I also have the touit 32 so I would be thinking about the touit 12. Or, depending on your specific needs, something on the long end - say the Sony 90 2.8 or the Zeiss Batis 85 1.8.back in the day I used a leica with a 35mm, 50mm & 90mm lenses.
I realy enjoyed that kit. it seemed to do anything i needed
right now I have the NEX-7 wirh a zeiss touit 32mm and a sigma 60mm. I am looking to get the Sigma 19mm which to me would complete my three prime lens kit
so my question is what would be your three prime lens kit? - no zooms just three lenses of a fixed focal length
what would you pick to use on your APSc e-mount if you had to have a three prime lenses and nothing else?

Mr. Ed
The Zeiss 85 or the sony 70300 are next on my list.
