I can't seem to find the answer anywhere about this use case.
I am using a 18-35mm Sigma F1.8 apsc lens adapted to Commlite smart adapter with my a7sii.
1. When I am shooting in APSC (Crop) mode, is the camera smart enough to read the Sigma focal length distance from smart adapter to determine suitable image stabilization settings?
2. If i have to use manual focal distance settings (In CROP MODE), do I just select 18-35mm? or do I need to put in the apsc focal length equivalent 27-51mm?
3. I am unsure if I am using a FF lens at 135mm with manual IS focal length set at 135mm, if I go into crop mode do I need to adjust the focal length to 202.5mm?
I suck at math and hopefully camera is smart enough to do it for me lol!
Thanks for your insight and help!
