Fotasy 55mm Metal Filter Stack, Aluminum Alloy Slim Stack Fits 55mm UV CPL Fader ND Filter
Quick take
Fotasy’s 55mm metal filter stack caps are a simple accessory for anyone who stores screw-in filters by stacking them. They use aluminum alloy caps to protect filter faces and help organize filters more compactly than bulk pouches, with the main caveat that they only apply to the 55mm filter thread size.
Pros and cons
Pros
- Aluminum alloy construction designed for slim, durable end-cap protection.
- Helps consolidate multiple 55mm filters into a more portable stack for travel and field use.
- Provides protection for filter ends from dust, scratches, and fingerprints while not in use.
- Screw-on threads are described as easy to attach and remove.
Cons
- Only compatible with filters that match the 55mm thread size (and intended stacking setup).
- Stack thickness can be a limitation for some specialty filters, such as thicker magnifying styles.
- No water resistance is indicated, so it is best treated as a dry-storage accessory.
What buyers think
Buyer feedback centers on the caps being a practical upgrade for filter organization and protection. Multiple reviews describe the metal build as sturdy and resistant to bending, and they highlight the “screw together” approach as convenient for consolidating filters in a small camera case. Reviewers also consistently mention improved organization, especially when filters are stored by size rather than mixed together, and they appreciate that the caps take up little space compared with bulkier storage solutions. The strongest caveats relate to fit for the exact filter size and to stacking behavior for thicker or non-standard filter types, with overall review evidence suggesting compatibility is excellent when the thread size and stacking expectations match.
What this is, and why it matters
This product is a set of top and bottom metal stack caps intended to protect filter ends when you are not using them. The general workflow is straightforward: screw your 55mm filters together into a stack, then cap the top and bottom so the glass and outer threads are less exposed to dust and fingerprints during storage or transport.
Instead of keeping each filter in a separate pouch, the stack-cap approach is meant to reduce clutter and make it easier to locate the filter you need when you are out shooting. That can be especially helpful if you carry multiple filters like UV, CPL, ND, or variable-style filters and want a consistent way to pack them.
Key specs and compatibility points
- Thread size: 55mm (made for filters with a matching 55mm thread).
- Material: aluminum alloy, designed to be slim and durable.
- What it protects: the filter ends while not in use, helping guard against dust, scratches, and fingerprints.
- Effective for: standard screw-in filters you can physically stack, then cap.
How it compares to other filter storage approaches
Stack caps vs. filter pouches or sleeves
Pouches and sleeves can be convenient, but they often increase the “search time” when you have several filters, and they may leave end surfaces more exposed. Stack caps trade a bit of setup effort (screwing filters together) for a more compact, organized carry style.
Stack caps vs. bulk filter cases
Bulk cases can be better when you want dedicated compartments for each filter. Stack caps are a strong option when space is tight and you mainly want end protection plus a predictable stacking system.
Pros and cons, translated into buying decisions
Who it’s best for
- You frequently carry multiple 55mm screw-in filters and want them organized in one place.
- You travel or shoot on location and prefer packing that stays compact inside a small camera bag.
- You want added protection for filter ends without switching to a larger, compartment-heavy case.
Who should avoid it
- You do not own (or plan to use) 55mm filters, because the caps won’t fit other thread sizes.
- You rely on thicker or specialized filter designs that may not stack cleanly with the rest of your set.
- You need a fully weather-sealed solution, since water resistance is not indicated.
Installation and day-to-day use tips
- Make sure your filter threads are aligned and fully seated before stacking, then cap the stack ends when you pack up.
- If you are carrying more than one filter, keep your stacking order consistent so the caps always thread on smoothly.
- For the most reliable protection, treat the caps as part of your storage routine (use them whenever the filter stack is not in use).
Price and availability
Availability can vary, so it’s worth checking the latest listing details before ordering. If you’re building out a 55mm filter kit, it may also be useful to confirm you have the right filter thread diameter across all filters you plan to stack.
Verdict
The Fotasy 55mm Metal Filter Stack caps are a good fit for photographers who want compact, metal-protected ends and a cleaner way to organize stacked 55mm filters. They look best as part of a system: if your filters match the 55mm size and you’re comfortable stacking, these caps can simplify packing and improve protection during transport.
FAQs
Are these filter stack caps compatible with all 55mm filters?
They are intended for 55mm threaded filters. Compatibility depends on your filters using the standard 55mm screw-in thread and fitting the stacking approach you use.
Do these caps work for stacking UV, CPL, ND, and fader filters?
Yes, they’re designed for stacking 55mm screw-in filters, which commonly includes UV, CPL, ND, and similar filter types, as long as the filters can be stacked and capped together.
Will these fit thicker or magnifying-style filters?
Thicker filters may affect stacking and connection. If your filter design is significantly thicker than typical screw-in filters, you may have limited stacking compatibility.
What do the stack caps protect against?
The caps are intended to protect filter ends when stored, helping reduce exposure to dust, scratches, and fingerprints.
Are they water resistant?
No water resistance is indicated, so treat them as a dry-storage and transport accessory rather than a weatherproof solution.
