Although the lens is designed for asp-c with a small image circle, zoom lenses will cover the ff sensor at some point as you zoom towards the long end.

I have the A7 and the SEL18200. Forget using it in FF mode.

First of all the lens NEVER covers the full frame (you get a heavy rectangular vignetting on the long end, I assume that's the plastic circuit cover the lens sports on the rear element).

Second, if you check the image at the borders, the details get quickly mushy outside the APS-C crop area. In crop mode though works well, if 10MP is enough for what you're doing and it's very comfortable to use if compare to let's say a NEX5N (my other body).

See here almost at the end of the page:

My cheap FF alternative for now it's a Minolta 28-134 F4. Good enough for a zoom, although a bit slow and without stabilization. 28mm is wide enough (on APS-C you get this field of view with an 18-19 mm lens).

Does SEL18200 OSS work on A7 ?


Apparently this one only works in crop mode. It is a 11 to 1 zoom ratio which probably accounts for the small image circle. Someone has surely tested all of the e-mount zooms. Maybe the short ratio 10-18 is the only one that works on FF.

I am sorry, perhaps I was not very clear on my question. What I was asking is that whether OSS feature of SEL18200 lens works on Sony A7. I read somewhere that it does not work, just wanted to confirm.
