Sirui Sniper 23mm f/1.2 Autofocus Review

This lens has one job: to make your APS-C Nikon Z camera look like a low-light monster. The Sirui Sniper 23mm f/1.2 is an ultrafast wide-angle prime that gives you a classic 35mm full-frame equivalent field of view. Forget versatility. This thing is a specialist, and it's built for portraits and creative work where you want that shallow depth of field and buttery background blur. Just know going in that it's not a travel lens, and the autofocus isn't winning any races.

The performance is exactly what you'd expect from a lens with a 96th percentile aperture rating. It's incredibly bright, and the bokeh is genuinely beautiful, landing in the 95th percentile. That f/1.2 aperture lets you shoot in near-darkness and get that dreamy separation. What surprised me, honestly, was the autofocus. It's functional, but at the 48th percentile, it's just okay. It hunts a bit in low contrast, and you won't be relying on it for fast action. For portraits and slower-paced video, it's fine, but don't expect Sony-level tracking.

At around $279, this lens is a steal for what it does. You're getting f/1.2 performance at a fraction of the cost of native glass. If your priority is creative shallow depth of field and low-light capability on a budget, the value is through the roof. Just temper your expectations on the autofocus.

The most direct competitor is the Viltrox 35mm f/1.7 for Nikon Z. It's a similar focal length (actually a 52mm equivalent) and price. The Viltrox has slightly slower autofocus but is also sharper in the corners. For a wider option, look at the Sony 15mm f/1.4 G for E-mount (via adapter), but you're paying more for better build and AF. The Sirui wins on pure speed and bokeh quality, but the Viltrox is a more balanced, versatile daily driver.

Buy this lens if you shoot a Nikon Z50, Z30, or Z fc and you live for creamy bokeh and shooting in dim cafes or at dusk. It's a fantastic creative tool that punches way above its price. But if you need reliable, snappy autofocus for kids or pets, or you plan to upgrade to a full-frame Z camera someday, look at the Viltrox or save up for a native Z lens. For the right shooter, this is an easy recommendation.
