GH3 Little 'play' on my Speed Booster...

I just noticed that I have a little 'play' on my Speed Booster with the Sigma 18-35 attached. I can wiggle the lens slightly to the side when it's mounted. Also, when I apply a bit pressure / force, I can tilt the lens slightly (very slightly) downwards...

I just checked if it makes any difference in the image, and the image literally 'shifts' a bit to the left and right when I twist the lens. I do not see any difference in sharpness while zoomed in 5x.

My question is, does your Speed Booster does this? And is this problematic? Will it get worse over time? Or is this acceptable and no need for concern?

Thanks guys.
 
Mine has a slight wiggle as well but I've found a solution that will prevent the wiggle, and long term use of the SpeedBoster with the camera. I'll post a pic some time soon. Basically you could utilize any baseplate to prevent the wiggle and secure the camera with the SpeedBoster. In my case I use Kessler Crane Kwik release plate, but it should work with any tripod plate.

So I guess it's kind of 'normal' and I should just let it be like this. I still wonder if it actually affects the IQ more than it looks like at 1st sight. My biggest concern is that it gets worse over time. I guess time will tell.
 
I have a C/Y to M4/3 speedbooster with absolutely no play.

I also have an off brand EF to M4/3 speedbooster with the same amount of play I see in any of my EF mount lenses.
