Overall ok. Hard to tighten upper connectors to camera and to stop all movements. Needs weight to stabilize more. Manfrotto overall better tripod for $. Manfrotto packs to a smaller space and case.

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.For the price the K&F Concept ND1000 is unbeatable. It has just a very very slight blue colour cast, great IR filtering, true 10 stops and no reduction in picture quality. If you are on a budget and looking for an ND1000, look no further.

I like this camera it comes with a case.

Sure, extended to its full height outdoors, this isn't the sturdiest place to mount a camera. If you so much as breathe heavy on it, your camera will shake a bit. But for a commercial photography setting, this tripod has become a valuable part of my real estate kit. I have been using the Manfrotto XPRO series for years, and this tripod raises the functionality bar a whole step with the ability to invert the center column and shoot stable all the way to ground-level and even below if you need to shoot in a hole for some reason. I will still use my heavy aluminum X-PRO's for those windy days or when I'm sporting huge, heavy lenses like the Sigma150-600mm; but indoors and calm-air exteriors I've been shooting almost exclusively with this tripod in the week and a half since it arrived and I really like it. If it fails me at some point, I'll update.If K&F were to make a beefier version of this model, I would try to be the first to order it. Double-thick legs and heavier locks plus the 8-foot reach and to-the-ground shooting would put the Manfrotto line to shame.

simply to use, green light comes on when connected!

had fun playing with this Blue Streak filter. It creates blue stripes on your subject or, depending on the setting, light stripes. I enjoy capturing unique shots with the camera and this one is really great. It rotates 360 degrees on your lens, allowing you to rotate the strips in any direction. I have always been satisfied with products from the K&F Concept brand. The filter was clean and ready to use, which is a rare treat. It also comes with a durable carry case and microfiber cloth. Very happy with this filter.

This Blue Streak filter comes in a beautiful K&F Concept branded cardboard box (sealed in a plastic wrap). Inside the box is the filter, well protected in a handy protective case. A small cleaning cloth is also provided. The 77mm diameter frame of the filter is well made and feels quite sturdy. It screwed my lenses and step-up rings on and off with no problems. It also rotates smoothly so you can change the angle of the flare effect to your liking. The quality of the glass is also very good without any significant problems. Due to the thin frame, I didn't have any problems with vignetting either. The Blue Streak filter effect is great for recreating the Anamorphic Flare effect. In this case, flare from a light source appears as a stretched horizontal line, rather than circular bokeh. With care, this can really add impact to your image and can also be used to give your image a different mood or atmosphere. It's a useful effects filter whether you're shooting, filming, or both. In summary, this is a well-made filter that you can use to add anamorphic flare effects to your photos and/or footage. While it may not quite live up to the standard of far more expensive filters, unless you're a professional filmmaker who needs the absolute best, it should be perfectly good enough for what you need.
