Lens with fungus
- Thread starter apiwales
- Start date
Fungus spores are everywhere in the air - yes even in the lens kept from day 1 inside your drybox.
Fungus grows when the conditions are right i.e. dark, warm and humid environments. The only way to prevent fungus growth is to create a barren environment so that fungus will not grow (i.e. drybox).
Fungus do not spread to other lens. That's mainly an urban legend that came about because once a lens in a bag has fungus the other soon became "infected" with the fungus. What really happened was that the condition in the bag was condusive for fungus to grow inside one lens, and the other lens soon followed with fungus growth because it was in the same environment (i.e. the bag).
To us it seems that the fungus from the first lens had "spread" and "infected" other lens when the fact is that the fungus spores were already in the other lens - it was just the right environmental conditions which made it grow.

I left my fungus lens with the other lenses and though it did not spread, I brought the lens for claeaning and it is clean for now... but once the fungus had grown, there will be higher risk of a releapse and also, it could eat into the lens coating. For my lens, it eat a bit into the coating but it is not so visible for now....
I would recommend that you bring the lens and have it cleaned..... before the damage worsen....... but if it is a cheapo lens, maybe should consider disposing it instead.......
Did they say why they cannot clean it??? If the fungus growth was too long, and eat into coating, it will be too late and nothing can be done much...
Are you still using this lens???
If not put it in a zip lock air tight bag before putting inside dry cabinet for safe keeping... and if no longer in use... maybe can consider disposing of it....
A little off topic but...
1. Is PG Cameras a reputable shop? There reason I ask is because I've passed by their Peninsula Plaza store quite often and have looked at their used lenses in the store window.
2. SamTac, is the avatar that you use a Sigma UWA lens?
Samtac, I read the review that you sent me of the Sigma 17-50 f/2.8 and the review at Photozone. Both rate it very highly and yet the price is significantly less expensive than the Canon 17-55mm. Looks like it is a very good lens and a very good buy! How has your experience with it been so far? Unlike the EFS version from Canon, can the Sigma be used on a full-frame?
