Recommended camera settings#
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 |

Field-craft tips#
- Slow-moving in the canopy — patience pays.
- Use a small flexible zone or animal-eye AF; tiny birds flit constantly, so shoot short bursts.
- Sightings peak in April, which is when you'll have the most chances.
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.
