Yah kalo emang udah jatuh cinta jangan kepalang tanggung bro.. oprek aja kamera nya.. (dengan resiko ga bisa ambil gambar normal lagi) karena kalo masih pake filter ga akan leluasa. kemana2 harus bawa tripod, belum lagi harus bongkar pasang filter saat mau ambil fotonya..

Hot mirror itu lapisan diatas sensor yang gunanya melindungi sensor, nah dengan dicopotnya hotmiror kita bisa ambil foto IR seperti halnya ambil foto biasa..

03) Canon 30D (Long exposure time, color not confirmed)
04) Canon 300D(Colour-expect a long exposure time)
05) Canon 350D(Colour-expect a long exposure time)
06) Canon 400D-(Colour-long exposure time)
07) Canon 5D (Colour)
08) Canon A80 (Colour)
09) Canon D60 (Colour-long exposure time)
10) Canon G2 (Colour- No)
11) Canon S1IS (Colour with 2x ELP filters)

16) Fuji s602 (Colour)
17) Fuji S9500

Hotspot:
1. Can Reduce by using larger aperture.
2. Most visible at ~50mm focal length. Can see hexagon shape distinctly. Therefore, avoid 50mm. Long focal length leads to small aperture causing hotspot also
3. CPL, Normal UV Hoya, ND8 all cannot reduce hotspot
4. Lens hood cannot reduce hotspot

Plase note:
Canon cameras = long exposures = many seconds (varies by filter + lens)
Canon EOS 5D requires much less exposure time than EOS 20D



Also, cameras labelled "no-colour" are tested with Hoya R72 filters only,
there are also Edward Long Pass(ELP) filter,
Cokin P007 filter (also a few others) that may be able to produce coloured IR images with these cameras labelled "Colour - no".
