Focal length needed to frame it#
For a subject about 10 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) | 556 mm | 796 mm | 371 mm | 278 mm |
| 10 m (33 ft) | 1,112 mm | 1,593 mm | 741 mm | 556 mm |
| 15 m (49 ft) | 1,667 mm | 2,389 mm | 1,112 mm | 834 mm |
| 20 m (66 ft) | 2,223 mm | 3,186 mm | 1,482 mm | 1,112 mm |
| 30 m (98 ft) | 3,335 mm | 4,779 mm | 2,223 mm | 1,667 mm |
| 50 m (164 ft) | 5,558 mm | 7,965 mm | 3,705 mm | 2,779 mm |

Field-craft tips#
- Feeders and nectar flowers create predictable perches.
- Iridescent gorgets only glow when the bird faces the light — angle yourself toward the sun.
- A 1.4× teleconverter and minimum focus distance matter more than the longest lens.
- Pre-focus on a favourite perch or feeder flower and wait; their wings beat 50–80 times a second.
- Sightings peak in January, April, May, June, July and August, which is when you'll have the most chances.
- Tiny subjects: get close with a hide or feeder perch rather than cropping heavily.
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.
