LOLWhat? :)

Already bugs and QC issues?

That's the Pentax I know, hahaha!
:P so there are bugs in firmware 1.0 or something like this?
who don't have bugs in firmware let trow first stone

That's what software version means nowadays, production 1.0 is actually just beta! >:-[
I agree there is a flaw in software industry conduct. (I'd even go MUCH further and claim there are many flaws, as a starter to the philosophy just google "defective by design") - but this is not about cameras, it is about software.

Lucky for us, hardware companies don't charge for firmware updates (other than software companies, who mark a bugfix as an upgrade and charge for it).

So you can buy a device and - at least for mass products - be reasonably sure that major flaws will be resolved by the time the firmware reaches the ripe old age of 2 years .... and you can update for free.

Still annoying, but a fact of life to be accepted.

I think point 1 and 2 are no bugs but well known features in Pentax land: unreliable PTTL and unreliable AF :)

"Features"?! :-o
@RichHigh... I'm confused... should I or should I not buy this camera? I'm already selling my K-x today and the K-5 is coming out here in Canada in just a few days...

Please let me know, what you think is best!

i think his opinion is that You need go to Canon
That depends. If you have many Pentax glass and want to keep at least one Pentax DSLR body, then you would need to re-purchase one eventually (unless you switch). Do take a look also at the K-r, which I think has more value for the money. The K-5 is better, but not far superior, IMHO. But it doubles the price.
For the guest asking to buy or not the K5: Yes, it is a very good camera and if you're going to use it, you'll enjoy it.
What says Rice here is something you can find everywhere on the internet: Flaming a product for 1 post in 1 random forum.
I've already a couple of friends that have bought the K5, I bought one myself, and did not find any of the problems listed in Rice's topic.
I don't know what is the point of a post like this. It is not the first in this blog, and I still don't get it... Spreading information that are not confirmed and find by only one or two persons...
There are a lot of people that already got their K5, and they are not posting anything geeks are looking for, they are shooting with their K5 and happy to do it.
1. Overexposure with 3 Different External Flashguns Except at ISO 100:
Update: the poster adds a bit later "my K-5 and flash now appear to be working correctly in P-TTL mode. I don't know why, because I didn't change any settings"

2. Out-Focusing and Inconsistency AF Issues with DA*55 and DA*50-135 SDM Lenses:
Great if the guy would post 1 image showing the problem - guess a troll

3. Un-Cooperative Auto ISO and Overexposure with Flash:
looks like a problem, although it's with a Metz flash ... it's a bit early to put the blame on the camera

The others are all computer translated, what for me means that I don't even try to read them because such a translation is still not really readable.

So i'm still waiting for my K-5

で買うの?買わないの?

You must really hate Pentax...
One thing for sure i know about this what they call BUGS/FLAWS whatever, are mostly (*not all*) USER ERROR and incompetence. Only way to solve this rumors for those who claim about flaws (wutever) is to READ THE MANUAL and (if you don't have a patience learning the camera) please admit that you don't know such function for some of features the camera have and ask for HELP. And then when you find the answer to what you're looking for you just silently says to yourself " oh ". @#$%@#$%#. be patient , read the manual, ask the forum , don't complain to the forum about what you don't know yet..... :(
buy a P&S (LOL)

Yes, those users just don't know how to use their cameras. Many of them own a K-7, and now a K-5. You must be the one smarter than them! Btw, do you have any of the cameras?
I guess more of them or some that i know of have this better images at low-light in the K-x body rather than the expensive K-7. Even until now K-7 still expensive and i'm expecting the price to go down since the K-5 comes out. But I'll still be glad knowing that K-7 retain its value after all i have one of this (got it at premium price as early adopter).

Hello, Ricehigh, thanks for the nice blog.
I have found one more bug.
If you are using Auto ISO with relatively high MAX ISO setting and shoot in bright are in AvHyper or TvHyper,
you cannot open your aperture till wide open even shutter speed is far below 1/8000, or you cannot slow down shutter speed till smallest aperture.
And, the value you can set is linked proportionally to the MAX ISO you have set.
i.e. if you change MAX ISO one step down, then you can open aperture one step further, or you can slow down shutter speed for one step.

I also found this issue in K-7, but in TvHyper only. And why not it became a big problem in K-7? MAX ISO setting is the point.
In K-5, far more higher MAX ISO is acceptable compared to K-7, that means you set much lower MAX ISO in K-7 compared to K-5,
and it means the slowest shutter speed is much slower than that of K-5.

Well, just try it in your room shooting to the lights.

In fast lens,
Auto ISO (higher the MAX ISO, faster the slowest shutter speed limit),
P-mode
and turn the front dial to left for TvHyper and slow down
then you will find that even the aperture is not hitting the limit such as F22, say F8 or so,
you will hit slowest shutter speed limit and you can slow down further.

btw, I love my K-5. It is great and have completely different feeling compared to K-7.
The but written above and small, tiny buffer memory are the only weak point I have found at the moment.

Hello, you're welcome. :-)

Back to the Auto ISO bugs you've mentioned, under those circumstances, just switch to manual ISO, so as to avoid all the troubles.
