Comparing 2 standards across 9 specifications. 8 key differences identified.
Comparing:
77 mm Lens Filter Thread (M77 × 0.75)
82 mm Lens Filter Thread (M82 × 0.75)
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.
The 82 mm Filter Thread (M82 × 0.75 mm metric pitch) is the modern flagship standard for ultra-fast wide-angle and standard zoom lenses across full-frame mirrorless systems. Standard on the Sony FE 24-70mm f/2.8 GM II, Canon RF 24-70mm f/2.8L IS, Nikon Z 24-70mm f/2.8 S, and ultra-fast 50mm f/1.2 primes.
