Really? 1/60 sec. I would be so much more productive if I could pull that off.
I'm uncomfortable shooting below 1/800 sec without "IS". At slower SS I must
burst a few frames in hopes that at least one will be sharp. Also, since I have
very little telephoto reach the AF does not always find the target and will focus
on a leaf, or branch instead of the bird. With more power the bird would justify
a definitive focus lock by virtue of its pixel capture. Setting for center-weighted
AF does not eliminate the problem but it helps. In rare situations when my camera
is well-braced and timing is not an issue I can switch to live view and hit the digital
magnification of 5x and then focus more critically, although that method can take
the better part of the morning. For stationary birds like herons or ducks it can work
well. For passerines ... not so much Some day I may have an IS lens but by that time
the sun may go Nova. I figure my old Canon t4i will likely bite the dust soon. A camera's
shutter has only so many excursions in its life and I've been using it since 2013 so
who knows what will happen.
