Thanks for sharing that serhan. I really do like the metal finish of the Sony SEL lenses. The build quality is so good, smooth and solid... with no plastic slap that so many AF lenses have these days (which is a major turn-off for me). This was one of the reasons why I bought my NEX-5N even before I realized how good the sensor is.
From what I've read, it seems that the Photozone writer forgot that the SEL lenses have a multiplication factor of x1.5 to the film SLR equivalent. The 50mm 1.8 is not a standard lens... it is in fact a medium telephoto suitable for portraiture, and with f1.8 it should be ideal of low light and beautiful bokeh.
The 30mm macro is not a wide-angle on the NEX which the writer was puzzled about. It is in fact a 45mm equivalent which is the realm of most macro lenses.
