Beyond that (or for close-ups), a single lens reflex (SLR) worked better. The only one around in the 1930s was the famous Exakta (Exacta outside North America). There were other issues with the Exakta &#8211; below a normal to medium wide \u00a0focal length, complex lens designs were needed to clear the built-in mirror. Initially wide angle lenses were uncommon. Angenieux solved this problem with retro-focus designs and massive degrees of geometric distortion, very evident when the frame contains straight lines, the camera is tilted, etc.<\/p>\n<p>To make rangefinder cameras into SLRs some companies built both focussing aids into their cameras (eg the Alpa). In other cases, a mirror mechanism was built into an extension tube sitting between the camera body and a bellows (for close-up with lens heads, or normal photos for lenses with a focal length longer than a medium telephoto.<\/p>\n<p>Of course mirror boxes, interchangeable lenses, bellows, etc all became obsolete with zoom lenses and the digital era &#8211; especially smartphones.
