Comparing:
72 mm Lens Filter Thread (M72 × 0.75)
77 mm Lens Filter Thread (M77 × 0.75)
The 72 mm Filter Thread (M72 × 0.75 mm metric pitch) is an intermediate lens thread size widely used for telephoto f/4 zoom lenses (Canon/Nikon 70-200mm f/4), fast 35mm and 85mm f/1.4 primes, and versatile all-in-one enthusiast zooms (Nikon 24-120mm f/4, Sony FE 70-200mm f/4 G).
The 77 mm Filter Thread (M77 × 0.75 mm metric pitch) is the legendary professional zoom lens standard across Canon L-series and Nikon pro glass for over three decades. Benchmark for 70-200mm f/2.8 telephoto zooms, older 24-70mm f/2.8 zooms, and 16-35mm f/4 ultra-wide zooms.
