Old City Hall -- NEX-5 & Kiron 28mm f2.0
Kiron made a few nice fast wide angles. The two I have tried and liked are 24mm f2, and 28mm f2. Both of them are very good lenses. This picture was taken with a Canon FD mount 28mm f2. Very good performance for an old lens. There are Vivitar twins of this lens (and the 24mm f2) out there. The FD/MD/KR versions of this lens is still dirt cheap. Perfect on the NEX or Micro 4/3 cameras.
