I'm currently having an internal debate with myself regarding the best selection of lenses to acquire so that my M43 will give me a full coverage of focal lengths. So far I have P14, P20 primes and P14-42. I also then have 2 lenses for my D5100 - N18-55 and N35 prime (btw - I am probably selling DSLR and moving exclusively to m43 - again!). The trouble is with having 2 different systems and lenses that are very close in the focal lengths that they cover, is that they overlap and I am lacking in ultra wide and telephoto. What is your perfect lens line up? Is the 45-200 more popular/better IQ than the 100-300 for example? How about the 14-140mm? What about the 7-14 vs the 9-18? For info I shoot anything and everything so don't have a particularly speciality and want to cover as much focal length as possible.
