The Leica 111 is similar to the model 11 but with the addition of slow speeds of 1 - 1/20 second and eyesight correction. The addition of the slow speed mechanism necessitated the top housing being re-modelled. Later model 11s also used the modified housing. The camera was originally produced in a back/nickel finish, shortly followed by a chrome model, a few models are finished in black/chrome. Other minor variations exist, most notably the size of the bottom plate locating pin and the addition of neck-strap lugs. On late models the re-wind lever has a cam that passes into the speed dial housing.

There are differences in the cassette tins, the early type has plain, flat, top, later it has a deep circular indent. Other versions of the reflecting finder have a swing-in negative lens for 35 mm and 28 mm wide-angle lenses.

The STARE copying stand is probably an early example and differs from that shown in catalogues of the time. The column is only 18" high rather than 22". The camera lens is off-set from the axis of the column by about 40 mm giving a lop sided look to the stand, on later models the bracket centres the lens with the column. The feet of the stand can be set up to 17" apart, the rear part of the stand is calibrated to this distance, but the height of the column only allows for originals up to 9" wide. When set to infinity with the no. 2 close-up lens the image width is about 8" with the camera at a height of 15".
