new Sigma 20MPx 1/1/1 FF cam : What about the Heat ?
3

[ Coming from Scottely closed thread :
  Will You Get Sigma's 20 MP/layer Full-Frame Camera?  ]

I'm surprised nobody talked about the heat problem.
Because the heat dissipation challenge of the Foveon architecture was the reason given by ∑'s CEO when the Quattros came out, for the weird extra length of dp-Quattro bodies.
That lend me to think that the reduced resolution of 2nd & 3rd layers of the Quattro 1/4/4 sensor might itself have been a compromise in order to lower the heat problem and get a faster data processing.
That would go a long way to explain why they can't squeeze more than 20 MP per layer in their new FF project.

The fact that Sigma is taking back the challenge of 1/1/1, up to the Full Frame at that… might mean their new partner's foundry (TSI ?) made a break-through in heat dissipation technology, because for the rest Sigma knows the way.

ps:
(to Scott ) = I'll go for it, sooner or later, for the reason that I bought the 4 fixed length DPs ( DP1M, 2M, dp0Q, 3Q ) and felt a little tricked when the SD-Q/H appeared soon after —so I skiped those last SDs and feel fresh for the new generation.
