It seems the 5d Mark II is slightly less infrared sensitive than the Mark I, but with suitably long exposures I was still able to get some IR magic. Usually I convert IR to monochrome, but for some reason I was really digging on the hues the filter was producing, so I desaturated them a bit and went with it.
Results are below… note that these pics seem to have a hotspot near the center. I believe this was due to a smudge on the back of the lens. I didn’t notice the hotspot until I downloaded, and went searching for the cause. Nice greasy smudge, near dead center on the rear glass. Can anyone confirm this can cause a hotspot in long exposures?
No idea how I managed that one… I am so careful. Alas. Anyway, I’ll retest, sans-smudge, soon. The trees look excessively fuzzy because it was windy, and these were 6-15 second exposures.
