If anyone is looking at picking up the
Pentax 55-300mm F4.5-6.3 HD DA ED PLM WR RE Lens i'd recommend taking a look at the current offer from Bristol Cameras.
£300 (with offer discount) including postage and a Kenko 58mm UV filter thrown in for good measure. Cheapest i could find anywhere for it so picked it up
They do seem to have decent prices on a lot of their Pentax lenses as well.
Aware that isn't with Park Cameras, so sorry for hijacking the thread Cerebum, but thought someone might be interested.
P.S - additional thought. Maybe we should spark up a thread for Pentax Sales / Offers in the UK?
