My journey to explore infrared photography began with the Fuji X100F digital camera. Fuji did a great job developing and building this camera and, it's got a solid reputation and following. With 24 megapixels it's plenty of resolution and produces excellent images. The X100F is an order camera and I didn't need the film simulations so the F model works fine.  I chose mine from Lifelpixel.com used. Good service and advise and it's been a reliable camera. I chose full spectrum modification as I have many filters. 

Things I believe are important to Infrared are:

Ability to produce RAW Files. I only photograph in RAW files in Infrared. 

Live View with Focus Peaking for accurate focusing. The Electronic Viewfinder is an added bonus however I mostly use the love view. 

Ability to make a custom White Balance for the LiveView screen. This allows me to get a better idea of what the image will look like. 

Live View Histogram makes for easier exposure settings. 

Reasonable Noise.

Compact Size. 

Camera others are using with Infrared.
