Chinese manufacturer PortKeys has just introduced a new version of its famous HDMI-only compact electronic viewfinder: the PortKeys LEYE II. The LEYE II now features a built-in battery plate. Also, PortKeys has been teasing an SDI version of its viewfinder for quite some time now, which should be released soon. So let’s take a closer look at these!

The PortKeys LEYE electronic viewfinder was first announced back in November 2020. This 4K HDMI-only EVF had a nice and compact form factor (106 x 70 x 78 mm) for a weight of 300g. In addition, the LEYE features a 2.4-inch display with a resolution of 1440 x 900, and can take signals up to 4K at 30 frames per second.

With a very affordable price of $399, this entry-level electronic viewfinder filled a hole in the market. And, if you have a camera without a built-in EVF – like the Canon EOS C70 or Sony FX3 – it could have been the perfect solution.

However, the original PortKeys LEYE had one major drawback: you need to power it externally. For example, suppose you have a small DSLR/mirrorless/cinema camera. In that case, you probably don’t want to unnecessarily rig your camera with V-Mount batteries or a power bank only to feed an EVF.

PortKeys has now released the LEYE II to solve that powering issue, offering a built-in battery plate.

PortKeys LEYE II features

Let’s make it simple here; the PortKeys LEYE II has its predecessor’s same features and specifications. In a nutshell, that includes:

• A 2.4-inch display with a 1440 x 900 resolution. The display has a maximum brightness of 300 nits.
• The loupe of the LEYE II features a +8 to -3 diopters adjustment.

• One full-size HDMI input on the right side that can take signals up to 4K30p.
• DC 7-24V barrel and 5V USB Type-A ports on the device’s right side to power the EVF externally.
• Built-in monitoring tools include: 3D LUT monitoring, Waveform, Luma, Histogram, false color, Zebra, Peaking, Zooming, Audio Meters and so on.

• There are four user-assigneable buttons on top of the LEYE II.
• Two ways to mount the EVF on your camera/rig: a built-in NATO rail and three 1/4″-20 mounting points with ARRI locking pins. All the mounting options are at the bottom of the LEYE II.

You got it; the LEYE II is a pretty decent electronic viewfinder that now features a built-in Canon LP-E6 battery plate at the back of the unit. Unfortunately, there is no indication about the battery life from PortKeys. However, if we do some maths: the LEYE II draws around 3W max, a Canon LP-E6N battery has an 1800 mAh capacity and a 7.2V voltage, so you should get a little over 4 hours of runtime (V x Capacity / P = 7.2 x 1.8 / 3) with one battery, which is fantastic.

LEYE SDI coming soon

PortKeys is also teasing a new version of the LEYE with SDI and HDMI input ports: the LEYE SDI. This version should also have a built-in Canon LP-E6 battery plate.

Also, the barrel connector should be replaced by a 4-pin power input at the back of the unit, next to the SDI input. Talking about the SDI input: the viewfinder should support resolutions up to 1080p60 via the SDI Input.

All the other features and specifications, including the display/monitoring tools/mounting points – and so on – will be identical.

Price and availability

The PortKeys LEYE II is available now for $399/€360, which is the same as the original LEYE it replaces.

The LEYE SDI will retail for $549/€500. It is already listed on our partners’ websites B&H and CVP, so it should be available very soon!
