35MM LEICA CAMERAS FOR MICROPHOTOGRAPHY
LEICA MIFILMCA 35MM MICROPHOTOGRAPHIC CAMERA
The Leica Mifilmca was Leitz's first 35mm microphotographic camera360 for photography on the microscope364. This device was introduced in 1928364. The advantage of using 35mm, instead of 18x24 cm format was that it allowed for significantly shorter exposure times364. Camera shakes, thus, were reduced to a minimum364.
The design of Mifilmca resembled that of a Leica I Model B but lacked a viewfinder and accessory shoe360. Instead, it featured a conical tube with a 1/3 magnification ratio, an Ibsor shutter, and a beam-splitter360. Early models had low (6mm) film advance knobs, while later versions were equipped with a higher (8mm) knob360. The original version of the Mifilmca, which included a fixed tube, likely emerged in the late 1920s or early 1930s360.
Eventually, Leica Mifilmca was replaced in 1930s by the Mikas microscope attachment364. The Mikas attachment could be mounted on Leica Standard Model E364.

LEICA KAFILMCA 35MM MICROPHOTOGRAPHIC CAMERA
In 1932, a new model of the Leica Mifilmca 35mm microphotographic camera was introduced, featuring a standardized flange, a removable tube, and a Mikas unit360. This updated version, known as the "Kafilmca", also included a pull-up rewind knob similar to those on Leica Standard Model E cameras360. In the same year, a new model of the Mikas with a 1/3 magnification cone was released360. The conical tube of the Mikas had a 39×1mm male thread360. The Mikas remained virtually unchanged until the late 1950s360. It was sold as a unit, but the shutter and beam-splitter were also available separately to allow for the use of various conical tubes that became available starting in 1939360. These tubes included: (1) with 1/3× initial magnification (code: GIIEF), (2) with 1/2× initial magnification (code: GIIMW), and (3) with 1× initial magnification (code: GIINK)360.
Some known Leica Kafilmca cameras included:
- prototype, without serial number and dated circa 1930, was offered but remained unsold at the 38th Leitz Photographica Auction on June 12, 2021385. This unique prototype had Leitz logo and "R" engraved the other way around, baseplate of early type, low-profile knobs, and chrome lens mount engraved "0+0.65"385.
- prototype engraved "1/9×" and without serial number was illustrated in Mr. Lars Netopil's "Rare Leica" book594.
- unnumbered Kafilmca camera was described and illustrated on pages 6-7 of Viewfinder, Volume 10, No 3, 1977. This camera, owned by Roger Bingham in 1977, had "dimpled mushroom shutter release, "pointer" film counter, etc". According to Mr. Bingham, the "KAFILMCA was produced around 1926- 27 and carried no serial number - only the "E. Leitz Wetzlar" trademark...According to the 1929 Leitz General Catalogue, it was intended for use with Microscope "SC" (Small Skin). It was furnished with a short connecting mount and a lens fitted between the earner a and the Micro Ibso (Ibsor) shutter. the shutter with my KAFILMCA, incidentally, has speeds of T, B, 1, 2, 5, 10 and 25...The lens in the connecting mount of the KAFILMCA produces an image that is round and fills about two-thirds of the standard 24 x 36mm frame; thus, the magnification is only about 1/6X....The connecting tube, Micro Ibso, etc., are removable from the KAFILMCA. The camera mount, with a wide flange, is threaded for approximately 30mm diameter".
- 3741, converted for plane film cassette, was illustrated in Mr. Lars Netopil's "Museum Leica" book in 2018596.
- 3781, which was auctioned off on March 20, 2010 at the Auction Team Breker
