First I am using it on the OMD E-M5 and the lens is one of only 2 options in the native micro four thirds mount, so if you are shooting a Panasonic body buy the Panasonic with OIS. If using the Olympus body the decision is harder a few stops of light of the Panasonic vs size and extra focal range of...

There aren't a lot of choices for a 300mm lens in the M4/3 world. I was a bit hesitant to purchase this lens because reviews said it was soft at 300mm. It is compared to the excellent sharpness it exhibits at shorter focal lengths.

I like how I can now get closeups of birds and animals that I was not able to get with the 40-150mm lens. This is much bulkier, but it is worth it. The pictures are sharp as the OMD stabilization system makes a big difference.
