I'm thinking of swapping out from a Canon 550d with Sigma 30mm f/1.4 to an Olympus OM-D EM-5 with Panasonic/Leica 25mm f/1.4. Now I read/get told all the time that the sensor size affects Shallow DOF/Bokeh, but I think this is mistaken. From what I can gather is it's just the difference between a 50mm lens and 25mm lens to get the effective FOV and nothing to do with the sensor size (although you are having to go to 25mm instead of 50mm FF BECAUSE of the sensor, so....). Anyway, 5mm difference doesn't seem like a lot to me, so I'm hoping I'm not going to loose much shallow depth of field. Has anyone got any good examples and can sooth my apprehension on this matter. I'll probably end up with the Voigtlander 17.5 at some point, but only the 25mm 1.4 to start with. Thanks for any advice Christian P.s.
