I was glad to see all the AF points are available with adapted EF lenses but I was a bit dismayed at the view finder blackout issue.

I was curious why they didn't demo the electronic shutter.

Also despite using an adapter + 500mm EF lens + 2X TC the birds they were trying to image were very small in the frame so I didn't feel like it was a really good demo.

The eye AF with perched birds did seem surprisingly good but that was not really my prime interest in this camera since my current kit does very well with BOAS.

The battery life seems awfully short too ... not up to driving the big lenses with IS and IBIS together perhaps?
