[Longimanus1975]

I am building up my underwater kit and have purchased a tokina 10-17mm second hand.

What I want to know from you experts is how do I test to make sure the lens is all ok?

Any help much appreciated

++++++++++++
Well, since you have already purchased ..................!

Any scratches on glass?
Look at the outside very carefully for any nicks and dings
Does the zoom and aperture rings rotate smoothly?
Shoot a cloudless portion of the sky and blow up on computer and examine for specks of dirt in lens assembly.
Don't flood it.

BTW, I'm not an expert.

I have checked out the general condition of the lens and it is very good, the zooms works ok, a bit of a noise when zooming, but I think that is normal as its the same sort of noise as another lens.

Not sure I will get a cloudless sky in the uk at the moment, do I generally want a pic of a single colour and then examine?

Thanks for your help by the way
