I need a 67mm filter for a 17-85mm Canon. I have looked at all the normal places B&H,AD, ect. I really don't know what I need for general purpose nor can I find the answer by a site search.

There is a Hoya 67mm HMC 82A for sale on site. Checking it out I find 82A is a color converter filter. Now I'm really confused!! I can't find a clear explanation of a color converter.

HELP, newbie wwwould be lost if he wasn't so confused.

At this point just as a all purpose walk around while I try to figure out what
I'm doing.

I mainly wish to protect the lens.

I just finished reading the entire filter sticky and still don't know the purpose of a color converter.

I believe now I just need a good 5 coat protective filter from what I read on the sticky.

thanks for thr reply.

Get a lens hood. That will give much more protection and serve a useful purpose besides.

Colour converter lenses do essentially that. They were used when film intended for use with one type of illumination (say daylight) was actually used under another (say tungsten). They are essentially irrelevant in digital photography since white balance is easily adjusted.

I don't understand. How hard is it to type "82A filter" in Google?
You got a limited, technical and confusing explanation from one particular web site. Flash news for you: it's not the only one explaining filters out there :)

slkfis,
The type of filter you are looking for is a UV filter,
as it is mostly used for protecting the lens, some UV filters help reduce haze also.

Here in this topic: Test of 20 UV filters <-- click to see there shows a link that compares 20 different UV filters as some reduce quality more then others. B+W UV Haze MRC had the least light reduction and is the UV filters I use on most of my lenses.

Like xarqi suggestion, a hood does offer excellent protection with no reduction in quality and is another option. :)

Thanks John B and Xarqi for the replies.
I have a lens hood but wanted to add a protector just because I'm clumsy sometimes.

The filter article shows me what to buy.

Wow, I never realized rodinal was so perceptive!!
