跟大家現階段了解的差不多
高iso表現不錯,比起D3S在iso6400不會遜色太多
Resolution不管在jpg,raw也是有發揮18MP的優勢
尤其可見1D3與4的jpg直出差異,可見Canon在這方面的進步
引述DPreview的結論
Putting the EOS-1D Mk3's demons behind it Canon has produced an upgrade that's not just better, but delivers an incredibly versatile tool that blurs the 'sports camera/studio camera' line more than ever before. The Nikon D3S might beat it in very low light, but if you want speed and resolution the EOS-1D Mark IV delivers convincingly.
