67 mm Lens Filter Thread (M67 × 0.75)
Direct Answer
The 67 mm Filter Thread (M67 × 0.75 mm metric pitch) is the dominant standard for compact full-frame f/4 professional zooms, medium telephoto portrait primes (85mm f/1.8, 135mm f/2), and Tamron's mirrorless lens lineup (28-75mm f/2.8, 17-28mm f/2.8, 70-180mm f/2.8), allowing unified filter sharing.
