A new firmware update further boosts operability of the α77 and α65 Translucent Mirror cameras from Sony.

Available for free download from 29 March 2012, firmware Version 1.05 adds several enhancements to both cameras. Alongside heightened responsiveness, it improves operability of both cameras with a wider choice of A-mount optics by Carl Zeiss and Sony.

Shading and aberration compensation

Both cameras can now intelligently correct vignetting, lateral chromatic aberration and distortion for a total of 11 A-mount lenses, including a further six models that are now supported:

• SAL-24F20Z (Carl Zeiss)
• SAL-85F14Z (Carl Zeiss)
• SAL-135F18Z (Carl Zeiss)
• SAL-70300G (G Lens)
• SAL-35F18
• SAL-50F18

Improved responses

Operability of both cameras is further improved with a number of refinements that facilitate smoother, faster handling.

• Auto review responses are now quicker, without a 'processing' message being displayed
• Time between power switch operation and power off has been shortened
• Front/rear dial responses are improved

Autofocus responses and precision

Autofocus accuracy is now improved when focusing on scenes with wide contrast difference between objects (applies to SLT-A77 only). In addition, AF speed is improved when using both cameras with the recently-announced SAL500F40G 500mm F4 G SSM super-telephoto lens by Sony.
