IR and UV filters

hi,

just a quick q - should i be using both at the same time, or just the IR? i know the IR and polarizer work well together, but am not sure of whether UV and IR should be used concurrently.

thanks in advance

The UV is usually used as a lens protector so it is usually kept on no matter what filter you use. On top of that, since the UV and the IR filters works on opposite ends of the color spectrum, using them together shouldn't cause any problems. (Actually the IR filter eliminates all colors except for "colors" in the IR portions of the spectrum. That means that the UV filter is superfluous and not really required. But it won't hurt to keep it on.)

Agreed. But what about lower light transmission due to two filters, and which should be closest to camera. Any thoughts?

-CPW

Cowboy, for most practical purposes, the light loss should be negligible, assuming one is using multicoated filters.

And, as far as which one should be closest to the camera is concerned, since the UV filter is already on the camera, that one would be the closest. If you are going to go out of your way to remove the UV filter to install the IR filter first, or if the UV filter is not on the camera yet, then you might as well keep the UV filter off and just attach the IR filter.

thanks for the info.

i just wanted reassurance cos i couldnt be bothered changing filters all the time and putting the uv on and off and on and off and on and off (u get the picture).

thanks again.

Please, would someone give me the url of a place where I can buy a IR filter for my G3? Thanks,
Paula, Italy

i got mine from www.lensmateonline.com - good prices and cheapish delivery. alternatively, try ebay locally.

I have just purchased a G3 - a wonderful camera! Could you please help me to understand what adaptors, etc. I would need to attach a UV filter to it? I like that filter for protection. I am bewildered by all the choices on lensmateonline... still kind of in the slr, film camera mode...!

Thank you!!

hi lowtech,

well it depends on your budget i guess - some people get both the 52mm and 58mm lensmate adaptors. you need at least one of them - the advantage with the 52mm is the filters are cheaper generally but either one is fine.

the adaptor itself is threaded on one end so you just need to buy that and then the UV filter to protect your lens so it screws right onto the adaptor.

aside from that, buy whatever else you want/"need" and you're all set .

hope this helps.
