Thanks for the great response to the query. We'll be using C1 to process the images as a way to eliminate variables.
The 35mm Schneider was selected as the closest to a 24mm lens that I have. It has many issues on the IQ180, but sharpness unshifted is not one of them.
We're using the 24mm PC-E on the Nikon as it seems to be the best of their 24mm lenses and it's also what's available to us. We will likely be using tilt in the test for front-back sharpness (for some images), but we won't be using shift as the 35mm is not usable on the IQ180 without being perfectly centered - LCC problems.
The 35mm Phase One lens is being thrown in as I have it and have never done a direct comparison against the 35mm Schneider. I'm aware it's far from being the best lens for the Phase system - the goal here is to see just how much poorer it is!
We'll be tweeting over the course of the test - follow #bigtest to keep in the loop. We'll also be discussing it on next week's Circle of Confusion podcast (
The Circle of Confusion). The video and full report will probably be out late next week or early the following week.
I'll keep monitoring this thread in the interim, and look forward to sharing the results with you!
Cheers,
Peter
