P.S: using m.zuiko 12-50mm e depth of field is not tt satisfaction for me, tried oly 17mm f/2.8 but v expensive >_< , any idea/recommendation of len tt can produce a greater depth of field as compared to 12-50mm?
If this question is posted in the Oly section, you might get more advises. However additional piece of information you should give is... what is the budget... btw, I am using the Pana 25mm f1.4, it is a great lens in every aspect...
Oh... and be sure to tell people what is the focal length you are in.
