Default Ultra violet filter?

Does an ultra violet filter make any difference if you're using a digital camera?

My guess is that it doesn't because I would expect digital camera sensors to be designed to be insensitive to u.v. - but I can't recall reading anything on the topic.

Many people like to have a UV or Skylight filter on the camera to protect the lens from scratches and fingerprints...especially cameras that have retracting lenses, people like to have a filter and lens tube (if available) on the camera at all times to protect the lens barrel.

I use the setup as Mike described. It also allows me to quickly add telephoto lens.

Does the uv filter affect image I have read that it has no effect with digital image since the media deals with that.

Some cheaper UV filters may absorb some violet and blue making it darker. Here's a page showing various filters in use on the same scene:

Can you explain what you mean by your comment about media? Media being the memory card (as defined by the industry)?

In this instance the word media was intended as a general reference to the media of digitally captured images.

I always use a u/v filter because i'd rather ruin a $10 filter than a $500-800 camera.

Thanks for the opinions - and I see the differences in the various pictures you've posted comparing results. I used Irfanview to slightly reduce the blue content of a couple of the pictures that were taken without a filter, and it seems to me that you can, to some extent, get a similar result that way.

The more cogent argument seems to be that the filter helps protect the lens. Now I'll probably go out and buy one....

I use a uv filter on my minolta 7hi simply because i don't want to scratch my lovely gt lens.
One thing i have heard is that if you do get a filter,get one smaller than 4mm in thickness as it otherwise will cause vignetting at wide angle.
