Blackmagic Design Lens Cap 58mm
The Blackmagic Design Lens Cap 58mm is a protective front-element cover designed for lenses with a 58mm filter thread. While smaller than the cine-standard 77mm or 82mm sizes, the 58mm cap is a vital accessory for many "nifty fifty" primes and compact zoom lenses frequently used in lightweight Blackmagic Pocket Cinema Camera or gimbal setups.
Key Features
-
Snap-On Center-Pinch: The dual-action center-pinch design allows you to snap the cap into the lens threads or the front of a filter without having to remove the lens hood.
-
Precision Fit: Engineered with high-tension internal springs to ensure the cap remains seated even when the camera is jostled in a bag or slung over a shoulder.
-
Material: Made from high-impact, matte-black polycarbonate. It is designed to take the brunt of an accidental bump, protecting the much more expensive glass element underneath.
-
Branding: Includes the debossed Blackmagic Design logo, maintaining the professional "stealth" aesthetic of the Blackmagic ecosystem.
Common 58mm Lens Pairings
The 58mm size is extremely common among the lightweight glass often used with the Pocket Cinema Camera 4K (MFT mount) and Pocket 6K (EF mount):
-
Panasonic Lumix G X Vario 12-35mm f/2.8: A "must-have" stabilized lens for the Pocket 4K that uses 58mm filters.
-
Canon EF 50mm f/1.4 USM: A classic portrait lens for Blackmagic shooters.
-
Canon EF 85mm f/1.8 USM: A popular choice for tight interview shots.
-
Olympus M.Zuiko Digital ED 40-150mm f/4.0-5.6: A common compact telephoto for MFT users.
Operational Insight
In a professional workflow, 58mm lenses are often the choice for drone or gimbal work (like on a DJI RS3) because of their low weight. Because these rigs are often moved quickly between takes, the lens cap is frequently taken off and put back on to protect the glass from dust and debris kicked up by fans or wind.
Why It Matters
Using a genuine Blackmagic cap ensures that the "grip" of the pinch mechanism is deep enough for the lens threads. Many generic 58mm caps are too shallow, causing them to pop off if they graze the side of a camera case. For a filmmaker, a lost cap usually leads to a scratched lens or a dirty front element—both of which can cause unwanted "flaring" or "softness" in high-resolution 4K or 6K footage.
