Well, for my IR's, most are with my large format. The little guy (Sigma SD14) isn't really the best for IR. The sensor is good for IR but the lenses are not. The have hotspots and color shifts, plus the coatings are not designed for IR, nor the element groups, so you don't get a totally tack sharp images.
The large format I use is a custom homemade 544 megapixel scanning back digital. [link] The sensor size is 8in x 12in, but it is monochrome, so I have to use filters to get color. Most of the time I don't shoot standard color, I shoot panchromatic.
UV -> Blue [link]
Vis -> Green
IR -> Red [link]

for example [link] [link] and [link]
I definitely like using the large format because the files are crazy sharp and huge, but you definitely can't shoot sports with it. I'm currently in the process of starting a company to custom build them for customers, seeing as no one else makes anything like that for under eleventy billion dollars. The sensor sizes available will be 8x10 and 11x17. Website will be up in a few months, otherwise I would send it.
The basic design is [link] except that they are made out of aluminum and there are nice threaded slides with digital readouts for focal lengths. I'm trying to keep the price under ten grand so it doesn't price out serious landscape/portrait photographers that can't afford a Hasselblad or phase one. Total camera system excluding lenses and a tripod.
Most of the shots that I take are done with my first model. Horrible design and internal mechanics, but it still works, which is amazing for how much abuse I put it through. [link]
The filters I use are all in this box [link] plus a few other 82mm circulars.
List includes
1 stop ND
2 stop ND
4 stop ND
>550nm cutoff (yellow)
>650nm cutoff (red)
>720nm cutoff (IR)
>760nm cutoff (IR)
>850nm cutoff (IR)
>950nm cutoff (IR)
<650nm cutoff (Vis and UV)
320-380nm (UV)
2 polarizers
Ground glass to put in front of lenses and get vignette images, so I can remove lens vignetting as well as color ghosting in my little camera.

I see that you live in Utah. I've taken many trips there. Beautiful desert landscapes and nice semi-arid climate.

What is in your camera arsenal?
