The GoPro Mission 1 Pro ILS is the smallest mirrorless camera yet – but it’s so small, it can’t use lenses heavier than this without help

GoPro’s first mirrorless camera is so small that the Mission 1 Pro ILS looks closer to an action camera than a mirrorless camera. The GoPro Mission 1 Pro ILS’s size creates wider flexibility in getting shots in tight perspectives and creating small mounted rigs. But the small design isn’t without its downsides: GoPro recommends using an added support for Micro Four Thirds lenses that weigh more than 250g.

The GoPro Mission 1 Pro ILS uses a Micro Four Thirds mount, which opens the action camera giant’s first mirrorless to hundreds of different lenses. However, the camera body doesn’t have any electronic form of communication with the lens, which means electronically driven “focus by wire” lenses aren’t supported.

In focus-by-wire optics, the focus isn’t physically adjusted from the turn of the focus ring but is instead adjusted electronically. This electronic design requires communicating with the camera body, and the Mission 1 Pro ILS doesn’t have any electronic contacts to communicate with the lens.

That takes MFT lenses like those from OM System and Panasonic off the table, as these lenses require communication with the camera to work. Besides disappointing creators who already own a stash of lenses from those brands, the incompatibility with OM System takes a number of weather-sealed lenses off the table.

While I was disappointed that I couldn’t mount my OM System 150-600mm lens on the Mission 1 Pro ILS – because how cool would a 1,800mm equivalent be! – the ILS will also need help supporting heavier lenses.

When I started testing the ILS, GoPro recommended that I use a lens support system for any optics over 250g, though the company noted that lenses with a built-in tripod collar could be supported by using the collar on a tripod.

Using a lens support system is going to increase both the size of the camera and the cost. SmallRig makes a universal lens support that sells for about $22, for example, but it requires rods and a baseplate. Adding the SmallRig 15mm baseplate and rods would be around $125 (about £91 / AU$175 / CA$173) worth of accessories to help support larger lenses.

Lenses 250g and under don’t need any additional support – and there are quite a few lenses that GoPro recommends from the Laowa 7.5mm f/2.0 Dreamer that I used with the new ILS to optics from TTArtisan, Rokinon, Meike, Viltrox and several others that fit both the mechanical focus and weight requirements.

One more thing to note? When swapping lenses, you have to go into the camera menu and select the correct lens, or HyperSmooth won’t work properly.

There are compromises that had to be made in order to create a mirrorless that small, and potential GoPro mirrorless buyers need to be aware of them before committing to the tiny 8K camera from the well-known action camera brand.
