Testing the LA-EA5 Lens Adaptor

Gustav Kiburg

The Sony LE-EA5 is a brand new adaptor, designed to maximise the use of A-mount lenses on the latest E-mount bodies, offering fast and accurate autofocus along with high speed continuous shooting.

Thanks to its built-in motor, it can even autofocus those A-mount lenses that don’t have one built in, while still taking advantage of the focal-plane phase-detection of the camera. All of this capability is concealed in a compact, elegant cylindrical design.

“I’ve been an avid Sony shooter for years, but having switched to E-mount bodies a few years ago, my old Alpha 99 II has been gathering dust in my cupboard. I’d amassed quite a few nice lenses over the years and although I’d gradually been replacing them as the E-mount system grew, there were a couple that I’d hung on to, in particular the 300mm f/2.8 SSM which was one of my favourite lenses for wildlife, and the 70-200mm f/2.8 G SSM II, which was always such a sharp lens. Naturally, I was very pleased when Sony asked me to test the new LA-EA5 adapter as it gave me an excuse to dust off my old lenses and see if they were as good as I remember them.

I’ve gotten so used to the focus speed of my Alpha 9 II and 7R IV using my FE lenses, but I was eager to see how the cameras would cope with my older lenses via the adapter. My first location was in a forest near the village of Hulst. It’s a favourite of mine and I’ve been many times to photograph the beautiful red squirrels that thrive there and I opted for the 300mm f/2.8 SSM mounted on my Alpha 7R IV. The first thing I noticed about the new adaptor is how small and comfortable it is – it doesn’t have the bulky underhang that the old adaptors have.

I positioned myself near a pond and it wasn’t long before the squirrels put in an appearance and once I’d fired off a few shots, I almost forgot that I was using an old A-mount lens – the focus speed and accuracy were superb. I wasn’t sure how the animal Eye-AF would work either, but it didn’t fail to pick up the squirrel’s eye, and every shot was tack sharp. I prefer to shoot hand-held as it gives me the flexibility to quickly reframe when the squirrels are active, and the in-camera stabilisation coped with any slight movements from me with ease.

A friendly bird also came down to the pond for a drink!

My next port of call was Rotterdam harbour. There are often many speedboats active on the water and I was keen to see if my old 70-200mm f/2.8 G SSM II would cope with focus tracking a moving subject.

As you can see I couldn’t fault the AF, and once it had locked on to the boat, it tracked focus accurately.

The last lens I wanted to try was my old Zeiss 16-35mm f/2.8 ZA SSM II which was a fabulous piece of glass. I must admit, I haven’t missed this as much because my G Master 16-35mm f/2.8 is so sharp, but I was enjoying using the adaptor so much, I wanted to see how it performed.

My overall experience using the LE-EA5 adaptor with my old A-mount lenses was extremely positive. All the lenses I tried reacted quickly and gave me precise focus, and what surprised me the most was the accuracy of the Eye-AF and AF tracking. For those photographers still sitting on their old A-mount lenses, the LE-EA5 is a worthy investment!
