Sony Unveils New A-Mount to E-Mount Adapter with Built-In AF Motor

In a surprise announcement this morning, Sony unveiled the new LA-EA5 lens adapter: a Sony A-mount to E-mount adapter that promises E-Mount autofocus and burst shooting performance when using Sony’s older A-mount glass, including lenses without a built-in AF motor.

The LA-EA5 is a surprisingly compact adapter, given everything it’s promising. The adapter allegedly delivers “full support” for focal plane phase-detection AF, wide-area focal phase-detection AF coverage, real-time Eye AF for both humans and animals, and real-time Tracking and AF/AE tracking for SSM/SAM lenses at up to 11fps depending on the camera model you’re using.

Additionally, the adapter actually features a built-in AF drive, allowing you to get these same capabilities when using older lenses that don’t have internal focus motors of their own.

This is quite the feat of engineering—a fact that becomes obvious as soon as you set this adapter next to the previous LA-EA4:

Sony is working to expand compatibility for this adapter, but as of September 2020 supported cameras include:

• Sony a7 III
• Sony a7R III
• Sony a7R IV
• Sony a9
• Sony a9 II
• Sony a7s III
• Sony a6100
• Sony a6400
• Sony a6600

Note that the ability to use lenses without internal focus motors is only available when using the Sony a7R IV or a6600.
