I was going to ask you the same question, because your issue seems pretty vague, so our answers are also vague. It's hard to tell if you are doing something wrong or the camera is.

Just to show how easy it is to do something wrong, I took these examples from my latest trip photos. I have a lot of experience but anyone can screw up or go beyond the limits of the camera. I think these represent the most common problems.

Focus problems and narrow depth of field:

This was a failed attempt to be artistic but a good example of bad focus. You can tell where the focus point is, and where it isn't. The out of focus areas don't show motion blur or camera movement. This is not autofocus failure - I focused manually, but I didn't look carefully enough at the viewfinder to get the parts I wanted in focus.

Subject motion (slow shutter speed):

The shutter speed is 1 second, so the fixed objects are sharp and moving objects are blurry. You can see moving stuff in all parts of the frame, so it's not a focus issue. Sharp stationary objects mean it's not camera movement. You can see some people are still enough even over one second. Also in a wide angle shot, distant motion doesn't look as blurry as close motion.

Camera motion (slow shutter speed)

The classic sign of camera motion is that everything looks shifted in one direction. If the shot has bright points of light, it's easier to spot. You can see that the building just looks blurry but the lights show you why. I was bracing the camera on a railing and shutter speed was 10 seconds. I took several shots because I knew 10 seconds was very optimistic, hoping to hold the camera still in at least one.

Overexposure:

When a digital sensor overexposes, you can't see or recover any detail in the image. That part just stays white, even if you darken the rest of the shot. This shot is not quite ruined, but it's so bright that parts must be overexposed. I should have noticed this and taken another shot at different settings.

Overexposure in just one channel, plus camera tilt:

The sensor has only 25% red pixels, 25% blue pixels and 50% green pixels. The meter (except in the K3) doesn't see color. In this shot, the blue stage lighting caused the blue channel to overexpose. You can see this before shooting by looking for a solid bright red or blue with lots of darker area in the shot. Neon, city lights, stage, etc. are obvious, but watch for flowers too, because the green foliage is darker than you think. You may see a lack of detail in the red or blue after taking the shot. The camera has an RGB histogram that shows each channel, also useful. In this case, I knew the blue channel was likely to overexpose but wasn't concerned because the stage wall wasn't important. However, I did not pay attention to holding the camera properly and tilted the shot by almost 3 degrees, which is bad.

Underexposure:

The shot is obviously too dark. The camera's meter may have been fooled by the patch of sky at the top. Watch for this because if you didn't really care about that sky being overexposed, you might not get any detail in the important parts of the shot. This shot can actually be processed to look fine. Underexposure is hardly an issue with the K-30 and similar Pentaxes.

Lens flare:

The big splash of light coming from the left is one type of flare. I was using the lens hood but it wasn't enough - on zoom lenses, the hood is a compromise and won't help all the time. This is also visible through the viewfinder when shooting so mostly my fault. Flare can also be bright colored spots or a trail of reflections from each lens element.

Finger in the shot:

My lame excuse is that the lens is very wide but come on, I should have seen that in the viewfinder.

A lot of these mistakes can be avoided by seeing them in the viewfinder first. The rest are predictable by some experience. They all could have been seen right in the field after taking the shot.

Thanks for giving this observation voice. I did not offer assistance because there was nothing to go with. If a person can't get reasonable results even using the basic instructions in the user manual, there is either a problem with the camera or the manual is in a language that the user has poor skills with.

At times I wish there was a sticky with the steps similar to those I suggested to a K-3 user with similar complaints:

It seems unlikely to me at this point that the camera is the problem, but if you are convinced that is the case, then it's probably time to try something else.

300 pages of manual & the photocorrection soft ware is same.
You don't have to read the entire 300 pages at one time; that will further confuse you. When I get a different camera, I choose the parts of the manual that address what specific thing I'm trying to do with the camera at that time. Over time, it ends up actually reading and understanding the entire manual.

Perhaps if you would be more specific as to why you are disappointed with the K30; such as images too light, too dark, out of focus, etc.;; then the members could offer more specific help.

BTW, the members here are most gracious, and will get you using & enjoying your K30, is you'll just share a bit more information on your photos from it.

Please share & be more specific as to why you are not happy with the camera! Just saying you're not happy, does not give the members anything to help them understand why you are not happy! Post some of the photos you do not like; at least that way more specific suggestions could be given. We cannot help when we don't know WHY you're unhappy with it!

Great post Dave. Very helpful for people starting out, and even people with some experience can learn something (I learnt about single-channel overexposure!).

Plenty of patient, polite and informative responses in this thread. PF is a good place.

Well, if I recall, you are using manual lenses. Have you set up the menu for focus peaking ?
Also, I question if you have looked at the manual or not, the K-30 has the ability to set up over/underexposure (The blikies) so your question is not correct in that regard. Of course, you need to be in live view for both focus peaking and over/underexposure indicators but I would assume you would know that since the OVF will not show either...or maybe you don't know that.

Less than a year ago,i asked a friend on mine buy me a Pentax K-30
from amazon co.uk.(cameramarket.co.uk) .
I chose Pentax because I still have the old manual lenses I can use.
However after 6 months I started experiencing this mirror problem.
The seller accepted to repair.
After one month,the camera was sent back to MALTA stating that nothing was wrong with the camera.
However,during the month stay at the seller,he did mention that they came
across the same problem.
I've used over the week-end and the same problem re-surfaced.

ANY HELP PLEASE?

THANK-YOU

HI DES & ALL,
THE PROBLEM IS THAT THE MIRROR GETS STUCK.
I USE THE OLD PENTAX MANUAL LENSES.
THAT IS WHY I BOUGHT PENTAX........K-30.
THE SELLER e.MAILED ME AND TOLD ME TO USE THE NEW "A"LENSES!
I DO NOT WISH TO BUY/USE SUCH LENSES.
THAT,FOR ME,GOES AGAINST THE PENTAX SPIRIT! YES?

ANY HELP OUT THERE,PLEASE?
THKS.
RGDS
