The FE 85mm f/1.4 GM II Lens: Faster, Sharper, Lighter

For anyone who’s serious about capturing detailed, crisp images with smooth, beautiful backgrounds, lens choice can change everything. This lens looks like a fantastic option.

Coming to you from Lee Zavitz, this straightforward video breaks down the Sony FE 85mm f/1.4 GM II lens. Zavitz demonstrates how this updated lens stacks up against the original 2016 model, highlighting noticeable improvements such as significantly faster autofocus and enhanced sharpness. Notably, Sony promises the autofocus is three times quicker, with tracking speed increased up to seven times, thanks to two XD linear motors. Zavitz tests these claims with real-world portraits, illustrating how these upgrades translate into better, more reliable shots, especially during movement and continuous shooting situations. The lens’ compact, lighter design (20% lighter than its predecessor) also means it’s much easier to carry around on shoots without sacrificing image quality or speed.

Beyond autofocus improvements, Zavitz dives into image quality by shooting portraits in challenging lighting scenarios, pointing out distinctive rainbow flares. Although improved lens coatings help reduce flare compared to the previous generation, some artistic flaring remains. Zavitz explains why this can be both a benefit or drawback, depending on your shooting style. He suggests using the included lens hood if flare isn't your style. Throughout the shoot, Zavitz emphasizes real-world scenarios, giving practical examples rather than lab tests, which makes the demonstration particularly helpful if you’re thinking about upgrading.

Zavitz also compares the new Sony lens with the popular Sigma 85mm f/1.4 lens, which he previously favored due to its affordability and better autofocus speed compared to Sony’s first-generation lens. Now, with Sony’s significant upgrades, the choice between the Sigma and Sony lenses has become less clear-cut. Zavitz hints at how these technical improvements might influence his own decision to switch lenses, making the video relevant if you’re currently using third-party alternatives and considering upgrading to native Sony glass.

The demonstration involves plenty of varied shots, each showcasing the lens’ real-world performance. Zavitz particularly highlights how the improved tracking is evident during continuous autofocus scenarios. Even though he's using a camera with relatively modest frame rates, Zavitz confidently notes that pairing the lens with something faster would unlock its full potential. Check out the video above for the full rundown from Zavitz.
