> Printing an 8x10 from a cellphone is challenging, and the grain and imperfections are magnified.

Have you verified this personally or seen any data on this? I find this claim very hard to believe. I make several 24x36 prints in a year (albeit from APS-C and FF sensors, but sometimes heavily cropped) and 8x10 is a tiny size that should not present a challenge for any modern cellphone's sensor.

I've used online printing for my cell phone, even pictures from latest iPhones, and they look grainy at 4x6 or 5x7. Maybe it's just a poor printing service. But I spend a lot of time on my computer looking at photos, and the cell phone pics don't look as good. I think some rigorous testing would be a very fun project.

I have been meaning to shoot a roll of ISO 16 film, the CMS20 II by Adox. They claim it can resolve up to 500MP of details.

Would be great to compare to results to full frame with adapted film lens.

Here's their film page with sample pictures: http://www.adox.de/Photo/adox-films-2/cms-20-ii-adotech-ii/

My canon is currently mid-roll with infrared, so it'll be a while before I get around to using it.
