Just returned from a trip to Iceland & Norway and a little worried about how many keepers I have got from flying birds. Not many have the head sharp in focus. Is there something I am doing wrong? My exposure is 1/3200–1/4000 so that shouldn't be a problem. Using C-AF, Bird detection, AF Area - Large or All, SH2. Can't use back button focus due to my disability. I went from having 90% head sharp BIF with my Sony A9 III to around 20% on my OM1-MK2. I love this combo for everything else, but BIF is becoming a problem.
as a fellow OM1II and 150-400 user I will be following this thread.
I've been using the 150-400 for nearly 3 years now and I have never achieved even close to a 'great' BIF keeper rate with it.
I usually get something meeting my requirements from most BIF burst sequences though so...good enough.
I shoot 25 fps SH2 so as not to not fill my cards in an instant. It's been said that 'we' should use 50 fps for BIF. I have no argument for/against 50 fps as I've not 'tested' 50 fps for myself.
maybe more salt on the wound...
if you can and haven't already...try the 4/300 for BIF.
when I first received the OM-1 I was using the 4/300 for birds/BIF (with an EM1X).
*I used an A9 and FE200-600 in between the EM1X and the OM-1.
with the arrival of the OM-1 I immediately and very easily achieved a very shockingly high (coming from the EM1X) BIF keeper rate which is what gave me the confidence to buy a 150-400. * I upgraded to the OM-1II when it was released. I have never consistently had a BIF keeper rate with the 150-400 that I achieved with the 4/300 with either the OM1 or II.
