These were two things I had wanted on the E-M5 - so glad they added them. Smaller point focus desired for shallow DoF portraits and for much of my landscape shooting I end up over exposing ISO200 already and will be glad to have the extended ISO100 to do it for me (or at least start out closer).

Hi Ken,

Long time no see. Glad to see you around.

But as to the ISO 100: Why would you even want to use that as a RAW shooter? Surely, all the ISO 100 setting does is to alter the metering and the tone curve of the OOC jpegs. The clipping point in RAW stays unchanged and if you go by the live-view "blinkies" when setting exposure, as I do, there is no difference between ISO 100 and ISO 200.

If shooting mid/low contrast scenes/subjects (using ETTR), won't ISO 100 then give a less 'washed out' live-view image in the EVF and more natural looking JPEGs?

Yes, it would, and that may possibly be an advantage with regard to in-camera review even for a RAW shooter at times. On the other hand, high-contrast scenes will now come out looking more "underexposed" than they would at ISO 200 so it is a mixed blessing (unless you take the trouble to switch between 100 and 200 depending on the contrast of the scene).

Another little problem with the "fake" ISO 100 setting is that it makes things inconsistent across ISOs. If I ETTR at ISO 400 (which makes sense on the E-M5 when you can't saturate the sensor at ISO 100/200), things will look different in terms of brightness than if I ETTR the same scene at ISO 100. Staying with the regular ISOs makes things consistent in that regard.

Yes, a bit confusing if the tone curve and amount of headroom vary at different ISOs. And btw, maybe you could check whether ISO 100 actually is a 'fake' ISO. Would be very surprising if it isn't, but don't think that anybody has checked it yet.

Small focus box without having to change to zoom-frame AF: Well, I am just as happy to have that as you are. This was at the very top of my list of things to be fixed.

There is of course a long list of other things I want to - but these were near the top of the list and there will always be another feature for me to be annoyed by (AEB Fn access - argh!).

As to focus peaking I may be remembering wrong but I thought at some point in the past some one from Olympus had said in an interview that appropriate processing and hardware resources were needed to effectively implement focus peaking and so it might not be practical to do on older models. It was a long time ago and I might be confusing this with a Panasonic interview on the G/GH series cameras instead.

Personally I've tried focus peaking on a few cameras and didn't find it useful, but since I didn't own those cameras and couldn't use it for long enough it is quite possible I just was familiar enough with the implementation to use it effectively.
