I can confirm this behaviour for my IR-modified Exilim. not always but most of the time (I think the Contrast-detection autofocus doesnt work well with the slightly "blurry" IR)I wonder if the autofocus is a bit off with the IR
720nm. I need to get a higher wavelength filter.Nice shots! Especially the panorama. What wavelength filter?
