What kind of filter are you talking about? A UV, CPL, or a special filter that is part of the optical formula? Unless you refer to the last one, you do not need a UV or CPL.
The Tamron 112mm filter that goes with it supposedly improved performance...how I have no clue since those things usually make performance worse...

The winning buyer is a lucky dog though :-)

I can't remember where I've read it, but I am fairly sure the filter that is needed for optimum performance with this lens is the 43mm drop-in filter. The big 112mm filter is for protecting the front element. I am surprised (pleasantly so) that there's another drop-in filter mount in this set, putting a small 43mm polarizer on it would be much more economical than trying to find a 112mm filter.

Thanks,

43mm Glass is needed

You're correct - the filter is part of the optical path and the default option is a clear glass insert in its own holder. I would never put a big filter on a lens like this, especially with a special place for 43mm filters.

Several offers, but lens kit still available.

Indeed, any lens you place in the way of the light becomes part of the optical formula. If you place a Leica filter ($489), for sure the image will see improvement. If you place a $68 chinese-made filter, you will deteriorate the image. This lens requires a fine filter for protection. Otherwise, it is better to be left alone. Definetly, however gets this lens is a lucky guy!.

Sold!

The lens has now been sold. I have mixed emotions about seeing it go, but happy to see it stay in the Pentax community.
