    Posted: 06 September 2019 at 17:06
While the information likely exists somewhere, I haven't found it in any of my searches. My question is: does the IS on the a7II work automatically with SSM-SAM lenses on the LA-EA3, or do you have to put the focal length in manually? Same question for screw mount lenses on the LA-EA4, Any difference between 8 pin and older 5 pin lenses?

I'm at stage 2 in considering upgrading from my a7 body (stage 3 being the actual purchase). IS with adapted MF lenses is my primary reason for wanting to do this, but IS with adapted Minolta/Sony A mount AF lenses is another definite plus. If it has to be done manually, that's ok, but automatic would be nice.

I can only speak for the A7III but yes there is automatic relay of focal length.

I have found that the Tamron SP 70-300 USD does not behave reliably with IS on the LA-EA3 but is OK on the LA-EA4. (On longer focal lengths I sometimes have to dial in the focal length with the LA-EA3.) I don't see any problems with Sony or Minolta lenses.

Yes, SteadyShot Inside works with the LA-EA adapters and electronic adapters for other mounts.

According to Sony, the x- and y-axis stabilization requires a D lens (focus distance encoder). So only 3-axis stabilization for adapted 5-pin lenses. Current A-mount bodies might have x- and y-axis stabilization with these lenses as they seem to have internal focus distance encoders.

You can input focal lengths for 3-axis stabilization of unchipped lenses. You can also override the SteadyShot focal length for any lens.

THANKS!
I wanted to assume this was the case, but that is seldom necessary when there is such a pool of expertise on DYXUM!

That makes some sense to me. The Tamron borrows the lens ID of the 70-300G, but the lenses are very different optically. The Sony has a ton of focus breathing at the long end, and the Tamron has none.

From what I could tell playing with the focus distance limiter, Sigma's focus distance information implementation on A-mount is garbage at least in the lenses I have looked at--probably worse than nothing. I don't remember if I checked any Tamrons.

The Sigma MC-11 adapter disables SteadyShot Inside when a non-Sigma Global Vision optically stabilized lens is attached. I believe Sigma supports dual stabilization with their supported Global Vision lenses.

And by the way...
A delayed shout out to QuietOC. I purchased his used a68 to get eye-AF with my A mount lenses. The camera is much better than I expected. The size is what I'm used to, but still a bit lighter than the a77. Eye-AF with the 16-50/2.8 works and satisfies the whole reason for buying it. About the only time the EVF disappoints is when switching between the a68 and a99, otherwise it's fine. Condition of the camera was excellent, very happy with the purchase.

Thanks OC!

And...
Another thank you to jvandegr for selling me his Minolta 100-200/4.5. Such a little beauty. Forum rules won't let me post a thank you on the selling post, so I wanted to do it somewhere for others to see.

Thanks jvandegr!

You're welcome!

There is a big thank you thread hiding here. I am not sure why it is under External Sales & Discussion.

It is a shame Sony didn't promote the A68. It is a better camera than the A6300 that they heavily promoted at the time. But I expect the A68 costs more to make even with the cheaper displays.
