I would like to see some raised "feel" feature on the AF button, either a raised ctr or rough finish so it can be detected by feel in a hurry, And I am not so sure about the two sd card slots, there needs to be a clearer, coloured or larger display to show which one is in use or full. I have already had the situation where I changed over a card and then formatted the one in use, not the new one inserted....yes, my fault I acknowledge
that and it has certainly caused me to slow down when changeing cards (I can shoot several thousand shots in a weekend using 4 & 8gb cards, so as we can keep the processing rolling))....but something that could do with some more thought to get the best out of it.
AF still needs work, it is definatley better but still needs an element of technique to get the best out of it.
