Im sure this will all be solved with the A7 III :ROTFL:

No problem then, that'll be in another 3 or 6 months or so ...Im sure this will all be solved with the A7 III :ROTFL:
Yeah, a whole lot faster then Nikon's fix (in a Df) for their old manual focus lenses being able to fully meter with their digi cams. That only took 15 years? :ROTFL:No problem then, that'll be in another 3 or 6 months or so ...
Yes, that's the snag being at the blunt end of technologyYeah, a whole lot faster then Nikon's fix (in a Df) for their old manual focus lenses being able to fully meter with their digi cams. That only took 15 years? :ROTFL:
Cute!Yes, that's the snag being at the blunt end of technology
Vivek,Cute!
But the reality is that is one of their core business strategies ("planned obsolescence") besides denial.
The issue has been found and highlighted by David here. Let us see how Sony respond to that and how fast they do it. This will show the difference clearly.
At least Sony have finally found a use for the 16mm f2.8 pancake lens :ROTFL:So now I understand everything on this post.
One MUST buy a Sony non-OSS lens along with the a7II if you want legacy glass to work. So now the body will cost another $800 to $1000!!:lecture:
Sony must be laughing.:ROTFL:
Many thanks. Here is my question:
How well does the Sony IBIS perform when comparing native to non-native lenses of similar focal length?
So, how different behave the 5-axis versions for native lenses as compared to the 3-axis version for non-native lenses in terms of number of stabilization stops achieved?
TIA.
K-H,
I don't have the lenses to do the comparison you request, but the IBIS with a Minolta 70-210/4 , which is A mount with an adapter, works extremely well. 1/10 second at 210mm - how many stops is that? Over four? It's not tack sharp, so call it 3-4 stops. With a completely non-native lens, 50/1.4, 1/10 second is sharp, degradation sets in by 1/6 second. I'll spare you the Camapri bottle pictures. But that's about 3 stops.
The Minolta was shot under different conditions. I'll try it here now and see if those results hold up. It may be 3 stops with both.

Hello David:Hi thought I would start a separate thread about this issue I have been having so here is the text from the Users report thread. Any input would be welcome
Ok Guys so have got the new body and it is still doing it What I have figured out is that if I change from either FE24-70 or the 16-35 to an adapted lens IBIS won't click in. If I change from either the FE55 or 35 it will, so I am thinking there is a firmware bug. what maybe happening is that the camera doesn't seem to register when a non electronic lens is attached after a OSS lens has been attached. I would suggest others if possible try to replicate this. I have contacted Sony UK about it.Here is the text of the email
Dear Nick
Here is a summary of the issue as far as I see it
I bought the ILCE-7M2 last Friday the 12-12-14 and noticed on Sunday that at times that the IBIS feature stopped working when using a manual lens with an adaptor (voigtlander close focus adaptor or non specific Chines adaptor) with leica Rangefinder lenses. I noticed again yesterday that the IBIS had stopped working in these circumstances and thinking it maybe a camera issue my dealer (London Camera exchange in London) replaced it with a new camera. Unfortunately the issue is still there and I have narrowed down to when it is happening.
First scenario IBIS doesn't work with adapted lens
1. I have been using the 'FE24-70 OSS' or 'FE16-35 OSS’ and switch to a manual lens with adaptor
2. I turn on the camera and hear click and if I hold camera near to my ear I can hear a slight whirring
3. I dial in the correct focal length for the lens
4 On half press of shutter release the image doesn’t stabilise
5. I can turn IBIS on and off and there is no difference
Second Scenario IBIS works with adapted lens
1. I have been using the ‘FE55/f1.8’ or 'FE35/f2.8’
2. I turn on the camera and hear click and if I hold camera near to my ear I can hear a slight whirring
3. I dial in the correct focal length for the lens
4 On half press of shutter release the image does stabilise and behaves as I would expect
I am shooting RAW without jpeg and with batteries that are fully charged. All other functions appear normal
What appears to me to be happing is that when a lens that is not electronically in contact with the camera is used after the use of and OSS (Optical Steady Shot) lens for some reason the camera won’t activate the IBIS mechanism even though it sounds like is functioning. When using an adopted lens after using a Sony FE non OSS lens IBIS seems to activate.
It would appear that this maybe be a software bug as I am having the same issue even on the 2nd camera.
Yes I have tried this and it didn't workHello David:
I know I may regret getting in this late and I may have missed someone else asking this but I have a suggestion.
When you have an OSS lens on, before attaching the adapted lens have you tried turning stabilization off in the camera body before removing the OSS lens, then turning stabilization back on after attaching the adapted lens?
Regards,
John
Have tried this even for a few minutes and doesn't work for meAlso, could folks confirm post #14 of Sony A7II IBIS issue - FM Forums.
The claim is that removing the battery for a few seconds brings stabilization back.
I have seen no way to specify how IBIS works. The choices are On/Off, and if On, then Auto or Manual focal length setting.Also, can one selectively choose which group of the stabilizations to engage?
The three groups being, pitch and yaw, roll, X and Y.
Thanks again.
