When is an image perfectly focussed?
I have a new toy – a lens. I took it to Dunedin when we visited Nancy. I had a few minutes and sat down in her warm, sunny lounge to take it through its paces. When I pointed it at the little bright lights reflecting off her 70s-décor, brown, patterned glass conservatory walls, the lens was set to manual focus, and was focussed elsewhere, and I smiled. And I played. And this is the result. And it’s perfectly focussed.
