Any manufacturer of a reflex camera system has to fill in gaps in the lens range, knowing that most photographers will not buy every single lens because of personal preferences or use. Some buyers prefer a 19mm lens, others a 21mm, some need a 15mm, but not all three. Leica had the good fortune that prosperous customers might buy more lenses than they really needed. For a long period a gap existed between the 21mm and the 28mm focal length, not a problem for generations of photographers brought up on Leica rangefinder lore. Japanese manufacturers however offered 25mm designs, as did Zeiss for the Contarex, but Enna in Germany designed a 24mm lens and some others followed. There might be some misunderstanding that the nominal focal length is identical with the effective focal length, but this is most often not the case. The Elmarit-R 1:2.8/24mm has an effective focal length of 24.3 mm and can be rounded off to 24mm. A lens with a true focal length of 24.7 might be rounded to 25mm. Small tolerances in the production add some additional spread in the true focal length.

The 24/25mm focal length is a fine compromise between the 21 and 28mm lenses and with proper learning experience can create a pleasant perspective with a feeling of being in the scene.

The Elmarit-R 1:2.8/24mm is often referred to as a original Minolta lens. The true background is a bit more complicated. The original design is indeed a Minolta computation with glass from Minolta itself and other manufacturers. Leitz had adopted the computation. The lens is completely built in Germany. With more than 20.000 units sold it has been a very popular design.

The Elmarit-R 1:2.8/24mm delivered good performance at all apertures, but was unable to distinguish itself above the competition. It stayed in the catalogues unchanged for a long period, a sign that Leitz had no interest in improving the image quality.
