Focus setup on EM-1

[cherryw]

Hi All,
I have been having a spot of trouble with focus on the EM1. Yesterday whist trying to get shots of a Lyrebird most of the shots were out of focus. The setup was 50-200 ED (non SWD) with 1.4X and the 4/3 to M4/3 converter and as such not much light getting through to the sensor. ISO 1600 and so lots of noise. When trying to focus it was hunting for focus and was shooting f4 at 1/10. If I push the iso up anymore the noise is just too great to be of any use. I need help in trying to find out if I need to change focus from centre spot to a broader pattern. I was also thinking that maybe using the FL50r to assist to see if this helps but as these birds are too far away (10m) will it work.

Thanks in advance.
