I'm very disappointed with the V2 camera. I have two one bought last week when i believed that the original focus issue had been fixed in manufacturing. Don't think that is correct now.
Taking two pictures side by side out of my back window one with the old camera and one with the new, both at 1280x720. The old camera is MUCH better. Crisp clear and focused. The new camera gives a muddy picture more or less focused in the middle but very soft towards the edges.
Both pictures taken with raspistill with only the width & height specified.

Does anyone still have stock of the old camera?
