Has any one used or are using a teleconverter with their DSLR? and what are your opinions of them.

Maybe its a case of getting used to the one wheel system.

Don't buy anything from jessops! Their 'after sales sevice' is non-existent.

I have a Sigma 17-70mm which has noticeable piece of dust/debris behind the front element, I've tried a vaccum cleaner at the ring end and zoomed it in and out a bit to no avail.
Is there any way to remove the front element or get at the inside of it,I dont think it affects picture quality but would prefer to remove it before selling the lens.
