• The Rolleimeter: Do you prefer rangefinder focus? Rollei made a gismo called a Rolleimeter that affixes to the front of the open sports finder. There is a focus-spot in the center of a clear piece of glass that lets you align a double-image, just like an M-Leica!

• The Rolleikin: This is an adapter that allows you to use 35mm film in the Rollei. Why, you ask? Well, the 80mm lens is perfect for portraits in 35. And as you are only using the ‘sweet spot’ of the lens, the results are remarkable.
