If I were you before dropping big bucks for lens I would rent or borrow them if possible first. The NEX cameras balance is not like a DSLR and some lens I tried I found a bit odd if you are panning and shooting. I do have the Tamron 18-200 on an A65 and it works well in especially if you are planning on only 1 lens for travel etc.
I don't have either but I do have a Vivitar 28-210mm. Vivitar 28-210mm f3.5-5.6 zoom lens for Pentax PK-A mount > Pentax PK Manual > Used Pentax Lenses > Used Pentax > Used Cameras, Lenses, Flash Units and Accessories. > Used Cameras, Lenses and other Photo Equipment & Services from RS Photographic of N I like it, but you better have a better have a steady hand and descent light. Two shots showing the range. (Not great pictures) Near {} Far {} I am currently saving for the SEL18-200mm.
