Shimoda Core Unit Filter Case (520-521)

Shimoda Core Unit filter pouch (520-521), compact filter protection directly in your Core Unit

In the middle of a shoot, the light changes, the clouds do their own thing, and you’re once again digging through your backpack looking for your filters. We all know this. This is exactly where the Shimoda Core Unit filter pouch (520-521) shows its strength: your 100 mm filters are right where you actually need them – directly in the Core Unit, neatly organized and instantly within reach.

Capacity for up to four 100 mm filters

The filter pouch offers space for up to four 100 mm filters. No more, no less – exactly the amount that usually comes along in practice: for example an ND, a strong ND, a GND and maybe a polarizer. Each filter lies separately in its own sleeve so they don’t scratch or jam against each other. This keeps the glass clear, even when conditions outside get a bit rougher.

Integrated filter storage in the Shimoda Core Unit

Especially practical: the Shimoda Core Unit filter pouch is designed so that you can attach it directly inside any Shimoda Core Unit. You simply open the lid of your Core Unit, place the pouch against the inner wall or a divider, and secure it with the hook-and-loop fastener. Done. No separate fiddling with additional pouches, no searching through random backpack compartments.

While you’re setting up your camera, the filters are immediately in your field of view without having to open any additional zippers. Everything is in one place, clearly laid out and logically arranged. And if you’re out without a full backpack: the pouch also works completely on its own, for example in a shoulder bag or simply in your hand when you’re traveling minimalist.

Easy and fast access in everyday photography

The designers really thought about access. With a single pull on the tab, the filter insert becomes visible. The movement is intuitive; you get used to it very quickly. A dedicated cut-out in the pouch lets you quickly grab each filter, take it out and put it back without any fumbling.

Packing is just as straightforward: place each filter back in its sleeve, press the tab down, and everything sits compact and secure again. Especially when it’s windy outside or time is short, this little bit of comfort makes a noticeable difference. You lose less time searching and spend more time shooting.

Dense and smooth protection for delicate filters

Filters are delicate – we all know that. That’s why the interior of the Shimoda Core Unit filter pouch is deliberately designed to be robust and at the same time gentle. The walls are made of dense EVA padding that reliably absorbs shocks and pressure. Compact on the outside, soft on the inside – a kind of protective cushion for your glass.

The padding is covered with a smooth, scratch-resistant tricot lining. This material feels pleasant but stays unobtrusive in the background so your filters don’t get scratched or snag. The fit is intentionally tight and compact to save space in your backpack while still providing excellent protection. Nothing wobbles, nothing rattles, everything sits securely.

Flexible use in the Core Unit or on its own

The filter pouch was designed from the ground up to work well both in Shimoda Core Units and as a standalone bag. In the Core Unit it’s essentially an integrated filter station: you set up your camera, reach straight for the filters and don’t have to switch back and forth between different bags.

Outside the Core Unit you can simply use the pouch as a compact filter bag. It fits easily into many camera backpacks, messenger bags or even smaller daypacks. This is especially convenient when traveling or shooting in the city: you only take the filters you really need and still have them well protected and neatly organized.

Practical handling while shooting

In use, the whole thing works surprisingly smoothly. You open your Core Unit, pull lightly on the tab, and the filters are immediately visible. The cut-out in the pouch helps you quickly identify each individual filter without having to take everything out. This makes removing and replacing them much easier, especially when you’re working with multiple filters or in changing light conditions.

This reduces the risk of a filter slipping from your hand or ending up somewhere in the grass. We all know those little moments of panic. With clearly structured storage like this, they can be noticeably minimized.
