My impressions after a day or so.
The panorama function is great - a few 'jagged lines' on joins which are probably down to my tracking or a bit of parallax (not noticable to the casual viewer) , but haven't tried it using a tripod. I'm a bit of a stitch pano nut, so I don't think I'll be letting go of that, but it's a nice quickie feature.
Tried the Wi-Fi stuff today - loading files to pc via WiFi worked really well but was a tad draining on the battery, but the ability to connect iphone to camera directly using WiFi (and no router) to transfer photos (and subsequently text/upload to the web when out in the field) is a really useful feature.
Still trying to get the hang of the focus points. I've checked out the youtube video demo posted a few days back, but getting it to grab the right point is a bind for me at the mo - but it's my learning curve not the camera.
The noise levels in RAW are a great - but once I've tried it in a gig environment I'll be happier (I take photos of my wife's band).
Messing with the burst shooting - took a few pics of birds flying using this and they were mostly great (me again for the 'mostly' bit) - will be interesting to use this in a sporting environment (I take cycling photos) - hopefully when the National Time Trial happens the end of this month, I'll put this to good use.
CHOLLY - you're right - a massive improvement on the A350. Picture quality is excellent and the features are a bonus.
Oh - and the Lightroom exiftool hack worked nicely - I've kept the originals though and will replace the hacked arw files once Adobe get their act together.
