I'm currently using an Olympus OMD EM-5 converted to full spectrum for my infrared photography with an assortment of Zomei filters ranging from 590nm to 950nm.

I used to use an EPL-1 and an EPL-5.

I prefer to use a full spectrum camera for IR rather than having an in built filter as it gives me the option to change filters of different wavelengths and even put the IR cut-off filter back in to re-use it as a regular camera.
