So why now is the camera producing such excellent results, could it be that sensors don’t perform properly when brand new? My Fuji's S9600 and S602 were also a disappointment to start with but with no in camera changes making any difference they both improved with use.

This is one of the most astonishing comments regarding photography I have ever come across. But hey, I am just a newbie so you will have to excuse me if I am wrong.

It just doesn't make sense.

Have you ever wondered that may be you have learnt to expose the images better? I can guarantee you that any shifts in exposure makes a world of difference. Unless you are extremely good at PP then any minor flaws in exposure will show it ten folds. You would have to be extremely good in PP in order to hide those flaws even then, never completely.

Nail that exposure and you will notice a world of difference in your shots. I could bet my bottom dollar that its rather that the reason why you have better images now with your K7 compared to before than any stuff such as you mention about sensors being new and not performing well etc etc

Steady on there Amin! It was only a question from the poster.

But you are right about correct exposure and optimum quality. I still reckon an excellent way to find out how good we are is to shoot a slide film.

What You Take Is What You Get and it shows up every defect in composition and exposure. An excellent exercise that everyone could well benefit from trying at least once.
Best regards, John

That's exactly how I learnt my lesson . After a few films I started giving more attention to details and exposure levels, rather than shooting and then tweaking and then shooting again, until I would find the correct exposure.

I think that after 2 years on the forum we can safely say you are no longer a "newbie" Amin.

It's not difficult to explain. Practice makes perfect!

Glad you're now getting good results, Mr Robinson.

How's life on HMS Steadfast George? You've been absent for a while.

I'd rather assume that practice helps to improve. No one is ever going to say perfect with respect to an image. Might say that about the content but not the image.

Seriously though David this forum IS just like one big happy family, I reckon most of the members here would rate it as the best forum on the web, stick around and you'll soon get to know the various regulars and their little idiosyncrasies (ouch! thats a big word, my brain hurts now)

Glad you got the K7 Sorted

Still in the boatyard, I regret to say. Been here so long they're thinking of putting me on the payroll.

And Mr Robinson, newcomers to photography (rather than snappery) often are "idiots", in the sense of being ignorant of some of the finer, and often not so fine, points. How could they not be?

Indeed, it is not uncommon for newcomers to photography to think that if their results fall short of their expectations, then it must be the equipment to blame, not themselves. Sometimes they are right, but on occasion, their views prove to be mistaken.

In your case, you appear to be saying (and forgive me if I have misunderstood) that the improvement you are experiencing is the result of some kind of spontaneous repair to the camera. My own view, as expressed above, is that you are simply getting better at using it.

Finally, I think you are unwise to start jumping to conclusions about the nature of this forum on such brief acquaintance. If you stick around you will find that all is usually sweetness and light. Even Dougf8 isn't such a bad chap, once you get to know him.

Best wishes

I have just bought my first DSLR the K7, upgrading from a Fuji 9600s. I bought it with the kit lenses 18-55mm WR and 50-200mm WR. Up to now I am unimpressed with image quality. I have tried changing settings to ensure ISO stays low but I still find images are noisey grainy and with poor sharpness. AF Focus seems to be accurate when using view finder, anti shake is ON. I have tried alternative sharpness settings etc but see no improvement with image quality. What am I doing wrong or is it due to the KIT lenses? If so do they cause image noise associated with high ISO even when ISO is set to no more than 200?
The K-7 is not a stellar performer but it should be better than you're apparently seeing. Remember the P&S cameras apply a lot of processing automatically to get the result you see. With a DSLR like the K-7 it's up to you how much processing you do & how you want the image to look. Don't think that as you've bought a good camera it will do it all for you. On the contrary, it's much more up to you.

First of all I would shoot in RAW (my preference is for PEF but DNG will do just as well). Then process your photo as a PEF (or DNG) file which gives the maximum latitude & will yield the best results. Then when all processing is done save for printing as a jpg file.

Having said I shoot in RAW as PEF files on the weekend I attended a dance rehearsal where I started shooting in RAW but decided to change to jpg. BIG mistake. The jpg's were nowhere near as good as the PEF files. Of course if I set my in camera processing to get the best out of jpg files I might have been happier but the plain fact is that the jpg files just didn't come up as well.

If you'[re worried about processing all these RAW files & converting to jpg I have found that the "Process Multiple Files' command in Pentax Digital Camera Utility 4 does an excellent job of bulk conversion producing pleasing results with minimum input from me.

I think it's fairly obvious that the OP doesn't appreciate the need to do post-processing. Until he does, he's not going to get the best from his camera.

And this is the problem with the pictures posted by Dougf8, which can serve only to reinforce the OP's view that the camera is not much good.

What the OP needs to see is what the camera is capable of when everything is done properly. Sadly I don't have a K7 so can't oblige.

And Doug, lighten up. My post was in response to your over-sensitive reply to somebody else.

By the way, note that JR sharpens in-camera only because of the requirements of Fotolibre. Normally, the best advice is to leave all adjustments at zero, and do what is required on your computer.

Finally, the "photo" in photography means light. You have to know what you are doing to produce good pictures in poor light.

I too had my fare share of problems with the K7 when I first got it three months ago, you may remember I bought two and returned one and bought a K5 because I thought it to be soo bad! After a while however you learn the Sensor so to speak, and given a bit of time it will reward you. You have to expose Bang on there's not too much forgivness here but it's worth learning...

I never had any problems getting quality images straight out of the camera on my DL2! Have been considering upgrading to K7 or K5, but this sort of problem is very offputting.Why should an entry level DSLR be more proficient at doing a good job in camera than a high end model? And with only 6 million pixels! I know there are no doubt very good answers to this, but nonetheless, it is a point. I really would like the build quality, the lovely viewfinder and LCD screen of a K7,but do not fancy spending hours at PP to get a decent image! I am sorry, but I do strongly feel that high end DSLR'S should be able to produce decent JPEG'S without having to spend hours on a computer.

I have a DL2 and have always obtained fine images straight out of the camera. I have considered upgrading to a K7 or K5, but find the comments regarding image quality on the K7 rather offputting. Why should a so-called entry level camera be so much better at producing decent JPEG'S than a high end model? No doubt there are plausible answers to this. I love the look of the build quality, the viewfinder and quality LCD screen of the K7, but I do not fancy having to spend hours on a computer just to be able to get a decent image!

Don't be put off I've had no problems with my K7, I find it quite amazing that when the K7 was launched is was regarded as a good camera, all of a sudden the K5 comes along and the K7 takes a bit of a slating.

I'm ordering a K5 next week not because I think the K7 is a bad camera (I'm keeping it) but I do a lot of wildlife and sports photography so the 7fps, faster focussing and high ISO performance are too tempting.
