Pick the Samyang 135mm f/1.8 if you need a longer telephoto reach and slightly brighter low-light performance at a marginally lower cost. The Sony 50mm f/1.4 ZA stays the better choice if you prefer a standard focal length for general use, portraits, or situations where a wider field of view is essential. Choose based on your subject distance and framing needs, as both deliver strong optical specs at similar price points.
