(a bit like us...) Internal micro-dust is inherent in these objectives as well as a few small cleaning scratches on the front glass. Faults which are generally not affecting the result photographic On the other hand, the presence of mold (fungus) on the glasses internal are detrimental! This is the real "cancer" of mineral glasses! After a while they become embedded in the glass and it is often very difficult to extract them! They gradually spread and totally degrade optical qualities! Molds are recognizable by this: - White filaments - "Misty" aspect - Deep opaque inlays These molds appear when the lenses are stored in humid and polluted environments An external examination does not always make it possible to notice them! It is necessary to do an in-depth examination! An "endoscopic" examination! the only one that allows you to reveal these defaults To do so use a lamp in "against the day" The slightest defect becomes visible! you will be surprised at result! The next time you buy a lens ask the seller if such an examination has been carried out! and its result It's a safe bet that this "test" was not carried out! This lens that I am proposing to you does not have these serious flaws! The glasses are clear, limpid and transparent !!

Défauts qui  sont en règle général sans incidence sur le résultat  photographique  Par contre la présence de moisissures (fungus) sur les verres  internes sont préjudiciables !
