After reading Big Ga's thread on comparing IR sensitivity of various µ4/3 bodies, it struck me odd that the E-M5 would be so much more sensitive to IR than the rest. So I decided to try my E-M5 with the Hoya R72 filter attached to the 14-45 zoom. I let the Auto ISO max out at 3200. This gave me a hand holdable shutter speed of 1/13.

OOC image. Only resampled and sharpened.

After channel mixing and custom WB via eye dropper.

Much better (and easier) than my previous attempts with the E-1

Now I'm wondering if I still need to send my recently acquired G3 for a Full Spectrum conversion.

Stick with the E-M5 for the moment.  If you want a better image to work with w/o resorting to monopod or tripod, and it's more than a passing allure, you'd want a dedicated sensor (and you'll know soon enough).

Even with a converted E-PL2 at ISO 200 noise (especially blue sky) has to be dealt with, or embraced creatively in tune with masked sharpening.   Get more acquainted, see how it goes.   And for the glow, I find in LR tuning in a negative Clarity can help impart that IR characteristic.  IIRC that characteristic doesn't occur with sensors like it does with film.

I don't have any OOC exposures posted, just what I could fashion from RAW IR
