OM-1 Bird AI consensus...?


I've been reading that Bird AI with C-AF+TR works better than with Bird AI and C-AF.

I really don't know if that's true or not.

(some of my preliminary settings)

re: Bird AI subject detection

For perched birds (regular A mode with auto ISO and Auto ISO min shutter speed settings).
--------------------------------------------------------------------edit-----------------------------------------------------------------------------------------
I set small AF target and use Bird AI C-AF+TR, 25fps SH2
that part is wrong.
with C-AF+TR I can not pinpoint anything using the small or single AF target group.
I changed the AF mode to C-AF with single AF target for perched birds
I can put the small focus point on a small bird and then let the Bird AI C-AF+TR do the rest.
that does not work...the AF can/and does go anywhere it wants in the frame and not does not adhere the AF target mode (small/single). I suppose one could use Center Priority with C-AF+TR but I just switched it to C-AF.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------
I have C3 Bird AI C-AF+TR, set to slow fps 20 fps and low shutter 1/125 (low ISO) for really static birds and/or in much lower light.

For BIF I have two settings (both based off A mode);
for large/slower birds C1- large AF-Target group with 25 fps SH2 and C-AF Bird AI
for faster birds C2- ALL AF Target group, 50 fps SH2 and again C-AF Bird AI.

I might consolidate these two settings...we'll see.

I haven't used AF limiter nor have I played with C-AF sensitivity.

The metering on the OM-1 is a lot different/better(smarter?) than the EM1mkII and the EM1X.
I set the two BIF C modes with a default +0.7 EV compensation because I am usually pointing the camera up at the sky for BIF and with the other two cameras this usually meant substantial underexposure. With the OM-1 I do not need the + 0.7 exposure compensation.

+1 for an OM-1X.
I used my A9 ungripped with the 200-600 and would have added a grip had I kept it.
I am using the OM-1 ungripped with the 4/300 (and TCs) but I do prefer the ergos of the EM1X to the OM-1.
hoping my 150-400 is here by friday so we'll see how it feels with the OM-1. I may opt for the HLD-10.
