As a newcomer to the m43 world with a GH1 and Panasonic 14-140mm lens, I am considering going the whole hog and selling all my Nikon DX gear in favour of an E-M5. In the UK, EM-5s bought before the end of the year from a suitable dealer can claim a 45mm f1.8 free of charge. I currently do my GH1 raw conversions in DxO, mainly for the excellent lens corrections and noise reduction capabilities. However, the EM-5 and 14-140 is not a supported combination. I'm not a huge fan of either Lightroom or Camera Raw but will use them if I have to. My first question is, therefore, do others use the 14-140 with the EM-5 and if so, what raw converter do you use to overcome the distortion and CA issues? Secondly, if the 14-140mm can be used successfully with the EM-5, I'd be looking to supplement the 'free' 45mm with some additional fast primes to get some more DoF contol as well as avoiding tripod use as much as possible. The 14mm Panasonic, 19mm & 30mm Sigmas and the 20mm Panasonics spring to mind - with up to three probably being chosen from this group. DxO supports all of these with the EM-5. My budget probably precludes the 12mm & 75mm offerings. Suggestions and recommendations most welcome. I should add that I have broad interests with architecture, street & documentary, landscape and event photography well up there.
