What filter should I get

[sbrian28]

I need a UV filter to protect my quality lens. I have ready that getting a cheap filter can degrade image quality when you have a good lense. It will be used on a lens made for a crop sensor. What brands should I consider? Do I need multi-coating?

[nothsa]

B+W and Hoya filters are the most popular here (I've got Hoyas on my lenses). You definitely want multi-coated.

I've got Hoya Pro1 D protection filters on my 24-105 and 70-200. Completely clear glass, so shouldn't impact image quality at all. They are fairly expensive, but a lot cheaper than replacing either of the lenses, and the impact on image quality should be hopefully non-existent.

I don't use filters. UV has zero effect on digital, at best they do nothing. At worst, they kill your sharpness. For protection, I always leave the hood on. For my 50mm and 100mm I bought replica hoods (5$ a pop) off Ebay.

Just my opinion, formed from my experience. YMMV.

Edit: There ARE times when the situation calls for the extra protection a UV filter can offer - I had a filter on for these shots:

Those flying sparks are kinda hot and I really didn't want one to burn a nice mark in my (then) brand new 50mm F/1.4. Filter was a cheapskate Hoya UV, no multicoated fancyness here.

You can wash a filter in the sink when it gets a bit greasy or covered in salt spray. You can't do that with a lens - one of the other reasons I always have a clear filter on.

Hoya HMC, good quality, not too expensive (compared to a lens or some other filters)

Thanks for the suggestions and comments. I have used them in the past but just the cheap ones so now that I am starting to buy better lenses I wanted to know if it made difference.

I have used B+W filters for over thirty years, They are
on every lens I own. I would never leave a lens unprotected.

I don't use UV filters as I feel they are a waste of good money in most cases, but if you really feel as if you want one, buy it from www.HVstar.net. Reputable dealer (I bought a CPL from them) and you will get a good UV filter while wasting the least amount of money possible. ;) Get a good CPL for that 10-22 while you are there. I use the Hoya Pro-1 Digital personally.

Good lenses are expensive and need to be protected, so I use B+W UV filters. And I also have a Hoya pro 1 CPL. They are always, always on my lens. I got them from hvstar.net.

I use B+W MRC F-Pro UV Haze filters on all my lenses and they are on the lens from day one. hvstar.com has the best prices on B+W filters.

UV filters on an expensive lens remind me of those clear plastic seat covers on an expensive couch.

Good lenses are expensive and need to be protected.....The "need to be protected" does not necessarily mean that you need to put another layer of glass in front of a lens.

All of my lenses are "good" lenses and all are (or were) fairly expensive. None have ever been fitted with a filter for "protection". All of my lenses - even those I bought in 1967 (my Nikkor lenses) - have glass that is in nearly pristine condition. All of my lenses have been fairly heavily used, and all have always had a rigid hood mounted when out of the camera case.

The lens hoods have provided all the "protection" that I have ever needed, though I don't go out shooting in sandstorms and such.

Proper cleaning technique (with proper cleaning materials) goes a long way toward keeping lenses in good condition. Most often, all I need to "clean" a lens is a few puffs with a squeeze-bulb blower. Beyond that, I use techniques that will not grind abrasive debris into the lens.

B+W, Hoya,Promaster.
All Multi-CoatedQuantaray offers multicoats as well, but I wouldn't recommend them. B+W MRC, Hoya S-HMC or DMC or Heliopan SH-PMC.

Sure, cheap UV filters. A lot of us have been using good UVs on our lenses to zero discernable effect.

[Joanne_CANON]

B+W are good filters for those lens. There are expensive but well worth it in the long run. There are also slim Uv filter's available in these that can help with problems of vinetting on some of the wide angle lens. ;)

Does anybody know how much difference would I see between these two:
- Hoya HMC UV Filter 77mm Multi-Coated
- Hoya PRO-1 Digital (UV) Filter 77mm
