Product Information
Full details
The Samyang CF-77B is a 77mm replacement lens cap designed for photographers and videographers using compatible Samyang photo and VDSLR lenses. It serves as an essential accessory to protect your front glass element from dust, moisture, and potential scratches while your gear is in transit or storage. While it provides a reliable, secure fit for specified Samyang optics, users should verify their lens filter thread size before purchase to ensure compatibility with non-Samyang lenses.

FAQs
Will this fit any 77mm lens?
It is designed primarily for Samyang 77mm lenses. While it may fit other lenses with a 77mm thread, fitment is only guaranteed for compatible Samyang models.
Can I use this with a lens hood attached?
Yes, the center-pinch design is specifically meant to allow for easy access even when the lens hood is in place.
Is this cap weather-sealed?
It offers basic protection against dust and debris, but it is not a weather-sealed component and will not protect the lens from water intrusion.
How do I know if my lens is 77mm?
Look for a symbol on your lens that looks like a circle with a line through it followed by the number 77 (e.g., ø77).
Can I attach a lens cap leash to this?
The cap design does not have a dedicated anchor point for a leash, though some users find creative ways to adhere a leash clip to the side of the plastic.
Troubleshooting
Cap keeps falling off
Ensure the filter threads on your lens are clean and free of debris. If the lens threads are damaged, the cap may not seat properly.
Cap is difficult to attach
Check that no filters are currently stacked on the lens that might have damaged threads or extended beyond the 77mm standard clearance.

Setup, Compatibility & Care
To ensure proper fit, verify that your lens features a 77mm filter thread size, which is commonly marked on the front element or the side of the lens barrel with a circle-slash symbol (ø77). To attach, align the cap with the lens front and press the center tabs until it clicks into the filter threads. To remove, squeeze the center tabs inward. To maintain the cap, clean it occasionally with a soft, lint-free cloth to remove any accumulated dust that could transfer to your lens glass during re-attachment.
