Fotasy 72mm Metal Filter Stack Caps, Aluminum Alloy, Slim Fits

Quick take

Fotasy’s 72mm filter stack caps are a 2-piece set of slim aluminum caps designed to screw onto the ends of 72mm threaded filters so you can protect them while traveling and store them in a more streamlined way. They are a good fit if you carry multiple filters and want a compact, organized setup without bulky filter pouches. The main practical tradeoff is that thicker specialty filters may not stack together as easily.

Pros and cons

Pros

  • Aluminum alloy construction meant for durable, rigid protection
  • Screw-on design for securing caps in place while the filters are stored or transported
  • Slim 6mm stack-cap approach helps reduce bulk versus larger storage methods
  • Helpful for consolidating and organizing multiple 72mm filters in the field

Cons

  • Stacking convenience can be limited by filter thickness or how certain specialty filters connect
  • Only compatible with 72mm threaded filters (wrong size means it will not fit)

What buyers think

Reviewed productBuy on Amazon

Buyer review evidence points to strong satisfaction with the caps’ basic job: protection and compact organization. Multiple reviewers describe the caps as solid, sturdy, and well-finished, and they specifically call out that the threads go on and off easily. The most consistent “why this works” theme is that end caps help keep filters together and easier to carry compared with bringing a separate pouch, especially when you have several filters to manage during shoots. Overall, buyer feedback suggests a dependable, low-fuss solution for field storage, with limited discussion of performance issues because the caps do not involve complicated setup beyond threading them on.

What these filter stack caps do (and don’t do)

These are slim, metal end caps that let you protect the front and back ends of 72mm threaded filters. When you screw your filters together for transport, the top and bottom stack caps go on to cover the outer faces, aiming to reduce exposure to common handling risks like dust, scratches, and fingerprints. They also serve a practical storage role, helping you keep multiple filters grouped by size and contained in a smaller footprint for a camera bag or small case.

They are not a drop-in “filter case” with individual pockets for each filter. Instead, they are meant to work alongside your existing storage approach (for example, a small case, a filter holder you already have, or a compact way of carrying stacked filters).

Key specs that matter for buying

  • Fit size: 72mm threaded filters (and lenses with matching 72mm filter threads).
  • Material: aluminum alloy, built for rigid protection.
  • Design: 2-piece set (top and bottom) with a slim stack cap profile (6mm slim).
  • Use case: protecting filters when not in use, and organizing them while traveling.

Pros and cons for real-world use

Why they’re appealing

  • Compact organization: If you regularly carry more than one filter, end caps can make your kit easier to manage, especially in smaller camera cases.
  • Protection where it counts: Reviews emphasize protection for the “ends” of filters, which is exactly where handling damage and fingerprints often happen.
  • Screw-thread reliability: The threading action is repeatedly described as smooth enough for practical use.

Where buyers should be careful

  • Check your filter thickness: The stacking method assumes filters can connect in a way that the caps can still seat and align cleanly. Thicker or specialty filters may not stack as neatly.
  • Confirm thread size first: These are for 72mm. If your filters are 67mm, 77mm, or another size, the caps will not fit.

Who should buy these

These are a strong choice for photographers who:

  • Own multiple 72mm threaded filters (UV, CPL, ND, and similar).
  • Prefer a compact field setup over a bulky filter pouch.
  • Want an easier way to keep filters grouped and protected while not in use.

Who should skip them

You may want to look at a different storage approach if you:

  • Need individual compartments for filters (like a pocketed filter case).
  • Carry mostly mixed filter thread sizes and do not have enough matching 72mm filters to justify this kit.
  • Rely heavily on thicker specialty filters where stacking alignment is important.

Alternatives to consider (by storage style)

Reviewed productBuy on Amazon

If you are shopping for “filter cases” more broadly, your best alternative depends on what you want to optimize:

  • Pocketed filter cases: Better when you want each filter protected separately and easily accessible, at the cost of more bulk.
  • Hard plastic or roll-style filter holders: Useful for travel organization, especially if you do not like stacking threaded filters.
  • Dedicated lens-cap style solutions: Good for single-filter transport, but less helpful for organizing multiple filters together by size.

Verdict

The Fotasy 72mm metal filter stack caps are an effective, straightforward way to protect and organize 72mm filters when you are shooting on the go. Buyer feedback consistently highlights sturdy aluminum build, practical screw-thread usability, and the value of slimmer storage versus carrying a pouch. If your kit is mostly 72mm filters and you want compact, grouped transport, these are easy to recommend. Just make sure your filters and any thicker specialty options can stack cleanly for the workflow you want.

FAQs

Are these filter stack caps compatible with 72mm filters only?

Yes. They’re designed to fit 72mm threaded filters (and lenses with matching 72mm filter threads). If your filters are a different size, they will not thread on correctly.

How do they help with organizing filters?

They let you screw your filters together for transport and then cap the outside ends, which keeps multiple filters grouped and protected in a smaller footprint than bulkier storage options.

Do they work with all types of filters when stacking?

They work well for standard threaded filters, but stacking can be less convenient with thicker or specialty filters that may not connect as neatly. If your workflow depends on tight stacking, confirm your filter thickness and connection method first.

What protection are these caps meant to provide?

The goal is to protect the exposed ends of your filters while they’re not in use, helping reduce dust, scratches, and fingerprints during storage and transport.

Where do these fit in a filter storage setup?

They’re best as add-on end caps for stacked-filter transport. If you want a case with individual pockets and dedicated spots for each filter, you may prefer a pocketed filter case instead.
