Filter Size : 77mm (P = 0.75 mm) but it definitely usurped by lenses like the Z 70-200 f2.8 S and Z 24-70 f2.8 S. Still, at this price point, I would recommend Nikon users to go for this lens The NIKKOR Z 40mm f/2 is so compact and lightweight—just 1.8 inches long and weighing 6 oz—you'll forget it's even there. It doesn't extend or retract, so it's always ready. Take it wherever you go as your main walk-around lens or as a lightweight second lens. Mount: Nikon Z. Filter size: 82mm. Max aperture: f/2.8. Maximum magnification: 0.22x. Dimensions: Approx. 89x126 mm. the NIKKOR Z 24–70mm f/2.8 S is perhaps lighter than expected. At the NIKKOR Z 28-75mm f/2.8: 67mm: Polarizer | UV/Haze | ND: NIKKOR Z DX 50-250mm f/4.5-6.3 VR: aKtBI.
