The New Sony XD Linear Lens Motor

You are here: Home / Technology / The New Sony XD Linear Lens Motor
Last updated: December 23, 2020 / Published: September 26, 2018 by Timothy Mayo - 2 Comments

Both the recently announced 24mm F1.4 G Master Prime Lens and the 400mm F2.8 GM Prime lens feature a new XD (extreme dynamic) linear lens motor.

Sony XD Linear Lens Motor

The XD Linear Motors have been newly developed to deliver higher thrust and efficiency than conventional types in order to make the most of the rapidly evolving speed performance of current and future camera bodies.

Two of these new motors are used in the SEL400F28GM, achieving up to a 5x improvement in moving-subject tracking performance. This means that the full speed performance of advanced camera bodies can be applied to capturing perfect images of the most dynamic sports or wildlife subjects.

The XD Linear motors are further supported by new algorithms developed specifically for them, notably improving the motors’ response to control signals and minimizing lag and instability that can occur when driving a large aperture focus lens group for quiet, low-vibration operation.

You can see how the new XD Linear Lens Motor works in this short video from Sony:

About Timothy Mayo

I started Alpha Shooters back in 2017 to share my own experiences as a photographer shooting with Sony Alpha cameras, lenses and accessories.

I enjoy wildlife photography the most but will happily point my camera at pretty much anything.

As well as this blog you’ll also find a community forum which provides members with a friendly and safe place to share images and ask questions.

You can find out more about my story here or follow me on Instagram if you wish.

I also have a YouTube Channel but haven’t published much content recently due to the demands of my one and three year old boys.

    Will this increased power and responsiveness in the new XD linear motor wasted if I am only shooting talking heads? I plan to shoot exclusively in continuous eye AF. I just purchased a Sony FX3 to videotape camera addresses and I thought I needed to wait till the new Sony F2.5 lens comes out because of it’s XD motor. Is that overkill?

      It will probably depend on how much the talking head is moving. If they are fairly static then the AF motors are certainly not going to be pushed to their limits. However, all of Sony’s latest GM lenses are now including these linear motors and some of the G lenses as well.
