It’s an Olympus E-P1 with a Panasonic 20mm f/1.7 lens.
It’s been converted to full-spectrum by [LifePixel](http://www.lifepixel.com/shop/full-spectrum-camera-conversion/olympus-mirrorless-full-spectrum-conversion) so it has no built-in filter at all, just a piece of glass (Quartz? No idea really.)
The filter I’m holding is some cheap Chinese IR-Pass filter, I believe 720nm, but it’s likely closer to 700nm. It cost me $20 on eBay a while ago, I could never find it again but you’ll find one just like it without a problem.
In sunlight outdoors, with that configuration (with the filter ON) at f/1.7, ISO 200 (base), I generally get around 1/1200 – 1/2000 shutter speeds.
