Quick answer
The SquareHood for Nikon Nikkor Z 40mm f/2 attaches directly to the lens's filter thread and is compatible with 52mm filters. Follow the steps below to install it securely and avoid cross-threading.
Why a square hood for a compact prime?
The Nikkor Z 40mm f/2 is a small, lightweight lens, and a square hood adds a distinct look while providing better flare protection than a round hood of similar depth. The SquareHood's anodised aluminium construction keeps weight low without feeling flimsy.
One trade-off: the square shape can make it slightly trickier to align when mounting compared to a round hood. The steps below focus on getting that alignment right the first time.
How to install the SquareHood on the Nikon Z 40mm f/2
- 1. Remove the front lens cap: Take off the standard Nikon 52mm lens cap from the Z 40mm f/2 so the filter threads are exposed.
- 2. Align the SquareHood with the lens threads: Hold the hood so its square opening faces forward. Gently place the rear thread ring against the lens's 52mm filter threads. Rotate the hood clockwise until you feel the threads engage. Do not force it — if it catches, back off and realign. Common mistake: starting at an angle. Keep the hood parallel to the lens face to avoid cross-threading.
- 3. Tighten until snug: Continue turning clockwise until the hood is hand-tight. Stop when you feel resistance — overtightening can damage the threads or the lens barrel. Checkpoint: the hood should sit straight and not wobble. If it feels loose, remove and rethread.
- 4. Attach the plastic cap (optional): Snap the included plastic cap onto the front of the SquareHood when storing the camera or when you don't need the hood's flare protection. The cap is plastic, so handle it gently to avoid cracking the clip tabs.
- 5. Use with a 52mm filter: If you want to use a UV, polarizer, or ND filter, screw it onto the lens first, then mount the SquareHood over it. The hood's rear threads are designed to clear standard 52mm filters. Stacking multiple filters may cause vignetting with the hood attached. Test your setup before shooting.
