CANNON 20D 红外改机教程
You will need these tools & supplies to follow the 20D infrared conversion tutorial:
- Our custom glass infrared filter to replace the hotmirror
- Soldering iron and desoldering wick or desoldering gun
- Black silicone adhesive /w syringe type dispenser
- Small philips type screwdriver
- Tweezers
- Canned air
- Lens cleaning solution & tissue
- Grounding strap /w current limit resistor
If you prefer not to risk damage to your camera, have us convert it to infrared for you. It would be best to perform the conversion in a well lit area that is as clean and dust free as possible. Wearing a grounding strap will minimize the chance of zapping your camera with static and most likely rendering it dead.

After adhesive is fully cured clean the ir filter with lens cleaner and tissue, blow off with canned air and reassemble everything by following the instructions backwards. Set a custom white balance per our instructions page and take some test shots to make sure there is no dust trapped between the sensor and infrared filter. If you find dust and find it objectionable disassemble the camera again, blow off the sensor with canned air (make sure only air and no liquid is coming out by purging and holding it upright) and re cleaning the infrared filter.
