still impressed with the improved high ISO performance, not so much with H1, H2 or H3. but ISO 12,800 looks like my ISO 1600 on my XTi, plus if you run that through noise reduction software in post processing you could get a fairly clean usable image. i like the 1.3x sensor too, i have a feeling nightime sports photographers have been waiting on this camera for sometime. the 5D Mk II is still an excellent full frame option and the 1Ds Mk IV isn't far away so i think the complaints about APS-H will blow over soon enough. As for not changing the body? if it ain't broke don't fix it [] happy shooting
