M42-mount is easier to use with an adapter. My adapter works well with 7D, 5D and 1000D but not with my newer 6D. The light metering flashes every 10th second. Think I need an adapter without microchips.

If you are Norwegian you will have no problem to read it.

With croped sensor size you will not hit the mirror.

I saw in YouTube one guy in Korea shoot vintage lense with his crop body Fujifilm. He turned ON the mode "shoot without lens".
I don't know t5i has this program mode or similar. My self also looking for the cheapest ways to use our old but solid lenses for manual focus in video and still pictures. Good luck.

There is no such mode for Canon Rebels.
