Lens Case Guide: How to Store 3 to 8 Lenses Safely

A good lens case holds each lens in its own snug foam pocket, caps on, with at least 20 mm of foam around it, inside a sealed hard shell. For three to eight lenses the easiest layout is upright, mount down, in a tall case like the Vantage 230, 260 mm deep inside. Standing lenses upright fits more of them in less floor space, and any one lifts out alone. Below: how to measure, maker sizes for common lenses, and how many fit.

Why lenses need more care than bodies

A camera body is dense and compact. A lens is a tube of glass elements held in precise alignment, often with a long barrel and a heavy front group. That creates three specific risks:

• Knocks to the front element or mount. A lens rolling against another lens, or against a case wall, chips the front glass or dents the mount.
• Side impacts on long barrels. A 70-200 lying loose takes a sideways hit along its whole length.
• Fungus. In a humid Indian monsoon, fungus can take hold on lens elements. A sealed case keeps rain out but also keeps humidity in.

The fix for the first two is a fitted pocket for every lens. The fix for the third is dry storage, which we cover at the end.

Upright or flat?

There are two ways to pack lenses in a hard case:

• Upright, mount down. Each lens stands in a round pocket. You see every lens from above and pull out one without lifting others. This needs a deep case, and the depth must cover your longest lens.
• Flat, lying down. Lenses lie side by side, usually alongside a body. This suits shallow cases and kits that mix bodies and lenses, but each lens takes more floor space.

For a dedicated lens case, upright wins. The Vantage 230 is built for it: 400 x 230 mm of floor space and 260 mm of depth, split into a 212.5 mm base and a 47.5 mm lid. For a combined body and lens kit, a flatter case such as the Vantage 270D or 350 usually works better.

How to measure a lens for a case

You need two numbers per lens: maximum diameter and length. Take them from the manufacturer's specification page, then check the real lens:

1. Length as it travels. A published length may not include the front and rear caps. Fit both caps and measure again with a steel rule, since that is the length the pocket has to hold.
2. The hood. A reversed hood can add to the diameter. Either measure the lens with the hood reversed or plan a separate flat slot for hoods.
3. Zooms that extend. Some zooms are longer at one end of the range. Store them at the shortest setting and measure there.
4. Add 40 mm. 20 mm of foam on each side, and 20 mm between neighbouring lenses. For upright storage, add 20 mm under the lens and 20 mm above it.

Maker's sizes for common lenses

These figures come from Canon's and Nikon's own specification pages. Diameter x length, in millimetres. The last column checks whether the lens stands upright in the Vantage 230 with 20 mm of foam above and below (length plus 40 mm, against 260 mm of depth).

The Nikon Z 70-200 is the useful edge case. At 220 mm long it needs exactly 260 mm with foam, which leaves nothing for the caps. Lay it flat along the 400 mm length of the case instead: 220 + 40 = 260 mm long and 89 + 40 = 129 mm deep, which fits easily.

Shooting Sony, Fujifilm or another system? Take the diameter and length from the maker's specification page for your exact lens, then measure it with caps on. Do not rely on sizes from memory or from a reseller listing.

How many lenses fit: three worked layouts

All of these use the Vantage 230's 400 x 230 mm floor with 20 mm of foam at every wall and between every lens.

Three f/2.8 zooms plus four small primes

Row one: RF 24-70, RF 70-200 and a third zoom about 89 mm across. 20 + 89.9 + 20 + 88.5 + 20 + 89 + 20 = 347.4 mm, inside the 400 mm length. Row two: four RF 50mm F1.8 size primes at 69.2 mm. 20 + (69.2 + 20) x 4 = 376.8 mm. Across the case: 20 + 89.9 + 20 + 69.2 + 20 = 219.1 mm, inside 230. Seven lenses.

Three zooms plus three larger primes

Swap the small primes for Z 50mm f/1.8 S size lenses at 76 mm. Four in a row would need 404 mm, too long, so three fit. Across: 20 + 89 + 20 + 76 + 20 = 225 mm. Six lenses.

Eight compact primes

Two rows of four 69.2 mm primes: 376.8 mm long and 20 + 69.2 + 20 + 69.2 + 20 = 198.4 mm across. Eight lenses, with depth to spare, since the tallest needs only 80.5 mm.

These layouts are a starting point. Your real lenses, with caps on, decide the final count. The Hard Case Size Finder checks your list against every size.

Cutting upright lens pockets

Vantage cases ship with solid foam sheets, a snap-off foam cutter and convoluted foam in the lid. For round pockets:

• Stand each lens on the foam and trace around the widest point, usually the front or the focus ring.
• Cut slightly inside the line. Foam compresses, and a pocket that grips the lens lightly holds it better than one it drops into.
• Leave a solid floor. Keep at least 20 mm of uncut foam under every lens.
• Add a finger notch at the edge of each pocket so you can grip the barrel, not the front element.
• Let the lid foam do the top. The convoluted foam in the lid presses down on the lenses and stops them lifting.

For tools and technique, see how to cut foam for a camera case. If you want perfectly round pockets without cutting them yourself, ShutterBuzz makes custom laser-cut premium foam inserts on request.

Monsoon, fungus and long term storage

A Vantage case is IP67 rated: dust-tight and protected against immersion to 1 metre for 30 minutes. That keeps rain, splashes and dust off your lenses in transit. It also means whatever humidity you close inside stays there.

• Dry lenses before packing. After a humid or rainy shoot, leave lenses out with caps off in a dry room for a few hours.
• Use fresh silica gel in the case and replace or recharge it regularly.
• Do not use the case as a cupboard. For weeks between shoots in the monsoon, a dry cabinet with controlled humidity is the right home for lenses.

Frequently asked questions

Should lenses be stored upright or lying down?
In a dedicated lens case, upright, mount down, is the most space efficient and easiest to unpack. Very long lenses that exceed the case depth can lie flat.

Can I store lenses attached to the camera?
For a small lens, often yes, if the pocket supports both the body and the lens. For long or heavy lenses, remove them so the mount is not carrying the weight of the lens in every bump.

How much foam should be around each lens?
At least 20 mm on every side, including between neighbouring lenses, and 20 mm below.

Is a hard case enough to prevent lens fungus?
No. A sealed case protects lenses in transit. Fungus prevention needs low humidity, which means drying lenses before packing, fresh silica gel, and a dry cabinet for long term storage.
