The best camera is one that still works!
Do you think the faults are of Sigma's doing or does the sensor also contribute to these...?
Must admit since seeing what Keith has posted from the SD1M, I asked my local camera shop to find a demo version to try out.
The sensor's faults are well known and not really an issue IMO ... to me they're characteristics rather than faults. As for the DSLR itself ... the AF is pretty flakey and the viewfinder is well behind the one on my D700. The rest of the problems like slow write times and the fact that the camera virtually freezes while writing to the card, not allowing access to the menu, was known to me before I bought it. I don't need a camera to be perfect in the way it works ... especially when it has the IQ we see from it.
The foveon sensor has a fairly steep learning curve IMO ... I realise that people like what I'm producing from it but I can assure you it's no 'gimme!' It takes some patience and understanding to get it's best. 🙂
