Samsung 85mm f/1.4 ED SSA T85NB NX

Samsung 85mm f/1.4 ED SSA T85NB NX

The Samsung 85mm f/1.4 is a beast of a lens, but not any larger than other 85mm f/1.4 lenses. How does this beauty perform?

Samsung has a nice set of pancake lenses that all measure about 62x22mm, but this lens is by no means a pancake, and flies in the face of the subtle and light paradigm of the NX system being one of the largest and heaviest lenses available, but it is also the largest aperture native NX mount lens.

The build quality is top notch for the NX series lenses. It is a mix of metal and plastics, has a built in distance scale, a well damped focus ring, which I will add is mechanically coupled (not focus by wire), a handy A/MF-MF switch, and a nice large hood.

The lens has 10 elements in 8 groups, with a 9 bladed, mostly circular, diaphragm. The minimum focus distance is standard for the class at 0.82 m (3.2 ft), and the weight is also fairly standard at a heavy 714 g (25.2 oz) without the hood. It uses fairly standard 67mm filters. The lens is very dense, but not terribly large for the class of lens.

Comments on the Results

The lens has good contrast and resolution across the frame at all apertures. I only have the uncorrected RAW data here, so don’t compare it to the other lenses corrected values (the camera applies more sharpening than Lightroom by default). Using it at f/1.4 and infinity you will notice some aberrations, but step down to f/2 or f/2.8 and it is just great. The level of detail resolved even at f/1.4 is great.

The lens has virtually no distortion.

Lateral CA is good, but noticeable at smaller apertures. It definitely isn’t a problem though. Longitudinal CA is typical for the class (fairly visible at large apertures).

Purple fringing is visible as with any lens with a fair amount of longitudinal CA. Average for this class of lens. Improves on stepping down the aperture.

Coma is minor and astigmatism is negligible. The bokeh circles are cats-eye shaped near the edge of the frame at large apertures.

Flare resistance is good for this class of lens. The coatings are extremely efficient at eliminate flares and the deep hood is hardly needed.

Measured focal length is 88mm at 1:53 magnification.

Pros and Cons

Bottom Line

This is a beautiful lens. The optical performance is excellent, it is sharp across the frame, doesn’t have any serious flaws in performance in any regard. The mechanically coupled focus makes manual focus feel decent, the distance scale on lens is a nice touch, but you can also get a distance scale visible in camera. Focus speed is good, but by design this style of lens is not super fast focusing (the focus throw is very long). The price is actually fair if you compare it to Nikon 85mm f/1.4G, and even compared to the older 1.4D or Sigma 85mm f/1.4 it is comparable in price. Buy this lens for head and shoulders portraits or general telephoto work because of its excellent overall performance. Buy the lens on Adorama to support the site. If they don’t have it in stock and you are in the US, you can usually order them anyway and it will show up in 3 weeks or so.

    The Lens is extremely veiastrle and can travel anywhere. If you own a Nikon DX camera like the D7000 or the D90, you should own this lens. This lens is great for beginners and well seasoned photographers with DX Cameras .a0 There are photographers who have used a Nikon 35mm f/1.8 DX lens on a full frame camera.
