While Rollei 35 launched in 1966 made a great seller, other camera manufacturers, followed its success, introduced compact 35mm cameras which were far cheaper than Rollei 35, and some of them were at about a half-price of Rollei 35.
Under those circumstances, Rollei developed Rollei B35 - an intermediate version of Rollei 35 in 1969.
Listed belows are major differences between Rollei 35 and B35.

• Built-in meter was changed from Cds meter to Selenium meter.
• Slowest shutter speed was changed from 1/2 to 1/30 sec.
• Aperture & shutter dial's positions were changed.
• Lens was changed from Tessar (& Xenar on later model) to Triotar.

Although Rollei B35 is a kind of a downgrade version, we can find several attractive points that the camera body was lightened about 100 g from 370 g to 265 g because the material of the body was changed from metal to plastic, and the battery is not needed for exposure meter on Rollei B35.
