The process to create bokeh is the same no matter what sensor you've got

I read something funny on the net today, a writer espousing that mirrorless small sensor cameras (e.g. Micro four thirds) can't do bokeh. He was saying it wasn't physically possible. I think that maybe he doesn't understand physics of light quite as well as he thinks he does. This image is taken with the Olympus EM-1 Mk II which is a Micro Four Thirds camera and it seems to have plenty of bokeh to me.

The secret to making bokeh generally has three elements
- a forground subject (in this case the wire)
- a background which is either backlit like the leaves on this plant - or small bright sources of light such as fairy lights or a christmas tree
- a wide open lens in this case f/2.8

Now interestingly his idea was based on a physical property that is true, on my sensor f/2.8 is the same as f/5.6 on a full frame camera for depth of field but not for light. For light f/2.8 is exactly that, f/2.8.
