Nikon/ DSLR Users I need your

I'm going to buy a lens hood(hb-45) and a lens filter(52mm Circular Polarizing Glass Filter) for my Nikon. I'm using a 18-55mm VR 1:3-5.6 Lens and will soon purchase another lens 18-105 or 18-200mm lens. I usually do photo shoots or events such as parties/weddings. Will me buying these products benefit me with my current lens, 18-55mm, and my future lens, 18-105/ 18-200mm?

You'll probably need a different hood/ filter for the new lens.

If your lens didn't come with a lens hood, I really wouldn't even bother buying one. The only thing a lens hood does is protect the lens from impacts, water and possibly some dust. If your lens is not weather sealed, you shouldn't be out in those conditions anyways. You might want to check reviews on the lenses you plan on purchasing, at your price point I would rather go for a (Tamron Autofocus 28-75mm f/2.8 or 50mm 1.8 prime) and (Nikon 70-300mm or 70-200). Your 28-75 and 50mm will cover 75-90% of event photos, longer focal length for the ocasional extended range. I have the 18-200mm and you'll never find it mounted to my camera, instead you'll find the 50mm until I get my Nikon 24-70mm f/2.8.

I just recently did almost the same thing for my Pentax Kx camera. I purchased a B+W 49mm circular Polarizer for my 50-to-200 Pentax lens. It is an excellent filter, BUT it doesn't have front threads/ I presume adding a screw-in lens shade will cause vignetting. So I need to order the Pentax shade which fits "behind" the filter on the lens barrel. Having used circular polarizers on other cameras should be a great help on your photo shoots and scenic's. However, I'm not sure about weddings. Although I'm a professional wedding photographer as 99% of my shots were in our wedding chapel. You may want to check with the likes of "chat" on the B&H Photo web site. They are very helpful in these matters. Also when shooting film, the practice was to purchase the filter to fit the largest diameter lens thread and use step-down rings for smaller diameters, like a 52mm down to a 49mm.
