Question about filters

Hi

Is it true that digital sensors are not UV sensitive and therefore do not require UV or skyslight filters other than to protect the glass?

Not sure abt the sensor bit... but I need one to protect my lens front element... filter and lens hood work hand in hand in this area... hehe.

My experience is any light, including UV, that touches ANY film or a sensor willl have an effect on it.

I use UV, Skylight, and 81c's on my D70 lenses. Favorite is the 81C.

Of course protection IS an issue.

Are you using 81C as your protection filter, If so won't your all your photos be too warm?

Cheers

81C as a standard filter? might as well just change the white balance

Try it, you will like it. Each to his own.
No, the pictures are not too warm. I guess it depends on what you shoot. I shoot in SE FL USA. Either bright blue sky or shade or overcast. 81 series helps. Also, neutralizes the bluish tendency in flash photos.

As far as "white balance", no it does not give the same effect. The filter keeps UV off the sensor.

Generally, UV or 1A filters are used for the main purpose of protecting the lens. For other warming effect or filtering out of UV rays, you can just change it using the WB option
