I went out to the Stanford Church this afternoon during lunch and tried alot of different combinations of lenses and shooting. I took a bunch of shots outside with the contax 35mm PC, schneider 28mm PC, canon 90mm TSE, canon 24-105, leica 100mm macro, canon 85mm/1.2 II and compared with the Hasselblad H2 with 35mm, 50-110, 100mm HC lenses. I went inside the church where most of the surroundings were dark with the sun coming right through the stained glass. This should be interesting for DR comparisons. Nonetheless, this is the first comparison I have looked at. Both images were taken at iso 100, f8. For the canon shot I used the 85mm 1.2 and for the hasselblad 100mm/2.2 lens. i used mirror lockup with the hasselblad but could not find the mirror lockup on the canon so not used. I am showing a resized image field and then a 100% crop. I used the same parameters in CS3 to convert. I placed the color temp and tone at 5700/-8 and you can see there are very different colors. The true color is probably in between but closer to the leaf. I should drive by again to check. I had sharpening set to 25/0.5/0.25. My conclusion is that for resolution, the two are closer than I had anticipated. However, the Leaf does give more fine detail and my playing with the images post conversion suggests you can extract alittle more fine detail from the leaf but I do not know the optimal processing for the canon yet. So will be interesting to compare with the 24-105 image as i suspect the canon 85mm 1.2 is making some difference here. I am ok if there are any problems you see with this test.
