Rollei 35S repair & common faults
Excellent coverageThe Rollei 35S is Heinz Waaske's ultra-compact scale-focus camera from the early 1970s, built around a fixed 40mm Sonnar lens on a collapsible barrel with the leaf shutter mounted directly to the lens and shutter plate. Everything is mechanical and needle-based rather than electronic, so most faults trace back to shutter lubrication, the collapsing lens interlock, or the CdS meter circuit.

Common Rollei 35S faults
Rollei 35S shutter won't fire
This usually isn't a shutter fault at all. The 35S has a safety interlock that blocks the release unless the collapsible lens barrel is pulled out and twisted fully into its locked position, so a dead release is often just an unlocked lens. If it's properly extended and locked and still won't trip, the release linkage or shutter itself needs a look on the bench.
Rollei 35S meter needle won't move
The CdS meter needle is coupled mechanically to the aperture and shutter speed rings, so a needle that sits dead usually means either no power reaching the cell or the coupling itself has stiffened with age. Worth confirming a battery is fitted and seated before assuming a fault, but a needle that stays still with power present points to the meter circuit or its linkage.
Rollei 35S meter reads inaccurate exposures
These cameras were built around a 1.35V mercury cell that's no longer made, so a modern 1.5V equivalent will read consistently over or under. Add a CdS cell that's drifted with decades of age and the needle can be some way off even at the right voltage. Consistently wrong exposures across the range point here rather than at the shutter.
Rollei 35S shutter sounds slow or hesitant
A leaf shutter built into the lens plate like this one relies on light, even lubrication to snap cleanly through its full speed range. Old grease thickens over the decades and drags the blades, showing up first as sluggish slow speeds and eventually as sticking at all speeds. It's one of the most common faults on a camera this age, and a mechanical one rather than a battery or meter issue.
Rollei 35S film advance feels stiff or won't wind on
The wind lever is mechanically linked to cocking the shutter, so resistance here often means the shutter mechanism is dragging rather than a fault in the advance train itself. Worth checking the rewind knob isn't left engaged, but a stiff wind or a stroke that won't complete usually means the shutter and advance linkage need examining together.
