Best Setting for K3?

I have my K3 with the 18-55mm lens but Im not sure on how to get a fast, crisp image indoors. Im used to the auto setting on my old camera so can anyone help me get this to work please?

I am a noob.

You may want to use a flash or a tripod for those situation or use a higher ISO. The 18-55 is not the fastest lens in the world so it will need light.

Unfortunately, there is no one "best setting" that will get you good images every time, since conditions can vary dramatically form shot to shot, even indoors. Honestly, the best thing to do is to read an intro level to digital photography book and get a better understanding of how the various modes work. There are many inexpensive ones available at your local bookstore, and many good free ones to download online.

That having been said, the "Green" mode on your K-3 is the closest thing to an auto mode to use for the time being. But remember, you are holding one of the most sophisticated DSLRs ever made in your hands. To get the best out of it, you need to learn how to use it! Would you buy yourself a Ferrari and have a chauffeur drive you around in it?

1. Study the fundamentals of exposure. Understand what aperture, shutter speed and ISO mean.
2. Shooting indoor you'd probably want to be in Av mode, set the aperture as wide as possible (I believe it's f/3.5 at the wide end and f/5.6 at the tele end - it's the numbers engraved on the barrel) and either set auto-ISO or set ISO manually so that shutter speed is at least 1/focal lenght. That means that if you are at 18mm (wide end) you'll want shutter speed to be lower than 1/18s (1/20, 1/60, 1/180 are fine), while if you're at the tele end (55mm) you'd better be at 1/55 or less.
That's because camera shake is related to the focal length you're shooting at, as the arc of a given angle (measured in degrees) has a different length at different distances.

I hope this does not confuse the OP more

I've actually always heard this rule given in terms of the "FF equivalent" focal lengths (for the OP's benefit, 1.5x everything -- in this case faster than 1/24" to 1/83", instead of 1/18" to 1/55").
But in this case, with the K-3's Shake Reduction on, the speeds you mentioned are probably fine anyway.

I have found the K3 a big learning curve after the 1stDS. Just a matter of taking plenty of photos and note the different exposure settings. Trying some sports shots tomorrow.

I was trying to keep things simple, there's always time for details afterwards.

Besides, the Pentax SR system promises an advantage of 3 to 4 stops (depending on model).
That would mean
55 * 1.5 = 82.5 FF eq.
82.5 / 2 = 41.25 one stop (shooting at 1/focal, or 1/55, you're already covered)
41.25 / 2 = 20.625 two stops
20.625 / 2 = 10.3125 three stops

I believe that 1/focal length is a good place to start being cautious about your movements, irrespective of all the factors listed above.
Besides, I've actually shot a 50mm at 1/6 and they turned out reasonably sharp, and very sharp at 1/15, so a 1-stop expectation for someone who is just starting out seems reasonable.
