Canon 40D 10.1 MegaPixel Professional Infrared-Enabled Camera Models: XNiteCanon40D : UV + Visible + IR XNiteCanon40DIR : Dedicated IR-Only. 715nm or 830nm.
The Canon 40D is a professional digital SLR camera. Because of the nature of the IR enabling modification, we do not recommend this camera to anyone who does not fully understand the implications of the modification. We can modify this camera to be UV+IR+Visible or IR-Only. An IR+Visible camera will see both Infrared and Visible light after modification. IR Only cameras have the option of being setup with an internal 715nm or 830nm filter. An IR-Only 715nm camera will only see IR from 715nm through 1200nm. The IR-Only camera has an internal 715nm IR filter with an antiflection coating. The 715nm filter performs similarly to the Hoya RM72 and Wratten 89B. An IR-Only 830nm (87C equivalent) camera will see IR from 830nm through 1200nm. Because the 830nm sees less light, you will lose about 2 F-Stops. You will gain a higher resolution picture because the RGB channels will be more closely balanced. Because camea sensors have 1 red, 1 blue and 2 green pixels for every 4 pixels, and because the red channel is the most open to IR, with a 715nm filter, about 65% of the image comes though the red pixels. Thus, 65% of the data is coming in on 25% of the pixels. With an 830nm filter, the channels are much better balanced because of the way the mosaic color dyes on the sensor open up in IR. When the channels are better balanced, the camera can resolve better.
Drawbacks on UV+IR+Visible Using digital SLR camera means that you look through the lens. This is great when you can physically see through the lens, but with a true infrared filter on the camera, you will not be able to see anything! After taking the picture, you can review the shot on the LCD display on the back of the camera. However, the camera image sensor (the CCD) is hidden behind the camera's shutter until you take a picture. Therefore, you cannot preview an infrared picture prior to taking the shot. Unlike consumer cameras like the other Sony digital infrared enabled cameras which we sell, the Canon 30D meters light through a separate light sensor. The typical consumer cameras use the camera's CCD to set exposure. Since the Canon camera has a separate metering circuit, the camera does not correctly automatically set exposure. The user must manually set the Exposure Compensation (EC) function. The amount of correction will vary depending on the ambient infrared light. We may find a fix for this in the future. This modified camera sees infrared and visible light simultaneously. For normal photography, you will need to use an IR blocking filter like our XNiteCC1. You will need an XNiteCC1 filter for each lens size you plan to use for normal photography. Modification will void your warranty. Conclusion UV+IR+Visible enabled digital SLR camera is only good for somebody who really needs a serious infrared capable digital camera and wants to take visible pictures as well If you will only be using the camera for infrared, we recommend the IR-Only version because you will be able to see through the lens, autofocus and shoot in automatic modes as long as you dial in the exposure compensation needed beforehand. If you are a casual user, you are much better suited getting a camera like the Sony DSC-F828 which doesn't have the exposure compensation issue and only uses one filter size. If you don't understand the explanation above, do not buy this camera. We can modify your Canon 40D for a $450 fee + return shipping & handling ($20 for UPS ground insured within continental USA).
