I'm still only starting out with my DSLR, but was wondering whether I should be using a UV filter or not? I have a D3100 with the 18-55mm, but also recently picked up the 35mm 1.8 too. When I purchased the latter, the camera shop offered me a UV filter quite cheaply which I accepted - to protect the glass really.

However, I have noticed some reflective ghosting appear on some of my shots, mainly when there is an artificial light in the scene. Do people usually take their UV filters off/on accordingly for the situation?

Cheers,

Grant
 
Cheap UV filters are definitely a no-no if you want good image quality, no matter what situation you're taking photos in. If you want to maintain the original quality of the lens, then you need to pay more unfortunately - something like a Hoya Pro Digital is good. Many people, though, say that a UV filter as protection is just not needed, and that the lens hood should be doing that job for you.
 
i've not shot a lot under artificial lighting, but i've not had any problem with my Hoya HMC UV filter, even at silly angles when shooting sunset.

also got a D3100, with 18-55mm kit lens, 55-200mm cheap lens and a 35mm f1.8G. all got the same HMC UV filter on them for protection.
 
I use a lens hood or for my really expensive lenses a clear protector that I use for transportation only in the bag in case the lens cap came off. Other than that I don't see the point of sticking a piece of cheap glass in front of a thousand pound lens.

It's a debate that always rages and arguments each way as to how it impacts image quality especially in front/sidelight and bright artificial light.

In bad weather, sandy environments I would fit one.
 
I have a good one permanently on all my lenses because I don't use lens hoods. Never had an issue with them affecting image quality.
