Just a few days ago I received my Sprocket Rocket, and I have to say that it's spectacular. The great side of it is that you can take beautiful and panoramic photos with it, with or without sprocket holes, and the negative part is that you have to use a high ISO because otherwise your photos will come out dark and a little color dead.
So trying to explain a little bit the Sprocket Rocket, the characteristics are B-setting mode for nighttime/long-exposures and N for regular exposure, focus from 0.6m to infinity, you can set it up on cloudy or sunny, but I suggest to used it on sunny only on really sunny days, otherwise the photos may come out a little dark even with iso 400. The negative part is the lack of flash, but at least there is a hotshot so I can use the flash from my Diana F+. The best part of it are the sprocket holes, and that you can do double exposures.
When I start using my Sprocket, I loaded it with a Fuji film iso 100, just to try it out. But I forgot that I shouldn’t use low iso with the Sprocket because my photos would come out dark. That same afternoon I used a lomography film iso 400 with it. The weird thing is that even using a different iso, the photos came out similar. You can try B mode and keep firm your camera and see what happens or you can also try double exposures because this way your photos will receive even more light and become brighter and more colorful.
