Hi all!

I´m about to go out for a night shoot (will try and remake my urban challenge picture)... and I was wondering if an UV filter attached to the lens is good or bad.. or it doesnt matter maybe?

Mikael I have a UV filter attached to my lens permanently, mainly as lens protection. I am not sure if there are any advantages or disadvantages in using it for night shots, but so far I haven't noticed any problems keeping it on when shooting at night.

Ok, I´ll see how it turns out, will try it both on and off I think. Though the filter is usually permanently attached on my lenses too.

I´m leaving now...
thanks for your reply!

i also leave a UV filter attached all the time.
i dont think it would be much of a factor in night images.

the UV filter i think is about as minimal of a filter as you can use
and provides protection of the lense.

How important is having a uv filter?

Protects your lense from touches and scratches and doesn't slow down the camera...

I just use UV filters on all my lenses to protect them from scratches. I'm so rough with my equipment. And when I want to clean it, I just blow some breath on it and use a Kleenex. I'm not anal retentive enough to believe that picture quality will be dramatically degraded.

Replacing a filter is a lot cheaper than replacing a lens :)

The extra glass is going to give you more chances for reflections, particularly at night, also tending to reduce the contrast normally and at night, as it catches more light. Multi-coated filters reduces this effect, but a lens hood is really required.

If you aren't using a lens hood, then it wont make much difference - but you should be using a lens hood all the time anyway - also lens hood means you don't need to worry about hitting the glass.

I carry UV filters and use them when there is dust or sea spray blowing around, but I'm not careless enough to stick my fingers on the end of the lens anyway. I use filters when I have a reason to use them, that's about it.

That explains this picture below... I always wondered why when I took a picture of the moon (the bright thing on the left), how/why the reflection of it occurred on the right side. Now I know.

I agree with Gordon. Don't use unnecessary glass on the end of the lens.

and the UV filter remains on my lens.
