hello all! I've modded my Holga yesterday to get to around f8 and f16. while this worked quite nicely, I can't seem to focus towards infinity when using f8. I've made the hole in the shutter plate larger - it is now around 7mm in diameter, same as the aperture, but that doesn't seem to help? Anyone else run into that problem? When focusing towards infinity, the focus does not seem to change. It seems to focus up to around 2 meters and then the sharpness seems to sort of stay the same? Is this just the inherent softness or did I mess up? thanks for any input!
