One thing to be aware of when purchasing from flea bay (eBay) and other places is look for any instances of fungus matter inside the lens elements. It can be either in the front or the back. You can't clean fungus easily with these lens since the cost to have them cleaned is not proportionate to how much they cost. The expense is more than the purchase price. Nothing makes you feel worse than a huge spot of fungus or the beginning of fungus growth. So make sure you double check and look over more than twice over pictures by sellers online and in person.







There are remedies out there that say you can destroy it by placing the lens on a windowsill and let the sun take care of it. This can be met with some success but in actuality may cause the lubrication on the aperture blades to run or even leak causing the aperture mechanism to stick and lock up rendering it useless.



















So take these words of wisdom and inspect lens merch with care.



Gratitude.
