EXCELLENT CAMERA
I am a former police officer. I work in Loss Prevention now.I use this camera at work in Loss Prevention and at home to back up my personal surveillance system. The video is excellent. Trigger time is fast.This camera takes clearer video than its cheap chineese counterparts.Its an excellent choice !

Great action camera for a reasonable price!
This was purchased for my son. He was asking for a small action camera for Christmas. I wasn’t comfortable buying a $300+ camera for a 9 year old. The Brave 4 was perfect. It’s a decent quality action camera at an affordable price. He loves it!

Family Photos
I was looking for something to use to take family photos without needing to rely on extra help to take the photos. That’s where this product comes in! I can setup the tripod anywhere, on any terrain, and take pictures using the included remote control while I’m in the picture. No more having to ask someone to be the photographer. Love it!

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.

Can't say enough!
I have only had the G5 model for a couple of days, but after trying a number of good rated blue tooth devices, both single a dual ear. This G5 is by far the most comfortable, secure fitting, easy to use one I've tried. It connects with my Android fast with no glitches. the sound quality was actually surprising. Even though It's been a couple days of use, it seems the battery is still strong after using off and on all day long. The only reason I'm going 4 stars on noise canceling is my wife said she could hear road noise during a driving call. Although the road I was on was quite noisy, so I'm not sure if 4 stars is really appropriate. I will update after more time if my experience differs. But all in all, I would highly recommend this earpiece!

Q
The adapter is Nikon f mount ?
A
Yes, it is indeed Nikon f mount.  
Q
What is the difference with the new sony sel-50f18f e-mount full frame lens?
A
One is for full format and the other for APS-C, whereby full format can also be operated on APS-C. 
Q
The difference between APS-C, full-frame, 4/3 sensor
A
  1. Adapting APS-frame lens to full-frame camera, it may generate vignetting, some cameras could correct it by adjust APSC, please contact us and provide your lens&camera model to check the way to correct it.
  2. Adapting full-frame lens to APS-frame camera (i.e: large format to medium format, medium format to 35mm, 35mm to micro 4/3) provides excellent edge-to-edge sharpness. The smaller image field helps minimize the effects of lens distortion and aberration by using the 'sweet spot' or center of the larger lens image circle. and it will magnify the focal length by 1.6 on Canon, 1.5 on Nikon and Sony，2.0 on M4/3 camera.
 
Q
Does this adapter allow for canon fd lenses to focus to infinity on sony e-mount mirrorless cameras?
A
yes, i had no problems with infinity focus with this adapter. the only FD mount lens i use anymore with my sony is a vivitar 20mm, and i pretty much only shoot infinity focus with it. 
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).
