Digital IR and EF lenses

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.<p>

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?

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.

<p>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. </p>
