Welcome to the forum.

To answer your question, a polarizer does a couple of things that can help your image -- it tends to reduce reflections -- so helpful if you are taking photos of water -- and it tends to make the sky bluer/grass and foliage greener -- particularly if you are shooting perpendicular to the sun. It is by no means necessary for most shots and could actually detract from some shots by darkening your exposure too much. I do think it is nice to have one in your bag and know when to use it.

Hi Mega, Welcome!

It's certainly not necessary to have a polarizer; but they do come in handy at times. Also depends on what lens you use them on, you can get vignetting on wider lenses. They do offer "slim" filters which does help in this case.

Welcome to the forum. I mainly use a polarizer in the fall. By cutting the reflections from the leaves, it really helps the colors pop.

You can edit/open RAW files on your computer so it not necessary. Only when you want to save final image, or upload it on internet.

RAW is sort of like a digital negative. It will have more information in it for developing an image, but in order to view it, or print it, it will need to be converted to jpeg or some other format like TIFF. You can use the Pentax software to convert it, or you can get something like Lightroom. I use Lightroom and it works fine to organize files and do general post processing.

I usually do keep the RAW files as well as developed copies. Styles change and sometimes you have an image you developed in a particular way and down the road, you wish you had developed it differently. It is a lot easier to do if you still have the RAW file stored some place. For snap shots, I often just shoot straight out of camera jpegs, as it saves time and the camera's output is decent enough for most normal purposes.

How do I edit files on my computer since I bought the Camera used without software. Which site would have the free software to do this.?

I use this software a lot, even though I do have Adobe Photoshop also. FastStone is easy to use, and has many features to work with your images. I think FastStone also works with RAW, but check to be sure.

FastStone Image Viewer, Screen Capture, Photo Resizer ...

I always like to have a filter on the front of my lens for protection. My fingers have mind of thier own sometimes. I'm much happier cleaning finger prints off a replaceable $50 filter than the glass of a $1000 lens. And on some of my camera, those filters are polarizers. That works for me. Some have suggested that when shooting sunsets etc, polarizers can cause banding, and before hearing this I did have some banding on images taken with polarizers that i didn't understand. But I can think of maybe 5 exposures out of 50,000 where that happened. The rest of the time it's all good.

Yes, it does. It handles both .DNG and .PEF and lots of others.
