Sony A6400 aps-c camera body and the Sony LA-EA3 Mount Adapter compatibility

Featured Replies

Hi folks..

I have a Sony A6400 camera which is an aps-c sensor mirrorless and up to now i have been using native e-mount lenses or canon ef-s lenses via a canon to sony e-mount adapter which has been fine.

I recently discovered that used Sony A mount lenses are even cheaper then used E mount.. but require the use of the LA-EA3 Mount adapter to step the A mount down..

My question is.. can i use this adapter on my aps-c A6400?

The Sony LA-EA3 Lens Adapter from Sony enables you to attach any A-mount lens to an Alpha E-mount full-frame digital camera body. It supports Auto Exposure (AE) and features an aperture mechanism.

I have asked at the shop where i was looking to buy this and they were not 100% sure and said to check on Sony forum as they would not accept liability for incorrect information given

The LA-EA3 works both on fullframe and APS-C cameras. What you should know is that the LA-EA3 only works on newer lenses with their own AF-motors (dedicated SAM/SSM). If you want to use older, screw-driven lenses, better get the LA-EA2 or LA-EA4 (same adapter except that the EA4 covers a fullframe image circle).

As Pieter says... but note that most A-mount lenses are bigger than the equivalent APS-C E-mount and even FF  E-mount lenses. (But then the saving in price might be the key factor - if you can get a top quality A-mount lens for the price of a lower quality  e-mount, why not?)

Also, be aware that "DT" lenses are specifically for cropped sensor cameras - and they are generally cheaper than the equivalent FF.

That would make sense as to why the description said for full frame e mount bodies...

Ah thats handy to know... i'll have to keep an eye out for the lens types then.... 

At least this has saved me buying an adapter without the right facts as the vendor at hand wasnt sure

I use the LA-EA2 oon my a6000. It is only for crop cameras, I believe.

Keep in mind that the A-mount lenses with a built-in motor are newer -- and will cost more than the older A-mount lenses without the built-in motor.  So if your goal is to reduce cost, stick with the older lenses -- which probably use the same optical formula anyway.
