Anyone using a Panasonic Leica 25mm f/1.4 (the new m4/3 one) with an Olympus Pen body? Mine arrived this morning and the aperture blades are constantly moving and "clicking" adjusting to the light, when the live view or EVF are on. Only way to stop it is to turn the AE lock on. I've used it on an E-PL1 and E-P3 and its the same on both. Everything is working fine apart from this, the pictures are perfectly exposed and very sharp. If you are using this combination with no problems then I know I have a faulty one.
