Q: 5. I have a Lumix g7 and amm considering this lens or the panasonic lens of the same focal length. what would be the pros or cons of one lens over the other? They seem very similar.

A: While I have not personally used the recently-announced Olympus M.Zuiko Digital ED 100-400mm f/5-6.3 IS Lens, from reviews posted online, while both lenses are good options, the Panasonic lens would be more compact in size and offers better stabilization when shooting with a Panasonic camera that is compatible with their Dual IS feature. It is also nice that the zoom ring can be locked at any chosen position (the Olympus lens can only be locked at the 100mm setting). The Olympus lens offers better sharpness at the lens' maximum aperture, has better optical stabilization when using the lens on an Olympus body (the Olympus lens has better in-lens stabilization, but is incompatible with Olympus' in-body stabilization; the Panasonic lens' built-in stabilization is inferior, but offers better performance when paired with a Panasonic camera with in-body Dual IS stabilization capability). The Olympus lens would also be compatible with Olympus' 1.4x and 2x teleconveters (there are no teleconverters designed for the Panasonic lens). The zoom ring is much smoother to operate on the Olympus lens compared to the stiffer zoom ring on the Panasonic lens. All that being said, both lenses have good performance, so it would come down to personal preference.

Q: 9. When used with a Panasonic camera such as G9 or GH5, what stabilization mode will work? Can I turn off the lens stabilization and just use the camera's IBIS?

A: When pairing the Olympus M.Zuiko Digital ED 100-400mm f/5-6.3 IS Lens together with the Panasonic Lumix G9 Mirrorless Camera or the Panasonic Lumix GH5 Mirrorless Camera, you would have to use either the lens' built-in image stabilization or the camera body's built-in image stabilization, but you cannot use both at the same time. Dual I.S. stabilization using both the camera's in-body image stabilization and the lenses built-in stabilization is only compatible when using Panasonic-branded lenses on Panasonic cameras. As such, yes, you may turn off the lens' stabilization and just use the camera's in-body image stabilization feature. For more information, you may view pages 145-148 of the Panasonic Lumix G9 Mirrorless Camera's Owner's Manual for Advanced Features, or pages 143-146 of the Panasonic Lumix GH5 Mirrorless Camera's Owner's Manual for Advanced Features.
