Characteristics I'm looking for are as follows: --- Generally inexpensive and costs under $550. --- I also own a Nex 6 with kit lens (18-55 x 1.5) and tend to shoot at 18mm which translates to 27mm with the crop factor. --- Adequate for street photography, architecture, and general all purpose. --- Impressive optically. (Good sharpness, produces natural colors, etc.) --- Produces creamy bokeh. Feel free to list zooms and primes. Note though I'm somewhat partial to primes since I do want some semblance of bokeh. This will be coupled with my GX7. I only own one lens so far and that's the Olympus 25/1.8. Thanks in advance. EDIT: Updated post to mention preferred focal length.
