Breakthrough Filters 2 Stop Soft GND 150x170mm - Colour Neutral Filter

Our review of the Breakthrough Filters 2 Stop Soft GND 150x170mm looks at who benefits most from this graduated neutral density filter and why its optical quality stands out. The bottom line: landscape and urban photographers who need a subtle, natural-looking transition will appreciate the filter's colour neutrality and sharpness. The tempered construction and 16-layer MRC protection promise long-term durability, while the included colour coded diamond case and 25 year manufacturer warranty make this an attractive buy for anyone who values long-term reliability in their filter kit.

Key Features

• Original tempered GND: The tempered glass construction offers structural strength and consistent optical performance for demanding field use.
• Worlds sharpest and most colour neutral: The filter preserves fine detail and avoids unwanted colour casts so skies and highlights render naturally.
• 16 MRC protective layers: Multiple coating layers form a harder surface that helps reduce flaring and protects the optical surface from abrasion.
• 99.4% light transmission: High transmission ensures retained image brightness and contrast when the neutral density is applied.
• Nanotec coatings: Water and dirt are repelled, making the filter easier to clean and maintain in wet or dusty conditions.
• Colour coded protective case: The individual diamond case helps identify and protect the filter while stored or transported.

Who It's For

The Breakthrough Filters 2 Stop Soft GND 150x170mm is aimed at landscape, seascape and cityscape photographers who use long exposures or want to balance bright skies with foregrounds. Its soft transition makes it particularly suited to scenes where the horizon is uneven or there are foreground elements that should not be heavily darkened.

Photographers who need extremely hard-edge transitions for architectural work or those who prefer inexpensive entry-level glass should look elsewhere; this product targets users who prioritise colour fidelity, sharpness and a durable protective finish over the lowest possible price.

Pros & Cons

Pros

• Exceptional colour neutrality keeps skies and highlights true to the scene without tinting.
• High-quality tempered construction and 16 MRC layers offer strong protection and reduced flare in challenging light.
• Nanotec coatings resist dirt and moisture, making field cleaning easier and preserving image quality.
• Included colour coded diamond case and a long 25 year manufacturer warranty provide extra confidence for long-term ownership.

Cons

• Soft transition GNDs are less suitable for scenes with a sharply defined horizon where a hard-edge GND would perform better.
• Higher-quality coatings and tempered construction mean a price premium compared with basic neutral density filters.
