Not all that convinced that there are practical advantages for a photographer as opposed to a happy snapper.
For example I just had a look at the web site and played with three pics.
The monarch butterfly,the waiting for prey and the practicing a swing.
In each case, to me, there is only one obvious "aesthetically correct" way to take the picture, so the advantage to re-focus on a different plane would be if I had the wrong part in focus in the first place.
Low res at 1.2mp, so no good for cropping (not possible at the moment anyway) and or printed 8'x10" or larger.
Not sure about this but it appears to have just one aperture, F2. That is very bright for an 8x zoom lens (if it is indeed F2 at 8x...) however you get that relatively shallow depth of field so , at the moment, not ideal for landscapes or just group shots.
(I had another look. Yes it is a constant F2)
Note that it is, for now , Mac but not Windows compatible.
Of course if you are happy with the "now is in focus, now it isn't bit" than go for it.
An example of a good alternative on what to have in focus is the surfer picture.
However in the sea lion one you can clearly see the low res and limits of the camera. Click on the background in that one.
(BTW, I had been following the development of this project )
