>>3359151it's a very populat brand. and yeah thats the famous 50mm that they make but make your own research. i recommend Kai man wong. he's a great presenter for photography gear. also Technology Mafia makes A6000 series lens reviews only and i would say is very reputable.
this is what i have that mounts besides the standard lens. that i have a leica adapter and a canon adapter. obviously i have lenses for such cameras but it shows how vast you can take your camera.
if you need a Auto focus lens go for the newer sigma 30mm or 60mm lenses they're cheaper than sony lens and are praised for their price to performance.
**maybe the 19mm would be best for your application. since you are going for more architecture**
