Obviously the laptop is not far from the mouse and I was at least a meter away as that is the minimum focusing distance of the lens. Just used an E-P2 for this (so please pardon if the photo is a bit noisy) before I got poisoned by the E-P5

I know that everyone has different standards for bokeh but I just want to demonstrate how much can the 75mm blur the background. I was in a small room and I was pushing my back in a corner to try to make as much space as possible to include the laptop as well when taking the shot. The black blur to the left of the laptop is the back of an office chair. We all know what is the size of the mouse and laptop so I hope it can give you an idea on how far away you need to be from the subject when using the 75mm lens.
