With that adaptor you will get vignetting with the full frame sensor.
You need a wide T Mount adaptor if you don't want vignetting around the edge of you photos.
Takahashi make a good one for the Canon. I ordered one from OPT a couple of weeks ago. Fairly expensive, about $100 for the adaptor + shipping.
It works well and has eliminated the vignetting that the normal sized T Mount caused.
Here is an example of the vignetting.
