Photographers will have to wait even longer for Sigma’s SD15 DSLR, which has been on the cards since the beginning of last year.

The SD15 – due to house the same 14-million-pixel Foveon X3 imaging sensor employed in Sigma’s current SD14 model (pictured) – was first announced at PMA in 2008.

But its launch was put back until this summer following a modification to the imaging processor.

Asked whether the SD15 has been put on hold permanently a Japanese spokesman said: ‘The SD15 digital SLR is in development and making good progress.

‘The Japanese engineers are currently in the process of optimising performance and image quality, ensuring the best possible results are achieved from the Foveon sensor.

‘Whilst an on-sale date for the camera has never been formally published, we will announce the availability in due course.’
