Charlie uses the 55-110 zoom pretty extensively for his landscape shooting. He also does NOT show 100% crops of files on his site! (And I know why
) Anyway, I was visiting Charlie and Bill Atkinson right after they got their P45's, and we were comparing their files directly to scanned 4x5, among others. (These files later made it into the Luminous Landscape file comparison DVD -- still available on the LL site I think if you want a copy.) The common comment from each of us was that the scanned 4x5 showed a bit more detail, but we all agreed you'd never see that tiny difference in a print. Even the differences we show in the side-by-sides in this thread would be difficult to detect in a print viewed normally...
More to the point, this was almost two years ago and the raw converters have only improved -- back then, the P45 files did NOT show as much detail as what we're seeing now. Thus I am confident in claiming that this P45+ file is equal to or better than drum-scanned 4x5 from a detail rendering standpoint, which was pretty much my gold-standard target. Suffice it to say, I am really happy with my decision
Cheers,
