I tend to view these mobile phone lens adapters as gimmicky plasticy junk that just sits in a drawer somewhere after being used exactly once... 9 times out of 10 that is the case. Not this time! This cool device essentially turns your phone camera into a digital microscope. The addition of a ring light around the lens is crucial here and the execution is well thought out. The ring light enables your subject to be in full light even when the lens is literally sitting on top of the object you are viewing. I used a piece of cloth as an example. The first image is at the standard 1x from my Pixel 8 Pro. The second image is using the same 1x camera on my phone but with this 150x lens adapter in front of it. The results are insane and totally unexpected! I can't wait to try this lens out on more objects around my home. Highly impressed! 5/5

simply to use, green light comes on when connected!

bought the adapter because I also want to use my existing Nikon lenses on the new BMPCC4K. Since the vast majority of lenses have an aperture lever, they can also be used although they do not have a separate aperture ring (lenses without an E-mark!). The adapter makes a very valuable impression. It is made of metal and feels good in the hand. It easily connects to the camera and lens. I haven't found any game so far. If this occurs during use and possibly leads to scattered light, I will provide an update. The adapter is delivered in a small plastic box. This makes it easy to store or transport when not in use. The silver ring is used to set the aperture. However, there are no numbers, only a symbol for an open and one for a closed aperture. But you can see directly on the display how turning the ring affects the brightness. So I don't miss numbers. In addition, I have read on other adapters with numbers on the ring that these values are not as finely graded as the numbers make it seem. I am very happy with this adapter. Of course, you lose light intensity because every assembly between the lens and the sensor "swallows" light. But this adapter only costs a fraction of what a Speed Booster costs. Also, you can't get a speed booster with contacts for Nikon lenses. No information is passed on to the camera, so you have to set everything manually even when using a speed booster. I can highly recommend this adapter to anyone who can get along with a somewhat lower light intensity.

First impressions: - good looking - fine workmanship - matte interior finish (light doesn't jump in) - smooth conformance to camera body - smooth shift rotating One ring - comes in an unsealed hard case and nothing else on it - out of the box with any vintage Nikon mount usable lenses - orange ring gives the looks to the whole camera setup - the adapter fits harder on the lenses (needs to be attached) - focus is based more on the depth of field (FOD) difference in the picture frame - it works more like zone focusing and precession focus zones are heavy to reach - metal mount on lens side and (I think it's still a metal) black plastic which looks nice, camera charcoal mount (it's passive adapter and therefore no electrical communication between lens and camera) - light doesn't get through the adapter into the Barrel (sealed fit) - it should come with end caps to the adapter to keep dust out when not in use - for the money I paid I like experimenting with my old lenses on the Sony mirrorless body

This feedback will be given on initial discovery and has not been used in the field. The pinpointer gives a single green light upon FINDING the item, and increases to 3 lights when it is upon the item, so I hope that helps you understand my wording.

It found the penny 1" away, a nickel 3/4" away, a dime 1" away, and a quarter 1" away. But these were on a flat surface as the pinpointer approached from the side. If I hold these coins upwards so the pinpointer approaches the largest surface area, these numbers change:
Penny= 2"
Nickel=2"
Dime=1&3/4"
Quarter=2"

I, myself, am new to the hobby and will update with a proper review in a bit. Thanks for looking!

This streak filter can be rotated up to 360 degrees and is perfect for creating differently angled and dynamically rotating flares. The anamorphic streak filter from K&F Concept creates a cinematic vintage effect on photos and videos by transforming points of light into linear anamorphic light reflections. It has a 77mm camera lens with a mounting thread. With an adapter ring, a step-up ring or a step-down ring, it can also be used for camera lenses from 32mm to 82mm. It is equipped with 8K Ultra HD optical glass, has 28 nano-layers and low reflectivity that ensures high-resolution photos and video recordings. It is lightweight and consists of an anodized aluminum alloy frame. It has an ultra-thin frame that reduces vignetting and dark corners when mounted on a wide-angle lens. CNC machined and anodized aluminum alloy frame is built to last, abrasion and erosion resistant. In addition, the trapezoidal pattern on the frame is ideal for easier grip and non-slip function. The filter is excellent because it is waterproof and oil resistant. I like the fact that the lenses can be rotated to adjust the angle of the spread. Also, the brightness and intensity of the filter will depend on your setup and the light you're shooting. The compact effect filter comes with a filter box and a cleaning cloth, making it efficient and practical for your recording and filming. All in all, this is a great product that allows me to be more creative in my photo shoots with less effort.

CO detector has a stand and shows CO level, green light, temp, and humidity. We set it up and after a couple days it started beeping as it was not plugged in. Not sure of accuracy of CO, but temp and humidity seem correct.

and can be charged with USB c. only when the drone is in the air do the flashing LEDs not help. the drone is barely visible.
