With Nex 7, my favorite are the 2 quoted "best" here:
Sony Zeiss E 24mm 1.8 and Sony E 50mm 1.8 OSS
I'm also almost happy with Sony E 10-18mm 4... (Not mine. I usually travel with my Voigtlander 12mm).
I like to use some good old Canon FD lenses too like Canon FD 85mm 1.2L, Canon FD 80-200 4L and also, for macro work, Canon FD 50mm 3.5 Macro.
Although more difficult to use (manual focus), they produce excellent results with Focus Peaking and Focus zoom help. The zoom optical quality is, for me, on a par with Canon EF 70-200 2.8L IS on a Canon body... without the size and weight! The 85mm provide exceptional OOF blur and Bokeh and also remains quite compact. And the macro, with or without bellow, does a very good job.
I also sometimes shoot birds and wildlife with Nex7 + Canon EF400mm 5.6 x1.4 (on a good tripod !). This combo has longer "reach" for almost static subjects than my Canon 1DX with the same lens...
