Sony LAEA4 Lens Mount Adapter

donald from Titusville, FL on 2/19/2017

Crutchfield Customer Review (What's this?)

This adapter allows me to use a mount lenses on a full frame mirrorless body and produces best images I have taken with any of my glass. Camera body still balances well even with larger zoom lens and stabililzation is still excellent with A7m 2 body. Auto focus works very well in most instances with this setup.



Great tool for the Sony A7Mii

Crutchfield Customer Review (What's this?)

If you have A-Mount lenses and would like to use them on your E-Mount body, this is a "must have". It especially works well with the A7Mii, which as image stabilization built into the body. In use, the experience is similar to the one you get when you shoot with the Sony A99. The autofocus is fast and accurate, as long as you don't try to focus out on the fringes, since the focus points don't stray far from the middle area. Until Sony comes up with an adapter that uses their "4D" technology, this is the best adapter they make. You can use it with all the E-Mount bodies, but only the A7Mii will give you image stabilization, unless your lens has it (I think the only A-Mount lenses that has stabilization built in are some of the Sigma ones, but I have no experience with them). Lenses I have tried with it: Tamron 90mm Macro (the old design), Sony Zeiss 50mm 1.4, Sony 70-400mm G Mii, Sony Zeiss 24-70mm, and Tamron 70-200mm 2.8 USD.

Pros: Turns your E-Mount mirror-less camera into a translucent mirror camera and allows you to use A-Mount lenses. No image degradation that I can see.

Cons: No built-in image stabilization, unless you have the A7Mii (or any future models that might come with in-body stabilization). Also, with cameras like the A6000, you will not get some of the features available that you get with native E-Mount lenses, and will reduce the auto-focus areas (which will be concentrated more in the middle section).


Hands-on research

Product Research


Overview: The LA-EA4 mount adapter allows you to attach Sony Alpha α-series A-mount lenses onto Alpha α-series E-mount cameras. It is compatible with both full frame and APS-C cameras. The adapter has a handy tripod mount for use with larger lenses.

Compatibility: The LA-EA4 is compatible with all Sony α-series A-mount lenses, as well as the Sony α-series NEX and other E-mount cameras.

Translucent Mirror Technology: The LA-EA4 is the first full frame adapter to include Sony's exclusive Translucent Mirror Technology and Phase Detect AF sensor. The adapter allows your E-mount full frame camera to enjoy high-speed accurate TTL (through-the-lens) phase detection auto focus for both still and video capture.

Auto Focus: When the adapter is in use, Continuous and Single-shot Auto Focus is available, with a 15-point AF system and 3 cross sensors.

Auto Exposure Support: The adapter has an aperture drive mechanism and supports Auto Exposure with all A-mount lenses, except teleconverters.

Tripod Attachment: When using a tripod with the adapter attached, you mount the tripod to the LA-EA4 adapter. This is especially applicable when you use longer lenses (70-200mm, 70-400mm, 300mm, 500mm), as this will provide better balance, and help alleviate the load on the camera's mount.

1 question already asked

I need adapter for Vivitar 58mm lens to Canon EOS Rebel T6. [ DaVon  Nov 03, 2018 ]
Only if you purchase the proper Canon to Sony adapter. The Sony LAEA4 adapter is for mounting Sony A mount lenses to E mount cameras [ Robert  Jun 30, 2015 ]
The Sony LAEA4 is for using A-Mount lenses (Sony, Minolta, and 3rd party lenses) on an E-Mount camera like the A7II. If you want to use Canon lenses, you'll need a Canon to E-Mount adaptor. I believe Metabones is one of the companies that make such an adaptor. You'll want to check their website to see which ones may best meet your particular needs. [ Shunsuke  Jun 30, 2015 ]
A really confusing question - are you asking whether Sony lenses can be used on the Canon Rebel? And if this is your actual question, are you then asking whether the Sony LA-EA4 adapter could be used? Please note that the Sony LA-EA series of adapters is intended to ONLY adapt Sony A series lenses to allow them to fit Sony E series cameras. Nothing whatsoever related to Canon.
