Originally posted by krp I was excited to finally get my KX yesterday. I bought it from B&H for $629 with the 18-55 and 55-300 lenses. This is my first dslr so I have a lot to learn. Here are the questions I can think of now.
Quote: I know nothing about processing raw files. Should the format be pef or dng? Should I use Pentax Digital Camera Utility or Adobe Camera Raw? I have Photoshop Elements 8. Can I do much raw processing with that?
My preference is for PEF but DNG is a more universal format. To use your Elements with PEF, make sure you have the latest (version 5) ACR loaded up. I would do this either way. There are only a few (worthwhile) processing differences between Elements and the full blown photoshop. I use the latter but for ACR, your elements 8 should work fine. The Pentax supplied software, in my experience has crashed on every computer I've installed it on. However, if you have a good install and it actually works, it will mimic the JPG options of your camera including the corrections if I am not mistaken.
Quote: What exactly is expanded iso? Does it degrade image quality? Obviously it will look bad at 12,800 but what about iso100?
I would always start at ISO 100 and go from there.
Quote: Are there any disadvantages to leaving highlight correction, shadow correction, ca correction, and distortion correction on all the time? I did discover you can't do 4.7 fps shooting with ca and distortion correction on, so maybe all these corrections slow down picture processing?
More likely it's your card. A slow card will affect the write times from the camera memory to the card. The corrections do slow things down some and all of these can be handed in post processing. If you want maximum speed, shoot RAW only.
Quote: I also bought a 58mm cpl and a 58 to 52 adapter ring. The adapter does not stay on the lens well at all and the polarizer is too hard to get off the adaptor. I'm thinking of returning them both and just buying a 52mm cpl for my 18-55mm lens. That means I won't have one for my 55-300mm lens. Is that a good idea?
That's all I can think of for now but I'm sure I'll have other questions.
Depending on the CPL, some of them, I find tricky to use. With respect to the adapter ring, they are a pain in the butt because once you squeeze them just a Little bit, they don't want to turn. Lighten your touch a little bit and it may get easier. Doesn't help that part of the CPL turns with it.

You're welcome. Notice, your questions don't have anything specifically to do with Just the Kx. They would be basically the same regardless of the camera (other than certain features such as CA correction etc).
Welcome aboard
