All the images were taken on 'full auto'. EXIF of original file says ISO 100, 1/400th second F6.2
I struggle to use the screen to focus (I am used to a DSLR) but my wife, who will be using this camera has no such issues.
Biggest advantage is the whole thing weighs very little (compared to my DSLR, Telephoto lens etc.) and I am sure with practice we will achieve some quite reasonable images. Focus is quick and pretty accurate. Main negatives, for me, are small (read useless) viewfinder and the write time, even for jpeg files. We have not yet tried to shoot in RAW. No point in having 10 fps if you can't see what you are shooting!
If you take it for what it is, it is a useful piece of kit. It it not a DSLR and cannot produce DSLR quality images (not at the 'long end' in my hands anyway). We have not yet tried to take non birding images so it may perform better at shorter focal lengths.
We are looking forward to honing our skills to produce better results and have no regrets over the purchase. We bought it last Friday from Park Cameras in Burgess Hill. The price was £399, or around half of what it would cost for a secondhand 400mm prime lens....with nearly twice the reach.
Hope this helps.
