Also the bigger grip on the E-M1 helps handling that rather long and heavy lens combination.

If you want long focal length with less weight and faster / more accurate focussing on the E-M5 II, and mainly use it outdoors in good light, then the 75-300 is a good lens, and comparatively tiny and light, though not as superlative as the 50-200. There's also a Panasonic 100-300 but I have no experience of it.

Thank you very much, I was contemplating using it mainly for considered compositions.
The reason I didn't consider the 75-300 was because of reports that when at its maximum extension the sharpness tended to change to a more soft result

No reason S-AF+M would be different than the other modes.

Re: Olympus lens + MMF1 + EC-14

The reason I mentioned S-AF + M is that I sometimes use the manual with focus peaking to make fine adjustments.

Re: Olympus lens + MMF1 + EC-14

Just one small point to add - the MMF-1 converter won't have any effect at all on image quality. It is just a tube with no glass elements in it - a 4/3 mount on the lens end, a micro-4/3 mount on the body end, electrical contacts from one to the other, and the correct length for the difference in registration distance. Same with all the other 4/3 to micro 4/3 adapters.

Many thanks John, I had difficulty finding An MMF-1 they must be in short supply.

MMF-3 is a better bet anyway as it includes weathersealing.

Re: Olympus lens + MMF1 + EC-14

I still have the 50-200 Mk I which I rarely use now, as the 75-300 Mk II is pretty good, and a lot lighter and smaller. I tend to back it off 300 to 285ish max,and stop it down a notch where possible. Some recent shots starting here on Flickr: https://www.flickr.com/photos/bruce-clarke/24345955747/
