Speaking at Photokina, Shigeki Ishizuka, president of Sony’s Digital Imaging Business Group, announced four lenses that are under development.

These are the Distagon T* FE 35mm f/1.4 ZA; FE 90mm f/2.8 Macro G OSS; FE 24-240mm f/3.5-6.3 OSS; and FE 28mm f/2.

They are expected to arrive from March 2015, apart from the 24-240mm, which should arrive in February.

Sony, which currently has five FE lenses, announced the launch of two more at this week’s Photokina: a Zeiss Vario Tessar FE T* 16-35mm F/4 ZA OSS; and FE PZ 28-135mm f/4 G OSS.

The 16-35mm is due to be shipped from next month, with the 28-135mm arriving from December.

Prices have yet to be announced.

In an interview with AP at Photokina, Sony outlined plans to shake off what it claims is a general perception that compact system cameras are ‘inferior’ to DSLRs.

The firm has pledged to continue developing new technology and lenses in a bid to tempt photographers away from their established Canon and Nikon systems.
