I've tryed my hand at shooting birds. I don't have experience at this one and, after harassing the crows that live happily in front of my building, I've reached the conclusion that there are too many things that I don't know on the subject.
I've used a Tamron 28-300 and and the EF 100/2.8 macro, none has IS.
It was late afternoon and I've chosen ISO 400, TV set at 1/500 and aperture came out at 6.3 for the 28-300 and 2.8 for the 100 mm( widest for each lens).
RAW, AF-servo, single point focusing, continuous shooting drive.
Appart from my personal record of about 300 shots in about an hour, the rezult is lousy.
I know that the lenses I use are not the best ones on the subject( the 28-300 is an old one, soft is it's middle name, and slow focusing, and the EF100 is, well, 100). But doing the right thing I should have had at least one decent shot.
Annoyng noise, the highest I've managed with this camera, out of focus, and obviously 1/500 is not enough to catch a bird in flight ( but I may be wrong, of course).
One other thing is the difficulty to switch swiftly from binocular view( i.e. my eyes) to monocular one -the camera- and catch the bird in flight. But this may get better with practice.
I know I'm doiong everything wrong, I like to learn from experience, but I'd like also to have some pointers in the right direction.
Thanks
Those, appart from some cropping, have no PP
1- 300mm
2- 100mm
