For A-mount lenses, there's another permutation of SteadyShot support to note: the a99ii has introduced 5-axis stabilization.

Some lenses support 3 axis (pitch/yaw/roll) and others support 5-axis (pitch/yaw/roll/x/y). I've gone through the sony compatibility list and made the following notes:

All Sony and Sony Zeiss branded A-mount lenses support 5-axis stabilization with the a99ii except the following:

20 f2.8
16f 2.8 fisheye
28f 2.8
500 f/8 reflex

On the Minolta/KM side, the vast majority are 3-axis only. Here are the Minolta/KM branded lenses that DO support 5-axis:

Primes:
135 STF
300 f2/.8 SSM
85 1.4 G D
85 1.4 Limited
50 Macro original
100 Macro original
50 Macro RS
100 Macro RS
50 Macro 3.5
200mm Macro G
50 Macro D
100 Macro D

Zooms:
35-70 f/4 (original)
28-85 f/3.5-4.5 (original)
28-135 (secret handshake)
35-105 (original)
28-85 f/3.5-4.5 RS
28-80 4-5.6
100-300 D
24-105 D
70-200 SSM
28-80 D
75-300 D
28-100 D
17-35 D
28-75 D
18-70 DT
11-18 DT
18-200 DT

The MInolta 3x-1x Macro zoom is recommended to have Antishake/Steadyshot turned off.

Can this information be implemented into the lens database in some way?

Unfortunately there is no way to know about third-party lenses (that I know of).

It looks like all the D lenses are supported which makes sense. That is the information that the camera needs for the x and y axis. I bet that is also true for third-party D lenses.

I am not sure what to make of the non-D lenses listed. They may have just forgot to add the text. It would be the opposite of how it claims every Minolta lens doesn't support Lens Compensation, when several Minolta lenses are corrected by Lens Compensation.

By perusing every entry on Sony's lens compatbility list.

Sony sight
"ILCA-99M2
Compatibility Information

Hybrid Phase Detection AF system"

Perhaps, I don't see how the AF has any thing to do with the 3 axis or 5 axis lens stability?

You have to click on EVERY lens to see what kind of stabilization is NOT supported. Try the 16/2.8 Fisheye:

•Shake compensation is available with 3-axis(Pitch/Yaw/Roll) by SteadyShot INSIDE.

Very good kefkafloyd, you really are "some one"!

I made a humble approach to do a lens table myself, but after having looked at some lenses in the A99 II Compatibility Information page, I was soon attacked by lazyness and thought I perhaps could evade going through every lens in the chart, so I made a suggestion...

to you kefkafloyd !

I'll be back later for a (hopefully decent) explanation to one of your questions in that other thread. I have some troubles sitting in front of the computer because I am old and suffer from spine pain, so now I am off to bed to ease the ache.
See you!

I don't understand this 5-axis concept.

At sea, one dealt with five forces, plus seasickness.

They were Surge, Heave and Sway. They are all linear movements....side-to-side, back-and-forward, up-and down. I think of them in relation to the ship's course. I think this is in-body image stabilization using primarily heave and sway

Pitch (Y) and Yaw (X) are considered rotational movements, as is Roll. Pitch means one's head stands in place and the front of the lens moves up and down. Yaw moves the front of the lens side to side, with the head holding still.

Roll on a camera is corrected by the photographer using his artificial horizon. Surge is used by us constantly when handholding the camera and moving our head forward and back.

So one should really talk about surge, heave, sway (x yaw)(y pitch). But I am dubious in the extreme whether the additional 2 x and y axes makes any appreciable difference to the excellent Sony stabilization scheme. I think it's just advertising hogwash.
