Compact Power: Samyang's New 85mm Lens Reviewed

Samyang has just released their compact AF 85mm f/1.8 P FE lens, and even though Sony users already have plenty of 85mm options, this one could actually matter. Instead of chasing the absolute sharpest glass, Samyang has built something different: a genuinely compact, lightweight lens with strong optical performance at a budget-friendly price.

Coming to you from Dustin Abbott, this detailed video examines what makes the Samyang AF 85mm f/1.8 worth considering. Abbott points out its unusually compact design—measuring under 3 inches in length and weighing just over half a pound—making it substantially lighter than its rivals. Compared to similar lenses like Sony’s own 85mm f/1.8, the Viltrox, or the Meike versions, the Samyang is significantly easier to carry. Additionally, despite its plastic build, Abbott appreciates the quality improvements, including sturdy weather-sealing, a precise AF/MF switch, and an updated lens hood that feels notably improved over previous Samyang offerings.

The lens doesn't skimp on features either, sporting a USB-C port directly on the mount for firmware updates. Autofocus performance is also solid thanks to a linear STM focus motor, providing responsive and reliable autofocus in real-world conditions, from spontaneous wildlife shots to casual portraits. Abbott even found good autofocus performance when adapting the lens onto Nikon bodies using a Megadap adapter, broadening its versatility.

Image quality is another standout. Abbott describes impressive sharpness and pleasing background blur, making this lens particularly appealing for portraits. He acknowledges minor issues, like noticeable focus breathing during video and some fringing under extreme conditions, but finds these manageable. The rendering and color balance lean slightly warm, something to consider when mixing brands.

However, the real question isn't just how well it performs—it's who it's for. Abbott believes the lens is ideal for users who value portability without sacrificing image quality, especially when travel or casual photography outweigh specialized portrait sessions. The combination of size, weight, and reliable performance makes it an attractive choice, particularly at its price point. Check out the video above for the full rundown from Abbott.
