Q
Can the lens aperture be controlled with this adapter? I am worried that I won't be able to change aperture values as there don't appear to be any electronics.
A
Hello,although the lens will fit physically, automatic diaphragm, auto-focusing, or any other functions will not operate while using this adapter. There is no electrical contacts in the adapter ring. Full manual operation, manual focus, manual iris adjustment can be achieved with body manual exposure, aperture priority exposure. 
Q
Does this solar outdoor camera record continuously or only when motion is detected?
A
this solar outdoor camera con only records motion detection, can not record continuously or auto-tracking. Tip: the floodlight will be on when Humanoid motion is detected in the dark, there will change to color night vision. 
Q
Will this work on my sony a6000 and tokina minolta 100-300mm macro zoom?
A
Yes 
Q
Too loose/there is gap between lens and adapter ring
A
  1. If there is ever any more than a slight amount of rotational play, you may want to try tightening the lens mount adapter so it will hold the lens tighter to the mount. There are 3 flanges in the middle of the adapter (what the lens locks onto) that are split open slightly, this gap is what gives the tension that holds the lens tight to the body. Over time and with use these gaps decrease in size, no longer pulling the lens tight to the adapter, which allows the lens to move inside the mount more than it should.
  2. To tighten the fit, get a slim metal object (a #1.5 or #2.0 small flat eyeglass screwdriver is ideal) and insert it into the slit to open it up just a little bit (see images below, make sure to do it to all 3 evenly). The more you open the gap, the tighter the lens will be to the adapter; too much and the lens will have a hard time mounting so make sure to do it just a little bit at a time to all 3 flanges evenly, it doesn’t take much at all to get a tight fit.Note: please do not use too much strength, or the shrapnel will be damaged.
 
Q
What kind of rear and front caps would I buy to go on this since it doesn't come with any?
A
I don't think you need any. There is no glass.
