Pentax F* 300mm f/4.5 BIF Practice Shots

2009-05-04

Though I have problems getting close to the birds, I have been using my Pentax F* 300mm f/4.5 for birds in flight shots. If I manage to practice more, the results will be better. These are taken quite far away and cropped down and lighting is too dim around 7:00pm after work, hence the lost of detail. But I have the most fun with the mallard pair as I enjoy seeing them gliding in pair.

In high shutter speed, having SR off seems to do okay for me and the AF.C is working quite well for the shots as long as I manage to get AF in the panning the first moment that I see the birds approaching. I would like to get closer to the birds and I think with practice and more trials, I would learn to find a better location and find a better lighting as in blue sky and well lighted scene. More to come from another day with better lighting.

Another set is from a previous day with better lighting. Again in sunset lighting around 7:00pm. I may have the wrong setting as I pushed ISO too high in 1000 and I think I forget to turn SR off

Impressions & Notes

  • When shutter speed is over certain shutter value such as 1/1000 of a second, it seems that turning SR off has more benefits than turning SR on. The sudden movement in panning can trigger overcompensation from SR resulting in double edge pattern in the wings.
  • I love the F* prime for its compact size and weight and it allows me to be mobile and move my position as close to the birds in flight as possible
  • I need to learn about the mallard's pair gliding pattern, I find it the easiest to shoot them when they are not flopping their wings but gliding along their flight path
  • The initial AF confirmation is important for AF.C to work.
  • When I first see the sight of the bird, I tried to aim and half press and pan the bird movement hoping it is in an obvious direction and get 1, 2 or 3 shots out of the panning
  • I have used exclusively on AF.C with center focus and pan for the movement in a series.

I have used exclusively on AF.C with center focus and pan for the movement in a series.Hin, when shooting birds against a monotone sky, I think it might be better to use Auto Select Focus Point. The only things with enough contrast to trigger the AF will be the birds, and it's easier to follow them when you don't have to worry about having a bird right in the center of the FoV all the time. If it's just one bird, then it might not matter that much, but when you have two or more birds, it might happen that you have no bird in the center, in which case being able to use one of the other focus points automatically is crucial.

Mis, thanks for the comments. I have used the Auto Select Focus Point to a less degree of less success when I tried it on shooting puppies. I would try it again on BIF. Thanks! It it a logical thing that I should keep trying.
