As the canon have announced the new eos7, it is noticed that this camera comes from the same generation of eos rebel2000 and eos3.I am a user of eos 5QD, now I am wondering if the eos 7 would aotufocuse even at f/8, like eos 3.Has anyone tested this capability ?

The 1V and the 3 will AF at f:8, the EOS 30/Elan 7 and the 300/ Rebel 2000 will not. As soon as the camera senses an aperture smaller than f:5.6 it shuts off AF.

However, if you use an f:5.6 lens and a third party 1.4X TC the results will be an f:8 lens and it will AF, but rather poorly. So the capability has always been there. In fact that's wy the cheap 100-300 f:6.3 and 28-300 f:6.7 lenses still work on Canons. They just report/lie to the camera that they are really f:5.6 lenses. This has been my experience on a Rebel G, Elan II and A2. Whether the 7 is any better at it I don't know.

I have heard that the 3, Elan 7 and Rebel 2000 all need more light to AF than the 5, Elan II and Rebel G. It seems the new CMOS sensor technology that Canon is touting has a deficiency in low light.
