After some searching I came across a set of images taken of the same subject with similar lenses and similar FOV...one from the K10D, and one from scanned 35mm film. (Sorry, could not find any direct comps for 120.)
Cable Anchors, St. Johns Bridge, K10D, Tamron 28/2.5 Cable Anchors, St. Johns Bridge, Rollei Retro 100, Vivitar 28/2.8
The photos were taken within minutes of each other on tripod at f/8. Focus for both shots was on the near edge of the buttress. The K10D version was shot in RAW and had the advantage of MLU on 2 second delay. Default USM was applied on import into Lightroom and the monochrome conversion applied there. The film version was shot using Rollei Retro 100 (Agfa APX 100), scanned at 4000 dpi (20 megapixel) with no USM on the Nikon 5000 ED. Contrast was bumped and exposure tweaks were added at scan time for artistic affect. The lenses used are pretty comparable based on a head-to-head testing done earlier this year using the K10D.
Here are detail crops from both images:
K10D, full resolution detail
Brightness and contrast were modified to match the film image below.
Rollei Retro 100, down-sampled 50%
To its disadvantage, the film image still has somewhat larger magnification, but I think that the results are pretty comparable. As I noted in my previous comment, despite this type of comparison, I still feel that my 35mm film stuff is not quite to the same standard as the dSLR. That being said, resolution is not the whole story. For B&W work, the K10D falls flat for many subjects. In addition, I have taken some shots with Ektar 100 that I am not sure that the K10D could have handled.
I was disappointed to find that I don't have any similar comparison sets for the K10D vs. 6x7 scanned on the Epson V700. I guess that can be my assignment for the week. After all, the bridge is still standing and I have plenty of film...
