Here you’ll find everything about light seals for analog cameras — from suitable materials to replacement instructions. Especially popular are seals for common camera models where the original foam has become porous after decades, causing light leaks. All seals are made in Würzburg, trusted by over 25,000 analog photographers.
Light seals made of foam and felt decompose after 20–40 years. The result: light leaks onto the film, sticky residue inside the camera body, and often a jammed back cover lock. Our replacement sets make your camera light-tight again in minutes.
Universal Light Seal Sets
Analog 35mm SLR cameras from the 1960s to 1990s share nearly identical groove widths and depths across manufacturers. One set covers all common models — from Canon, Nikon, Minolta, and Olympus to Pentax and Contax, as well as Leica R, Praktica, Zenit, and Voigtländer.
Will the set fit my camera?
The grooves where the seals sit are standardized across manufacturers for analog 35mm SLR cameras — whether Canon, Nikon, Minolta, Pentax, Olympus, Leica R, Praktica, Contax, or Zenit. The widths vary only between 1 and 3 mm. The strips are cut to length and placed into the groove. The set includes seal strips in all common thicknesses for back, hinge, and film window. The mirror bumper is also included.
Why universal instead of pre-cut?
Model-specific laser cuts sound precise but have drawbacks in practice: the 1 mm thin strips for the back edge tear when inserted into the narrow groove. If something goes wrong on the first try, the entire kit is wasted. Universal strips are more durable, can flexibly wrap around any bend of the back, and provide enough material for 2–3 cameras — not just one.

Hasselblad Light Seal Kit
The magazines and backs of the Hasselblad V-System use narrow light trap seals. When these break down, medium format negatives suddenly show streaks at the image edge.
When should I replace it?
Typical symptoms: sticky residue when opening the magazine, visible light streaks on the film, detached foam seal on the hinge. The kit contains pre-cut strips — just stick on, press down, done. No tools needed.

Viewfinder Seals
Many cameras have a small view window on the back cover — through which you can read the type of film loaded. The seal behind it is a frequently overlooked cause of light leaks.
What is the view window seal?
The film counter view window (also called "Memo Holder") on the back of many cameras has its own foam seal. If it is porous, light falls directly on the last winding of the film cartridge. The result: overexposed strips on images 33–36 of the roll. Included in a 2-piece set — enough for a backup.

Complete compatibility list
Our universal light seal set fits all analog 35mm cameras with foam seals in the back cover. Here is the complete list — 414 models from 26 manufacturers.
Is your camera not listed?
If your camera is an analog 35mm camera with a back cover, the set will most likely fit. The grooves are standardized across manufacturers. If in doubt, write to us — we will tell you within 24 hours if it fits.
Why do light seals age?
Foam deteriorates — without exception
The original gaskets are made of open-cell polyurethane foam. This was glued into the grooves of the back cover in the 1960s and 70s. The problem: PU foam is not UV-stable and reacts with humidity.
- Hydrolysis. Moisture breaks down the polymer chains. The foam disintegrates into a sticky, tar-like mass.
- UV degradation. Daylight accelerates decay. Cameras that sat on shelves for years are often worse off than those that were used.
- Time factor. After 30–40 years, the foam is worn out on practically every camera — regardless of storage or brand.
- Felt lasts longer — but felt gaskets (common on cameras from the 80s) also lose their elasticity over time and let light through.
The good news: Replacement takes 15–20 minutes on most cameras. Remove old residue with isopropanol, insert new strips into the groove, done.
