Sony LA-EA4 Adapter Review

The LA-EA4 makes it possible to use Sony A-mount lenses like the mighty ZA 1.8/135 on E-mount bodies like the Sony Alpha 7 or Nex-6 with full AF support and aperture control.

In this article I want to give an overview about its functionality and share my experience with it.

This adapter was loaned to me by Sony for this review.

The Adapter

LA-EA4

The Adapter is much bigger than adapters for manual lenses because it has to include an AF module, an AF motor and a second motor to control the aperture.

It replaces the older LA-EA2 which wasn’t full-frame compatible and it can be used with APS-C cameras like the Sony Nex-6 or a5000 as well as with full-frame cameras like the Sony a7.

The LA-EA4 uses Sony’s SLT technology, so a semitransparent mirror redirects a some of the light coming from the lens  to a AF sensor. This makes it possible to have liveview and fast phase detection AF at the same time. The cost for this is that 1/3 stop of exposure is lost so you have to compensate with a longer shutter speed or higher ISO.

The adapter is compatible with almost every A-mount lens made by Minolta or Sony from 1985 until today, the only exceptions are most Xi lenses and the Macro-Zoom, Sony  Australia has a list of incompatible lenses. 

It won’t work for older fully manual lenses which carry the MC or MD name tag. For those lenses check out my manual Minolta lenses post.

Carl Zeiss E 4/16-70 ZA OSS for Sony Nex Review

Introduction

The Carl Zeiss 16-70mm 1:4 made by Sony is an expensive standard lens for the Nex / APS-C E-mount line of cameras. It combines a very useful focal range with a decent moderate speed and size.

All in all I think it is an interesting lens but it has some weaknesses which will be a deal breaker for some photographers.

You can buy the Zeiss 4/16-70 at Amazon.com for $998or for 799€ at Amazon.de (affiliate links)
