Review on Neewer 49MM Lens Filter and Accessory Kit for Sony Alpha A3000, NEX DSLR Cameras - UV CPL FLD Filters, Macro Close Up Filter Set, ND2 ND4 ND8 Filters, Pouch Cap Hood included by Jose Guzman

These are decent quality considering they average around $2.50 each. The ND filters aren't accurate, but they're close enough at 1, 2, and 3 stops to be used for basic videos and reasonable ratings. If you need to match lens shots with ND and no lens, they won't match and I wouldn't recommend relying on them for long exposures, but for gunshooting they work. Macro adapters are decent clear glass. The attached photo was taken at macro +4 on a 50mm 1.8 prime with a focal length of approximately 4 inches and a minimum focal length of 1.5 feet on the lens. It's also nice that a folding hood and hard plastic hood are included, but they're threaded so they can dig into your image on ultra-wide lenses.
