I'm a new DSLR user, and I'm trying to build my kit. I've got a new\nD80 with standard 18-135 kit lens.\n\nIn October, I'm planning on getting the Nikon 50mm F/1.8 D AF Lens,\nand 77mm Hoya Pro 1 Digital Circular polarizer with front threads,\nI'll need both a 52mm-to-77mm step-up and 67mm-to-77mm step-up filter\nrings.\n\nWhat are good and bad brands of step-up rings? I don't what to go\ncrazy on buying the "best and most costly" for such a simple item.\n\nI'm also planning on using the white balance lens caps that can be\nfound on e-Bay. Can I use a 77mm white balance lens cap over the 77mm\npolarizer filter?\n\nWhat about a lens hood? How is one used when using a filter and\nstep-up ring? And, what size to use?
