Fotodiox Tough E-mount – Sony A7R and A6000

I ordered 2 of the Fotodiox tough E-mount adapter about two weeks ago, to replace the original mounts on my Sony A7R and Sony A6000, as both cameras have significant play with a lens is mounted. However, it has to be said that this has not impeded their ability to function and produce great photos.

In this post I thought I would compare how well the cameras perform with their native mounts compared to the tough E-mount i.e. does it hold the lens firmer and does this translate as an improvement in handling? Read on to find out.

Below are the pictures of the dismantling of the original E-mount from the Sony A7R and then of the two cameras with their tough E-mount on. The difference between the two cameras is that the Sony A7R has double-sided tape holding the E-mount plastic portion in place, whereas the Sony A6000 does not.

My observations:

1) The Sony A7R there is definitely a significant improvement in tightness of fit and definitely does not display any flex.

2) This however was not the case for my Sony A6000, which still exhibits some significant play.

3) My Phigment Tech Leica-M to NEX adapter cannot be used with the tough E-mount, as one of its tabs does not fit through the tough E-mount (nearest the white alignment dot of the camera) and will need filing away before it can be used. 

4) Previously with latest firmware on my Sony A7R, my Sony 85mm F1.4 Planar Zeiss lens with Sony LA-EA4 needed -13 micro AF adjustment. With the tough E-mount, this is now set at +18.

5) There is no light leak with either camera with a camera body cap on the tough E-mount. But then this was not a problem I had with either camera anyway.

6) If changing the mount on a Sony A7R, I would say the tough E-mount can be recommended. But that is not the case for the Sony A6000. I suggest looking online for reviews of this tough E-mount on your specific model, before taking the plunge.

Future tests to come:

1) Test of various NEX adapters I own to see if they retain infinity focus. This includes the Phigment Tech adapter, Hawk Factory Leica-M to NEX helicoid, Pixco Nikon G to NEX helicoid, Kipon Contax to NEX adapter & Kipon Nikon S/Contax C/Y to NEX adapter.

2) I will check to see if improving the stability of the mount on the Sony A7R will result in an improvement in the image quality at the corners (assuming that any flexing at the mount is completely negated with the tough E-mount), with the lenses I have (Sony 85mm F1.4 Planar Zeiss, Sony FE 24-70mm F4 Zeiss and Sony FE 70-200mm F4 G lens).
