I went to the Singapore zoo and took these photos with my EM-5 II mainly and GX-7 taking the rest. Lens used was the much maligned P100-300. I think that it is a very good lens and if used keeping its limitations in mind, can reward you with very good images. I was very happy with the IQ and it was such a relief carrying the light wight kit in hot humid Singapore weather. The owl photo is at ISO 4000. Comments and critique welcome.
