Focal length needed to frame it#
For a subject about 14 cm long filling a third or half of the frame width horizontally. Small birds demand long lenses and a close approach — a blind or feeder setup helps.
| Distance | ⅓ of frame (FF) | ½ of frame (FF) | ⅓ of frame (APS-C) | ⅓ of frame (MFT) |
|---|---|---|---|---|
| 5 m (16 ft) | 404 mm | 588 mm | 270 mm | 202 mm |
| 10 m (33 ft) | 809 mm | 1,176 mm | 539 mm | 404 mm |
| 15 m (49 ft) | 1,213 mm | 1,765 mm | 809 mm | 607 mm |
| 20 m (66 ft) | 1,618 mm | 2,353 mm | 1,078 mm | 809 mm |
| 30 m (98 ft) | 2,426 mm | 3,529 mm | 1,618 mm | 1,213 mm |
| 50 m (164 ft) | 4,044 mm | 5,882 mm | 2,696 mm | 2,022 mm |

Field-craft tips#
- Very approachable at feeders — set up a natural perch near the feeder.
- Winter flocks make them easy to find.
- Bird-eye AF with continuous focus (AF-C/AI Servo); fill at least a third of the frame.
Ethics#
- The welfare of the animal comes first: if it changes its behaviour because of you, you are too close.
- Stay on trails, respect closures around nests, leks, dens and haul-outs.
- Avoid playback and baiting in sensitive seasons; never bait predators.
- Don't share precise locations of rare, nesting or roosting animals publicly.
