Swallows are so challenging but such fun to shoot. The great reward is to capture that which is otherwise unseeable. By way of consolation, the Swallow doesn't always make the "shot" either:
And occasionally mistakes its target. Indeed if there is a wider "story" to tell, a looser crop is acceptable IMO:
Also:
My 2c on shooting these subjects:
- Shoot in good light
- Keep the sun at your back
- Shoot in wind if possible as it will slow the little beggars down some
- Don't expect a flight path remotely predictable. They turn on a dime at speed, sometimes dipping their tail into water to perform a handbrake turn when hunting insects on a body of water. This makes a charming image of itself
- Get into a "high speed" mindset. You are chasing them with your lens and trying to keep them in frame and in focus for a fraction of a second. The duration of the four frame sequences above is only 1/5 of a second (shot at 20 FPS) but that is all you need. You won't know what you have captured until you replay the sequence
- They are great to shoot as a video subject too if the AF tracking speed of your camera is fast when shooting video
- The higher FPS, the better. 30FPS and higher is ideal and the lower the FPS then the lower the probability of hitting the perfect timing.
- Start off with a relatively short focal length, 400mm on FF is good. This will get you accustomed to tracking at speed but you will find you will have to crop in post deeper than would like. Increase focal length as you get used to it. Modern well balanced primes which are not front-heavy makes light easier and more agile.
Good luck and enjoy the process.
