Originally posted by tuco I was going to say that seagull shot is pretty incredible for manual focus. You'll no doubt have a better success rate with auto focus with shoots like those. You'll need 5 to 10 seconds to confirm focus with the green light indicator in a camera like a K-7 with manual focus lenses.
This is what manual focus guys do:
1. Set the distance of the lens to around 150' and try to predict subject at around 100' to 40' away.
2. when bird comes within range, raise the camera and fire non stop in burst the first second. Do not wait for focus confirmation that will be forever in fast subject. Most likely the first shots will be completely off
3. Then you focus in the 2nd second. Your turn of the focus ring is little at no more than 15% degree like the original image I posted at around 50 ft away. It is a lot more foolproof than autofocus as far as I manage.
Quote: Marc Sabatella Yeah, that's about how it works unless you turn *extremely* slowly.
Marc ..from around 150' (preset distance) to 40' there is only a 15% degree turn of the focus ring. That takes a split second. Brighter view finder of K7 or K20 helps a lot for manual focus
