The both IR-Shots
were taken with EV-compensation = -0.33.
The C-4040 has a f1.8 lens
and you can hold it very good in your hand, thanks to the
excellent grip. So you could perhaps take some pictures without
tripod if you use ISO200, which are nearly sharp. But I
recommend to use a tripod.

comment: In my
opinion the colors are best if taken with the white balance cloudy, out
of camera its a nice warm picture. If you swap the blue and red
channel and correct the new red channel a bit, you will get an
icy IR-picture. I really like it.
The other way is the manual white balance and then swap red and blue
channel. This also looks nice.
What you don't see: Pictures
are after post processing sometimes noisy, even at ISO100, not dramatic,
but you should have the Neat Image Demo.
Sharpness:
The following pictures are 1:1 crops of the original images. Saved in
Photoshop with quality level '7'.
without IR-Filter:
with Heliopan RG715 (WB
Cloudy):
First you think perhaps the
C-4040 takes soft pictures in normal mode. For better
post-processing the sharpness and the contrast setting in my
camera are at '-3'. The IR-picture contains a lot of detail.
Kudos.
The softness disappear if you take USM in Photoshop, but do this after
post processing and after the noise filter.
