I'm certain that the blur I'm seeing is not atmospheric blur. I've tested the lens at shorter distances to rule that out. I also shoot in electronic shutter mode so shutter slap should be a non factor. The vibration is mostly from wind I think.I've used much longer lenses with film cameras for years, so digital cameras are no panacea. The options to try vary depending on what you have. You've got the tripod, but when I've used a 800mm f8 Yashica "beast", I used one tripod for the camera body, and another for the lens (which has a tripod socket as well). I also use a cable release, and mirror lock-up. With digitals that have anti-shake -- turn it off -- as you mentioned. If the setup is stable the shutter speed should not be a big deal. Try using the B setting and a piece of black paper in front of the lens as a shutter to remove the camera as a suspect.
Are you sure that the "motion" you are seeing is not "atmospheric blur". Try some test shots in bright conditions of a contrasty subject (Ex. Street sign) at the end of a "football field". Start with a FAST shutter speed and slow it down and see when the motion shows up!
FYI, analog "cuts it" fineI

Thanks, I must have read that but just forgot. Need to see if remain true for the A77II and A99II. My Quick Set Husky is pretty solid. but when using a monopod I will keep steady shot on.Here's what Gart Friedman has to say regarding the Sony SteadyShot in his Sony 900/850 book:

I've also read that if IS in ON in the body and ON in the lens at the same time, bad things can happen. Not a problem for me -- even if there is some truth to it

I have several lens that are longer than 500mm, yes atmospheric turbulence tends to spoil distant shots, but it's not too bad over moderate distance
That depends on the system. My Pentax has in body shake reduction & I have one lens for it the has OS, but neither is aware of the other, so both on is much the same as neither on. Any movement is canceled by one & then introduced in the opposite direction by the other.
More modern systems can have the two systems working together to give better stabilization than either along. I think Olympus was the first to offer a dual stabilization system, though others have since followed.
No problemThanks for clarifying that -- even though it's irrelevant to me, it's probably useful to others. I'm glad that my cameras have IS in the body since I use a lot of manual focus lenses -- no IS in sight. This is especially true for my LONG lenses. My longest telephoto lens is a NON-IS 600mm, and passed that they are all CATS.
Speaking of the pre-IS era, I note that Fretag says to use a red filter for the Hasselblad 500mm lens to reduce atmospheric problems.
