Just wanted to share a little story, please note that i was probably STUPIDLY lucky and i doubt this could happen again, but i digress. Here we go.
Around 3 or so months ago, me and a few friends had a Barbecure/Grill party in our neck of the forest. All was fine and dandy. Untill the storm hit us.
Now im not sure why i didnt zip my camera bag shut, maybe it was the influence of a couple of drinks, maybe the suprising and savage arrival of the storm. Either way we ended up huddled together under a tree for warmth, while Hurrican-force winds and buckets of rain pelted us. The camera bag was drenched.
After a good hour our optimism waned and we decided to leave as fast as possible.
Fast forward to the next morning. Taking my equipment back out of my bag, i was mortified as i opened the rear lens caps of my 2 sigma primes.
Both poured droplets of water out of the barrels. Needless to say i was devasteted. Water was visible between the elements of my sigma 50.
Not really knowing what else to do I put buth lenses in their respective bags, and added a few of those silicon-moisture absorbant sack thingies.
After 3 days my first moment of joy: The sigma 20 1.8 WORKS AGAIN.
Focusing, metering, doing everything it did before the storm. However the 50 was dead.
Autofocus didnt budge, sometimes random error messages came when connected to any body, the whole works.
Was pretty bumed, but i could still use it for Filming where AF isnt needed anyway.
Fast forward again to 1 month later, absent mindedly i switched the AF back on. Now imagine the size of my eyes when it suddenly started focusing.
After putting it through its paces i was suprised to learn that it focused just as accurately as ever, the only differnce being that now its slightly slower.
All in all i consider myself lucky, but if you ever accidently drown a lens, dont trash it right away, if youre lucky it might come back to life
