the v1 and the cx 70-300 is a combination I would love to try
how is the Af ? if it is as quick as with the other CX lenses this should be very nice to shoot birds , surfers, any kind of far away action , provided there is good light
one only have to learn to work around the long delays of the camera waking up from sleep or switching the image to the viewfinder
WB with the V1 is always a bit off
