This is not intended to knock M43 and is not intended to start a DSLR vs M43 argument, but.... I am really interested in whether I can achieve the type of shallow DoF/subject isolation/3d effect automative photos that I like without adding a fake PS background blur. A quick google images example (not sure what camera/lens this was with): Subscribe to see EXIF info for this image (if available) I own 20mm and 14mm Panasonic primes for m43 and have access to (through work) a D800 with 50mm f1.8 and 85mm 1.4 and a 5D2 with the 24-105 f4 lens so know what FF can do. I assume I'd need to buy a lens as not really succeeded with the 14 or 20 primes - can a Pan 42.5mm or Oly 75mm achieve the same results? Or even the 35-100 2.8 Pan?
