Thanks again Joanne. The pictures I posted yesterday were fairly good and I am pleased with them.
Thanks Gord also for your helpful suggestions. I have tried manual but I tend to use mostly Speed setting. I set the speed & the camera picks the aperture. For moving subjects I have set it at 1000 or more. Tried some at 500, 250, and 125th. just to see if there is a noticable difference.

I tend to prefer aperture settings before speed. I want to determine how much area in focus I will need ie just one small bird (f/5.6), a large bird (f/6.5), a flock of birds (f/8-11). I then check to see if I have enough speed - a sitting bird (1/125 sec) compared to a moving bird (1/400) or a flying bird (1/500 sec+). If I don't have enough speed, I up the ISO - bright sun - 100-250, bright cloud - 320, dull - 400-800, very dull 1000-2500 etc. All of this I do in manual.

I do too and shoot with aperture priority set on my camera, which keeps the aperture set and everything else changes, I'll adjust the ISO to bring up the speed for my shutter or down for vise-versa. Another thing to remember is that most telephoto lenses have a sweet spot on the aperture setting near f8-9.5, this gives you the sharpest image. Also when using teles especially, low f-stops ie. f4 has the least depth of field and f22 gives you the most, the closer the bird is the shorter the depth of field is which can be great for blurring backgrounds, but hard to keep all of the bird in focus. Sorry probably a little to much to soak in Below is a link to a DOF chart play around with it. www.dofmaster.com/dofjs.html |
