The bike camera is similar to action cameras, Its 4K videos and 20 MPs, it has image stabilization, it has one button control to recording videos and shooting. It's not hard to use. The difference is this is designed to mount to your bike. really you can mount it to anything the bar clamp will fit on. You can also mount it on tap a helmet. The quality is really good. Video looks great. It records to a 64GB micro SD card which is included and you can use a card up to 128GB. There is a two inch screen to watch the video. Battery life is very good. There is a bike horn and light built in. There are three lighting modes. If you are looking for an action to add to your bike, this is it. I can recommend

Looks good so far!

The K&F Concept universal cell phone camera lens set is perfect. I'm often by streams and especially around midday the shots are always a bit bright.... I've often heard that you can get a lot more out of an ND filter. The clamp holds the filter securely over my P40 Pro, even with a thin case. The filter can be easily adjusted with the clamp. Since you can adjust the filter, you should take the time to experiment a bit. It's worth it! I was able to create much better saturation. It comes in a sturdy, sealable plastic case and can be stored in my gimbal bag. I'm very satisfied. For me as a YouTuber, it's an inexpensive, simple improvement in video quality. Happy to give it 5 stars.

I bought the K&F Concept Universal Cell Phone Camera Lens Set with Filters for my iPhone and I'm very happy with it. The set includes a 52mm variable ND2-ND400 filter that allows me to easily adjust the exposure and shutter speed of my cell phone photos. The quality of the images improves significantly, especially in bright light conditions or when shooting moving subjects. The filters are easy to install and fit perfectly on my iPhone. Overall, I'm very happy with this lens set and can recommend it to anyone who wants to improve their phone's camera.

The filter works excellently, as I know it from my SLR camera. Since I don't have a GoPro camera, I had to make an adapter ring to attach the filter to my action camera.

Analogue lenses have character and charm - that's for sure. And they are often many times cheaper than their digital counterparts. So why not adapt the good "old glasses" to a new camera? I already own the Neewer adapter for my Minolta glasses and now I wanted to test this K&F lens adapter for my M42 lenses on my Sony a7III and a6300. Today I also added the Minolta(AF)-NEX adapter to continue using my old Sony A-mount lenses.

I placed particular value on the following two points: quality and function.
1. Quality:
At this price (Minolta AF or Sony A-Mount), you can expect a little more from a lens adapter. To get straight to the point - my expectations were fully met.
Packaging:
The adapter arrived very well packaged and, in contrast to the Neewer adapter, even has a resealable plastic box. In this you can transport or stow it very well when you don't need it. Because we definitely don't want too much dust getting into the adapter and then into the camera.
Adapter:
The K&F adapter is made entirely of metal (brass and aluminum + a few steel screws). It feels very high quality and you have the feeling of holding something solid in your hand. The thread is very clean and well made. My lenses could be screwed in and unscrewed again without jamming. That's the way it has to be!
The fit on my Sony a7III with E-mount connection was very snug and tight. There was no wobbling or sliding after the adapter snapped onto the camera. It was also easy to dismantle thanks to the grooves on the surface of the adapter. This was thought through and not just valued for the optics.
The aperture selection on the Minolta AF adapter works excellently and feels "full" and easy to use. The f-stops therefore sit correctly and are not accidentally adjusted.
2nd function:
The adapter actually only adjusts the back focus of the "old lenses" to the new camera. He does this job excellently! Focusing to infinity works perfectly and the images are not affected by any additional lenses. Of course it depends on the lenses what the end result looks like - in my case I have the Porst wide angle 35mm f/3.5, the Auto Exaktar 135mm f/2.8 and for the Minolta AF the Samyang 16mm T2.2 used (see sample images).
I'm really happy with the K&F adapter and I'm sure I'll still have a lot of fun with it and my old lenses. I would buy it again anytime.

Edit 03/04/2019: I've even bought the Minolta(AF)-NEX adapter because I've only had good experiences with the products from K&F so far and I wasn't disappointed this time either. Great product and thanks to the choice of aperture I can now continue to use my old Sony A-mount lenses.

I bought and paid for the K&F adapter as usual via Amazon, but I get the money refunded as a product tester. As always, my opinion remains independent and honest.
