What fits, to scale

The tightest kit this bag still holds, drawn inside its interior compartment.

Packed-bag schematic FACE 21.5×17.0 cm face
R6 II24-70 f/2.8
98% of usable volume

Footprints overflow the drawn face — items would need stacking; see the volume figure.

Schematic, to scale. Footprints are real proportions; the fit verdict is computed by packed volume (62% packing factor), not this 2D layout.
