Is it worth servicing a fungus infested lens?
Hello All,
I am planning to buy a used lens for a better price. However, the lens has signs of fungus infestation.
My idea is to take it to Sony authorized service centre and get it cleaned/fixed. But, I am afraid, if it’s a good idea.
@sudhir sir and group, I know many of us might face this situation, what are your thoughts on buying a lens in this condition and getting it fixed by the authorized service centre?
After cleaning, if cared for and maintained well, are there any chances that the fungus might regrow?

hi Pramod,
I wouldn’t buy it if it has fungus. If you use canon, check canon site for rectified / refurbished / open box, they usually have good deals for these products.

Thank you Virag. I use sony and wasn’t able to find anything similar to what canon offers.

Depending on how much fungus is there on the lens, different techniques are used to remove it during cleaning. You need to understand that to access the interior of the lens, it is disassembled into its individual components, such as the front and rear elements, the aperture assembly, and the focusing helical. So it’s a delicate and serious process.
Also, if the issue is severe, ultrasonic cleaning is done which may remove some of the lens coatings, as the high-frequency sound waves can agitate the cleaning solution and cause it to penetrate the lens surface. And this may impact image quality.
So to cut the long story short, avoid it 😉
