Fotasy 77mm Metal Filter Stack Caps, Slim Aluminum Alloy Stack
Quick take
Fotasy’s 77mm metal filter stack caps are slim aluminum end caps that screw onto your 77mm filters to protect the glass surfaces and help you consolidate filters in the field. They’re a good match if you already use threaded 77mm UV, CPL, or ND filters and want a more compact carry setup. The main caveat is fit and stacking compatibility, especially with thicker or unusual filter designs.
Pros and cons
Pros
- Made from aluminum alloy, built for daily carry and protection
- Screw-on system that’s designed to secure caps in place
- Helps consolidate multiple 77mm filters into a streamlined stack
- Designed to protect filter ends from dust, scratches, and fingerprints
Cons
- Only compatible with camera lenses and filters that use a 77mm filter thread
- Stacking may not work cleanly for thicker filter types (fit depends on the filters you own)
What buyers think
Buyer-review evidence points to practical, field-ready value: people like how the caps help organize and carry multiple filters without needing a bulky pouch. Reviews commonly describe the caps as solid and sturdy, and praise the threaded connection for being easy to install and remove. Buyers also mention that the end-cap approach can feel more compact for small camera cases, and that the caps pair well with existing threaded 77mm filters.
At the same time, review themes suggest the biggest limitation is real-world stacking compatibility. One recurring theme is that thicker or non-standard filters may not connect as neatly when stacked, which is more about filter design tolerances than the caps themselves. Overall, the feedback is focused on storage convenience, protection during transport, and how well the threading works with matching 77mm filter threads.
How these filter stack caps work
This is a simple screw-together system meant for 77mm threaded filters. You stack your compatible filters together, then use the provided top and bottom metal caps to cover both ends. The goal is to keep filter surfaces protected while you’re traveling or moving between shots, while also reducing how much separate storage space you need.
Who these are best for
- Photographers who already own multiple 77mm filters (UV, CPL, ND) and want to carry them as one compact unit.
- People who prefer slim, metal protection over soft pouches or bulky hard cases.
- Anyone organizing gear in the field, where it’s easy to lose track of filter sizes and types.
Who should avoid them
- If you do not use 77mm filter threads, these caps will not fit correctly.
- If your filter lineup is mostly thicker or unusual designs, you may find stacking less convenient, since not every filter will connect seamlessly in a tight stack.
Pros and cons in real buying terms
Protection and build
The caps are made from aluminum alloy and are intended to shield the filter ends from common transport risks like dust and scratches. The most consistently praised feature in buyer feedback is the sense of sturdiness, with many reviewers emphasizing that the caps stay solid rather than flexing in-hand.
Convenience for carrying multiple filters
Where these caps stand out is consolidation. Instead of packing each filter individually, you can screw filters together and cap the ends. Reviews often frame this as a practical upgrade for small camera cases, particularly when you want everything grouped by filter size and ready to grab quickly.
Compatibility tradeoffs
Because this relies on threading and stack thickness, your results depend on the filters you own. If you use thicker filter designs, you may run into reduced stacking compatibility. If your kit includes multiple filter types, it’s worth checking how they connect before relying on a perfectly neat stack.
Price and availability
Pricing varies over time, and availability can change quickly. If you’re ready to pick up the set for your 77mm workflow, check the latest price and stock status at the link below.
Alternatives to consider
- Hard filter cases (by size): Better if you want guaranteed protection and easy separation of filters, especially when stacking may be awkward due to thickness.
- Filter pouches: More flexible for mixed filter sizes and shapes, but typically less organized and less compact for quick-grab setups.
- Different end-cap styles or stacking systems: If you frequently stack thick filters, you might prefer a system designed for tighter clearance tolerances.
Verdict
Fotasy 77mm metal filter stack caps are a strong choice if you want compact, screw-on end protection for 77mm UV, CPL, and ND filters and you like the idea of carrying filters as a single streamlined stack. If your filters are mostly standard and threaded, they should fit neatly into a mobile kit. If you use thicker, less stack-friendly filter designs, consider a storage option that doesn’t rely on stacking for fit and organization.
FAQ
Will these caps fit my lens or filters?
They are made for the 77mm filter thread standard. They should only be used with 77mm threaded filters and compatible lens filter threads.
Are these caps only for UV, CPL, and ND filters?
The intended use is for UV, CPL, and ND filters with matching 77mm threads. As long as your filters are threaded for 77mm and can be stacked, they should be compatible.
Do thicker filters stack well with these caps?
Stacking depends on your filter thickness and design. Some thicker or non-standard filters may not connect as neatly in a tight stack, so check how your specific filters thread together.
Do they protect against fingerprints and dust?
The caps are designed to protect the filter ends while the filters are not in use, helping reduce exposure to dust, scratches, and fingerprints during transport and storage.
Are these better than a filter pouch?
If you want a more compact, consolidated carry method for multiple 77mm filters, stack caps can be more convenient. If you prefer separating each filter or your filters are difficult to stack, a dedicated hard case or pouch may be a better fit.
