And on the A350 you can always just switch to live view, viewfinder
blind comes over and you get 1200-zone evaluative metering read from the
focus screen - with alarming accuracy.

Can you elaborate on that? I don't quite understand.
Do you mean the metering in liveview is different than with the OVF?

And how is it alarming?


Yes, in evaulative (matrix) mode only. In centre weighted and spot, you
get the normal system. In matrix mode, the CCD video sensor does the
metering instead, and of course you never get overexposure (it's like a
bridge camera metering in that respect) and there is therefore no need for
the camera to underexpose slightly, which the A350 tends to do with
regular metering just to make best use of dynamic range (9.2 stops at ISO
100 according to Anders Uschold in the BJP yesterday).

With Live View Matrix metering, you get 1200 colour sensitive points and
the live view image perfectly matches the final output in terms of the
live histogram, as well. with LV metering there really is no need ever to
think about bracketing, it's like using the KM A2 (which I still use
occasionally).

David

Thanks for clearing that up. Now, of course: how does it differ from say,
Canon and Nikon LV? I assume they don't have that CCD video sensor, because
the mirror is locked up, right?
