Hi All, Been in a bit of a delima lately with replacing my 14-45 with a 14-140. I'm happy with the 14-45, however i do wish to have a bit more range at times, and i do want a lens that does it all. I've read reviews that the 14-140 is a bit slow in AF, and not that sharp overall, however i do believe that is debatable. I guess the question is, is it worthwhile to have both 14-45 & 45-200 and change lens to suit your subject? or have a heavier 14-140 to reduce the lens collection? Am i wrong to assume the 14-45 & 45-200 can replace the 14-140? Thank you all for any comments.
