With my E-PL1 coming, I look into my photos and I noticed some of them were taken between 1/2000 and 1/4000. In order to gain shallow depth of field on m43, wide aperture is needed. How does this bug you with everyday use of E-PL1? I'm planning to get a ND8 for 20mm 1.7 but I couldn't get every filters for every lens I have. Nor carry them all every day. It might not be a problem at all, since I haven't really tried the camera in real use yet. any opinion?
