Although I love the quality of my 75 and 12-40, they take up a lot of space in my bag, and they're (relatively) heavy. I moved to m43 from Nikon to free myself from big+heavy. So I'm seriously thinking about selling them. For portraits (which is mostly what I've been using the 75 for), I have the Olympus 45. For wide - which I must keep - I have the 9-18. The 12 isn't wide enough for me, and I can't live with fisheyes. Anyone else with the same dilemma - or suggestions for me?
