I have been looking at 1A Multi-Coated Filter OR UV Multi-Coated Filter. What is the difference?
What do you use?
Thanks,
Eric

Also, what cross screen filter do you use? A 6x or a 4x? Why?

| Protection? Lens cap & Lens hood. |

Straight UV filter..one for each lense I have.
To hyperfocal: Lense cap and hood do not 'protect' the lense glass. Once you take the cap off the lense glass is exposed. If you bump it or whatever, the scratch is permanently on the lense. If you have like a UV filter on (basically clear glass as far as the sensor is concerned) then you cannot scratch the actual lense.
The lense hood doesn't protect the lense, it just blocks light. |

Actually it does. I had my camera around my neck hanging down and a jerk came by and knocked into my camera with his phone hanging on his belt. He didn't even apologize and gave me a dirty look. If I didn't have my lens hood on I'm pretty sure that my lens would've been scratched.
Rude people suck.

The 1a filter is just clear glass and it doesn't affect the image in any way. In theory, it's the best choice if you want to add something to simply protect the lens surface. It's usually cheaper than the UV equivalent, especially when u consider multi-coated filters.

The only time I would ever add a UV or skylight into the optical path is maybe near sea spray or flying debris or for its actual purpose of cutting down distant haze. UV or skylight filters are just a marketing ploy by retailers to sell some sucker a hiogh markup item. Its a shame to, considering even the best of them lowers contrast & increases the chance of flair. Besides scratching a lens in normal use is actually quite rare.
However Lens hoods provide, depending on design of course, a hell of a lot more protection than a filter (especially on telephotos. In my decades of photography the only time I've had a lens damaged that a filter would have protected it, was when a drunk put a cigarette out in the front element of a len setting on a table unattended. But even it was covered by the best insurance, insurance.
Hood provide the best protection. Think about how many times in your life you've been hit in the eyes. Probably not many, because your eye socket acts as a hood for your eyes.

Hmmm... a butterfly hood does kinda look like an ashtray doesn't it. |

A good multicoated filter can actually reduce lens flare.

I have a horror of extra glass in front of a lens. I don't use it unless there's a reason to. A good reason would be shooting at the seashore, where there's a lot of salt carried in the air. Windy conditions in general, in a dusty/sandy environment. Glass is gonna get dirty in these conditions, and I'd rather clean filters than front elements.
But the best protection from hard knocks is a lens hood. I always, always use mine.

Any additional glass elements no matter how good can increase flare and lowers contrast. Even my B+W MC UV that I paid over $100 degrades image quality slightly under certain circumstances. Yes, under certain specific cirmstances it can improve an image, but they are not the multipurpose tools as many use them.
Compare 15+ element zoom lenses with primes with lower element counts, almost without exception they flare more. |

Read the article here at Luminous Landscape. If you want to use a filter all the time, go ahead, but realize what you're giving up.

WHen I first got my DSLR & lens, I also bought a Skylight filter as protection for the lens (As I have done on all my previous cameras). On about my 2nd day of shooting (I was shooting at midnight for the cemetary challenge), I noticed after an hour of shooting that nearly all photos had flair from the moon or lights. I then took the filter off & reshot some shots & .... No flair.
Since then I never have the filter on except for beach or motorcross photos.
Modern lenses built so the outer piece of glass is pretty scratch proof.
I also read the article in Spazmo99's post back then, and am very happy with my decision. |

Wow! Great article. I think I'm starting to switch sides. Why would I shoot with L-series lenses through a thin plate of glass?
Anyone else want to take the other side? (pro filter)
And, anyone have an opinion on what type of star filter looks best 4 or 6?
Thanks,
Eric |

And this is from the same article that states that glueing the corner off the sticky part of a Post-It note on the front of your lens won't hurt image quality - but a good multi-coated filter will.
I don't always use filters, but when I do I use good ones. There is a difference. And the coating on a lens can at times help cut glare. Maybe not so much on L glass that already has several coated elements, but with lesser glass with only one coated element the filter can make a positive difference.
As far as how the article states how hard it is to scratch the front element of a lens, I say from experience it is a whole lot easier then that.

i'm hard on my camera, so i always use a uv filter. i know i'm giving up some image quality, but i'd be giving up image quality if i were to scratch up my lens too.
if you're totally anal-retentive and really careful about your cam, you probably don't need it. i prefer to just throw it on my hand and wander around. i'm positive having a UV filter (that i can just wipe down with a t-shirt or something if need be) has saved me some trouble. |

actually it makes sense really if one thinks about it. why would companies like NIKON and CANON go through all the trouble to perfect lenses so that we can bung an extra bit of glass on the end of it and screw up all their hard work.
I have had filters on the end of my glass for ages but I think I will be taking them all of from now on, I always use the hood and keep the cover on when not shooting (and sometimes when i do shoot cos im stupid at times). I think this is a good thread it made me think, something teachers failed to do for me.

Yes. Why would they even bother threading the end of a lens so that a filter will fit. How stupid of them.

I aways have my clear glass filter on lens. Just this past weekend I was playing with the kids on block taking pictures of them and I leaned on the gate and realize my camera lens was right on it. ahhh checked it out and it was ok, lens would have been scrathed though..

From Mt Katadyn in Maine to jungles in Honduras I've never met anyone (this side of Nick Nichols) that was as hard on equipment as I am, but although I've destroyed alot of camera equipment I've never scratched a lens in a way that would have been provented with a filter. I read once that 95% of all damage to lens elements come from two sources mold & too agressive cleaning. |

So you can fit a filter on when you NEED one, of course :-) Just because it's threaded doesn't mean you have to mount a filter all the time.
