Well, the long pro zoom has gone.
Looking at my lens options now (more on that later), I took the 75-300 out for a spin in the garden this morning.
There is that niceness the cheap zoom has. Great colour, more than adequate sharpness, surprising bokeh and good accuracy.
Something I still under estimate with M43 and long lenses is the lack of depth of field at closer focussing distances. The image below is sharp in the centre of the flower, but the stamen is a little soft! Even as slow as it is, this lens does not guarantee enough depth of field always.
