oops, sorry. Maybe I shouldn't have said that. Had a Rollei 3.5E I used for years, and it IS on occasion--worthless. Try standing on the beach looking down into that dark screen. Try standing in the sun trying to see somebody in the shadows. You can't see ZILCH. They're slower to use than your Nikon, no close focus at all. Twelve pictures on a 5 or 6 dollar roll of film demands frugality.
Stack that against a 35 with 36 shots on a roll where you can shoot anything and everything and do your culling later. Remember, you'll be far from home with only that Rollei. You'll miss a lot of shots that you wouldn't have missed with the 35. On top of that, a Rollei is a "collectors item", which means you have to protect it all the time. Like carrying around an antique crystal vase the whole time on your vacation.
