Hi, Have just purchased my 1st DSLR - Canon 400D + 18 -55mm f/3.5 - 5.6 IS lens and to compliment that have bought an EF 70 - 200mm f/4.0L USM lens. Should I buy some filter lenses, and if so, are there pro's & con's with these as well?.

Also, what other lens, that is not too expensive, would compliment this purchase. Have been looking forward to learning more about photography for years. Now I have the time and - almost - the money...

There are protective filters such as UV filters. Digital camera's aren't affected (much) by UV light. Some people like to use a UV filter as a lens protector. Others will do so only in the most harsh environments such as salt air, blowing dust or sand. All filters will degrade your image to some extent. The better the filter, the less the degradation.

There are other filters that alter the image you capture. Some people prefer to use polarizing filters to reduce glare and contrast. For digital's play it safe and get a circular polarizer type rather than a linear type..

The higher end filters will feature better optical glass, better coatings, and better construction..

You want to get multicoated filters. IMO the progression from barely adequate to good is: Hoya HMC, Hoya S-HMC, B+W MRC, multicoated Heliopan. (I am one that only uses filters when absolutely necessary.).

Scope out the links for the various brands on for some introductory information...

I use UV filters for protection on all my lenses. Here is a link to informal test I did with a L lens.

Many thanks for your info on filters. I had been told to use them to help keep camera/sensor clean. I will check out the photofilter site and learn as much as possible before buying or using.Thanks again..

A filter won't do anything to protect the sensor, it will only protect the front element of the lens. having spent the money on an L lens, I would definitely want to protect it with a good quality filter..

The most useful filter in terms of improving an image is a neutral density grad. I would recommend going for a 'square' filter system such as Cokin P.

And I don't use filter on it nor the 17-40L. I use the lens hood ALL THE TIME..

Having said that, I do own B+W MRC UV filter for the 70-200 and the Hoya Super HMC for the 17-40 if I shoot on the beach and dusty areas..

If I were you, I wouldn't consider a filter for the kit lens. Rather, spend the money on a good Circular Polarizer..

Another lens that you should get is the 50mm f1.8. Best bang for the buck. Johnny

What I think you should get as far as filters is a Circular Polarizer filter. But, first get a Cokin Adapter for each lens you have then get the lens hood then the filter to go into the adapter. Check the web site for Cokin and it will explain what you have to do. Do not I repeat do not get the regular Polarizer if you want your auto focus to function properly. Then check the list for Cokin filters that appeal to you. You may also check out the gellatin filter adapter.

There are a lot of gellatin filters in the industry that only come in that formatt...

Absolutely. If you want to protect the front element of your lens use a lens hood when shooting and cap when the lens is not in use...

Comment #7

Supposedly Cokin filters are not to good.I am trying my first grad fillter setup.I got it from would only get one filter see if you like it...

Comment #8

If you intend doing any landscape photography the one essential filter is a polariser, graduated ND filters also can be very useful to "even out" different light levels..

As already mentioned buy good quality ones !!.

You might want to consider one for the 17-40L. That lens isn't weather (and dust) sealed unless a filter is on it..

Also, the hood that ships with the lens doesn't offer much protection, to either the front element or from flare. You might want to consider the hood from the EF-S 17-55 (EW-83G) or 24/1.4L (EW-83DII)..

Finally settled on a B+W MRC UV multi-coated circular filter. Had to buy from Hong Kong as it appears the main filters sold in Australia are Hoya. Couldn't find any Heliopan filters unless I bought them from the US or Canada. Costs prohibitive. Will try this before purchasing any more. Thanks again for all the input...
