The portrait has blown highlights and soft resolution. Why would they post something like that as an official shot? You'd think they could use the best possible glass and keep snapping until they get it right.

check the exif, it was shot in soft mode or at least converted that way, note the detail actually in the shot despite the softness, this is a classic Japanese style soft portrait, pleasing and printable.

It was also shot with the DA* 55mm lens that is now Pentaxes primere portrait lens. Take things into perspective here now and then realize it's aim is for their target audience.

Ok Now WHERE are the VIDEO SAMPLES!!!

For the days Pentax didn't listen to me and reacted and rectify their problems, their sales had been declining from year to year! Now, I guess they have done something right and I bet the sales will go up again!

I recall last time you continuously wrote everywhere and repeatedly, including at my blog, that the sales would remain unchanged no matter what I write at my blog and on the internet. So why now you've changed your tone? :-)
So this is partially admitting you purposely slammed Pentax in order to drive sales down and get your way???? Am I reading this right?
I never said you would cause sales to go up or down either way but I would believe that. One of the reason's I posted was to give another opinion. Weather people accepted yours or mine at least it gave them a choice. Something you seem adverse to. Like the old dpreview days where you accused others of being wrong because they disageed w/ you w/ facts to support their position. It wasn't you against me per se, but facts vs facts. Let others decide. Only a few times did I really JUST slam you for being... well, I'll behave (some jokes thrown in there as well). I still don't believe you are an engineer BTW. Sorry you still act like a wounded child....
So tell me and all here (and please publish your exposure charts that you calculated Pentax "underexposure" issue w/ lenses) What the peak in the histogram of a functioning meter in ANSI standards. 8 bit sRGB color space?
YOUR WORDS BELOW... How can I believe you w/ such a glaring deficiency in understanding even the basest metering concept??????

Now, we can get all the measurbation data that we, the measurbators, want. In the above screenshot, we can learn that the grey's peak is at 133. The peak of the central "peak" can be interpreted as the majority of value in the range (or the "mode" in statistical term). So, I would regard the exposure result is highly accurate, i.e. only 5 levels brighter than the absolute correct value of 128.
RiceHigh's (Pentax) DSLR and Lens Measurbation Page on Exposure Accuracy and More..

The correct answer is..... drum roll............
So, in the perfect world of a spot-meter calibrated to ISO standard and pure gamma = 2.2 transform of perfectly linear data coming from the sensor, the neutral surface should render 101 RGB if exposed according to the spot-meter;
Headroom in Highlights : Where is Zone V in The Digital World? | LibRaw
Again how can I ever believe you are nothing more than a squeaky wheel.......
BTW There are probably porn sites that get more hits a day then your blog in it's entire existence........ so what does that prove? Nothing.. squeak squeak.....
WOW, something I missed YEARS ago. Your chart actually had the correct MEAN. Your targets invalid, like I mentioned to you before (also years ago)... anyways, it's just all bad...

To explain your strange behaviour (and many other people like you as well), there is only one reason: you guys don't want to see any different opinions, or, just any "negative" opinions about Pentax, to put it straight foward!
I don't think that's the case at all.
The majority of posters here have posted they are somewhere between satisfied to overwhelmed with the K-7 from what they've seen so far.
Then you come here, as usual, and post negatively about it, and blame everyone else for not wanting to believe your negative comments.

Agree that everyone is entitled to their own opinion, but I say you try to force yours as gospel.

To me, it looks like a great piece of kit.
This Sunday, I will get to try it at an event in Tokyo.

A good selective quote on the last sentence of my last response and then turned it into a totally different subject. Well done, guy!

Back to your accuse (as usual for fanboyism symptom). Whats the problem of pointing out that all that four official samples are with +EV compensations applied for the metering? These are *facts*!

Well, here comes the problems again. You particular guys not even allowing any others to state *facts*, once these come out to be not so "favourable", in any ways!

Finally, just mind you that don't insult the wisdoms of other people. People whom read will make their own judgement. What "forced gospel" then??

Here we go again.. sorry to lie..

your own words and advice to yourself that you didn't keep....... Was that 2005??? Mods might as well lock this thread now..
Canon 300D + EF-S 18-55/3.5-5.6 @35mm

Last but not least, I really really hope that Pentax shall think and think again why this would and have been happened and why so many different users of *ist D and *ist DS have being reported (under)exposure problems. Truly speaking, Pentax really need to self-assess herself seriously in order to keep up. Otherwise, I bet that Pentax will disappear in the market very soon, and, my (and as all other old Pentax SLR users') investment on the Pentax lenses, will be surely in vain, under this circumstance. I really hope that Pentax can LISTEN to us, her customers and supporters. These are really my final words of advice, I think. Indeed, it is a rather disappointing thing that a considerably large amount of my pictures taken (in near 8000 shots) at quite some of my precious moments were underexposured. Most importantly, I think I had already tried my best to adapt to my *ist D s' light meter to get acceptable results, sometimes even in a hurry! Afterall, by having carried out quite some scientific tests and have published the results, I think I have also already helped Pentax more than enough. And, it really doesn't make any sense at all that Pentax's local service centre didn't have any way to test and not to mention to resolve the problem. So, I created and carried out my own tests by using all my own resources, including testing equipment and my valuable time, to find out the answer and hopefully some remedial measures, by myself.

Boy, thanks for recalling my old memory of my exposure measurbations and my homepage (which I almost forget these days)!

My "final words of advice" is that Pentax should *listen* and correct their error and to catch up, which are *still* valid up till now! Actually, I thought they have taken my advice!

Anyway, I would do the same exposure accuracy measurement once again after I get my K-7. No matter it will pass my test or not, I shall post the results. Thank you for your reminder!

Btw, the Canon EOS 300D passed my test easily and so far no Pentax DSLR can pass thro it. I hope the K-7 will be the first Pentax DSLR that will do it!

Bye bye.

Of course, I shall try to move and maybe somehow re-write those as "new" technical articles at my Google blogspot.com Blogger Host, which have been found to be very good and reliable in most aspects and it is just for "Free"!

Your welcome...
Yes it was a moral dilemma... I'd never discourage anyone from viewing an example of bad science...
I just don't encourage them to actually give it any credence.

Err, Rice? Those all look right.

With the dawn shot, I might have chosen to let the sky go, but I see no metering errors there: Those are all situations where I'd have metered off something less bright than the scene at large or comped the exposure about like that, both to the same effect, Perhaps you'd like a selection of scene modes?

Did you find the menu selection to turn down the K20d's LCD brightness that you complained about like it was a deal-killer, yet ?

The sample photos *of course* are exposing right. The point is not they are underexposed, but the light meter of the K-7 was deliberately set to +ve.

If it was not compensated, it would mean that very possibly the photos are underexposed. The scenes are not of high reflectance and very contrasty afterall. These samples came from a production K-7 with firmware 1.0. So, the possibility of underexposure tendency cannot be neglected.
