Digital IR and EF lenses

Discussion in 'Canon EOS' started by christian deichert, Oct 23, 2006.

  1. Howdy, folks. I am still looking for input on "hot spots" and near-infrared shooting on unconverted Canon digital SLRs -- that is, using a glass filter such as a Hoya R72 or using a Wratten gel such as an 89B. Here's what I have so far; I am looking for feedback on any other lenses.
    Sample hotspot image:
    Burgruine Landskron, Oppenheim, Rheinland-Pfalz, Germany
    Canon 5D, EF 16-35mm f/2.8L @ 16mm, f/8, 15 seconds, ISO 100

  2. on this page:

    Then this is said about the Canon 10-22mm lens: "no hot-spot, but long wavelengths "smear" at the edges"

    Can anyone comfirm this? Actually I really don't know what he means by this... is the lens blurry at the edges when used in IR?

    Has this lense been working for anyone of you?
  3. The Canon EF 55-200mm f/4.5-5.6 II USM is suitable for IR photography. I just got the Cokin P size IR filter and tried out all of my lenses. I also found that the Tamron 28-75mm 2.8 lens produced a hot spot.

    I have used the 17-40mm f/4L on a Canon 400D using an infrared filter and I got a hot spot in my shots.
