Nex-5R vs Nex-5n AF test on youtube now
I found a nex-5r af test on youtube
The light condition is pretty poor, judged by brightness and color cast in the videos.
OSPD should have reduced effect or can't active at all at low light.
5r indeed faster than 5n, although not by large margain, IMO, during the test, the 5n AF is fast enough.
There is still back-and-forth AF attempt in 5r, however, when AF direction is determined, the AF is very fast, looks like the PDAF is kicked in.
