Sony NEX-5N, Sony 50mm f/1.8 @ 1/1000
f/4 ISO 200
100% crop with no sharpening.
Image quality is great,
just as you'd expect for a f/1.8 lens stopped down two stops. Focusing
is decently fast, for contrast based AF. Certainly not even as good as
a kit lens with phase detect AF. As far as build, the Sony 50mm f/1.8
OSS feels good. The outer body is metal, but the lens is still light.
Manual focusing is typical for the series with a "fly by the wire"
connection that I'm not a big fan of. It's better than most Nikkor AF-D
lenses but below a good AF-S for manual focusing. This lens is larger
than I would have expected,
slightly slimmer but longer than the 18-55mm kit lens. Shooting a
portrait I tried to use continuous AF, but found it has hunting for
focus too much and ended up shooting manual to nail focus on the eyes.
Ironic because it seems like AF would be a big advantage that this lens
has over third party lenses adapted to the NEX system, but the AF just
isn't up to the task in dynamic situations.
