Canon TS-E 24mm vs Hasselblad Tilt-Shift adapter

Hi,

Our studio just purchased a new Hasselblad H4D (don't ask why & don't ask how much it cost) with some lenses and a tilt-shift adapter.

OTOH, since I'm mostly photojournalist I'm considering to get for my Canon 5DMk3 a Canon TS-E 24mm.

However, some questions arise:

1. It is worth buying the Canon's TS-E since we have a tilt-shift adapter for Hassy?

I'm thinking now that in difficult lighting conditions Canon's sensor will deliver better results than H4D. Also, AFAIK (CCIW) the Hassy's CA is corrected in software while Canon's lens is 'free' of them. Another thing is that 5D3 is way easier to carry and setup than Hassy. What do you think?

2. Also, a related question - Should I wait for Samyiang's similar offering?

TIA for your feedback
