Canon 40D DIY infrared full spectrum conversion time-lapse 1080p 

I totally agree, this was done before mirrorless cameras was available. I have since converted an eos m camera as well that I use as main IR-camera, with lens adapter to still be able use the great EF 17-40 for IR.

You would need to calculate the correct thickness for a direct replacement without washers. Was so long ago that I cant remember exactlty what it should be, but I think 2mm glass gives a negative distance and that 3mm was the first standard thickness glass that gave a positive distance where washers could be added to compensat. Edit: If you have a modern mirrorless dslr that you want to convert, its better to purchase a proper ir-pass filter instead, that way you dont have to worry about spacers att all. This mod is most suitablen for DSLR with mirror and use a threaded IR-pass on the lens.

Agreed, but 5 years ago did not have access to anything better for recording :)

I modified the 40D as I had it laying aroubd after getting a 5D MK2 and no mirrorless alternatives existed from Canon. Nowadays that there are mirrorless alternatives, those are much better! A few years ago I purchased a EOS-M and modified that too, and with an adapter can still use then EF 17-40 L that works so well for IR. Please note that most lenses are really bad for IR. My recommendation is an EOS-M camera with the EF 17-40 L lens with an adapter. Getting good IR images are not cheap, only a few L-lenses are suitable as some of those were designed with IR in mind (cheap lenses never are). But yes 20D and 30D is similar, but do not rexommend it. (First one I modifies was a 10D, which was also similar inside)

Sorry for the late reply, gmail decided to notify me today of your comment.. at least it's still 2021! Yes the glass is necessary; When you remove the ir-blocking filter, you need to replace it with something else, otherwise the sensor distance will be so off that you cant compensate with washers, adding the 3mm glass compensate for it enough that sensor can still be mounted without modifying the camera more.

Its purpose is mainly to get the sensor/lens distance in a distance that can be compensated for. (Without the glass, you loose the ability to focus to infinity). Also, dont want the sensor exposed, better to clean glass than risk damaging the sensor each time you clean it.

Wow this was a long time ago. Unfortunately I don't remember how to calculate the glass thickness vs distance to sensor, but I only had the option of either 2, 3 or 4 mm glass to choose from at the glazier, where 2mm was too thin (infinite focus would be impossible) and 3mm being the closest on the other side, and was easy to correct with the spacers. There are probably a lot more information regarding these types of conversions nowadays as 8 years have passed since the video was created, suggest looking at infrared photography forums for information!

Hello. The video was not recorded to be a guide on how to do a conversion as there are already a lot of information about it online, but rather recorded as a documentation on what was done during the conversion itself as I could not find that previously for the 40D camera at the time of the surgery, and some information on what items was used in the conversion was added. A quick video like will not be enough to explain everything needed, you'll need to measure things, calculate things, figure out properties of materials you can find to purchase. For the how-to you can find a lot of information for example here: www.lifepixel.com/tutorials/infrared-diy-tutorials For calculating the correct spacer distance I just used physics formulas I found online and used the properities I knew about the material I used and got the correct distance from that, was not a lot of that available about it online related to infrared, but might be now since the video is soon 6 years old. The glass material is described as "standard float glass" in the video, which is basically normal window glass and the 3mm thickness was chosen as that was what the glacier had in stock. What thickess chosen is not important by itself (2.9 or 3.1, or 1 or 5 mm will work just as good), but what thickness chosen of a specific material determines how much you need to move the sensor itself with the spacers to get proper alignment as the optical properties of the glass differ from the parts that it replaces. But yes microscope slides will probably work just fine too if cut to correct size. (There are also a lot of information about this online) That being said, I strongly recommend that if you're interested in infrared photography, that you modify a mirrorless camera such as the EOS-M. It's much easier to convert, and since you dont use the optical viewfinder anyway when taking IR photos, you get away with a much smaller camera body, and with the EOS-M to EF adapter, you can still use the few EF lenses that are really good for IR photography as well (like EF 17-40). The reason this was converted that I had the camera body laying around but never used it for regular photography. But was later replaced with a modified EOS-M.

I cant unfortunately, I took it out and measured it before ordering, but not sure what size it is sorry. Perhaps for the 10D you might find additional info here www.lifepixel.com/tutorials/infrared-diy-tutorials/canon-10d

Edit: Now that mirrorless cameras exist, please do consider modifying one of those. I modified a M100 and its so much easier both to modify and to actually taking photos with it, since you get perfect focus with it, even if you slightly messed up your sensor distance measurements.

I dont know as I've not open a 50D, but I'd imagine they wouldnt have changed too much between models :)

i know I am kind of off topic but do anyone know of a good site to watch newly released series online ?
