UV FILTER

[njallen100]

I Recently got a UV filter and I realized that it was giving me horrible lens flare :(, is that because it is uncoated or?? is that what they always do?

If you feel the need to use a UV filter then it should be a high quality multicoated one. Even then you should always be using a lens hood when flare can be a problem.

Well I don't really feel the need except it was suggested to me since it protects the lense, but its doesnt make senses to me to be taking a photo through a piece of extra glass.

I agree, although if you have a very good filter you probably won't notice a difference. Maybe just use the lens hood for protection and toss the UV filter.

yeah i agree. el cheapo uv filters are a waste IMO. i only use mine when i'm going to be exposing my lens to potentially dangerous things like saltwater spray, sand, etc... i usually use a lenscap to protect my lenses. one guy i read about on some forum had a uv filter break nd wound up scratching the lens surface in the process with the broken filter.

A lenscap doesn't let much light through to the sensor though - even more effective as always keeping the lenscap on is to leave your lenses packed in the Canon boxes in which they came!
What state would the front element have been in anyway without the filter on it?
There are many more instances (in my long photographic experience) of filters actually protecting lenses rather than causing damage.
The 16-35/2.8L and 17-40/4L lenses are not fully weatherproofed UNLESS they have a front filter mounted .
A good filter (UV, Skylight or Canon Protect - just an optical flat) should not degrade the image except where light strikes obliquely across the front of the lens - a hood should ALWAYS be used anyway to avoid this.

Are you using a lens hood?

Adding a filter in front of the lens increases the likelyhood of flare because you are adding another layer of glass for the light to pass thru/bounce off of.

Best bet is to use a hood to block the stray light source.

At least it isn't over $500 like the one for the 600mm L. :lol:

I've had my 75-300 III USM for two days now - been using a lens hood and a UV filter (Just a cheap canon one) and I havn't had any problems!
