New Conundrum

I have another conundrum thread on the go in the lens Section, so then...
I now have a K5 and a K7 (Haven't actually used the 5 yet!)
Coming from Nikon I've had a hard time dealing with the Sensor in the k7 (Samsung?) Hellacious noise in shadows, I actually sent one off to Johnsons Photopia to have it calibrated and whilst it was away bought another! (Compared on it's return only to find out that they were the same!)Not very forgiving on the Sensor front and you really have to nail the exposure but i also found the Dynamic Range to be a bit more lacking than previous Camera's I had used. (Not by much but it's there!)
The K5 Sensor (Sony) Appears much more what I am used to, i love the ergonomics etc of the K7 and of course have them again in the K5. ilike to use primes and like to have two bodies for this. (so finally a drum roll!) K7 or Kr for a second body:

can't speak for the k7, but as a k10 user, I'm getting very clean images in the studio, so I'm assuming your talking about low light shooting... and I'd expect you'd be happier with the kx or kr than the k7

Yeah I'm thinking Kr as soon as they become available as a Body Only in the U.K. I think the Control Layout is Similar enough with obviously a few bits buried in Menu's as all the Manufacturers do! (Can't have all the toys in the Lower end stuff or they'd never sell any of it!)
Battery commonality did bother me a bit but I reckon I'll just get the AA holder for it, and I see the Kr won't use the Sensor shift to align the horizon (My mates who are all still Nikon Shooters marvel at that!) other than that is there anything glaring that you guys think I would miss from my K7 Before it gets sold down the river?

I think the K-r as a seconds doesn't make so much sense.
It doesn't offer anything over the K5 and the button layout is different.
The K5 and K7 have the same layout so easier to use together.
Also don't forget weather sealing, 100% prism viewfinder instead of a mirror viewfinder.

The Kr can take battery-pack as well, just like the K5 and K7.
And if you want you can use AA in an holder.

You mention 2nd body as you like to use 2 bodies at a time with primes, in which case, anything other than identical bodies, to me, is a waste of time. It's why we have 2x K-7s

Therefore the ideal 2nd body to a K-5 is a K-5.

A backup body is an entirely different proposition to a 2nd body though. In that case I would recommend a K-5!

You like the sensor and love the ergonomics so why confuse matters? Sell off the K-7s and get another K-5. If we had the cash, we'd do it without thinking.

Unlocker, I would love 2 bodies but Cash is the problem! Can't afford to buy another K5 until I get my Sorry Arthritic broken backed asthmatic apology of a body back into a job! Sorry digressing Like I say my choice is keep the K7 that I have trouble liking (Sensor is the only deal here!) Or get the Kr, which I can actually see uses for if I want to go real light, since it frequently causes me lots of pain if I carry a backpack too far My thinking is that I know I can get on with Sony Sensors since I've had a few, owning several Nikon Bodies and a couple of Sony's too. (Kr is still the Sony Sensor but updated right?) Second bodies with me tend to get set how I like and generally left with a Lens on a bit longer or shorter than the one I'm using just in case something presents itself. Stefan I think I'd be okay with one weather sealed Body but your comments on the ergonomics and such are moot to me...
Thanks for all the advice, I'm still finding my feet with Pentax (Bought a couple of Lenses I'm finding it hard to get on with too!) and want to do whats right for me and I know that only I can know that but I do like to throw ideas around and it's great to bounce them off others, something that required Flameproof clothing on the Nikon and Sony Sites I used to frequent...

It's only 150 gram lighter don't think you will really notice a big difference there and the size is roughly the same.

The thing is the K5 and K7 have a lot off buttons to access features directly but the Kr is pretty much menu based so the Kr will work differently than the camera's you've now.
Just saying so you know what to expect.

Do you actually need a second body?
Why not sell the K7 and spend the funds on a lens?

What lenses do you've and where do you use them for?

In that case I would keep the K-7 til you can afford the K-5.

Same grip
Same batteries
Same ergonomics
Same controls
etc. etc.

There is a lot to be said for keeping the basics the same, no confusion when hurried etc.

Cannot recommend that enough.

Stefan and Unlocker you are ringing bells!
Many thanks...

Many thanks to you two on helping me do the right thing, for me!
I think I'm starting to get the hang of the K7 and I think it's worth persevering with, as it can only make me a better Post Processor in the long run:
The light was sooo Bad yesterday! Forecast was for sunshine with light fluffy clouds, So I went to the English Lake District, which is only a short bus ride away for me. That'll teach me to believe the Met Office! Didn't bring me Tripod so All these are with the k7 and Limiteds at between 1/6th and 1/20th of a second handheld, SR Works...
























Last two shots are of Nab Ghyll near Rydal Mount Hall, Actually put my foot in that one! Brrr...

No problem Jules, glad to help!
