Packing a lighter APS-C or Micro Four Thirds body for a trip means the familiar full-frame focal lengths don't behave the same way — worth converting before deciding which lenses actually make the packing list.
APS-C travel kit: an 18-55mm zoom covers roughly 27-83mm full-frame-equivalent, a solid general-purpose range.
Micro Four Thirds travel kit: a 12-40mm zoom covers roughly 24-80mm equivalent for similar general coverage.
Tips for this niche
Check the equivalent focal length for a favourite full-frame lens before assuming the same number will feel the same on a smaller-sensor travel body.
A smaller-sensor kit's telephoto reach effectively increases — useful to know before packing an extra long lens that may not be needed.

Example scenario
Deciding whether to pack a 55-200mm lens alongside an APS-C body, converting shows it already covers roughly 83-300mm full-frame-equivalent — enough reach that a heavier full-frame-only telephoto lens can stay home.
Common mistakes
Packing lenses based on full-frame habits without converting. a 24mm 'wide-angle' habit from a full-frame kit is only moderately wide on APS-C — check the equivalent before assuming the same lens choices apply.
Not accounting for the telephoto benefit of a smaller sensor. a smaller-sensor camera can mean less telephoto reach is needed to get the same framing, potentially saving pack weight.
FAQ
Does a smaller sensor mean I need different lenses for travel?
Not different lenses necessarily, but the same focal length numbers behave differently — checking the full-frame equivalent helps decide what actually needs to go in the bag.
