[Aluminum] This slider is perfect for my videography job. Very light weight, easy to use. Quite and smooth when moving, and I ski like you could use the app on your phone to control it.

[Carbon Fiber] The carbon fiber construction makes this a great slider for travel. It is light weight and durable. Smooth action for short runs.

[1/4"-20 Male] Yes, it's wireless. Bluetooth controller. Haven't tried to figure out the range yet. But the good news is that you can walk away with your iphone after you set it in-motion, and it keeps going. I'm talking about time lapse. I didn't want to leave my phone next to the slider for a 4 hour session. Didn't need to. Once started, it kept going without the phone nearby. However, the software will not be happy if you don't respond to the notice that it's lost the Bluetooth connection. I had to uninstall and reinstall the software after I didn't respond to the notice that the Bluetooth connection had been broken. Just let it know that you are fine with losing the Bluetooth connection and you'll be good to go next time you set it up. That said, installing the software on my iphone was easy.

I'm using the slider with a Sony A9 that has its own timelapse feature so I haven't tried connecting the camera to the slider motor. But if your camera doesn't have timelapse, you can connect a cable between the slider motor and the camera. B&H sells the standard model of this slider that comes with a Canon shutter cable. If you buy from other sources, Konova will let you pick a different shutter cable. Not really a problem. I ordered two Vello shutter cables from B&H for my other camera models...and they were less than $10 each.

I'm using this slider with two tripods. It takes a bit of doing to get the tripods just right in terms of distance and height as I'm outside on uneven ground. But I think the results are worth the effort. I'm using an NP-F970 battery clone for power and it's fine so far. Despite being out in 20 deg F temps, it runs the slider for hours without issue. And I haven't noticed any jitters or noise from the motor. It all seems very smooth and quiet so far. I'm pleased with this slider and would recommend it.

[1/4"-20 Male] I needed an inexpensive slider for a volunteer job I'm doing currently. This is my first slider and most likely my last. Even though it's only 32 of travel on camera it looks much more. Easy to set up and use. smooth operation mounted on a single tripod with my GH6 and 25mm lens. Any thing heavier you might want to support it on both sides. works great horizontally and every angle up to 90 degrees.

[1/4"-20 Male] I have been using this slider for over a year now and I really like it. It replaced a manual slider by iShark that I had for several years. It is simple to operate, and I've found it to be extremely quiet. (When I first purchased it, it had a squeak... but after a very short while that went away as the unit got broke-in.) It doesn't have all of the bells & whistles of more expensive units, but for the price it's definitely worth it. I use it with a Sony A7iii and Sony A7IV - in mostly tracking mode - during interviews. One thing I was worried about was how quick the app that controls it would connect with my iPhone - and it is almost instant - very fast - so no issues there. Works great!

[Yes] Slider works as expected, I had a few questions and customer service reply was very fast and helpful, the bluetooth connection works without problems and it is stable.

[1/4"-20 Male] the K5-120 slider rocks. it's solid, very little flex. very happy

[1/4"-20 Male] Silent motor wich is working not only with NP-F type batteries, but also with power banks. Very easy to use app to work with.

[7.38 lb] it has been an amazing slider and will recommend it to anyone in the professional videography working world. its light weight easy to assemble and the carrying case makes it compact for any type of storage!

[Aluminum] Love this slider. It's light weight, quiet, and super easy to use. My set up is throwing this on a Magnus tripod and using supports to attach to the tripod (sold separately). We shoot using Blackmagic Pocket Cinema Camera Pros. It's easy to attach to the slider. My favorite part is the app control. Just lock in the camera directions and hit the left and right arrows. Easy as that. The 47 works really well with our studio. Lots of room to pan - especially if you crank this down to a nice slow motion speed. Seriously surprised at the quality for the price. Would highly recommend. Also - fwiw customer service is really speedy on email. I had a shipping issue from a third party seller and they're helping me out with it.
