Recently bought a unknown brand lens from taobao for my Olympus Pen F. Funny name if you pronounce it in Hokkien :bsmilie: It's a m4/3 mount so no need adapter. Light and balance when mounted on my Pen F. I love the bokeh though F1.1 has a really shallow dof. However I realised that peaking for manual focus does not work. Compared to using a manual lens on Fujifilm X1 the peak focus will still works. Below are some sample image except the last one taken with 25mm.
