An ingenious tapered mirror allowed the size of the viewing lens (the top lens) 'internal compartment' to be reduced, and this smaller compartment was dovetailed with the bottom taking lens 'compartment', which decreased the overall size and weight of the camera.

The Rolleiflex TLR film cameras were notable for their compact size, reduced weight, superior optics, durable and simple mechanics and bright viewfinders. The Rolleiflex series is marketed primarily to professional photographers. (A companion line intended for amateur photographers, Rolleicord, existed for several decades.) However, a variety of TLRs and SLR's in medium, 35mm, and digital formats have also been produced under the Rolleiflex label. The "Rolleiflex" name is most commonly used to refer to Rollei's premier line of medium format twin lens reflex (TLR) cameras. Now when I see documentary films of the great photographers of the 1950s and 1960s using TLRs, I’m amazed that they can interact at all with the world they are capturing, outside of their crucial view through the upper lens.Rolleiflex is the name of a long-running and diverse line of high-end cameras made by the German company Rollei. I suddenly understood what I’d heard for so long about good lenses showing their quality at wider apertures and knew that I had the world at large to go back to and look at again. It made me stop and look much more carefully, which in turn made me rethink my photography and let go: throw the aperture open and let my eye roam in the depth of the scene before me.

For something so profoundly analogue, it’s immersive in a way that I’d only experienced in highly digital VR environments, all goggled- and headphoned-up (which I hadn’t enjoyed at the time). Nothing prepared me for the experience, though, in Denmark on holiday last August (2019) of unwrapping my first ever roll of 120, loading the Rolleiflex, with YouTube assistance, and trying to take pictures with it.
