Rolleiflex 2.8 & 3.5 & Yashica Mat TLR: Übersicht aller Objektive und Bajonettanschlüsse (Bay I, Bay II & Bay III)

Rolleiflex 2.8 & 3.5 & Yashica Mat TLR: Overview of all lenses and bayonet mounts (Bay I, Bay II & Bay III)

Rolleiflex and Rolleicord cameras were equipped with bayonet mounts for lens accessories (caps, hoods, filters, and close-up lenses) starting around 1937.

The idea of this "double bayonet" is that the independent mounting of a lens hood and a filter is possible, with the lens hood mounted on the outside and the filter on the inside of the bayonet.

The bayonet mount was produced in different sizes depending on the time of production of the camera and lens:

1. Bay I (universally used abbreviation for "Bayonet Type I") is the mount used on cameras with the f/3.5 Tessar, Triotar, and Xenar.

2. Bay II is the version for the f/3.5 Planar and Xenotar.

3. Bay III is the mount for the f/2.8 Planar and Xenotar; it was also used for the Tele-Rolleiflex with the 135 mm f/4 Sonnar.

4. Bay IV is the version used for the Wide Rolleiflex with the 55 mm f/4 Distagon.

5. Bay VI is used for Rolleiflex medium format SLRs such as the Rolleiflex 6000, 6006, 6008, and SL66.

 

The majority of TLRs from other manufacturers like Yashica and Minolta usually have f/3.5 lenses, and the Bay-I mount is the most commonly used here. 

Here is an overview of all the cameras we know of along with their corresponding mount types.
