Is there a reason P1 is not on your radar as an option?
When I hear someone that loves landscape, wants the best quality, and wants great service/support it obviously piques my P1 spider senses.
Sure it is, what is YOUR credit card number Doug?? LOL
I was actually asked by the French govt. to consult with a little Israeli company named "Leaf". I did, and found them to be
quite bright and would actually impliment what was suggested. Advantage I have was past experience with Eikonix, AND I had a Howtek Hi Resolve Laser scanner, and my team developed a driver for it on SGI. Add to that a computer controlled Wing Lynch N2 film processor, pyrogalic based film developer, and was shotting Hassie 500CM and 4x5 sheet film, all B&W of course.
It took various iterations but when they reached the P45+ prototype, they matched the res but with better Dmax that I could pull out of my various film recipes and scanned at 8K dpi on the drum scanner!!
IF I had been smart, I would still be shooting that camera! Images were great!Oh yes, now Leaf is P1. LOL
For the years I have left able to get vertical upon waking, X2D is where I "plan" to end this journey.
But then, "plans" are only as good as our ability to live by them! :-)
