now have 6 lamps with almost identical function and size to this lamp, so I will refer to my experiences with those lamps for comparison. This is a small battery LED (bi-color and fully RGB) with probably the coolest design of all the lights I have, and very simple operating modes. This version of the light is stealth black on black on the back so if someone tries to use it the first time it's hard to read what each button does, but it looks cool and doesn't have the bright white paint if that happens in the picture. I would like the scrolling of the buttons to provide faster action (e.g. it takes a while to scroll to 100% or to 1%) and I feel like the brightness isn't as strong as some of my other similar lamps, but the color temperature measures very accurately and the battery seems to last very well. I have pictured the LEDs at 4000K with 1% brightness to show the number of LEDs and arrangement. I've owned MANY K&F products over the years, including tons of ND and VND filters, tripods, etc., and these lights fit the same high-end build quality as the other K&F products. There are two magenta on the back that you can slightly see through the transparent back. They hold REALLY well on nice flat metal surfaces, but even on a round post they can hold if placed properly. It comes with 1/4 20 screw holes on the top and bottom, and a 1/4 20 cold shoe holder is included. It's worth noting that there is no cold shoe slot built into the lamp itself (for stacking lamps), so you'll need a 1/4 20 to 1/4 20 screw to connect two together. Not a deal breaker, but I often plug my lights in during storage to keep them all together. The overall performance is great, and the build quality and style (if that matters) can't be beat. These are beautiful lights!

This is not my first video light, and I’m sure this is a good video light. Color of RGB can be changed easily and the battery last relatively long, at least 2 hours as I tested. Will buy the second one if needed.

As someone who makes YouTube videos, I’ve accumulated a lot of little RGB lights over the years, but this is by far the coolest, I’ve seen. The overall design is similar to what you’re used to in that it has a CCT mode, RGB mode and some pre-set scene modes, but it’s the overall execution of how these are employed that really sets this little light apart from the others. The style is quirky and cool. It comes in a package that literally looks like a box of tofu. And where others would have boring buttons or sliders, this light uses giant knobs on the side have a fun retro-modern kind of vibe that actually work just as good as they look. From the bottom knob, you can switch it on, turn to CCT mode, RGB mode or the scene modes. The top button allows you to change the intensity of the settings in the various modes, i.e.: brightness, saturation, etc. And of course there’s a magnetic back and not one, but two tripod mounts - one on the bottom and one on the top. This is a really well-designed little RGB light that stands out in a crowded market place of similar lights. This light both looks great and works great - definitely would recommend.

This door is fairly easy to install and works great with the timer. I have it in a place where it closed too early with the light sensor. If you use this option, make sure the sensor is in a location that receives full light. I set it to open at 7:30 in the morning and close at 7:45. It took about a week, but now all my chickens go in before the door closes.

I've been using this for several months. I use the timer over the light sensor. The light sensor is NOT sensitive enough to open and close with the sun. But it works fine on a timer. I'd prefer light sensitive so I wouldn't have to adjust it as the days shorten.

I created a custom wood frame to attach the door to, my preference . Remote works from a long distance which I appreciate.

Like most other reviewers, I thought long and hard about buying this lens. For me it was about the fact that I had never owned a prime lens before and that I worried about being limited to the one prime lens... Would I find myself wanting to constantly pull one of my zooms out of my pocket to take the shot? Now after owning this lens for a few months I can say the concerns are gone and I find that this lens is more attached to my Canon 50D than any other lens I have owned. This lens is just amazing! I was also concerned about the "crop factor" of APC sensor size... this has been talked about a lot in relation to lens focal length. I just don't understand the problem with this lens. The quality of the shots you can capture far outweigh the fact that an APC sensor size digital camera is not a "true 50mm". I guess I can understand some people's argument that this isn't a good "walk-around" lens for indoor use (because it's basically an 80mm lens on a camera the size of an APC sensor), but all you have to do is step back from your subject a bit and you'll be fine. Plus, its low-light capabilities far exceed any other similar lens, which is a big plus indoors. A good photographer wants to “fill the frame” anyway. I loved this lens indoors. The depth of field this lens can achieve really opens up the creative possibilities. However, I've found that the images lose a bit of sharpness when wide open at f1.4, so I've resorted to shooting at f2.0 when I want to open them. I swear you could focus this lens on a pinhead and I'm amazed at the bokeh (background blur) produced. So far the only negative I have is when I switched the lens to manual focus... I had a hard time getting it to focus properly. But to be honest, that might just be me and my skills at the moment. This lens is truly a must-have for any photographer of any skill level. Your creativity will increase and your shots will amaze... I promise!

These are great low light filters. Due to the 1" sensor on the Air 2s, darker filters are required for bright/very bright days.
I already owned a filter set of the same brand for Mini 2, I bought it for Air 2s. What can one say about quality at the right price? K&F Concept is on the safe side.

Very nice and active
