Falling in love with Four Thirds lenses (Lots of Images)

The biggest problem came to AF when I test it on my E-M5 Mark II (which should have similar AF performance to E-M10s), it was utterly useless, it was sluggishly slow (like more them 5 seconds), it gives up more often then not and when it thinks it locks on it actually front focuses. So I can use it only with MF and all the images above with that lens are manual focus.

Before I got my 2nd EM1 I was trying to photograph baby gators with a fisheye lens so I had to put my EM1 with the fisheye lens out in the water because I couldn't control the EM5 remotely.

EM1 w/ Bower 7.5mm Fisheye by Phocal Art, on Flickr

While waiting for them to get close (which they never would approach the camera, despite being more than willing to swim right up to me on the bank) I threw the 50-200 SWD on my EM5, which was the first and only time I have ever used the lens on anything but an EM1. Mine would also front focus every single time which forced me to manually focus it. Trying to manually focus the lens for this photograph was a pain in the ass because he was very close, DoF was very narrow and he was never really sitting still (always moving forwards/backwards). But I did manage to get what is still my favorite baby gator photograph.

You are correct, the only adapter that is weather sealed is the Olympus MMF-3.

Yes, the only COMPLETE weather sealing option is the Olympus MMF-3. I wanted to test Four Thirds performance and image quality before investing in a better adapter, a 25 pounds Viltrox is not much loss IF I wasn't very happy, hence why I also went with the Mark I of Olympus 14-54mm. In total 150 pounds experiment is not exactly the cheapest idea BUT I can use the Viltrox adapter on non-weather sealed Four Thirds lenses later and get the MMF-3 (a combo with Olympus 50mm f 2 Macro or 70-300mm f 4-5.6).

On the quality of the adapter, well it's cheap so its light aluminum, I bought 2 accidentally but one doesnt seem to work well because it keeps losing contact with the lens so if you can get it with good refund or return policy then go for that option.

Awesome image. I understand your pain, I find it difficult at times to focus precisely and my keepers are far from 99%. The issue I have is because its Focus by Wire the most minute changes in focus to get that pin sharp is not precise or reactive because of the nature of Focus by Wire. Still, I shoot most of the time, about 90%, wide open and use High Burst to increase the chances of getting right shot. Also when I am close to the minimum focus or I need the tiniest of changes in focus I move back and forward physically and very slowly and combine that with Burst.

Even for a 250 pounds manual focus zoom I am so happy about the image quality and do not regret the purchase. I wish it was a bit smaller and lighter (well that's Panasonic Leica 50-200mm f 2.8-4 but my wallet is threatening me with a heart attack if I try anything funny :p ) but I get 100mm to 190mm with constant f 2.8 and the 400mm f 3.5 is the cherry on top of the cake.

Just a note for interested parties who might read this thread and want a ZD 50-200mm. Only the mk1 version of the lens is focus by wire. The mk2, "SWD" version has mechanical coupling to the focus ring, so not only is it real mechanical focus, it is also full time mechanical focus when you need it (no need to set the camera to SF+MF mode to have both AF and manual focus available).

Exactly my experience with the 50-200 on the E-M5. Front focus every time, and relatively worse the farther away the target was.

Bought the non-SWD 50-200mm f2.8-3.5 2 years ago and never looked back. The optical and build quality are superb and suits my purposes. Some nice pix from the OP.
