Does a 16mm lens look the same on APS-C as on full-frame?

No — the same focal length produces a narrower field of view on a smaller sensor. A 16mm lens on APS-C looks roughly like a 24-25mm lens would on full-frame.

Crop Factor Calculator for Landscape Photography

Landscape photographers packing a lighter APS-C or Micro Four Thirds kit for a hike need to know what focal length actually delivers the wide field of view they're used to on full-frame.

Recommended settings

APS-C landscape kit: a 10-18mm lens gives a full-frame-equivalent field of view similar to 15-27mm.
Micro Four Thirds: a 7-14mm lens equates to roughly 14-28mm full-frame-equivalent.

Tips for this niche

Check the equivalent before buying a wide-angle lens for a smaller-sensor travel or hiking kit — the same focal length number means a narrower view than on full-frame.
Remember this only converts field of view, not depth of field or low-light performance, which follow different rules across formats.

Example scenario

Choosing a wide-angle lens for a lightweight APS-C hiking kit, converting a familiar full-frame 16mm favourite shows an APS-C equivalent of roughly 10-11mm is needed to match the same field of view — the actual number to shop for.

Common mistakes

Assuming a lens's stated focal length behaves the same across formats. a 16mm lens is genuinely wide on full-frame but only moderately wide on APS-C — check the equivalent before assuming a purchase covers your needs.
Conflating field-of-view equivalence with exposure or depth-of-field equivalence. these are separate, more debated conventions — this calculator only handles the framing conversion, not aperture or depth of field.
