I'm really looking forward to see whether foveon is just more or less a marketing trick or it really makes a difference. It's really a shame that Sigma doesn't make any fixed focal lenght portrait lenses (medium tele, 85 mm or so). I guess 18-50 2.8 macro will have to do.
First impressions: Nice big vewfinder, only 5 AF points crummed in the centre, dial with only relevant modes (P,A,S,M no P&S stupid modes eg night portrait etc), AF seems pretty fast in low light, AF assist lamp. I'll write more about IQ during the weekend. That's the most important thing anyway.
