What I found with DS 2.0 Firmware

I was trying to see how the focus, exposure etc was effected by firmware upgrade. What I found.

1. focus was faster in low light. BUT focus was not necessarily where I thought it was. (Camera focused on frame)
2. Auto ISO worked as expected. (200-800)
3. Exposure was slightly under exposed (BUT better than with 1.0.2)
Photo below was taken hand-held. Source of light candle only.
EXIF f/4.5, 1/6 second, ISO 800, 43mm
Critique is wanted and expected. Re-sized for web.

Joel,

Stunning to be sure!

How the heck did you hand hold at 1/6sec? I can't get that steady at 1/30th!

Sat in a chair with my two elbows against my chest, then held my breath. The same way you use a Rifle (Taking in a breath then letting it out before pulling trigger)

P.S. I also used the mirror lockup in 2second timed release.

It looks like the frame is in the centre of the image, not the candle.
Was it with centre-only focus point?

I set it up to have 4 fields of focus.
1. The Chain
2. The Candle Stick
3. The Pocket Watch
4. The picture frame.
I was testing DOF and focus points. By looking at the picture you can tell the location of final focus. I took four separate low light shots to check focus.
