K&F Concept Monitor Mount Review: A Cheaper SmallRig Alternative

This is the English edition of a review from my Japanese YouTube channel, iestaLife. I review gadgets from my home studio in Japan, so product links go to Amazon Japan.

Quick take

The K&F Concept monitor mount does almost everything my SmallRig mount does, adds a hand-tightened knob for the tilt angle, and cost 2,657 yen against 4,299 yen for the SmallRig model with a knob. Unless you use it on professional shoots every day, the cheaper one is enough.

What I tested

  • K&F Concept monitor mount (black with orange accents)
  • My older SmallRig monitor mount, which needs a hex key to tighten
  • A Sony mirrorless camera, with an iPhone 17 Pro Max as the monitor
  • A MagSafe stand with a 1/4-inch thread to hold the iPhone

The SmallRig weight and photo are of my older model. The 4,299 yen price is for its newer version with a knob.

What I found

  • The knob matters: with my old mount, a loose setting made the monitor wobble, so I kept it fully tightened and could not change the angle. With the K&F knob I can tilt the screen when shooting from above or when there is glare, then lock it again by hand.
  • Size and weight: the SmallRig is slightly slimmer and about 10 g lighter. The knob sticks out a little, but it never bothered me.
  • Out of the box: it comes with a hex key and a single sheet of paper. The head was slightly crooked on arrival, and the hex key fixed it.

Using an iPhone as the camera monitor

What I really wanted was to use my iPhone as an external monitor. Sony’s Creators’ App can now do this over a wired USB-C connection. Over wireless I used to see lag when I moved my hand in front of the lens; wired, I could not see any. The iPhone screen is larger and brighter than the camera’s own display, and it needs no separate power like a dedicated field monitor.

Who it is for

  • Hobby and YouTube shooters who want an adjustable mount without paying for a big brand.
  • Sony users who like matching the orange accents.
  • If you want the slimmest, lightest option from an established rig maker, the SmallRig is still a good choice.

Watch the video

The video is in Japanese. The iPhone monitor demo starts at about 5:40.

Limitations

I had used the mount only for a short time when I recorded this, so I cannot comment on long-term durability. Prices were Amazon Japan prices at the time of recording.
