There actually are several of the Sigma 150-600 lenses, apparently with significant differences. I bought one recently for the Sony E mount and one question I directed to B&H was how the camera settings interacted with the lens settings. They really did not answer the question but simply said stabilization would be either in the camera or in the lens. But when you turn on stabilization in the lens does that automatically turn it off in the camera?

It seems I have some experimenting to do now that spring is on the way.

Read the manuals for lens and camera. They will explain in excruciating JEnglish what you need to know.

WOW George, imagine what the world would be like if everyone used your technique. We all would have more time, there would be a much smaller internet and the whole political arena would be habited by different people.

I hear you, Toby...

I approach most of my entire life with that philosophy... When I speak, and/or write, I try to be able to "Point to something" of authority and/or expertise which supports what I say or write...

Then my next response is......... I am just the messenger, and point again to my source of authrity

ha ha ha

I doubt that the camera manual could shed much light on how the camera would interact with a lens that did not even exist when the manual was written. As for the lens manual, it consists of a single sheet of paper printed in 4 point type. It mostly consists of diagrams and very terse descriptions. It certainly does not discuss any subtle interactions with the camera.

But after scanning and enhancing the print to make it readable I did read it multiple times, thoroughly. It had nothing to say, in English or in Jenglish about interactions with the camera - and I used to work for a Japanese company and am reasonably able to interpret Jenglish. I do recall that it recommended turning off stabilization (presumably by the lens) when used on a tripod.

That is usually the case when "in-lens IS" is involved, especially with older Canon and some Sigma and Tamron IS/VC lenses.

Where it gets especially weird is when you have in-body and in-lens systems from different manufacturers. Generally, in-lens systems work best at focal lengths longer than 140mm full frame equivalent. In-body systems work best at the shorter range of full frame equivalent focal lengths. That knowledge may help you decide which to turn on or off, and when.

The exception is when you have a long lens on a body made by the same manufacturer, and both are stabilized AND engineered to work together in tandem. Lumix makes some longer lenses with integrated OIS (optical image stabilization). Their latest bodies are also very well stabilized, and they have a "Dual IS II" system that takes advantage of both in-body and in-lens systems. You can leave both forms of IS ON when using Lumix or Panasonic Leica lenses on Lumix bodies, and the combination will give you the best of both worlds — IBIS will handle the shorter range and ILIS (OIS) will handle the longer range of focal lengths.
