Can someone confirm whether the update works with the h1?
Someone on here said it works for all the H cameras. For what it's worth, I shot some ambient light images yesterday at ISO 400 with an H1 & 80mm lens, and there did not seem to be any particular issues with slap (compared to my 5D2 with 50 1.4.) 1/100 at 2.8 looked pretty good. I also tested with strobes at ISO 100.
I did note just how similar the files look in terms of color, shadow detail, etc. between the p30 processed with C1 and the 5D2 files processed with DPP. They look very, very similar aside from a slight amount more detail from the Phase. I know here on the web people like to jack up the shadows by 3 stops and then compare cameras that way, but out here in the real world, I have never needed to do anything like that with any of my commercial or personal images. So jacking up shadows 3 stops to test cameras has no bearing on my reality. Even so, I tried it. And at +2.5 stops, the Phase does not seem to hold more detail in the shadows, but it does look smoother than the Canon. The canon had some red splotches at + 2.5 stops.
I really like the H1 body, and it's AF is a lot better in low light than the Mam/Phase IMO. Surprising, the H1 also felt lighter! And way better than the Contax (which tends to hunt in moderately low light my experience.)
