Yes, I have a NEX-7, two 6000s, an a7 and a 7ii. These batteries are suitable for all of the above and I believe should be suitable for travel. 

Please verify your camera's lens thread size(usually marked somewhere on the lens barrel or printed underneath the lens cap) before ordering.The number is always preceded by a "ø" (diameter) symbol 

I actually have not received this adapter yet. It's shipping from China. Don't think that was disclosed in the ad. However, I do not believe this is for the Pentax Q body rather for digital and film cameras that take the Pentax K mount in its many variations. So I'm expecting to be able to mount my Leica M mount lenses on my digital and film Pentax K mount cameras, no autofocus or relay of exposure information, only to be used with manual focus and exposure. 

I own a Sony a6000, basically the same type of sensor. Put a little fluid on the applicator which is made of soft foam, and sweet across the sensor a few times to clean. It works perfectly. Buy it! 

Yes it should work with the sony a6000. As long as the ka lens has an aperture ring on the lens and is not solely dependent on receiving aperture control from the body, this adapter should work fine with ka lenses. To my knowledge, there are no sony e mount to k mount adapters with electronic coupling so no lens control through the body (meaning aperture and focus are fully manual).
