Learn how to choose the right NiSi 150mm graduated ND filters for landscape photography, with fit guidance and decision rules for the 150mm system.
Quick Answer
For most landscape shooters, a 150x170mm graduated ND filter is the sweet spot: it covers wide-angle lenses without vignetting and gives you smooth transitions. Choose the 150mm system if you shoot with lenses up to 82mm filter threads and want the flexibility to use square filters. If you already own a 95mm lens, consider the 95MAG magnetic system for faster attachment.
Why Choose the 150mm System?
The NiSi 150mm system is designed for photographers who need larger square filters to cover ultra-wide and wide-angle lenses without vignetting. The 150x170mm size is particularly popular because it provides a generous filter area while remaining manageable in the field. If you're using lenses with a front filter thread of 82mm or larger, the 150mm system is a solid choice—it's also a favorite among landscape photographers who want to use multiple filters stacked for long exposures.
Key Considerations for 150x170mm Filters
When selecting a 150x170mm graduated ND filter, pay attention to the transition type (hard or soft), the strength (in stops), and the filter material. Hard transitions suit seascapes where the horizon is sharp, while soft transitions work better for rolling hills or mountain scenes where the horizon is uneven. Also, consider the filter's neutral color performance—full spectrum ND technology minimizes color cast, which is crucial for keeping your skies and foregrounds natural.
Another practical point: the 150mm system requires a compatible filter holder and adapter ring. For instance, the NiSi 150mm filter system can be used on a standard 82mm lens via a step-up adapter ring, which makes it versatile if you own multiple lenses with different thread sizes.
Magnetic vs. Traditional Holder Systems
If you're tired of screwing and unscrewing filters, the JetMag Pro magnetic system offers a quicker workflow. The 95MAG magnetic filters attach in seconds, and the patented locking design keeps them secure during shooting. However, the 150mm system traditionally uses a holder with slots, which gives you precise control over filter position—especially important for graduated filters where alignment matters. Both approaches have merits: magnetic for speed, holder for precision. Consider which workflow suits your shooting style.
Decision Rules for Choosing Your 150mm GND
- Lens Thread Size: Check your lens's front filter thread. If it's 82mm, you can use the 150mm system with a step-up adapter ring. If it's 95mm, you may need a dedicated holder or a magnetic system. Know your thread size before buying—it determines your adapter needs.
- Transition Type: Choose hard transition for sharp horizons (seascapes, city skylines) and soft transition for uneven horizons (mountains, forests). Some filters offer a medium transition for versatility. Match the transition to your typical shooting scenes.
- Filter Strength: Consider the stops you need. A 3-stop (0.9) GND is great for sunset skies, while a 10-stop ND is for long exposures. Graduated filters usually come in 1-3 stops; pick the range that matches your most common scenarios. Start with a 3-stop GND if you're unsure—it's a versatile choice.
- System Compatibility: Decide between traditional holder systems and magnetic systems. Holders offer precise positioning; magnetic systems offer speed. Ensure your chosen filters and holder are compatible. Your workflow preference should guide this choice.

The glow-in-the-dark markings are a small but handy touch when you're working before sunrise or after sunset.
Fit Guidance
Best for
- Landscape photographers using ultra-wide lenses who need to avoid vignetting
- Shooters who prefer the precision of a slot-in holder for graduated filters
Not for
- Photographers who prioritize speed and convenience over filter alignment—consider a magnetic system like the JetMag Pro 95MAG instead
