Hire Sony FX3 - Full Frame Modified Camera for Wildlife Production
Hire Sony FX3

Modified Sony FX3

Hire the Sony FX3. This model is a full frame camera for outdoors and wildlife production. Sharing the same sensor as the legendary A7Siii, the Sony FX3 is a small yet powerful cinema camera that boasts incredible low light performance. Ours has been modified for full spectrum shooting, permitting ultraviolet and infrared night vision filming.

Key features



Yes, the camera operates exactly the same as an unmodified Sony FX3. In addition to the UV and IR spectrums, it still sees visible light and using the included IR cut filter, it can still take regular colour video.

The camera may however struggle to accurately autofocus in the infrared spectrum as the light focuses at a different point than in the visible spectrum. Autofocus will still work with regular light.


The short answer is yes.

The amount of IR light in the scene dictates the extremity of the colour cast. Shooting with any sunlight in the scene (even indirectly, such as through a window out of shot) will result in a heavy red colour cast. Many artificial light sources however do not produce much (if any) IR light: an interior scene shot at night may appear completely normal. That said, it is important to keep an eye on any black materials in particular when shooting without filtration; they may take on a slightly purple hue.

An IR cut filter is included and would be necessary to use in order to ensure colours are represented accurately.


Unmodified cameras can only see what our eyes see – from about 400 to 700 nanometres.

The full spectrum modification expands the visible range in both directions. The camera is now sensitive to light from around 250nm in the ultraviolet spectrum, all the way to 1000nm and above in the infrared spectrum.


The infrared spectrum (from around 700nm and above) is invisible to human and animal eyes. The camera however, can see light in this spectrum up to and over 1000nm.

Using infrared lighting, you can illuminate the area or light the scene exactly as you would with regular lights, except this is only visible to the camera. This is how CCTV works at night.


No, not at this time. There are so many different kinds of infrared lights that it isn’t practical for us to cater to every requirement.

IR light sources are readily available online from Amazon, in addition to more specialist suppliers offering an even greater selection of products.

850nm and 940nm wavelength IR lights are the most common and these are what we would recommend to use with this camera.


Yes, we include two filters – an IR cut and an IR pass. Both are 82mm screw-in type, along with step up rings allowing you to use any lens with a 52mm thread or greater.

The IR cut filter only allows visible light through. With this filter you can use the camera as if it were unmodified, producing realistic and accurate colours.

The IR pass filter blocks all light below 715nm and is opaque to our eyes – meaning only infrared light is let through to the camera. You can use this for false colour. For IR night vision filming, using the IR pass filter is optional and not strictly necessary, depending on the desired effect.

These two filters are suitable for most needs. Other filters that cut or pass at different wavelengths do exist and offer different creative effects – though these are predominantly for photography and not as suitable for filming due to longer exposures becoming necessary. As with IR lighting however, it isn’t practical for us to stock every type.

I've seen some crazy coloured infrared imagery. Can I do that?

Yes! The crazy coloured infrared imagery is called false colour. You’ll likely want to filter out visible light using the included IR pass filter for maximum effect.

These images however are heavily processed and do not come out of camera looking like that. Heavy curves may need to be applied in grading your video for an acceptable level of contrast, plus manipulation of the colour channels is commonplace. Typically ‘channel swapping’ is employed on the red and blue channels to achieve the milky, blue and pink pastel tones you’ve seen.


This FX3 sports a native Sony E mount, plus we supply either a Metabones EF or PL mount when your hire Sony FX3 from Wild Films. You can therefore mount any of your existing E, EF or PL lenses on the camera and use them as normal for regular (visible light) shooting.

However, for infrared shooting, some lenses perform better than others – and not necessarily the ones you might expect. Some of the best lenses may not work very well in infrared, and vice versa. The most common problem is the introduction of hotspots – a bright area in the centre of the image. This will vary with the lens, zoom position or even focus distance. Generally they’re more evident at deeper (smaller) apertures and less apparent at wider stops. They’re also not necessarily consistent across the same set, series or era of lenses – so one good lens doesn’t mean all of its siblings will work well too.

The best way to work see what works is to test all of your lenses prior to a shoot and see what you deem as acceptable. That said, a number of lists already exist online that detail which lenses work better or worse, a good example can be found here.
