Tamron 90mm macro lens problem

[joeteds]

Hey guys
I was playing with my tamron 90mm the other day and noticed a tiny little green dot on the photos that I was taking so I looked very carefully at the glass at the front of the lens and noticed only what I can describe as a speck but it wasnt like a dust speck it was as if there was a tiny chip on the coating, I dont know if the lens is coated (im not very clever with the makings of lenses) with anything but thats all i can describe it as.
Does anyone know what this is and is it repairable ?
Thanks alot
Joe
p.s Ive just posted about a problem with my sigma lens too so I hope people dont think I treat my lenses badly Ive just been really unlucky in the last couple weeks.

Specks on lenses rarely, if ever, show up on photos. But I'm not going to be the one here to say definitely not. So I shall ask this. Have you tried the camera with another lens and seen if it produces the same green spot? I'm inclined to think it's a sensor fault myself.

I'll test that now thanks mate

Have a look at this link:

Don't worry, the tiny chip won't be causing major issues

Only thing I can think of is if it's flare from something, but if you post the shots in question up we'll be able to help a lot more
