I understand that optically the Pentax DA 55-300mm and the DA L 55-300 are the same. The differences being a metal mount, a hood and quick shift.
I only have experience of the kit lens (18-55mm) so no quick shift and there are plenty of DA L 55-300mm versions available from tiawan via
ebay.
But is quick shift really worth investing in? I understand it as a concept but in practice will it make a huge difference?
Many thanks
