Picked up A7s recently, love it so much, and want to get one of the 150-600mm's seeing as how well they perform optically at the long end, I don't mind the slow aperture given the ISO performance on this camera.

 

That leaves me with essentially two options.

 

The Tamron 150-600mm + LA-EA4 adapter, which leaves me with no stabilisation (since Tamron did not put VC in the lens on the Alpha version?) if I understand, but fast AF right?

 

And the Sigma 150-600mm + Fotodiox/Metabones, which gives slow (next to useless as I understand it) AF, but gives lens based image stabilisation?

I tried the Sigma with Fotodiox on my NEX-7 before I got my A7RII, there was no communication between lens & body so no focus or F stop control. I tried another adapter with slightly better results (intermittent F-stop). I returned both for refund. Someday I'll try the Tamron with a Sony adapter.

      Bokeh?

      Shooting a cactus flower is probably where you do want to have nice bokeh. I can't recall which camera you're shooting, or maybe you haven't said, but using live view you can see what the shot will look like before you press the button. Try setting up on a flower or something stationary where you can control the background and see the changes different settings make.

      That's what I got from your post here: When shooting at f/11, bokeh is indeed not something you should be concerned with, unless when shooting closeup. Nearly all lenses have a polygonal iris shape at f/11 which naturally gives a more edgy rendering of out of focus areas. @Cameratose's example is perfect for demonstrating the relevance of bokeh. To some extent you can influence the backdrop of a shot, but if it is busy foliage relatively close by, it'd better not be distracting from your subject. Some lenses are able to create a more pleasing background than others, even at the same aperture setting and focal length. For the impact of the entire image one might even argue that the smoothness of the background is as relevant as the sharpness of the subject.

      Like Cameratose, I usually go for as much depth of field as I can, but sometimes there is no getting around out of focus areas, such as a closeup of a cactus flower.  I guess, everything else being equal, I might be concerned about a lenses bokeh, but everything else is seldom equal.  At this point in my photography I think I have bigger problems than unattractive bokeh.
