Reading, UK - today, which rather surprised me to still see a flock of Swallows around. I find them really hard to photo - they notoriously don’t land, and fly fast, so this lot of photos is as good as I get.
Canon R6 + RF 800mm, 1/1250s, ISO 100 or 350 for these
I think what’s happening is the long focal length allowing distant shots is giving a much greater depth of being in focus, combined with decent sunlight, and often trees in the full frame that are the right sort of distance way (these are massively cropped down from the full frames). This gives a better chance of the auto-focus getting it right. Also, swallows do have slower glide phases in their flight which can help to get on target. What I was forgetting is to try burst shooting to up my chances.
Does burst have any negative effects on the quality?
Not that I’m aware of - just eats storage and battery! That said, with a heavy camera, you’re unlikely to keep it firmly on target for much of the burst!
