50mm vs 85mm Lens Comparison
Sensor Compatibility
The TTArtisan 50mm f/1.2 is designed for APS-C sensor cameras, while the Nikon 85mm f/1.8 targets full-frame sensors. This difference dictates which camera body you need. The TTArtisan mounts to Micro Four Thirds systems, making it suitable for Olympus and Panasonic cameras. The Nikon lens uses the Nikon Z mount. You must match the lens to your camera's sensor size and mount type. Using the wrong lens will not work. This is a fundamental hardware requirement. Your choice depends entirely on your existing camera system. One lens fits APS-C and M4/3, while the other is for Nikon Z full-frame bodies.
Maximum Aperture
The TTArtisan lens offers a wider maximum aperture of f/1.2. The Nikon lens has a maximum aperture of f/1.8. A lower f-number allows more light to enter the sensor. This helps in low-light situations without raising the ISO. The TTArtisan provides a two-stop advantage in light gathering. This can result in brighter images in dark environments. The Nikon lens still offers a large aperture for background blur. However, the TTArtisan gives you more flexibility in dim lighting. If you shoot often in low light, the wider aperture is a significant benefit. It allows for faster shutter speeds.
Build and Durability
The Nikon lens features dust and drip resistance with extensive sealing. This makes it suitable for harsh weather conditions. The TTArtisan lens has an all-metal body but lacks mentioned weather sealing. The Nikon lens weighs 1.04 pounds, while the TTArtisan weighs only 336 grams.

Focus System
Both lenses require manual focus operation. The TTArtisan is a manual focus prime lens. The Nikon lens also lacks autofocus in its description. You must adjust focus by hand for both. This requires practice and precision. The Nikon lens includes a customizable control ring. This ring can adjust aperture or other settings quickly. The TTArtisan does not mention a control ring. Manual focusing can be slower but offers full creative control. If you prefer tactile adjustments, the Nikon ring is useful. Both demand your attention for sharp images. Neither offers automatic focusing assistance.
Optical Features
The Nikon lens includes two ED glass elements and Nano Crystal coating. These reduce chromatic aberration and flare for better clarity. The TTArtisan lens has multi-layer coating and 10 diaphragm blades. It uses 7 elements in 5 groups. The Nikon optical design focuses on color accuracy and contrast. The TTArtisan emphasizes bokeh quality with its blade count. Both aim for sharp images with large apertures. The Nikon uses premium glass for professional results.
