Hi. I was wondering if anyone had experience with both lenses? I am looking for a wildlife lens and was debating between the two lenses. A Used 150 f2 with adapters goes for about the same as the 40-150 pro at this time. The 150 f2 is a stop wider and has the ability to add on the ec-20 to become a 300 f4 which would be great if the 300 f4 m4/3 lens doesn't come out before in go on safari the first week of February 2016. The 40-150 pro would have more flexibility as a zoom lens and focus faster. Aside from that how do they compare IQ wise. I would guess the 150 F2 would have better bokeh. Both are suppose to be very sharp but i read a lot of 150 f2 owners feel like it has that extra something in the IQ department like the 75 1.8 does. I only have a em5 II currently but will be getting a EM1 used for either lens. Thanks for any input!
