Fun with MF Achromatic Digital Backs

About that....

I just heard from Daniel at Monochrome Imaging who said at this time he can't convert that sensor (the IMX161 in the GFX/X1D), and that he doesn't see that changing any time in the near future.
Too bad. If the GFX50R pans out for me I was cintemplating converting one to monochrome for walk around use.:cry:

Guess I'll have to stick with my IQ3100 Achromatic for now.:clap:

Paul, outstanding work. You put 830nm for the IR filter.

I'm curious which brand or format do folks prefer using? I've got various from B+W 093 and Hoya 072 - all circular. I'd like to be able to have all my filters in 100x100 in the LEE holder, but LEE only makes the polyester sheets.

These are from Mckee Gardens in Vero Beach, Fl.
