The current equivalent F-mount lenses are selling for ~$US175 plus tax for the 50mm f/1.8G black version and ~$US455 plus tax for the FX 35mm f/1.8G.
It will be interesting to see just how long it takes for European lens price reductions to filter down to us in the southern hemisphere. Often we can negotiate better deals on the day, especially if one buys a body and lens kit or if one waits for a "Black Friday" sale.
