It's great to watch your baby
This is used to look at the baby, you can see the baby no matter where it is. You can see clearly at night or during the day, and you can talk to your baby through the camera, so that you will not miss your baby's every move.

Some instructions would be nice.
A great buy really. So many different options for the gopro. Would be nice to have some instructions though, as many pieces require some assembly and different attachments using, and unless you're knowledgeable in such things it can leave you scratching your head a while.

A good purchase
Excellent night visionCamera works great! The connection is a little slow at longer distances, but it doesn't affect usability. Setup should be pretty easy for the experienced, I was using it for the first time and thankfully my husband figured it out quickly.

Q
is there a 72 adapter ring?
A
No! Only:77mm; 67mm; 62mm; 58mm; 55mm and 52mm 
Q
Will this work with the pentax mount asahi takumar smc 50mm 1.4?
A
Yes. I have the same lens and adaptor on my Sony a7ll and it works beautifully. The m42 is also known as the 'universal' mount as other 3rd party camera and lenses also used it. I own 6 other K&F e-mount adaptors to different lens makers (ltm, MD, CF/CD, Nikon) and they all are well built with a nice snug fit. Highly recommended. 
Q
does this fit pentax cameras?
A
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 
Q
Pentax pk mount usually means pentax k mount which has a flange distance greater than m. is this adapter for adapting leica m lens to pentax q camera?
A
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. 
Q
Is the K&F Concept adapter for Pentax PK K mount to Sony NEX e-mount compatible with the Sony A6000? Does a P-KA mount adapter exist?
A
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).
