@[email protected] sensors see IR natively, but it is an interference with visible light, so many cameras add a IR filter to the sensor to cut 9X % of it. Usually you need to remove it to get nice pictures.

I tried IR photography with a Canon 500D and a 5D3 and results were slightly disappointing: very long exposures, blurry images (lenses not always work well with only IR)... Idk how sony's sensors perform on IR, it'll nice to see your results.
