After much research and thought I recently purchased a new Sigma 150-600mm Contemporary Canon mount and a FotodioX Pro EOS to NEX Auto adaptor. I'm hoping to use this set-up eventually on a new A7rII, but was excited to get going with it on my old NEX-7. It all hooks up, but there is a lot of play on the NEX-7 mount. There is no auto focus at all, or aperture control. When I loosened and relocked the camera I could get aperture control to appear for a few seconds. I called Fotodiox and was told there should be no problem using this lens/camera combo so I returned the adapter to Adorama and got another one. The second has the same problems, but I was able to get aperture control for a longer period, but never managed to get a picture taken before it reverted to wide open.

 

I don't have a Canon or  A7 body to test the lens with, but will try to get ahold of at least a Canon to see if there is a problem with the lens.

 

Anybody have experience adapting Sigma zooms to any A7 bodies or NEX? After reading Brian Smith's adapter review page I was hoping the Fotodiox would work.

      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.
