Use the lens 45-150mm with derLumix DMC-GF. 3 I still have in addition the 14-42 X lens. The consideration was Lens 45-150mm or 45-175mm X Vario PZ. I still let me advise and Read some tests. The biggest difference was always the auto zoom when shooting. As for me personally it did not matter and at the price, the decision was not so difficult. Am absolutely thrilled of the Kombi. Hab ordered NEN UV filters. From handling her's is not a problem with the Lens because it is incredibly light in contrast to x lens. From the quality of the photos I'm thrilled. One can the objects at different distances each other play fantastically with the edge. Finally, I can like my predecessors this lens asolut recommend. For now 220 mam allowed as an ambitious amateur photographer no miracles expected but fo Eisteiger like me, it's top.
