As you and Jan have said, the 600/6.5 is a very good lens. Amazing how later
developments make it easy to use and get
good results.
Yea, I hated mine for years, and just about sold it on several occasions, but
now I find it behaves quite well on the OM-D E-M1.2 with silent shutter!
There was NOTHING I could do to not get tell-tale signs of shutter-shock on the
E-1, E-300, and E-3, although the direction of the blur was different on the
E-300, confirming shutter-shake. (The E-300 has a side-ways swinging mirror.)
I have a quite heavy tripod (Benbo #1).
I have the Uni-Lock reboot of the Benbo, and would call it a middle weight. My Bogen 3236 is Charles Atlas to its
ordinary body. :-)
I used it with TWO tripods, with a CF Gitzo supporting the end of the lens. I
put sandbags on it. I hung my camera bag from the tripod. There was NOTHING I
could do to avoid shutter-shake!
But with the E-M1.2 and IBIS, I can get reasonably sharp shots with it
HAND-HELD! Even of ETs!
Velbon El Carmagne 630 (about the same as the Benbo in solidity, but CF), Sony A7, let it sit a couple of seconds after
magnified LV focusing, shoot with wireless release, and there is NO vibration blur.
It is, in fact, quite sharp. Tricky to test shoot really long lenses. Quick and slightly dirty didn't give me much of
the corners, but the corner I got is pretty good. Center is excellent.

Interesting stuff, comparing lenses on different formats. Both the 600 and the PLeica 100-400 are as they came out of
the cameras. This copy of the 600 is much longer than spec in FL. The 100-400 is on a different shape/size sensor, with
different MP count - and they come out almost identical in pixel dimensions!
The Zuiko could use a little more contrast and the Leica a little NR, but, to my eye, they are identical in resolution.
The 600 is not that sharp at wider apertures; not bad, but not as good.
I shot other long lenses, a couple of mirrors and the built-in lens on the Sony RX10 IV. The Sony is the real surprise.
That's the long end of a 25x zoom, on a 1" sensor! WOW!
(BTW, the test target is my variation on the standard. I added smaller bars.)
As a practical matter, the 100-400 on µ4/3 is far smaller, lighter, more
flexible, etc. for the same resolution

I had forgotten that. Fun!
