For some shots,I added a Holga wide lens adapter or the lomo tunnel vision lensFearing the camera lens opening is too small, I screw off the lens and cut it carefully bigger so that to get enough light in. The aperture looks like somewhat F/5.6 . Not for sure though. The film is wonderful with numbers from backing paper and the grains. Can't love em more..
