A new firmware upgrade adds further operating refinements to the NEX-5/NEX-3 compact system cameras from Sony

Available now for download with versions available for Windows and Mac OS2, the free upgrade adds several performance enhancements. Autofocus is now supported when using the NEX-5/NEX-3 with 14 lenses from the full range of A-mount optics by Sony and Carl Zeiss that includes telephotos, primes and zooms. Aperture settings can be maintained during HD movie recording, and system menu operation has been streamlined alongside other usability improvements. Registered NEX-5/NEX-3 owners will be advised of the free update via email.

Autofocus with A-mount lensesSingle-shot autofocus is supported with 14 optional A-mount SAM and SSM lens models3 when used with the optional LA-EA1 Mount Adaptor. Single-shot AF is also possible while in movie recording mode by pressing the shutter button halfway down. Support for AF operation with A-mount lenses also requires a separate firmware upgrade for the LA-EA1.

Aperture priority with video recordingHD video can be shot while maintaining constant aperture, either in A (aperture priority) mode or in iAuto mode with background defocus activated. This aids the simple creation of beautiful background defocus effects during movie recording.

Soft key settingsIt’s possible to customise functions of two of the three soft keys on the camera’s rear panel. Functions that can be assigned include Shooting Mode, Shooting Tips, Precision Digital Zoom, ISO, White Balance, Metering Mode, Flash Compensation, DRO, Auto HDR, Creative Style, MF Assist and AF Area.

Menu startWhen ‘Menu’ is selected, there’s now the option to display either the main menu screen or the last parameter set. This simplifies quick readjustment of recently-selected functions and settings.

MF AssistAn enlarged image portion can be displayed on screen with user-selectable duration while in MF (Manual Focus) Assist mode. MF Assist operation has also been improved. The previously-chosen magnified image portion can now be maintained when MF Assist is re-selected, making repeated checks of fine focus quicker and more convenient.
