Methodology
Every number is cited. Every verdict is a planning estimate from published dimensions — not a guarantee.
Where the numbers come from
- Cameras & lenses: manufacturer-published dimensions (body width × height × depth; lens maximum diameter × length, in millimetres). Where a manufacturer page is bot-blocked, we use a reputable mirror (dpreview, B&H) of the same figure and grade it retailer mirror.
- Bags: the interior compartment dimensions the maker publishes. We never infer interior size from exterior size. No published interior dimension means the verdict is unverified.
Every figure carries a source record with the URL, access date, and a verbatim excerpt.
How the fit is modeled
- Each gear item becomes a bounding box in millimetres — a body is
[width, height, depth]; a lens is a cylinder, so its box is[diameter, diameter, length]. - A bag compartment is a box
[interior width, interior height, interior depth]. Tapered inserts publish a depth range; we use the smaller depth to test physical fit and the average depth for capacity. - We subtract a small clearance (5 mm) from each compartment edge for padding and dividers.
- Individual fit: every item must fit the compartment in at least one orientation (rotation allowed).
- Capacity: we compare the kit's total bounding-box volume against the compartment's usable volume (its interior volume × a packing-efficiency factor of 0.62 that reflects real dead space between round lenses in a rectangular box).
The verdict scale
| Verdict | Meaning |
|---|---|
| Fits with room | Every item fits and there is comfortable spare capacity. |
| Tight — measure carefully | Everything fits, but with little spare room. Check against your exact gear. |
| Exceeds the published interior | At least one item won't fit, or the kit is larger than the compartment. |
| Unverified | We lack a published dimension we trust enough to compute a verdict. |
Why it is not a guarantee
Bags flex, dividers move, and manufacturers occasionally change interior dimensions between versions without renaming a product. We report from published specifications and do not measure every sample. Treat a verdict as a decision aid backed by the retailer's return policy. Our calibration is deliberately conservative, so borderline cases are called "tight" rather than "fits".
