I find the manual focusing to be perfectly acceptable. However, it won't change focus while recording.

The adapter feels ever so slightly loose on my GH5.

Dismounting the lens can be somewhat difficult, any advice to easily and safely remove it?
Sounds like there's something wrong somewhere — manual focus should work fine when recording on the GH5. It does on my GH5S, and I'm not aware of there being any published difference in that regard between those two bodies.

Which adapter did you end up getting?

A still I grabbed from my first video using this lens. 120fps / 180 degree shutter / f2.

I recommend attaching the adapter to the lens and then instead of holding the camera and attaching the lens, do the opposite, i.e. hold the lens and attach the camera to it. To remove, simply reverse the procedure.

You can't really tell from this compressed image, but the 150/2 captured a lot of feather detail on this duck. (ISO 200, F2.8, 1/1250)

This Buff-Banded Rail caught me by surprise. If I had more time I would have stopped down to get more DoF. (ISO 200, F2.5, 1/80)

I got the Olympus MMF-3. I've read that being slightly loose is a common problem with this adapter. Perhaps that slight looseness is enough to cause an electronic miscommunication.

And to clarify, this issue happens while recording in VFR. For some lenses the GH5 disables IS while recording in VFR, so maybe there's a similar bug that disables manual focus for some lenses.

Thanks!
Attaching the two doesn't worry me at all. I've found that softly pressing the camera against my body helps a lot when disconnecting.

I've found that such a bug exists (at least on the 150 f2 / MMF-3 / GH5 combo). I disabled VFR and was able to manually focus while recording. I then turned on VFR. Manual focusing worked while not recording, but, as soon as I pressed record, it stopped working. I stopped recording and was able to manually focus again.

EDIT: I've created a new thread for this issue, so I deleted all subsequent posts relating to this issue in this thread.

GH5 no manual focus during VFR with Oly 150 f2/MMF-3.

It's not a bug, that's how VFR works. You can't adjust the focus once recording (just like how you don't capture any audio while recording in VFR).

I don't do a lot with CAF, so I played around with it today using my 7-month old lab as a model. Pretty much nailed focus on her cute little head with this one:

...not quite perfectly in focus, but I love the composition (totally timed it this good on purpose)

...and this one is just for fun. Anne isn't so big on actually swimming, probably because she isn't super talented at floating just yet...

Some stills I grabbed from this lens’ first real excursion. Taken at the San Bernard National Wildlife Refuge.

There's a small crescent shaped artifact in the lower left corner, which I first noticed in the duck clip. It's not very obvious in these individual frames, but during video it's quite obvious. Could this be solved by cleaning the exterior of the front and/or rear elements, or is this caused by a scratch or internal defect? I really like this lens and don't want to return it, but if this issue is unfixable I might have no choice.

EDIT: It’s a camera issue, the crescent appears with my Sigma lens, too. It appears to be caused by a piece of lint.

A few from today. I first went out looking for birds; not much was going on other than these mallards sleeping in on a Sunday morning (taken with the 1.4 teleconverter).

Met up later with friends and family and took a walk to another pond for more C-AF practice. As I now have plenty of similar shots of my pup, I focused more on my brother's dog Cannoli, which is actually the half brother to mine. As long as I did my part, the camera did a pretty good job of locking on to what I wanted- these are all with the M1 mkI. Those ears, tho...

Nice, sharp shots Paul, but they are severely underexposed. You may want to add some positive EC either in-camera, or in post.

Thanks- they looked fine on my laptop but a little dark on my phone. Guess that tells me where the problem is, especially since my first steps in post were to bring down the exposures...

A few faces from this year's Chinese New Year parade in Manhattan's Chinatown. There was a light drizzle falling most of the time and the sky was heavily overcast, but the bright colours of the costumes and flags and the speed of the lens helped make up for it. All images were shot at f/2 with C-AF on the E-M1 mk II.

Am I crazy or do these look a few stops under-exposed?

You may or may not be crazy, but chances are they look underexposed to everyone but me. I do my post processing on an old non-HD laptop that's on it's last legs; Ian pointed out the underexposures from the last batch so I'm now double checking my work with my phone. How's this one from today?
