I rented a modified 5DII camera for a week from Lens Rentals. I wanted to offer a brief synopsis of my experience and an image or two. I was pleased that the camera behaves identically to a normal 5DII except for the sensor cleaning hardware which has been removed. The first thing I did was disable auto sensor cleaning in each of the various settings C1-C3 and automatic modes. This bypasses the error concerning the lack of sensor hardware.

In terms of operation this camera works best with normal light levels. It does work at low light but the results are no where near as exciting as normal light levels. The processing was really easy. I basically took raw images and converted them to monochrome in DPP. Fixed the levels and voila white foliage. This camera has been converted to 715nm which results in sharper images according to those who would know. I shot the entire week using a Zeiss 50/1.7 which worked great. I also used a Leica 100mm macro as well though the Zeiss really produces some nice contrast and the 100mm was used exclusively at a small safari park so the comparison isn't precise. I found that I could drive the Columbia River Gorge in late afternoon light and shoot right through my windshield at 55MPH with the 50 on f/8 ISO 200 with excellent results. Not a recommended practice but I made it work and with reasonable safety for all parties.

Here is an image from a conference I attended a few weeks ago at a ranch near Mt Adams. Early morning.

I'm sorry, i'm not really familiar with Infrared or whatnot; can you elaborate to me, Why? What is the purpose of modifying a camera specifically for 'Infrared'?

Not having a dig, I just don't know! :)

IR shots are sometime very eerie but also very cool. Sure you can add filters to your lenses, but that causes grief with focusing and long shutter speeds, etc. Modifying the glass in front of the filter to be an IR filter allows the camera to work in all normal regards (you can see through the viewfinder with no issues, AF works fine, etc) so it behaves like normal, but your shots then come out as IR. It usually means the camera cannot be utilized for any other kind of photography though.

one of the main reasons I'm into it is because different things reflect IR light much differently to normal spectrum light, you can get very depth-seperated subjects (if that makes any sense)
Trees/foliage etc reflect very well whereas harder substance reflect less so.

Post processing can be either for a black&white effect or faux-colour where red & blue channels are swapped, and you end up with a coloured picture.

to give you an idea, some of my recent IR shots are posted here (external link)

Jetcode - that cloud looks surreal! very nice...

I had my old 10D converted to deep B&W mostly because I prefer the look of the black & white infrared photos. Still, often wish I'd not converted to B&W so I could have a choice but what I get I really like just the same.

Shortly, I'm planning on sending my 5D off to be converted to Super Color Infrared to give me more selection and those can be converted to B&W ... or as I read, just set the camera to B&W mode.

Love shooting IR!!! :D

From my old 10D ...

Another reason to shoot IR,..
They LOVE Mid day harsh contrasty sunlight!
When normal smart photographers are packing it in for siesta, since the lighting is so damn bad, you can instead pull out your IR converted DSLR and shoot all you want.
And make some great pictures while you do!

Had my 10D converted at www.lifepixel.com (external link)

They now offer Super Color IR so that's what I will have the 5D converted to.

I think you get a really great infrared from the 10D. I used a photo filter (CS5) to warm the tone a bit though that is one choice and not necessarily the last choice. Did you do any additional filter processing on your raw images?

I am also planning to get an IR filter... but decided to get the Sigma 12-24mm as my UWA.. and can't fit an IR filter in this lens so have to wait for a while until I get the Nikkor 24-70mm before I buy the IR filter.

The red channel is where the information is at 715nm. There is no yellow as there is little blue or green at 715nm.

Are you shooting everything stopped down? Ever try IR photography with your lenses wide open? I'm wondering about the focus shift of IR light.
