Normal amount of dust?

[dorian7]

I just picked up a used 85mm 1.8 and it seems to have more dust than I was expecting for such a lightly used lens. Is this amount normal? I am particularly concerned that there are two larger specs in the rear element. I am very anal about having nice stuff so it does bother me some.

Sorry for the crappy pics, I only have my iphone at work.

I wouldn't worry about it. It's true that dust on the rear element will impact image more than on the front element.
I don't see anything that would be noticeable in results tho.

But if you are one those types that it keeps nagging you. Then by all means send to a local camera shop to be cleaned.

Gawd...I ONLY WISH my lenses had that little crap inside of 'em. That level of internal stuff rates a 0.5 on the Derrel Scale of Internal Lens Cleanliness, with 9 being, "Might possibly affect images shot directly toward the sun in high-elevation snowfield type environments, but probably NOT!" and 1 being, "Whatchooo talkin' bout Willis? Ain't no dust inside this here lens!"
