Focal length needed to frame it#
For a subject about 18 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) | 318 mm | 466 mm | 212 mm | 159 mm |
| 10 m (33 ft) | 636 mm | 933 mm | 424 mm | 318 mm |
| 15 m (49 ft) | 954 mm | 1,399 mm | 636 mm | 477 mm |
| 20 m (66 ft) | 1,271 mm | 1,865 mm | 848 mm | 636 mm |
| 30 m (98 ft) | 1,907 mm | 2,798 mm | 1,271 mm | 954 mm |
| 50 m (164 ft) | 3,179 mm | 4,663 mm | 2,119 mm | 1,589 mm |

Field-craft tips#
- Bird-eye AF with continuous focus (AF-C/AI Servo); fill at least a third of the frame.
- Sightings peak in April and May, 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.
