That certainly sounds true. OTOH eg. I have a cheap video camera module,
which shows infrared visibly on the screen it's connected to (not too
clear, though). And you know Sony's Nightshot -feature on videocameras?
If there are moving parts for it to work, they certainly are really
quiet - I've used the feature couple of times, never heard anything from
the camera.

I dunno, the sensor can pick up the whole visible spectrum and I believe
the software can just pick eg. blue colors from there. Why would IR be
diffent? I'm sure blocking the visible light enhances the quality of
photos, I was thinking aligning the photo.

Yes. Somehow I guided to thinking that having the optical vf doesn't
prevent you having the LCD vf.

Ah yes, I got stuck with aligning the image, not shooting IR. Yes, I'm
fairly certain that blocking the visible light enhances the quality of
IR-photo.

Yes, half-SLR=SL. Seems that the biggest fault is unchangeable optics.
