Has anyone tried shooting infrared with RD-1? How is its sensor's IR response (through an R-72 filter that is)? I've been shooting IR with the closest thing to a digital RF I ever had, the Canon G3. Sensors are supposed to lose a lot of their IR sensitivities as their generations progress. The earlier Canon G-2, D30, and even my "old" Fuji finepix S2 dslr could shoot IR easily. That meant being able to shoot at 1/10 sec in bright sunlight at the gain setting of ISO 200-400. In contrast, my 300D and 350 with latter generation sensors are almost blind to IR. The 300D would only produce a barely registered image through an IR filter with a 5 sec exposure in bright sunlight at ISO 800 setting! The Canon G3 at least allowed me to view the scene through its optical finder- the R72 filter is almost opaque.
RF had always been IR film-friendly. Does this hold true with the digi-RF?

hello,
yes, the R-D1 is perfect for near infrared through a R 72 filter. The problem is, that the red channel (which is fastest for NIR) has a rather low resolution (problem of bayer filter, plus diffraction). But even the green channel is enough NIR sensitive for use with a R 72, so you can get IR B&W photos with a better resolution using the green channel and a tripod.

I've posted a couple of examples of IR on the R-D1 here.
Note that, though you get the best results using RAW and then choosing the green channel, you can good jpgs in camera by using the green filter option in b/w mode.
This mode is also helpful (even if you shoot RAW) for judging the exposure on the LCD, as in normal mode the red channel blows away all the tones, making the exposure impossible to judge.
Hope this helps
