Rollei B35 repair & common faults
Excellent coverageThe Rollei B35 is a compact scale-focus 35mm camera from the early 1970s, the simplified little brother in the Rollei 35 line, with production moved to Singapore to hit a lower price point. It carries a three-element Triotar lens on a collapsible barrel and an uncoupled selenium meter, so how it fails depends on that lens lock and on a light-sensing cell that owes nothing to a battery.

Common Rollei B35 faults
Rollei B35 shutter won't fire
On this camera the shutter is mechanically interlocked with the collapsible lens barrel, it can't release unless the lens is pulled out and twisted to lock. Check that first. Beyond that, a dead release usually means the interlock parts or the shutter's own firing mechanism have gummed up or worn with age, which is a mechanical fault rather than anything electrical.
Rollei B35 light meter reading wrong or needle stuck
The B35 uses an uncoupled selenium meter, its own cell reads the light and you match a needle by eye, there's no battery in the loop at all. Selenium cells weaken with age and years of exposure to light, so a sluggish or dead needle almost always points at a tired cell rather than any wiring fault, and it isn't something a fresh battery can fix.
Rollei B35 slow shutter speeds sticking or sounding wrong
The leaf shutter is a fully mechanical unit, and its slow speeds rely on a timing escapement that's the first part to suffer as old lubricant thickens with age. A camera that fires cleanly at fast speeds but drags, hangs or sounds uneven at 1/30 and below is showing textbook aged-grease symptoms in that escapement, common on a shutter this old.
Rollei B35 film advance stiff or frame counter not moving
A stiff wind lever or a counter that stalls usually traces back to the advance mechanism's internal gearing or the counter's own drive, both sitting deep in the body rather than anywhere reachable from outside. Confirm the film is actually loaded and taking up on the spool first, if it is and the wind still binds, the fault is mechanical and internal.
Rollei B35 film coming back fogged or with light streaks
The foam seals around the film door and hinge perish with age on any camera this old, and once they've turned to dust or gone tacky the door no longer keeps light out. Streaks or fogging along the edges of frames, worse in bright conditions, point at these seals rather than at the shutter or the lens itself.
