In this article I present some new infrared images, mostly taken with an infrared converted Canon 350D. For these shots I used a lens that others have warned not to use for infrared photography.
This is the one shot here not taken with my converted 350D. It was shot with a Canon 400D, the supposedly non-IR compatible EF 24-85 f3.5-4.5 USM lens and a Hoya R71 filter. Exposure was 30 seconds at f5.6 and 100ISO. Focal length was 85mm.
Also with the 24-85mm lens, but now on my converted 350D. Focal Length was 30mm, 1/320 second at f8 and 100ISO.
Same lens and camera, 1/200 second at f8, 85mm focal length.
Same lens at 24mm, 1/160 second at f8, 100ISO.
85mm, 1/200 second at f8
85mm, 1/400 second at f8
I shot a full sequence of shots with the EF 24-85mm f3.5-4.5 USM lens, at all apertures and at 24mm, 50mm and 85mm and found no central hotspot.
