I Guys,
I am seeking a 105mm front of lens filter for a Pentax 150-600 mm Lens, but so far have only come up with one from the USA at about $400.00, a bit steep, although a very good Ceramic one.
Anyway dose anyone know where i might be able to access one at a more reasonable price.
The size seems to be not really a shelf item as well.
Many thanks in advance
Leon
