Banding is very rare with Horizont unless you accidentally touch with one of your fingers rotating drum on the top of the camera, but again, with Horizont you can expect everything. They are amazing cameras when they work properly (as with any other camera). I absolutely LOVE them all! Old (metal ones), 202s and S3s.
banding resulting from light-leak.
similar overexposure with too slow rotation at start with widelux 1500 and widepan 140(despite smaller image-110 versus 122mm) at 1/250. thats why we dont have that in Horizon 205 PC with its 1/60 and slower exp. times.
but with 202 also a lot of banding-problems. my repair-man had to rebuild-adding a new drum.
also reflexion-problems.
widelux 1500 was badly built- first batch. then improved. with widepan 140 everything was better(w1500-copy)
only noblex was the best short-rotation pancam. with also some disadvantages. had one of the first for long testing-could compare with w1500.
from horizons 35mm format: S3pro was best if only they would have used the old lens. the new "better" lens gives unsharp results at full stop-down at f16. reported endlessly. comparison indoor shots gone in pbase. yes i had filmrail-shim to get better DOF. it was at 5m and showed clearly image of S3pro is not as sharp as from 202. inspected with 30x loupe. in 12x print maybe one cannot detect the failure. but the large size 24 x 58mm is made to be enlarged big.
