Great little camera
Great camera used it on multiple occasions. The camera screan is small but works. Pitures look blurry on the small screen but come out great when put on a phone or computer. Comes with all the attachments and then some. Used on a five day back pack trip and took 30 photos never hat to replace the battery or memory card. The waterproof case really does work. Only negative is it is sensative to cold temperatures (ex. 35°F) will still recored but drains battery and has to warm up before it turns on again.

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.

Extremely Happy with Both Lenses
Great product! Extremely happy with the quality.- It comes in a small carrying case with a clip. The two lense and lense caps, a clip, a wiping cloth, small light, lanyard. The clip has a soft barrier so won't damage your phone. Very easy to use.- The quality of the zoom lense is great, takes very minimal effort to focus. Great for capturing details in plants and bugs (my main purpose for this purchase) but don't expect to capture microorganisms ha!- The wide lense is also good as it does help to capture more than with the bare camera. Using the back camera always has better quality so it's perfect for selfies and great at capturing everyone and still seeing the back scenery.*see pics... enjoy!

Delicious Variety Pack
This variety of flavored coffee is delicious! There is something for everyone who enjoys flavored coffee. Would recommend to anyone that enjoys trying different flavored coffees. The mystery cup, still not sure. I was eager to try but there was a mishap in the machine so I couldn't drink it since my cup was full of coffee grounds. Maybe next time. This is a definite buy again.

Q
Will the autofocus function of the lens be affected after using the adapter ring?
A
The adapter ring itself does not contain any electronic components, so it will not affect the autofocus function of the lens. 
Q
is there a 72 adapter ring?
A
No! Only:77mm; 67mm; 62mm; 58mm; 55mm and 52mm 
Q
When used with telephoto lens, the adapter ring may be loose
A
That may be caused by the fact that the lens weight is much bigger than camera, If used your telephoto lens with our adapter ring, we suggest to use with a lens bracket and better to shoot on a tripod to increase its stability. 
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
Can i use this on a 95 mm lens without an adapter ring?
A
It can't not be fixed well with the lens without the adapter ring. you should buy another adapter ring of 95mm size if you want to make this square filter fixed on the lens.
