I use autofocus most of the time when walking around. I use a single focal point and try to focus on the eye. The blurred background is a result of the long lens (I shot most of those at 500m and wide open (f5.6). (I use manual focus most of the time on landscapes)
Thank you for the compliment. I am totally new to wildlife and bird photography, so, I will be shooting on my daily walks until I can do it without thinking.
Those shots are all a little grainy, I shot at ISO 4000 to 6000 because I was hand-holding that heavy long lense and wanted to keep my shutter speed up as high as possible (over 1/1000 sec) to avoid motion blur. I need to get that ISO down to 1200 or so to reduce the grain/noise which will make the images sharper.
But, I will learn - it's fun and at this time of the year there are a lot of birds that want their photo taken :).
I will post some more tomorrow with a lighter faster lens.

The laws of photo have not changed. They often are no longer taught. For a 35mm camera a hand held speed is the focal length of the lens thus 500 mm 1/500th of a sec.
If, the shutter is opened twice as long 1/500th vs 1/1000 you can lower the sensitivity
as in 6000 to 3000. Old school perhaps, high speed was tri x asa 400 that you could push to 800. Kodachrome was asa 25. |
