>bought a tamron 70-200 vc usd for my 5d2
>great lens
>now I am switching to Nikon (due to better lenses, tougher cameras)
my 70-200 tamron which I've always kept in a ziplock bag with silica gels in a drybox has fucking like 6 pieces of dust inside
>a few right god damn behind the front element, a couple specs behind the rear element

How in the fuck does this happen to an internally focusing lens with no push-pull zoom which I have hardly ever used (maybe less than 1,000 shots since buying it 9 months ago

I bought it new 1,000 dollars on a sale with a 1 year tamron warranty, and a 5 year store warranty which apparently doesn't cover costs of dust cleanings.

I wouldn't mind selling this lens for 700 dollars or something but, anything less would make me feel horrible, wat do
