You are right, and in theory it's a winning solution, although I would say that an E-M1/II would be a requirement to get autofocus that works well enough for anything moving faster than a turtle. The ultimate lens this side of $10,000 would then be the Sigma 120-300mm f/2.8 in EF mount, which becomes an 85-213mm f/2.0. Other alternatives would be the zooms from Tamron and Sigma that reach 600mm, or 426mm with the speed booster.
The problem with these solutions is that size and price approach that of a Nikon D500 combo, and the Nikon price can be reduced further by buying a D7200 instead, also a very decent camera that will focus faster than an E-M1 with a non-native lens, and light years faster than any other m4/3 camera with non-native lenses.
One solution that has not been mentioned so far is the 4/3 mount Zuiko 150mm f/2.0. It sells regularly second hand at around $1,500 and takes TCs very well, 1.4x as well as 2.0x. An E-M1 with that lens plus a stabilised Panasonic body with the 100-400mm would be a great combo, and still with a combined weight around that of the D500/200-500 combo....Show more →
AF, even with my Panasonic GX7 and Kipon adapter, while AFS only is pretty close to native fast and I think with some of the newest Oly cameras is faster (and is maybe a bit better with the Metabones smart adapters too).
The kipon adapter as it was first introduced was slow and had lots of issues but after a few firmware updates (both the Kipon and Metabones have USB ports) it is very useful.
I have not got the camera and adapter with me right now but it was even ok with an ancient EF 100-300 5.6 L (sold) but worked great with my (sold) Canon 135 f2 L, and also the Sigma 150 2.8 APO macro (mine is the non stabilized older version) which is still quite fast and a LOT cheaper than that 150 f2.
I also use the camera/adapter with my EF 100 f2, 40 2.8 STM and 18-55 IS ii kit lens (IS works well). It doesn't work with an ancient 28-90 kit lens from an old EF film camera.
I use the same lenses adapted to Sony FF which is slower to focus (A7s).
Only AF photo I have from the 150 2.8 with the Kipon and GX7 readily to hand has been posted a few times.
