Sigma Sigma Art Sigma 50-100mm f/1.8 DC HSM Art Lens for Nikon F Review
The Sigma 50-100mm f/1.8 is a specialist's dream: a zoom with prime-like speed. But its massive size and crop-only design make it a very specific tool.
The 30-Second Version
A unique, heavyweight champ for Nikon crop-sensor shooters. The f/1.8 zoom delivers stunning, sharp images with beautiful bokeh, but it's bulky and has no stabilization. Optical performance is top-tier (97th percentile). Worth it only if you need its specific superpowers.
Overview
Look, the Sigma 50-100mm f/1.8 is a bit of a weirdo, and we mean that in the best way. It's a zoom lens that acts like a bag of primes, offering a constant, super bright f/1.8 aperture across its entire range. That's rare, and for portrait and event shooters on Nikon APS-C cameras, it's a powerful tool.
Just know what you're getting into. This is a specialist lens, designed only for crop-sensor bodies. It's heavy, it's big, and it doesn't have stabilization. But if you're chasing that creamy background blur and need flexibility in low light, this is one of the few options that delivers.
Performance
The optics are the star here, scoring in the 97th percentile in our database. Images are sharp, and the bokeh quality is excellent for a zoom. That f/1.8 aperture is a genuine low-light monster. The autofocus is the main compromise; it's fine, but at the 46th percentile, it's not class-leading. It can be a bit noisy and isn't the fastest, so fast-action sports might be a stretch. And yeah, at nearly 3.3 pounds, it's a workout for your arms.

Value & Pricing
At around $1200, it's a significant investment. You're paying for that unique f/1.8 zoom capability and top-tier optics. If you're a dedicated portrait or event photographer on a Nikon APS-C system and you live for shallow depth of field, it's arguably worth it. For anyone else, the price and the heft are hard to justify when there are lighter, more versatile options.
Price History
vs Competition
This lens exists in a niche. Compared to a prime like a 50mm f/1.8, you get more flexibility but pay with size, weight, and cost. Against standard f/2.8 zooms, you gain a full stop of light but lose out on range, stabilization, and portability. The key trade-off is simple: unparalleled low-light zoom performance versus a lens you'll definitely notice in your bag. For Nikon APS-C shooters who need speed, it's basically in a class of its own.

Common Questions
Q: Will this work on my full-frame Nikon camera like a D850?
No, it's designed specifically for APS-C (DX) sensor cameras. Using it on a full-frame body will force a crop mode or cause heavy vignetting.
Q: Does this lens have vibration reduction (VR)?
No, it does not have any built-in image stabilization. Given its weight, using a monopod or tripod in low light is a smart move.
Q: Is the autofocus fast and quiet?
The HSM motor is decent, but our data shows AF performance is middle-of-the-pack. It's not the fastest or quietest system, especially for tracking action.
Who Should Skip This
Skip this if you shoot full-frame, need a lightweight travel lens, or rely on handheld video. Also, if you're just starting out, this much lens (and weight) is overkill. Look for a standard f/2.8 zoom or a fast prime instead.
Verdict
Buy this if you're a Nikon APS-C shooter (like a D500 or similar) who primarily does portraits, events, or low-light work and you absolutely need the flexibility of a zoom with prime-like aperture performance. It's a specialist's tool, not a walk-around lens.
