hey as ever Im going to push you in a different direction
fist - what stills system do you use, cant you just get some adapters and use your current lenses
Things to think about..
you dont need fast lenses, because you wont be able to focus them
you dont need resolution because the camera does not have resolution
now I woould not buy online - it is so critical to get a lens with a nice movement on the barrel, light and smooooooth
heavy lenses upset your shot
for example I have a nikkor manual 50 1.2 and nikkor AF 1.4 and choose the second all the time because the focus pull is smooth
when you use an adapter it can have back lash which upsets your focus and shows in the shot
any wobble in the lens elements or connection to the camera show up if you use the camera in motion (the wobbling element moves the image around on the sensor)
some lenses I use.. on the 5d
canon 70-200 F4 (£300 used)
24-105 (£600 used)
nikkor 50 1.4
nikkor 35-70 F3.5 £70 used - bought for a joke !
nikkor 14mm
nikkor 28 3.5 PC
some I dont use..
nikkor manual 50 1.2
nikkor manual 135/2 (too stiff barrel)
nikkor 70-300 manual zoom (no lens collar - to flexible)
nikkor 24-105 - focus too rough
and my most used lens on the 7d, 16-55 tokina
I love zooms, never to zoom 'in shot' but to make setups between shots fast - even that 35-70 is great to trim a composition while on 'sticks' and has round bokeh at 3.5
Changing a prime can take ages if you have a matte box or follow focus or both
Things to decide..
which direction (nikon or canon rotation) - dont get a mixed set
Things to watch
baclash in focus
too much friction in focus
long lenses that do not have a collar support
too long focus throw
too short focus throw
most I would say is watch for any wobbles anywhere in the system
If find some tape can absorb backlash in adapters
I think the best lens for a 5d would be the nikkor 24-105 which is non extending - unlike the canon 24-105 which is floppy when extended and barrels badly at the wide end
I would consider expensive primes at the wide end because you dont get barrel distortion on wide primes unlike zooms, pretty much any 50 or 80 is good, even a $50 olympus one
barrel distortion is not easy to correct in motion AFAIK
remember if nikon come out with the next 'hot' DSLR you wont be able to adapt canon fit lenses because the FFD (flange focal distance) is too short
