I hadn't tried an IR filter with the Q yet, so i broke out the Hoya R72 and grabbed a quick shot. This is in full sunlight, Jpeg, Auto ISO, Av Priority, and handheld very casually, with the 01 prime set at F1.9. I got 1/60 at ISO 2500. I was just holding the filter in front of the lens manually. The example posted is only downsized in steps to 800x600 with no other PP. The downsizing alone was enough to pretty much eliminate the noise, which I didn't really find that objectionable at full size, and could have been easily dealt with using Topaz Denoise.
I regularly shoot the Q at up to 3200 with the Q, and I generally shoot jpegs with the camera set to High ISO NR set to "Low" and in camera sharpening set to -4, so I'd have a bit more capability to shoot at lower light levels handheld.This is pretty good, IMO. Another use for the Q. . .Thanks for suggesting it.

Hi Scott, Nice result, though perhaps the ISO might be a bit high to allow for good quality IR photography. Seems the Q's IR sensitivity isn't much different from Pentax's DSLRs. There used to be a time when these little sensors were more IR sensitive. Your result show that IR photography is possible with the Q, though I don't think it justifies the purchase of a separate filter. I'll go for a step-up adapter instead I think.
Tx for taking the trouble testing this!! Esp since you have the Hoya R72 filter, which is exactly the filter I have myself. Local weather is too cloudy here in spite of it being mid summer, and one needs the sun to test IR photography...
