    Hi,
    I have finally removed the ICF from my OM-D to use for shooting UV, as my newly acquired E-P5 has now replaced it as my main visible-light camera.

    Here are some Rudbeckia flowers taken today. I used the ICF I had removed from the OM-D as the UV/IR cut filter, mounted in front of the lens. That way I can use auto whitebalance for visible images.

    Visible:
    9554621281_b8e4852a28_b_d.

    UV:
    9557405150_ace51d1b96_b_d.

    Vis:
    9554625563_9a907e5902_b_d.

    UV:
    9557417526_91ceb3c523_b_d.

    The advantages of the OM-D for full-spectrum are:
    1) with the grip, it will feel more balanced with larger lenses such as the Coastal Optics 60mm f4 or the UV Nikkor 105mm.
    2) its 5-axis IBIS will allow for the use of slower shutter speeds which are often required for shooting UV. I can consistently get 3-stops of IS with the lens I normally use for UV. The IBIS also helps when doing manual focusing for UV, as the image is stabilised in magnified view.
    3) built-in EVF is very helpful for focusing in UV (especially when shooting out in the sun), and you can still mount a flash for UV lighting.

    Disadvantages:
    1) cannot programme Myset to the mode dial like the E-PL5/E-P5
    2) no focus peaking like E-P5

    Sadly I do not think that the camera-modding companies are able/willing to mod this professionally, as it is deemed too risky due to those strong magnets of the IBIS (I had asked Lifepixel about modding this camera about a year ago and that was their explanation then). This may be the only full-spectrum OM-D out there.

    Ok - my mind went "wait, what??" as soon as I hit "ICF" -- but very cool pictures nonetheless. Not really into IR photography, but I enjoy the few I've seen here in the forums.

    Intriguing!
    Show me how you do this!
    Are you restricted to lenses with a small-diameter front lens?

    This is how I did it. I drilled a rectangular hole into a M39 body cap and epoxied the ICF to this; this is stepped up to 42mm. It is then mounted into a 49-42mm step down ring, as I have standardised all my filters to this size to fit on my Xume magnetic adapters. But I'm sure it can be made to any other size.

    There is some corner vignetting with 35mm focal length lens, which disappears by f5.6-8; there is none with my 60mm UV lens even at max aperture of f4. I've not used it for wider-angled lenses.

    Thanks, Klaus.

    These are UV images taken handheld with the OM-D using my 60mm f4 UV lens and Baader U filter, lighting from a Quantum T5DR mounted on top of the OM-D (a little top heavy though).

    Today, I tried to push the limits of the OM-D in shooting UV, to see how well I can shoot handheld with a little assistance. I did get a little extra support from a 'neck tripod/monopod'.

    I managed this shot at 1/4 secs ISO 3200 f5.6, using my 60mm UV lens - effectively 5-stops of IS with the IBIS. It was rather windy, so could not get any good images at slower shutter speeds. ISO 3200 is probably the limit for shooting in UV, as ISO 6400 is too grainy.

    Looks rather good to me. Great achievement that IBIS!

    Thanks. But I still prefer to use a Xenon flash to light the subject as I can use lower ISO and smaller aperture. This of a different Rudbeckia, shot at f8 ISO 800 with Quantum T5DR at maximum power.

    This is what the OM-D sensor looks like without ICF.

    Turned out very well Boon! How did you remove the ICF - from the front?

    Yes from the front - it is not possible to mod the OM-D the traditional way as it has strong magnets for the IBIS, which makes it too risky to mod. And I managed to preserve the ICF in the modding process to use as UV/IR cut filter to allow for visible light imaging using auto whitebalance.

    really interesting indeed, I like that fact that you had the mind to keep it and use it. the effect on the colors is something you either love or hate.its looks like some one charcoaled the flower.

    Does the mod result in loss of infinity focus?

    Yes it does as I did not replace this with a Quartz window, although I am looking into this. But there are certain M43 lenses which still infinity focus, such as the Olympus 14-42mm ii, and the longer focal length lenses such as Panasonic 100-300mm, Olympus 75/1.8. Definitely not with the Panasonic 14/2.5, 25/1.4 or 12-35/2.8.
