I have a Rollei 35S and have taken some great photos but also some misses - usually close up because there is no parallax correction - in the viewfinder there are hooks on the framelines on the LHS which you have to change the composition to within the hooks when close. Use Hyperfocal distance to get as much in focus - easier with narrower apertures- Enjoy!
Set the apeture and shutter speed,then match the infinity mark to the apeture you've set.Then you can read off the amount of distance that will be in apparent focus,fiddly on such a small camera but doable with patience....................................
