Samyang SY85M-P 85mm F1.4 Lens Pentax K Mount

The Samyang SY85M-P 85mm f/1.4 is a manual focus prime lens designed specifically for portrait photography on Pentax K mount cameras. Its optical formula uses 10 elements arranged in 7 groups to deliver the sharpness and contrast needed for detailed portraiture, while the fast f/1.4 maximum aperture creates the shallow depth of field and smooth background blur that define professional portrait work. The aperture range extends from f/1.4 to f/22, providing full creative control over depth of field and exposure in any lighting condition.

As a fully manual lens, the SY85M-P requires the photographer to handle both focusing and aperture adjustment by hand. The focus ring offers a smooth, well-damped throw that makes precise manual focusing practical, especially when combined with the camera's focus confirmation indicator or live view magnification. The 28.3-degree angle of view at 85mm provides the classic portrait perspective with flattering compression and comfortable working distance at the 3.3-foot minimum focus point. For Pentax shooters looking for an affordable, optically capable 85mm portrait lens, the Samyang offers a combination of speed, image quality, and build that is difficult to match at its price point, with the understanding that the fully manual workflow is part of the package.
