before I go and...

...spend time experimenting...
When a camera is in burst mode, does it focus at each shot or just the first/
Is the behaviour different if in s-af rather than c-af?

Re: before I go and...

As far as I am aware having used burst and C_AF at an airshow, the focus picks up an object and follows it so it remains in focus. It also stays with it even if another object passes by. Fine for objects that are coming closer or moving away. I wouldn't set the 'sweep' stabilisation as that only works well L to R or vice versa. I.e. racing cars.
With S-AF, focus is set when you depress the shutter and it doesn't change from that point until the shutter button is relieved of pressure. Fine for objects that are remaining the same distance from the camera.
This is my experience on E-500, E-3, E-5.
My overall problem is pressing the shutter too soon and running out of buffer on burst.

Yes, tried it in s-AF and it picks focus on the first frame.
I note that some other Cameras have a slower burst with focus on each frame.
Must try c-AF with face detect to see how that performs.
I am wanting to use it for gig photography

The camera will only focus on the first frame in H mode, but it will attempt to focus on every frame in L mode. Obviously you need to set C-AF mode at the same time.

Re: before I go and...

Thank you Ian
as the frame rate can be set for H and L burst...
Is there an upper frame rate for the L burst at which it will stop attempting focus between frames?

I don't have an E-PM2 but as I believe there is a variation between different cameras in the way these things work I checked the PDF manual online.

The information is all in the camera manual p.36.
The frame rate is not adjustable it is "about 3.5 fps" in L and "about 8 fps" in H.

Additionally, p,78 tells you how to modify the Automatic Focus Lock (AFL) and Automatic Exposure Lock (AEL) functionality by assigning them to a Function button.

I'm not sure it is only the camera that "decides" to stop "attempting" to focus. The critical factor is how fast the lens aperture mechanism can react as it is, I believe reset for each frame. With my OMD EM-5 the Panasonic 100-300mm lens would not work at H burst (9fps) but the newer design Olympus 75-300mm which I now have will for this reason.

Regards.

L fps...1,2,3,3.5
I suppose it is time for more experimentation...

Re: before I go and...

Just used the 45mm f1.8 and set L burst to 3.5fps with C-AF and walked back and forth to the target and it focusses...usually
moving more quickly side to side the hit rate is lower...
Ah well a couple of weeks to the local blues festival to try in anger

Ah yes forgot the Cogs C menu.

Olympus manuals are not easy to follow are they.

Good luck with your experiments/practice. Hope you get it cracked for the gig.
