Ray,
I don't see high ISO shooters as primary customers of IQ180s. Would I need high ISO I would go for the high ISO champs. Now I have a humble Sony Alpha 900 and I only reluctantly use it above ISO 200. I guess that any camera I had I would only reluctantly use above base ISO.
Best regards
Erik
Mark,
That's what I thought, in which case I sure hope the IQ180 has better performance at high ISO then the P65+, otherwise it will still be marginally overshadowed by the D3X, at a real ISO 800 with both cameras.
