Sigma 135mm f/1.8 DG (HSM) A (Art) Lens for Nikon {82}

Sigma's sharpest 135mm prime, built for full-frame portrait work.

The 135mm f/1.8 sits at a focal length that portrait photographers have trusted for decades, and Sigma's Art-line treatment gives it optical muscle to match. The 13-element, 10-group design incorporates a floating focus mechanism that keeps aberrations controlled across the focus range, not just at infinity. A 9-blade rounded diaphragm at f/1.8 produces subject separation that's difficult to replicate with slower glass, and the internal focus system means the barrel stays fixed while the HSM motor hunts quickly and quietly.

At 1,130 g, this is not a casual walk-around lens. The weight is the cost of that f/1.8 aperture in a 135mm package, and the 82mm filter thread reflects the front element's size. Weather sealing around the mount gives it real-world durability when light is best and conditions are worst. The focus distance limiter trims AF hunting on longer throws, and full-time manual override lets you refine focus without flipping a switch.

For what you get optically, a proven Art-series prime at a working telephoto length, capable of f/1.8 on full-frame Nikon F bodies, this lens sits well above its price point relative to first-party alternatives.

Who It's For

Portrait photographers shooting on Nikon F full-frame bodies will find f/1.8 at 135mm gives them subject isolation that f/2 or slower lenses simply cannot match at this distance. Event and wedding photographers benefit from the weather sealing and HSM autofocus when shooting in dim venues or unpredictable outdoor conditions. Sports and performing arts shooters working at mid-range distances gain from the internal focus and focus distance limiter, which keep tracking responsive. Film photographers looking for a cinematic telephoto prime will appreciate the 9-blade bokeh and manual focus override.

FAQ

Is this lens weather-sealed?

Yes. The mount has weather sealing, so it handles moisture and dust when you're shooting in challenging light and conditions aren't perfect.

What's the minimum focus distance?

0.88 m (about 34.65 inches). Close enough for tight portraits, though you won't do macro work at 0.2x magnification.

Does the barrel extend during focus?

No. Internal focus system keeps the barrel fixed, which helps with filter use and handling balance on longer throws.

Can I manually focus without switching modes?

Yes. Full-time manual override lets you refine focus by hand whenever you need it, no switch flipping required.

How fast is the autofocus?

The HSM ring-type ultrasonic motor hunts quickly and quietly. The focus distance limiter also lets you restrict the AF throw to tighten acquisition on shorter distances.

What size filters does it take?

82mm. The front element is substantial, so filter cost scales accordingly.

Is this lens heavy?

1,130 g (2.49 lb). That weight buys you f/1.8 at 135mm on full-frame, but you'll feel it on long shoots without support.
