Those clever engineers - phase detection AF in a compact

Props to Fuji for thinking up a way to do contrast detect AF right off the sensor:

I thought about getting this camera though the sensor is very small. Maybe someone will have a review out soon.

And right around the corner is the new Sony - with a semi translucent mirror to allow full time phase detect AF. Due to the sensor/SLR (SLT!) sizing it is of much more interest for stock photographers I would think...



SONY SLT-A55



Kind of reminds me of the old Canon film camera (Canon Pellix) with the half silvered mirror - it gave you a continuous viewfinder with no mirror flip, but at the expense of a third-stop of light.



I wonder if the Sony will have the same issue the Canon did - the mirror degrades over time and affects the image, rather than being smartly moved out of the light path during exposure.
