K10D infrared ir conversion

Has anyone converted a K10D to IR?

Who did it? How well does it work? What cutoff wavelength?

I am thinking of converting my K10D. There is a place in San Diego, CA that will do it for $250.

I like IR. It is just too much work with film. I do about four or five exposures for each shot. That provides seven images per roll. I use my Canon 7/7s RFs with the 0.95 lens and Hoya 720 filter. I load two or three bodies in a changing bag and move the lens from camera to camera as the rolls are used. Then there is the developing and scanning. Then there is the unloading in the changing bag. Also carrying two or three Canon 7/7s RF bodies and that huge lens is a pain in the rear!

If you like you can send me that huge lens and it'll lighten your load a little. Hell, I'll take the RF cameras off your hands as well. No? Didn't think so.

I have an IR K20d, that I bought off ebay. The cutoff I believe is 680..

Here are some photos from that camera.

Most of the photos in this gallery were taken with a K10D(IR) with an 830nm filter conversion.

Guys,

Those shots are great!

I've been to Yosemite about 14 times. It is the same yet different. I'm going IR.

Whoo Who! A K10D can be modded!

I'm keeping that Canon 1960s technology. I'll just use it to shoot C41 or Tri-x. I brought it up to make the point that I need to haul around tons of weight, including a very fast heavy lens, three camera bodies to get only one about 18 different images with good exposure and maybe two or three images that I like. An IR modded K10D changes the entire game.

A suggestion: When having a cam modded for IR, replace the internal IR-blocking hot-filter with plain optical glass, NOT with any IR-pass filter. Then buy whatever screw-on filters you want, including an IR-block filter for standard photography. This way, the camera remains a general-purpose device, and any desired part of the spectrum can be sliced and diced for fun and profit.

My experience: I have and use a 5mpx Sony DSC-V1 'Nightshot' P&S (with nice Zeiss optics). 'Nightshot' means that with the flick of a switch, the hot-filter swings out of the way and the V1 sees IR. Using the onboard or an external IR light source, I can shoot in total darkness. And besides the usual B&W and color filters, I have a set of IR-pass filters: 780nm, 900nm, 930nm, and 1000nm, that I can mount on the V1's adapter. Filtered images show quite clearly on the LCD screen. The 1000nm filter usually requires a tripod for daylight shooting, but that may be due to limitations that Sony engineered into the 'Nightshot' system; the others work handheld.

The world looks rather different when filtered through violet-blue, dark red, or IR glass with various wavelength cutoffs. I also have a 5mpx Minolta F300 P&S that's been modded with the hot-filter replaced by a 680nm IR-pass filter. It's easy to use for daylight shooting, but has nothing like the flexibility of the V1 and the range of filters I use there. The V1 is a generalist; the F300 is a specialist.

I can't see thru the 720nm filter with my naked eye. That is why I use an RF camera not an SLR or dSLR. I would assume that I would not be able to see thru it on the K10D also. I don't think my K10D has live view. Is there something I don't understand?

Not really for a K10D, but here is a guide on how to convert a *istD to a dedicated IR camera:

I have two IR P&S cams. The Minolta F300 has been modded, its hotfilter replaced with a 720nm filter. The Sony DSC-V1 has 'NightShot' which snaps the hotfilter out of the optical path; I'll then add a 780, 900, 930 or 1000nm filter. In each case, the LCD screen shows what the sensor sees. If I aim a flashlight into a handheld 1000nm filter, no visible light passes through; but if I mount that filter on the V1 or even hold it in front of the F300, I can see imagery on the LCD screen. I can't say for certain because I haven't worked an IR-built or -modded dSLR, but I assume the same applies: LiveView shows what the sensor sees.

Got my converted K10D back

Got my K10D back from Pro Photo Repair in San Diego a couple of days ago.

I've only tried a couple of test shots in my yard. Everything seems to work as expected. I've got to learn some IR PS manipulations.

I've checked the focus with my FA50/1.4 lens wide open using the 45* test at a couple of feet. It seems right on. I'll try some distance shots too.

This seems like it is going to be fun!
