Infra red filter?

All DSLRs have built in IR-cut filters... some are more aggressive than others
If you want an IR camera, there's a US company that can "hack" your camera and remove the IR-cut filter completely. Pete Bargh did an article on ephotozine.com - he had his *ist-D modified for IR-only photography. Great results (if expensive)!

Simple answer, they both do, but the one in the K200D filters out more of the IR end of the spectrum.
I think your K110D is a 6Mp camera, the same as the *istD, and the K200D is 10Mp, which is the same as the K10D.
For that reason, I have kept my *istD for the odd IR excursion. It's also possible to have this filter replaced entirely with plain glass making it even better for IR photography, and near useless for anything else.
EDIT: Matt can type faster than I can .

OK, so ALL DSLRs have a built in filter
What about 'pocket' cameras, only my new Panasonic Lumix shows the IR brightly, as does my old Sony DSC-U20. Does this mean the filter type is the same as the K110d? :
I'm only interested out of curiosity!
Just found my daughter's Nikon Coolpix E5600 sees the IR as well.

I don't know the technical reasons for your experience, but what I do know is that Infrared light is not normally visible to the human eye. Our visible light falls between the 300Nm and 750Nm wavelengths and IR occurs between 750Nm and 1mm.OK, so ALL DSLRs have a built in filter

Your K200D therefore is showing a closer approximation to human vision than your other cameras which must be recording the IR portion of what they 'see' as visible light.

All sensors are very sensitive to IR light, so it's usually filtered out to a greater or lesser degree. The *istD series and it seems the other 6MP variants are quite good for IR - use an R72 filter over the lens for the best result.
The K10D was poor for IR and we can see why.
Some earlier Kodak compacts are highly sought after as they have no blocking filter. Don't ask me which ones though...

There's a company in Norfolk that does this too (might even have been there that Peter sent his camera). Costs about £200, and they offer different levels of IR effect, depending on what sort of filter they use to replace the stock one.All DSLRs have built in IR-cut filters... some are more aggressive than others

To quote John;
Do the other cameras I have share a common make sensor, perhaps Sony?
Which would explain why they see more IR.

Here is an example taken with*istD + Hoya R72 filter with an old Hanimex 28mm lens.

Thanks for the info.
So let me get this straight, my K110d and a R72 filter should allow me to play in the IR, getting shots like DOIK's.
When the Xmas rush is out of the way I'm going to Play.

Correct.my K110d and a R72 filter should allow me to play in the IR
Your K200D might produce similar results but would require much longer exposure times.
By replacing the sensor's filter with plain glass, handheld IR is possible as the exposure times are dramatically shortened.

If you wind the Iso setting up to 1600 or 3200 you can hand hold but you cannot see what you are taking as the filter is opaque. This is how I took my first shots, some turned out ok.Using a tripod you have to compose without the filter then take the shot, or use the display to check the composition.Quote:

That Company in Norfolk is near here. I can check them out for you if you're considering using them. Alternatively just do that remote control test and see if you'll get the results you're after

Out of interest I checked using my K200D and got this
As the IR transmitter in the control isn't visible with the K200D does this mean the camera has a built in IR filter?
