F number settings on the QX100, according to Sony.

Features already supported include image capture, video recording, zoom and timer.

The SDK is also compatible with a number of other Sony cameras, but functionality is much more limited. The SDK can be downloaded from Sony's developer website.

To help developers get started, the SDK also includes a new iOS sample code project that shows how to implement device discovery, record videos and take pictures. The sample code for Android has been updated with an improved user interface and Sony has also improved the connection stability.

The QX10 and QX100 were launched in September at the IFA trade show in Berlin. The QX10 has an 18-megapixel sensor and costs £179. The QX100 has a 20-megapixel sensor and costs approximately £399.
