What does the LA-EA3 A-Mount to E-mount Adapter do?
The LA-EA3 lets you use A-mount lenses on E-mount camera bodies, providing electronic aperture control and auto exposure support. It does not include a translucent mirror, so image formation happens entirely on the camera sensor.
Does the LA-EA3 support autofocus with all A-mount lenses?
The LA-EA3 provides autofocus only with SSM and SAM lenses that have internal AF motors. It cannot drive screw-drive (motorless) A-mount lenses, since it has no built-in AF motor.
How much does the LA-EA3 A-Mount to E-mount Adapter cost?
MSRP is listed as $199.99. Given that, these models can go on sale from time to time, and there are several other opportunities to save on price like through their group discounts for education, healthcare and military/veterans (ID.me & Unidays) along with their free loyalty program that gives up to 5% back in points.
What is the difference between the LA-EA3 and the LA-EA4?
The LA-EA3 relies on the lens's internal motor for autofocus and has no translucent mirror, so it only supports AF with SSM/SAM lenses. The LA-EA4 includes a built-in AF motor and Translucent Mirror Technology, enabling autofocus with a wider range of A-mount lenses, including screw-drive lenses.
Can I use full-frame A-mount lenses on my full-frame E-mount camera with the LA-EA3?
Yes, full-frame A-mount lenses can be used on full-frame E-mount cameras with a compatible adapter like the LA-EA3. The lens still covers the full-frame sensor, though autofocus support depends on the specific camera and lens combination.
Which cameras work best with the LA-EA3?
The LA-EA3 is preferred on certain bodies such as the Alpha 7 II, Alpha 7 III, Alpha 9, A6300, and A6500 when using SSM/SAM lenses, because it uses the camera's own phase-detection AF system and avoids a translucent mirror.
Does the LA-EA3 have a built-in autofocus motor?
No, the LA-EA3 does not include a built-in AF motor. It relies on the internal motors of SSM and SAM lenses for autofocus, and cannot drive motorless screw-drive lenses.
Does the LA-EA3 come with a warranty?
Yes, the LA-EA3 includes manuals and warranty information, which can be accessed through Sony's support resources. You can also register your product and access firmware downloads through Sony's support pages.
