I'm looking for a faster, sharper native lens for my a5000. I have the 1650 and 55210 kit zooms. I like the IQ of the 55210 better, but I shoot a lot of landscapes. The 1650 is decent at 25-35mm, but it would be nice to have something with better color and sharpness. I'm currently considering the SEL50 1.8 or Sigma 30 2.8. Leaning toward the Sigma. The Sony is probably too narrow, but the IQ, 1.8, and OSS make it tempting. Before I decide, I thought I'd ask for feedback here. Also, are there any other good alternatives in my price range (about $250)? I know lenses can perform differently on different cameras, so it may be worth mentioning I'm planning to pick up an a6000 in a few months.
