Would like to see your results. 16X is a lot of speed increase. I would think it might be very grainy, but, won't know until it's tried. As far as I know, All 110 cameras, with metering, were ASA 100 & 400 only. Either the tab on the cartridge was full length or clipped. My Minolta 110 Zooms do have a +/- one or two stops, so could expose ASA 400 at 1600. I'll have to try that sometime.
