Lens Filters

by Twiki / June 15, 2007 6:51 AM PDT

OKay, I have a Nikon D80 with the 18-135mm lens. I was speaking to a friend that knows more about photography then me, however he does not use digital, and he was telling me I need a lens filter for my camera. Doing some research, I found several different lense filters. I am leaving in 2 days for Mexico and would like to get a lens filter, if for nothing else to protect my lense as I was told. What is a good basic lens filter? UV? Haze? 81A?

I do plan on doing more research and getting a lens filter kit from BH or another company, but I need something for my trip.

If your purpose is to protect the lens from scratches, the UV filter is what you want.

My lens chart shows that the 18-135 lens has a filter attachment size of 67mm.

UV filter is mainly for lens protection but a low quality UV filter may degrade picture quality. Getting a high quality UV filter like those from B+W and Heliopan will cost some money, and is used by a number of people to protect their expensive lenses. You have to decide whether it is worth spending that money.

What you may find more useful is a polarizer, which can help to deepen the blue in the sky and improve contrast. It will also cut down unwanted light reflection from water and other reflective surface. High quality brands are B+W, Heliopan and Singh Ray.

There are also color filters, warming filters, neutral density filters, graduated ND filters, etc. You can read about them to see if you have a need for them. Your camera should have "color filter" effect, and you can also do your magic with Photoshop. The ND filter however can give you some advantage of using slower shutter speed or wider aperture for some creative shots in broad day light, something that you may not be able to do with Photoshop.

But whatever you decide, you should consider getting a high quality filter since your lens is the eye for your camera.

You should be aware that a polarizer will reduce the light

reaching the camera's sensor. While I don't recall the specific numbers, it could be as high as 1 f stop.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
