Please suggest a lens!
I am heading for a week length vacation to Budapest. I have packed the K5 and the 16-45 f4 ad main lens. I have also taken the Sigma 8-16 as i thing it will get used for architectures. As I travel alone I do not need a versatile (big) tele zoom. For in case I have thought to take either the Takumar 105mm f2.8 or Takumar 135mm f3.5. I am thinking about the special details which may demands extra reach. I love the quality of the 105 but I am not so sure about the 135. I only know it gives me extra reach. If some of you have been in the same situation you may kindly share your thoughts with me.
