It is due to internal reflection of light inside a lens. Normal lenses have coated barrels to absorb light, but these coatings don't always work in infrared, causing these problems. Solution:1.Hotspots can often be eliminated by changing the aperture.2.Hotspots occur most often in the same type of shooting angles that cause lens flare. In this case, hotspots can usually be avoided by shooting away from bright sources of light. Exposure:On converted cameras, the exposure meters still work based on visible light. This can occasionally cause some under or over exposure because the visible and infrared light of a scene may not be the same.
