  • Improves the AF response for situations where the distance of the subject changes considerably

  • Improves stability when operating the camera using the [Lens Compensation: Distortion] "Auto" and [Picture Effect] "Miniature" settings at the same time

  • Improves camera operations when using the [Exposure Compensation] and [Intelligent AF] settings

NEX-5N Firmware Update

Check your local Sony Support website to download NEX-5n Firmware 1.01 Update for Windows or Mac OS. Read the instructions twice before doing the update and make sure your battery is at 100%.

Unfortunately there is still no 7 shot exposure bracketing.

Thanks Mark R and Sony!


  1. Sorry for the double-post. I should have waited until I'd completed the update. It turns out that the Mac OS X updater is a 32-bit only application. If you're running OS X 10.7, you're probably in 64-bit mode by default and the updater will just tell you it can't run because of that.

    I hadn't run across this with any other application before. It turns out that you can boot to a 32-bit kernel by rebooting and holding down the 3 and 2 keys while you boot.

    Once I did that, the updater ran fine and my camera now displays the 1.01 version internally.

  2. Thanks for the information Orobros.

  3. Added a comparison video of the autofocus speed after the firmware version 1.01 update on the NEX-5N.

  4. 1.01 has apparently been withdrawn. Couldn't load it, and the tech had no idea that 1.01 even existed. Went to page and .05 is the latest!!

  5. I just downloaded and ran the update. 1.01 now.
