Sometimes I get tired of the digital back thing : carrying the batteries (4), wake up cords , LCC card, memory cards, ...
And then the processing thing wich can take time for some shots.
And then the problem of keeping all these files.
So, I made a break and went back in time : I boughta 6X9 film back for my ALPA 12 swa. I put a roll of Fuji ACROS 100, shot, processed and scanned it.
What a surprise, the resolution is amazing (scan LS9000 at 4000dpi), the very fine grain of the film is here and I am getting 12800X8700 TIFF full of informations.
Then I gently put the negative in his protection.
Ok I still love my P25+ Phase back. But the combination of ApoDigitar schneider lens (47mm) with a fine grain modern black and white film outsdand all my hopes. Nothing digital beat this actually I think (maybe the special BW Phase back).
Are you looking for an outsdanding back in resolution for BW landscape : you've got it the ALP 6X9 back is the one.
I did not scan yet my rolls of Provia wich look fantastic naked eye.
