The Canon EOS R6 Mark II with the RF 24-105mm F4 L IS USM is a full-frame travel kit that stays easier to pack than most f/2.8 zoom setups. Canon’s published body dimensions are 138.4 × 98.4 × 88.4 mm, and the RF 24-105mm F4 L is listed at 84 mm diameter by 107 mm long. That shorter lens length is why this kit clears many inserts and small shoulder bags that become marginal with larger telephoto kits.
The quick answer
For the smallest source-cited option in this dataset, start with the Tenba BYOB 10 Camera Insert. Its published 25 × 19 × 10 cm interior rates fits with room for the R6 II + 24-105 in our computed matrix. If you want a compact cube with a little more height, the WANDRD Essential Camera Cube also rates fits with room. If you want a sling instead of an insert, the WANDRD ROGUE 6L Sling is the small-bag pick from the current bag set.
What the computed table says
The table above runs this Canon kit against every active bag and insert we track. In the current source-locked dataset, 16 of 22 bags rate fits with room, 2 rate tight — measure carefully, and 4 exceed the published interior. That is exactly the useful pattern for a standard-zoom full-frame kit: most backpacks are easy, compact inserts are viable, and thin slings with shallow published depth still fall out.
Avoid treating litres as the answer. The Peak Design Everyday Sling V2 6L and the WANDRD ROGUE 6L Sling both carry a 6-litre label, but their published interiors are shaped differently. In this matrix, the WANDRD sling rates fits with room while the Peak Design 6L sling exceeds the published interior. Same nominal volume. Different box. The bag does not care about the marketing unit.
When to size up
If this is your only body and the RF 24-105mm F4 L is the main lens, a small insert or sling can be enough. Size up to a 20-litre backpack when you add a second body, a 70-200 class lens, flashes, or non-camera travel gear. For that larger carry, compare this page with the Sony A7 IV + 24-70 guide and the two-body travel backpack guide.
R6 II versus A7 IV carry size
The R6 II body is wider and deeper than the A7 IV, while this Canon 24-105mm F4 L is shorter than Sony’s 24-70mm F2.8 GM II in our source records. If you are choosing between the two systems for travel, the practical bag question is not brand loyalty; it is the mounted kit box. Use the camera comparator for body-level size checks, then use the fit checker when you want to swap lenses.
Every verdict here is computed from published camera, lens, and bag interior dimensions. It is a planning estimate, not a guarantee — padding, divider layout, and how you pack the lens hood can change the real-world feel.
