The best materials for camera lenses are Cross-Linked Polyethylene (XLPE) and EVA (Ethylene-Vinyl Acetate) foam. Unlike standard open-cell polyurethane, XLPE and EVA are premium closed-cell foams. They are incredibly durable, highly shock-absorbent, and most importantly, they do not shed micro-dust particles that could scratch delicate optical glass or enter your camera’s sensor.

While pick-and-pluck foam is a cheap DIY solution, it degrades rapidly. Over time, the pre-scored cubes tear loose, causing heavy lenses to shift and bump into each other. Custom CNC or laser-cut foam from Foamkart provides a millimeter-perfect, permanent fit that holds its structural integrity for years, ensuring zero movement during transit.

For optimal shock absorption, you should leave a minimum of 0.75 to 1 inch (19mm – 25mm) of solid foam wall between heavy lenses or camera bodies. For the outer perimeter of the case, maintaining a 1.5-inch border is highly recommended to protect against exterior impacts, drops, and edge crushing.

It depends on the depth of your case and the size of the lens:

• Horizontal Storage: Best for heavy, long telephoto lenses (e.g., 70-200mm) to distribute weight evenly and prevent stress on the delicate lens mount.
• Vertical Storage: Ideal for shorter prime lenses and wide-angle lenses, as it maximizes the use of space in deeper travel cases.

Yes. Foamkart uses closed-cell foams which are naturally water-resistant and do not absorb moisture from the air, drastically reducing the risk of lens fungus. For ultimate protection in humid environments, we recommend requesting a small, dedicated cutout in your foam layout specifically for silica gel desiccant packets.

Absolutely. Whether you own a Pelican, Nanuk, SKB, Vanguard, HPRC, or an unbranded hard case, custom foam inserts can be precision-cut to match the exact interior dimensions, including specific corner radii and wheel-well protrusions.

To guarantee a perfect fit, gear is measured using its maximum dimensions (Length x Width x Depth). When measuring a lens, you must account for the widest points, such as the lens hood, tripod collar, and focus rings. Foamkart utilizes precision sizing to ensure every contour of your exact gear is accommodated.

No. High-quality XLPE and EVA custom foams are entirely non-abrasive and shed-resistant. They are engineered to be clean-room compatible, meaning they will not leave any particulate dust, lint, or chemical off-gassing residue on your camera bodies, lenses, or optical filters.

Yes, this is achieved through multi-depth routing. A single cutout can be stepped to different depths—for example, a deep cavity for a stack of ND filters, with a shallower shelf above it for SD cards or a lens cap. This maximizes the vertical space inside your camera case.

Because custom foam is a solid block cut exactly to your current gear, it cannot be easily “shrunk” to fit smaller gear later. However, Foamkart can design modular foam sections or multi-layered layouts. If you upgrade a specific lens, you can simply replace that specific module rather than buying an entirely new case insert.

Yes. When paired with an ATA-approved hard case, custom foam inserts are the absolute safest way to transport camera gear on an airline. The precision fit prevents the “shifting momentum” that causes internal damage during turbulence or rough baggage handling, keeping your calibrated optics perfectly safe.

As a general rule, the foam cutout should cover at least 75% to 80% of the item’s total depth. This ensures the lens cannot tilt or pop out of its cavity. The lid foam (usually convoluted/egg-crate foam) will then compress against the remaining exposed 20%, locking the lens firmly in place when the case is closed.
