I'm looking to upgrade my kit for the OMD. I have the PL 25, and the 12-50. I need a good landscape/moderate wide angle lens. I've thought about the 7-14 but its so expensive for the limited use I'd get out of it. I think I'm between the 12mm and the 12-35. The different strengths and weaknesses in specs are fairly obvious. My low light needs are taken care of with the PL 25 so the f stop advantage of the 12 is no huge concern. And it would be nice to have the flexibility of the 12-35 without changing lenses while hiking, dirt biking ect... IQ wise, is one of these lenses the clear winner? And a subjective question, is the 12-35 really worth the extra $$?
