What am I doing wrong - Pictures attached

Take a look at these images.
Does this mean, I need to get a external flash or 50mm f1.4

I'm all for the use of external flash. In the second photo, your white balance is way off I'm sure. Unfortunately, no exifs attached so we cannot tell exactly what you are using. More information would probably help you get a better answer.

Take a good look at the backround lighting.

For the first shot, it says flash did not fire, for the second it shows AWB. I'm not sure if K-X automatically selects for flash when in AWB or if you have to set it to do so.
Regardless of that, the onboard Flash (or an external one for that matter) will give your pictures a harsh look without a diffuser.

In the second one, it doesn't say what focus point you were using but it looks like it's focused in front of the subject.

In both shots you have ISO 1600 which is giving you a long exposure. Set it to ISO 100 for flash.

Read up in the manual about Contrast, Saturation and Sharpness settings as well.


I'm moving this to Beginners Corner, the discussion will be more useful there.

Assuming your lens does not go below below f4, you need to higher your iso if you want to keep your expoure time fast to prevent hand shake. If you have a tripod, lower your iso and do long exposures like 1-2 seconds depending on the light available without overexposing.

I'm assuming you took those pictures without a tripod. Taking a shot at 1/30 requires a tripod unless you have a very stable hand.

Lastly adjust your white balance.

If you are using flash, lower the flash exposure to -1 so it doesn't come out too bright, put your shutter at 1/180 and iso 100. You would not need a tripod for this.

K-x does not have ISO 100.

Maybe I need to get a fast lens such as the 50MM f1.4 or Metz 48 flash.
I think the issue with "me" the end user, not the camera? Would you agree?

Lowest iso available to minimize noise since you have flash on.

Although 1.4 will give you few stops advantage in low light, you can take equally good pictures with your f4 if you used flash and adjust few setting with your camera properly. On the other hand in very low light situation where you do not want to use your flash then f1.4 is a must.

Another lens and a Metz 48 wouldn't have helped you here, getting the settings right would.

Aside from off WB in #2, and under exposure in #3, all three seem to have missed focus. How are you focusing? Are you using center spot and recompose?
