Currently I have 12-50 zoom (using it primarily as 12mm), 17mm 1.8 and 45mm 1.8. The first lens I bought with my OM-D was 17mm 1.8. I had some experience with 35mm lens on my friend's Nikon D800 and really enjoyed it over 50mm. However my first dissapointment with 17mm 1.8 was very wide DOF. The images of people mostly looked flat compared to FF version even wide open and you could get only some subject isolation if you shot half body portrait. Since I mostly shoot portraits and landscapes it is sad that I cannot use 17mm for portraiture. Now as 25mm 1.8 has been announced I started thinking about selling my 17mm 1.8 in order to fund 25mm 1.8. It seems that 12-50 zoom can do anything 17mm does past f4 (landscape speaking). However I am not sure whether there will be much difference between the 17 and 25 in terms of mu-43 sensor size. What would you recommend? Perhaps there is someone who has experience using 17mm and 25mm (Panaleica). I don't expect Oly 25 to be the same as 50mm on FF body, but I am looking for a good amount of bokeh (preferably some subject isolation full body). And am I right that 12-50 zoom can actually substitute 17mm 1.8 for landscapes and the stree? Thank you.
