Canon EF-S lens modification

How I modified a Canon EF-S 10-22mm lens to fit on a Canon D30.

I own a Canon EOS D30 and a Canon EOS 20D. I recently purchased the Canon EF-S 10-22mm lens and using a Dremel tool I modified the lens so that it will work on my D30 using the same techniques to modify the Canon EF-S 18-55 lens. I was worried at first because if I made a mistake I would have $800 worth of useless glass.

I removed the four screws holding the mount to the lens and placed a piece of plastic sheeting between the mount and the lens and then placing the mount back on with the screws. Using the Dremel tool I cut off the plastic extension on the mount and sanded it smooth. I then removed all four screws and removed the plastic sheeting and blew off any remaining dust and remounted the mount. I then placed it on my D30 and it worked!

I use my D30 everyday taking photos of houses for MLS and there are times when I need a wider angle of view than my EF 17-40mm lens can give.

Have you seen the guy on flickr (Sam Bennett) who just popped the plastic out with a leatherman? The Dremmel is not really needed... LOL!

Great work!. I modifed an EF 75-300 f4-5.6 so that a sigma 2X teleconverter would work by enlarging the "plastic baffle" at the rear element. Trouble was the glass elements then touched at zooms from 75-95 so it can cause some damage. Always need to be cautious with this sort of thing.

If you have one lens and want to switch it between bodies, here is the answer...

I did mount it to my EOS 1v and the image starts to vignette at about 14mm and at about 12mm the lens protrudes back into the mirror chamber and becomes a danger to the mirror. This lens is safe to use on all of Canon's 1.7 factor digital cameras and film APS SLR's. (D30, D60, 10D, 20D, IX, IX Lite)

Does the camera's reflex mirror hit the rear element or housing of the modified lens? Outstanding hack! I have a d60 and hope to do the same

Hello,

Can you add some images, to detail the action (for this part : "I removed the four screws holding the mount to the lens and placed a piece of plastic sheeting between the mount and the lens and then placing the mount back on with the screws.").

Thx
