The filter is really good, it seems to be a real 10 stop filter (some ND1000 are only 8-9 stops, which makes shutterspeed calculations hard), it is reducing light in both Visible and Infrared light (has been tested on a full spectrum camera used for Infrared Photography), so you will not have a nasty discolouration in the sky as with other ND filters, but you will get a slight blue colour cast, nothing that can not be fixed in post process with the white balance tool, but I highly recommend doing a white balance setting with the filter on to get accurate colours, especially if you are shooting in JPG. I did not see any reduction in detail (see the 100% or 1:1 crop). It easily screwed on my lens and step up rings as well. It has a nice grippy area which I find giving a much better grip than other filters. One thing I'd like to mention is the case it's coming with has a nice locking mechanism and also two carve outs to be able to easily remove the filter from it's case, actually it's one of the best cases I've seen, beating the nice metallic cases from Gobe, which does not close well with larger filters.
If colour cast is a critical issue for you then this filter might disappoint you with it's blue cast, in that case I recommend Haida's NanoPRO ND1000, which I unfortantely lost, but that has virtually no colour cast at all, but nearly triple the price.

The filter quality seems to be perfect. I'm used to that from K&F Concept. And you get a really nice blue streak effect. The problem, however, is that you get that with every single light source in your image, so you don't really have the ability to be selective. You have to compose your recording really carefully. The filter rotates smoothly, allowing you to change the direction of the stripes, but you'll still see them in any light source. I think in the end Photoshop is probably the better option to give you more control over such effects. Still, it's a worthwhile tool to have in your toolbox, especially given the cheap price for an FX filter. It uses the same high quality optical glass as the other newer filters. The precision machining of the filter threads and ring is impressive and gives the feel of a much more expensive filter. So I can't fault any of the properties of the filter. It's just for the way I shoot, it probably won't be as useful as for some other types of photography.

Very good 77mm blue streak filter. The blue steaks can be rotated 360 degrees, which means you can point the light spots in any direction you want to create some very interesting effects. The images I've added are an example and were taken in the same spot I just rotated the filter to show how it works. So far I haven't had any issues with removing the lens filter that you can get with a rotating filter. I'll admit I didn't quite understand how this would work and tried using it during the day on a cloudy day and obviously didn't get anything, but I can confirm that this filter does the pictures I took has not affected, so you can put it on your lens and as long as there are no lights, everything is fine. For this to work you will need a light source, street lights, car headlights, wall lights, etc. BUT note that you cannot choose the light source. So if you have multiple lights you will get the flare effect on all the lights. I tried this on an 85mm lens and with the lens filter on I was still able to attach and detach the lens hood as normal. The filter doesn't have an overhang on the lens, but that probably depends on the lens you're using. Overall I am very happy with the Blue Streak Filter and would recommend it to anyone wanting this effect.

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.

You need some good, sharp highlights, e.g. B. if you point it directly at a bright light to get the most out of it. When you do that the effect is great and it's good at mimicking the blue streaks you get from anamorphic lenses. You can rotate it to any angle, which is handy for switching between portrait and landscape modes, but anything other than horizontal stripes looks odd to me. Probably just because we're used to seeing that in movies. Aside from the blue stripes, it's otherwise very clear and hardly detracts from the rest of the picture, which is great.

All in all a very good camera for the price!

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.

I love this 4G LTE Solar Camera! We put it over the garage door pointing down the driveway and it was so reassuring that a few weeks ago my son heard a noise outside and came down the stairs to investigate. The security light was on and he also turned on the downstairs hallway light. Later the next day, when my son was telling us about the incident, my husband looked outside and we noticed that the door frame had markings that alarmingly resembled a crowbar inserted into it. That was obviously annoying, so this camera was a very welcome addition. I love the fact that it's big and very obvious and there's even a setting for it to set off an alarm which is pretty loud when it detects movement.

The picture quality is really good, nice and crisp and while we haven't used the audio function it's good to know it's there. I, for one, feel a lot more comfortable knowing that we have a security camera in the driveway that alerts us if someone approaches the door at night, and we can view it at any time from the phone app.

We haven't encountered any issues with this camera and have been very happy with its performance so far. With that in mind, I wouldn't hesitate to give this a 5/5 rating
